The search of alternative products for tomato bacterial spot has been promoting by the lack of effectiveness registered by the traditional products available. The objective of this work was to evaluate a range of chemical products by in vitro tests, in experiments seedlings and field experiments. The products studied were: acibenzolar-S-methyl; benzalkonium chloride; phosphite; copper hydroxide, copper oxicloreto; metiram + pyraclostrobin and famoxadone + mancozebe. The in vitro tests were carried out at Embrapa Hortaliça, Brasília-DF, in July of 2007. The bactericide action was evaluated on Xanthomonas perforans and X. gardneri. The trial was in a complete randomized block design with four replications and plot was constituted by a Petri plate impregnated with solidified bacterial suspension. The halo of inhibition formed was evaluated. The experiments with seedlings were carried out with the hybrid Heinz 9553 at the commercial nursery VIVATI in Rio Verde, Goiás, in August to September and November to December of 2008. There were three trials in a complete randomized block design with three replications. The products were sprayed by using CO2 portable sprayer. The inoculation occurred 29 days after sowing, with an isolated of X. gardneri. Disease severity was evaluated on 15 leaflets per plot at 14 and 16 days after inoculation of the first and second experiment, respectively. Data was expressed as percentage of leaf affected by program Quant. It was also suggested a possible interaction between the regulator of growth paclobutrazol and the behavior of certain products in the reduction of the severity of the disease. Two field trials were carried out at the experimental farm of Unilever Bestfoods, in Goiânia-GO, from February to June of 2007 and April to August of 2008. The first was with the hybrid Heinz 9992 in a complete randomized block design, with 15 treatments and three replications, and inoculated with X. perforans. The second was in a split plot completely randobized block design with three replications. Variety (Hypeel 108 and U2006) was ascertained for factor A and the 10 treatments for factor B. Xanthomonas perforans and X. gardneri were inoculated in different moments. In both trials foliage severity, number of fruits with symptoms and yield were evaluated. In the second trial fruits with sun scald was also taken. In the in vitro test, the products to which X. perforans and X. gardneri were sensitive in the recommended dose were the benzalkonium chloride and famoxadone + mancozeb. Methiram + pyraclostrobin had action in the dosage recommended only for X. gardneri. Xanthomonas perforans was sensitive to this product only starting from ten times more. The products of copper base did not have action in the bacteria at the recommended dose, being sensitive only at a hundred time more. For the trials of seedlings it was noticed that metiram + pyraclostrobin, copper oxicloreto, famoxadone + mancozebe, phosphite and copper hydroxide reduced the severity under certain conditions. In the field trials, in generally, acibenzolar-S-methyl and famoxadone + mancozeb lead to the better results.

(Universidade Federal de Goiás, 2010-02-26) Alves Filho, Anibal Sebastião; Dornelles, Milton Sergio; http://lattes.cnpq.br/9601151044965568; Leandro, Wilson Mozena; http://lattes.cnpq.br/9052207260053937; Ximenes, Paulo Alcanfor; Borges, Jácomo Divino; Barros, Rosana Gonçalves; Menezes, Luiz Antônio Silva; Leandro, Wilson Mozena
The savannas reached prominence in the development of corn (Zea mays L.), soybean (Glycine max L.) and processing tomato (Lycopersicum esculentum Mill.), Depending on the economic and social importance of these crops. The problems of acid soils and nutrient deficiency in the savannas are common in most soils, but once overcome these obstacles, the cultures exhibit satisfactory development and production. Increasingly it becomes necessary, by the dynamism that modern agriculture provides that alternative mechanisms of replenishment of nutrients to the soil are offered, due to the high cost of fertilizer and high extraction of these elements in each cycle of crops. The use of industrial waste from various sources has shown potential for agricultural use, for purposes of correction of acidosis, addition of macro and micronutrients to the soil or even physical conditioning of the soil, always under careful criteria used to avoiding the environmental contamination. The aim of this study was to evaluate the effect of the electric arc furnace dust coming from the steel industry as a source of micronutrients in crops of corn, soybean and tomato at different levels of liming. The tests were conducted in two locations. A field experiment was conducted at the experimental farm of the School of Agronomy and Food Engineering, Universidade Federal de Goiás, Campus Samambaia, in Goiânia-GO, Brazil and other, in a greenhouse at Palmital Farm, municipality of Urutaí-GO, in campus of the Instituto Federal Goiano. During three years, were evaluated in Goiânia-GO, the use of steelmaking dust in corn in rotation with soybean and, in Urutaí-GO, for seven months, the tomato crop in succession with soybeans. The results in both experiments indicated that the levels of heavy metals detected in soil and leaves of the plants analyzed were below the limits considered toxic.

Producing seedlings of good quality is an important step in the process of planting forest species. Addition of lime and fertilizers contribute in obtaining good quality seedlings, however, information is limited on fertilization and nutrition of native species of savannah. The objective of this study was to evaluate growth response of baru seedlings (Dipteryx alata Vog.) to organic and mineral fertilizers. Seedlings were produced in plastic bags with a diameter of 20 cm x 30 cm and capacity of four liters of substrate. Clay Dark Red Latosol collected from subsoil (20 cm depth) from Federal District of Planaltina, DF was used. The first experiment was conducted in complete randomized blocks, with eleven treatments in a factorial arrangement (4X2), with three replications (composed of seedlings coming from different matrix) and plots consisted of three seedlings. The treatments tested were E0+D0, E10+D0, E20+D0, E30+D0, E0+D1, E0+D2, E0+ALL, E10+D1, E10+D2, E10+ALL and E20+D1, where: E0, E10, E20 and E30 are doses of cattle manure varied from 0 to 30% in relation to final volume of mixed subsoil; D1 and D2 are traditional rates of chemical fertilizers, and D2 is double of D1 and D1 equivalent to dolomitic lime incorporated in the subsoil (0,5 g L-1) + P (150 mg L-1) + K (200 mg L-1) + Zn (5 mg L-1) + Cu (5 mg L-1) + Mn (5 mg L-1) + B (1 mg L-1) + Mo (0,5 mg L-1) + N (50 mg recipient-1 month-1, diluted in water); P and K were applied in the form of triple superphosphate and potassium chloride, respectively, Zn, Cu and Mn in the form of sulfates, B and Mo in the forms of borax and sodium molibidate, respectively.; ALL is symbol of slow release fertilizer in six months (2.4 g recipient-1 after emergence of seedlings and five months of age), contain N (15%), P2O5 (10%), K2O (10%), Ca (3,5), Mg (1,5%), S (3%), B (0,02%), Cu (0,05%), Fe (0,5%), Mn (0,1%), Zn (0,05%) and Mo (0,004%). In others experiments (1, 2, 3, and 4) baru seedlings were submitted to four rates of dolomitic lime (0.0, 0.5, 1.0 and 2.0 g L-1 of substrate), P (0, 150, 300 and 600 mg L-1), K (0,100, 200 and 400 mg L-1) and N (0, 50, 100 and 200 mg seedling-1 month-1), in combination with two rates of cattle manure (10% and 20% in relation to final volume of mixture with subsoil). These experiments were conducted in complete randomized blocks in a factorial arrangement (4x2), with three replications (composed of seedlings coming from different matrix) and plots consisted of three seedlings. Source of N was urea (45% N), P triple superphosphate (45% P2O5), and K potassium chloride (60% K2O), respectively. After eight month of seedlings age following observations were made: Stem diameter of 5 cm height, plant height, top dry matter, soil and leaves chemical analysis for each treatment combination. In the first experiment, baru seedlings presented positive response to addition of traditional chemical fertilizers (rates D1 and D2) and slow release (ALL). Organic manure improved growth of seedlings with the addition of 20% and 30% cattle manure, however there was no difference between two rates. All treatments tested permitted production of seedlings of good quality for commercial sale and planting in the field, except of control treatment without fertilization (E0%+D0) and which received only 10% cattle manure with addition of subsoil (E10%+D0). Organic manure (20% cattle manure) and mineral fertilizers (D1, D2 and ALL) increased fertility of the substrate and leaf concentrations of N, P, K, S and Zn. In the experiments 1 and 4, seedlings presented positive growth to cattle manure incorporated in the subsoil, rate 20% better than rate 10%. Incorporation of cattle manure in the subsoil in the dose of 20%, supplied adequate fertilization in the substrate and foliar nutrition for growth and mineral nutrition of baru seedlings. In the presence of cattle manure incorporated in the subsoil in the 10 and 20% rates, seedling growth response was negative with the addition of potassium and there was no response with the addition of lime and phosphorus. Nitrogen topdressing monthly gave positive response to growth and height, stem diameter, top dry weight, when applied after incorporation of cattle manure in the subsoil in the dose of 10%, but response was positive in relation to height with rate of 20% cattle manure.
Adubação orgânica em sistema agroflorestal: atributos químicos e físicos do solo e desempenho das espécies consorciadas
(Universidade Federal de Goiás, 2021-02-25) Andrade, Carlos Augusto Oliveira de; Leandro, Wilson Mozena; http://lattes.cnpq.br/9052207260053937; Collier, Leonardo Santos; http://lattes.cnpq.br/7449368697500123; Collier, Leonardo Santos; Calil, Francine Neves; Flores, Rilner Alves; Freitas, Gilson Araújo de; Silva, Átila Reis da
The insertion of barueiros in the production systems through agroforestry system SAFs can promote the integration of rural areas in the Cerrado, especially when combined with crops of high relevance for farmers in this region, preserving natural resources and providing additional income for producers. Due to the integration of different crops, whether through consortia, successions or crop rotation, the demand for nutrients can be intensified, causing greater dependence on mineral fertilizers, which increases production costs. Organic fertilization can be a lower cost strategy to supply the nutrient demand for SAFs, in addition to contributing to the maintenance of the system's sustainability. The aim of this study was to evaluate the changes in different doses of organic compost in the chemical and physical attributes of the soil and in the development of crops grown in an agroforestry system in the Cerrado of Goiás. The experiment was conducted in a SAF composed of barueiros, divided into six rows of 14 trees, with banana trees and agricultural crops grown between the rows. The experimental design was in randomized blocks with 6 treatments and 4 repetitions. The treatments consisted of four doses of organic compost (5, 10, 20 and 40 Mg ha-1), a treatment with mineral fertilization, plus the control without fertilization. The chemical and physical attributes of the soil, the agronomic performance of cowpea and banana and the growth of cassava and baru trees were evaluated. The applications of organic compost promote positive changes in the chemical attributes of the soil, especially in the first layers, with increased levels of MOS, P, K and Mg compared to mineral fertilization. During the studied period, the doses of organic compost and mineral fertilization did not affect the physical attributes of the soil to a depth of 0.20 m. The organic compost formed by energy cane biomass and cattle manure shows potential as an organic fertilizer in the cultivation of cowpea and banana cultivated in an agroforestry system, being able to substitute at 100% the mineral fertilization in the nutrition of these cultures. Doses 20 and 40 Mg ha-1 of organic compost provided the greatest increases in the vegetative performance of cassava, equivalent to mineral fertilization. During the period studied, mineral fertilization and doses of organic compost did not affect baru growth.
Alternativas de manejo de Meloidogyne enterolobii Meloidogyne incognita em tomate industrial
(Universidade Federal de Goiás, 2018-11-22) Silva, Juliana de Oliveira; Rocha, Mara Rúbia da; http://lattes.cnpq.br/4660306671671575; Rocha, Mara Rúbia da; Santiago, Débora Cristina; Araújo, Fernando Godinho de; Pinheiro, Jadir Borges; Puerari, Heriksen Higashi
Root-knot nematode (Meloidogyne spp.) is one of the main phytosanitary problems that hinder the cultivation of tomato (Solanum lycopersicum L.). Among the species of the genus Meloidogyne, M. incognita stands out as the most important species for the tomato crop. Another species that has caused concern to the producers is M. enterolobii, due to its ability to develop in cultivars with resistance to other species of Meloidogyne. For an adequate control of these plant parasites it is necessary to adopt an integrated management using practices such as resistant cultivars, biological control, resistance induction, chemical control, among others. This study had the objective to evaluate the reaction of tomato genotypes to M. enterolobii and the effect of chemical and biological products on resistance induction of tomato plants to M. enterolobii. We also evaluated the efficiency of three non-fumigant nematicides on the M. incognita control in tomato plants. the development of nematodes and the histological modifications caused in the root cells of plants when treated with these products and evaluating three new non-fumigant nematicides in the reduction of the population of M. incognita in tomato. Twenty-one tomato genotypes were inoculated with 2000 eggs and J2 of M. enterolobii and kept in a greenhouse for 35 days after inoculation (DAI) were used. All genotypes tested showed a susceptibility reaction to M. enterolobii. Four tomato genotypes were submitted to treatments with Bacillus subtilis, Bacillus licheniformis + B. subtilis + Trichoderma longibrachiatum, Acibenzolar-S-Methyl (ASM) and Extract of Reynoutria sachalinensis, inoculated with M. enterolobii and evaluated 60 days after inoculation. The plants that received the treatment with B. subtilis presented greater development of aerial part and root. The ASM resistance-inducing agent was able to reduce the reproductive factor when applied to the PXT 408 genotype. Seedlings of cultivar H-9553 were inoculated with 2000 M. enterolobii eggs and J2 and treated with ASM; B. subtilis; B. subtilis + B. licheniformis + T. longibrachiatum and Extract of R. sachalinensis and collected at 5, 10, 15, 20, 25, and 30 DAI for nematode penetration evaluation and histology of tomato root cells. In the evaluation of the nematode development and cell histology, the use of R. sachalinensis showed efficiency in the reduction of fourth stage juveniles and galls in the plants at 20 DAI and in the reduction of the final population of the nematode and reduced the number of females per gall. All the plants infected by the nematode, regardless of the treatment, presented vascular cylinder displaced from the center of the structure of the roots. Tomato seedlings of the Red Gnome cultivar were submitted to treatments with fluensulfone, fluopyran and fluazaindolizine and inoculated with 5000 eggs and J2 of M. incognita and evaluated at 60 DAI to determine the efficacy of the products used. The new nematicides tested showed efficiency in the reduction of the M. incognita population in the tomato roots.
Aplicabilidade do sistema de avaliação da aptidão agrícola das terras frente à realidade do processo produtivo agropecuário goiano
(Universidade Federal de Goiás, 2008-02-27) BORGES, Lino Carlos; OLIVEIRA, Luiz Fernando Coutinho de; http://lattes.cnpq.br/5499109407814908
There are several works which aim to equate the agricultural production in function of the best use of natural resources as soil and water, in the attempt of obtaining the maximum of effectiveness in the productive system, and upon this context the evaluation of the potential of using the lands has major importance for a correct planning of agricultural activities. The elaboration of maps of agricultural aptitude is of extreme importance for the sustainable use of soil and water, it should be the first and more important instrument of agricultural planning. Because of this, the elaboration of those maps should be accompanied of a discerning methodological process, focused mainly in the socioeconomic aspects aiming to adequate it to the various levels of soil handling present nowadays. This work has as objectives: 1) Research the applicability of the evaluation system of the lands agricultural aptitude regarding the actual conditions of the agricultural productive process for two areas of the State of Goiás, basin of drainage of Córrego das Pedras and of Ribeirão Jurubatuba (nascent of Ribeirão João Leite) and of the immediate surrounding of the National Park of Emas; 2) Look for latent factors responsible for the large variability of the lands aptitude in the studied areas, and detect the similar samples considering this clustering, using for this multivariate techniques of factor analysis of principal components and discriminative. The work considers quantifying and comparing the elements of production among the various classes of agricultural aptitude, establishing qualitative differences among those aptitude classes and the handling levels, comparing the theoretical model proposed in the studies against the several realities of the researched areas. The data related to the soil types, agricultural aptitude and handling levels recommended were gathered from maps elaborated for the two areas being studied. Data regarding productivity, production costs, land value, gross revenue and local adopted technology were obtained from personal visits and direct interviews with a sample of 52 farm properties for the agricultural year of 2006/2007. Based on the information found in the 52 analyzed samples, the use of factor analysis was shown to be promising, for this study area, being an innovative aspect in the interpretation of data related to the agricultural aptitude. Two techniques of statistical multivariate analysis were used: factor analysis aiming to reduce the columns of the original matrix (variables in study) through the identification of latent factors, synthesizing the common information over all variables; and the discriminant analysis with the objective of classifying the observations, with known data. These analyses indicated that productivity and production cost are related and that a possible explanation for it may be due to the levels of handling and technology, as with the gross income it may be explained by other elements as the business opportunity, market value for the products, and not necessarily with the level of technology. It was verified also a need for establishing greater and more meaningful details regarding the handling levels for the cases of pasture and forestry. Because of the peculiarities and diversity of production systems found in the basin of Ribeirão João Leite, the system of agricultural aptitude of the lands proposed by Ramalho Filho & Beek (1995) was considered insufficient, for suggesting only three handling levels, while the dispersion of the data regarding production, productivity, production cost and gross revenue, demonstrates the need of better discrimination or hierarchization of the handling levels. For the area of the immediate surrounding of the National Park of Emas the system of agricultural aptitude was shown to be more appropriate on the handling levels recommended. The system proposed by Ramalho Filho & Beek (1995), in a certain way, plasters or limits the expectations one could have relative to the potential of certain cultures, soils and used labor force, regarding the productivity and profitability of some agricultural and forestry activities. It was verified also that the handling levels are extremely important, and they should be in greater number and more detailed than the existing 3 handling levels (A,B and C) proposed by Ramalho Filho & Beek (1995).

(Universidade Federal de Goiás, 2019-02-11) Vasconcelos, Luis Henrique Costa; Silva, Flávio Alves da; http://lattes.cnpq.br/1713250447051507; Vera, Rosângela; Morgado, Cristiane Maria Ascari; Caixeta, Lismaíra Gonçalves; Campos, André José de; Silva, Flávio Alves da
The 'Dekopon' tangerine is a little known fruit in the consuming community, and emerging in research, nevertheless gains space within the citrus culture for its agronomic and sensorial characteristics, opening market for mandarins. The objective of the present work was to evaluate the application of calcium chloride in pre-harvest and post-harvest of 'Dekopon' tangerine, with associations of processing, refrigeration, passive modified atmosphere and ultraviolet radiation C. The study was carried out in a commercial orchard and the fruits analyzed in the laboratory. For the pre-harvest treatments, different doses of calcium chloride (100, 200, 300 and 400% of the recommended dosage) were used for the post-harvest, the association with UVC radiation was used (control and 10 minutes of exposure), processing (presence and absence of processing) and passive modified atmosphere (control, PVC and LDPE); and thereafter, all UVC radiation times (0, 3, 6 and 9 minutes) and refrigeration (24, 12 and 6 ° C). Loss of fresh mass, color (ºHue and chroma), soluble solids, hydrogenation potential (pH), titratable acidity, ripeness index, geometric characteristics, ascorbic acid, firmness and fruit fractions were evaluated. The data originated from the quantitative variables analyzed were submitted to regression analysis by means of an F test at the 5% probability level to measure the meaning of the proposed model, while the data originated from the analyzed qualitative variables were submitted to analysis of variance (P <0.05), and when significant the Scott-Knott averages comparison test was done at 5% probability. Based on the results, it was concluded that the use of pre-harvest calcium chloride, for most variables, desirable post-harvest characteristics were observed for 100 and 200% of the recommended CaCl2 dosage during 21 days of evaluation . While the beneficiation did not act in a beneficial way, but the association between ultraviolet light and passive modified atmosphere, they acted to maintain postharvest attributes at room temperature. And, refrigerated storage at 12ºC allowed for the maintenance of desirable post-harvest characteristics, allowing the fruit to be preserved for a longer period, physical and physicochemical quality with higher stability, and longer shelf life associated with this storage the UVC radiation time of 3 minutes, showing promise in the maintenance of adequate post-harvest quality.

(Universidade Federal de Goiás, 2016-03-03) Souza, João Maurício Fernandes; Casaroli, Derblai; http://lattes.cnpq.br/1054839770814863; Alves Júnior, José; http://lattes.cnpq.br/3418524049655817; Giongo, Pedro Rogério; Bufon, Vinicius Bof; Evangelista, Adão Wagner Pêgo; Brian, Alexandre; Casaroli, Derblai; http://lattes.cnpq.br/1054839770814863
To realize an efficient management of water use in irrigated agriculture is important to obtain meteorological information to assist in the management of water resources. Since the data of evapotranspiration (ET) they are often used as a fundamental criterion in irrigation operations in the calculation of water balance and agroclimatic zoning. Therefore, the estimated evapotranspiration of culture on a regional scale, based on satellite images represent a great contribution to the studies on the management of water resources, being able to provide their estimate in areas with high heterogeneity and size, to Unlike micrometeorological methods and even of direct measures such as lysimeter. Compared to other models that use the energy balance, the SAFER (Simple Algorithm for Retrieving Evapotranspiration) has a simpler parameter, requiring only the remote data of the albedo, NDVI and temperature. The SAFER still has the additional advantage of using data from both types of stations meteorological conventional and automatic. This feature is important because it allows the assessment of historical trends of energy balance components on a large scale over the years,given that automatic sensors are relatively recent developments in instrumental technology. Considering the recent development of SAFER, there are not many studies to assess its performance. The aim of this study was estimate the culture evapotranspiration and their respective Kc's in its different phenological phases without water restriction, in areas in Goias Cerrado region, using remote sensing techniques for validation of the agro-meteorological model SAFER (Simple Algorithm for Evapotranspiration Retrieving) in compared to the method standard FAO 56. , using agrometeorological monitoring and after evaluation of the model's reliability, make a comparison between the ETr estimation method obtained by SAFER,with the climatological hidric balance and the soil water balance in order to validate the proposed methodology as an alternative to methods traditional. The structure of this study is as follows: after the introduction and literature review on the topic, the first chapter presents the SAFER calibration data and its application in bean crop, tomato, sugarcane and wheat in Goias Cerrado, taking as reference the water requirement estimates using the FAO methodology; and then, after proof of efficiency, in the second chapter presents the SAFER application results in a dry area cultivated with sugarcane in order to present it as an alternative to traditional methods
Aproveitamento de lodo de curtume e uso de água residuária de esgoto doméstico na cultura do milho (Zea mays L.)
(Universidade Federal de Goiás, 2015-01-19) Pinto, Guilherme Malafaia; Araújo, Fernando Godinho de; http://lattes.cnpq.br/4958960432206028; Leandro, Wilson Mozena; http://lattes.cnpq.br/9052207260053937; Leandro, Wilson Mozena; Borges, Jácomo Divino; Salomão, Leandro Caixeta; Araújo , Fernando Godinho de; Ramos, Marcus Vinícius Vieitas
In this study, we carried out several experiments under protected environmental conditions, which, as a whole, aimed at the assessment of tannery sludge reuse in corn culture (Zea mays L.). In the first study (cultivar BG 7049H), chemical changes and corn yield in Haplic Plinthosol were assessed. The soil received 9 and 18 Mg.ha-1 of tannery sludge (in natura) and was irrigated with domestic wastewater. Such treatments helped increase pH values and total P, K, Mg and Ca concentrations in relation to initial values, thus improving soil fertility. However, the application of these doses, even if together with wastewater irrigation, did not provide a corn yield equivalent to that obtained with mineral fertilization. The second study involved vermicomposting of different tannery sludge doses with cattle dung. The potentiality of such treatment method in agriculture was assessed. The results showed that vermicomposts produced using Eisenia foetida presented different nutrient concentrations, favoring their use as soil conditioners. On the other hand, despite C/N ratios decreased in all treatments, indicating the maturation of the final substrate, the values observed exceeded the maximum limit established by MAPA’s Normative Instruction # 025/2009 for compound organic fertilizers, fact that led to the development of the third study of this Ph.D. thesis. The objective of this study was to detail the investigations on vermicomposting of tanning residues, using two different types of tannery sludge (liming and primary), which were also mixed with cattle dung. At the end of the experiments, vermicomposts yielded high N, P and K total concentrations, as well as pH values and C/N ratios, and N and TOC concentrations that comply with the minimum limits established by MAPA. Besides, Cu, Zn and Cr concentrations in the produced vermicomposts did not exceed the limits established by Conama’s re solution 375/2006. A fourth study followed, aiming at the analysis of a corn culture (cultivar LG 6036) in a typical Dystrophic Red Latosol (Oxisol), irrigated with domestic wastewater and adding tannery sludge vermicomposts produced in the previous study. Although the treatments promoted satisfactory soil conditions for the development and yield of corn, little or no increase in pH, EC, TOC, base saturation, OM, N, K, Cu and Fe concentrations were observed, when compared to concentrations initially identified in the soil. On the other hand, an increase in P, Ca, Mg, Mn and Zn concentrations was observed especially in the treatments that included irrigation with domestic wastewater and/or addition of tannery sludge vermicomposts. Thus, it is concluded that, contrarily to tannery sludge concentrations used in natura, tannery sludge vermicomposts plus irrigation with domestic wastewater constitute important nutrient sources for corn culture. However, we call attention to the use of these residues aiming at the possibility of increasing certain nutrients in soils, once no significant increase was observed for all elements assessed in the culture soils.
Aspectos da biologia e manejo do nematoide de cisto da soja
(Universidade Federal de Goiás, 2013-07-04) Araújo, Fernando Godinho de; Rocha, Mara Rúbia da; http://lattes.cnpq.br/4660306671671575; Rocha, Mara Rúbia da; Melo, Patrícia G. Santos; Campos, Hércules Diniz; Ribeiro, Neucimara Rodrigues; Meyer, Maurício Conrado
Soybean is the most important oilseed crop grown in the world and Brazil is the second largest producer. Many pest problems can affect soybean, including the soybean cyst nematode, Heterodera glycines. The search for efficient management alternatives of this nematode and understanding of their biology have been largely studied, but still lacking information. Experiments were conducted under greenhouse conditions and naturally infested field aiming to better understand the behavior of H. glycines and to propose management alternatives. The first study had the purpose to evaluate the penetration and life cycle of H. glycines, race 3 (HG Type 0 -) in soybean cultivars resistant (BRSGO 8860RR) and susceptible (BRS Valiosa RR) under greenhouse conditions. Evaluations in stained roots were made at 2, 4, 6, 9, 12, 15, 18, 21, 24 and 30 days after inoculation (DAI). The penetration of H glycines occurred throughout the period of evaluation in both cultivars. The H. glycines life cycle was completed in 15 days, both in the susceptible and resistant cultivars. Resistant cultivar had the peak period of formation of J3, J4 and females delayed in comparison with the susceptible cultivar. The second study aimed to evaluate effectiveness of the resistance to H. glycines under high inoculum concentration, and the effect of increasing inoculum rates on the penetration of juveniles and H. glycines survival. Two experiments were conducted using three soybean cultivars (BRS Valiosa RR, susceptible to H. glycines; BRSGO Chapadoes and BRSGO 8860RR, both resistant to H. glycines) under four inoculum concentrations (1.000, 2.500, 5.000 and 10.000 eggs and J2 per plant). The increase in the H. glycines inoculum concentration increased the final nematode population in the susceptible cultivar. The cultivar resistance was not affected by high inoculum concentration. The root penetration of J2 increased as the inoculum concentration increased regardless the cultivar. The survival rate was higher in the susceptible cultivar decreasing with increasing of inoculum concentration. The third study evaluated the effect of seed treatment two soybean cultivars (resistant BRSGO 8860RR and susceptible BRS Valiosa RR). Two experiments were conducted, one in a naturally infested field and other under greenhouse conditions. The seed treatments did not affect the stand and the plant height of the resistant soybean cultivar. There was no effect of seed treatments on the nematode population in the field experiment. Under greenhouse, seeds treated with abamectin (50 and 75 mL a.i. 100 kg seed-1) + thiamethoxam (70 mL a.i.), imidacloprid + thiodicarb (105+315 mL a.i.) and thiodicarb + imidacloprid with carbendazim + thiram (75+225 e 30+70 mL a.i.) reduced the number of females per gram of roots on the susceptible cultivar. Seed treatment with imidacloprid + thiodicarb (75+225 mL a.i.) also reduced the number of eggs per female on the resistant cultivar BRSGO 8860RR.

The study was on the effect of agroecosystems in common bean (Phaseolus vulgaris L). The objective was to evaluate phytotechnical aspects and soil quality in agroecosystems using legumes in monoculture and intercropped with millet system and conventional tillage in the common bean. The legumes studied were beans pork (Canavalia ensiformes), Crotalaria (Crotalaria juncea), Mucuna (Stizolobium dierrigianum) , Guandu (Cajanus cajan) in monoculture and intercropped with millet (Penicetum glaucum) under conventional and no-tillage system. The experiment was conducted in a randomized block design. Dry biomass, nutrient content, nutrient accumulation of plants for roofs, growth (height and stem diameter) of plants, yield of common bean and the physical , chemical and biological soil properties were evaluated . It was found that all legumes in monoculture and intercropped with millet provide high accumulation of nutrients in the biomass, contributing to the improvement of soil fertility and crop productivity in the common bean agroecosystem , the production of dry biomass cover crops were exceeding 9.000 Mg ha-1 , stood out the pigeon pea and bean Mucuna with the largest production fitomasssa and levels of N, P , Ca , Mg and Zn. The cropping system -tillage and legume consortium with millet allow better growth of the common bean. The yield of common bean was high for all systems, the highlight was the bean pork with the highest yield. The soil physical properties were not affected by agroecological systems. Chemical and biological soil properties were altered with high accumulations of nutrients supplied to the ground in agroecosystems. The system was used as a cover crop showed the lowest metabolic coefficient, and the system more efficient.

The behavior of the herbicides in the environment is not determined solely by the physicochemical characteristics of the products (pKa, Kow, vapor pressure, water solubility and etc.). Soil attributes (CTC, organic matter, texture, mineralogy, pH, etc.), environmental factors (temperature, rainfall, winds) and the practices adopted in the production systems (cropping system, vegetation cover, chemical fertilization Or organic) also affect the behavior of herbicides in the environment. The objective of this work was to evaluate: 1 - The effect of the soil type on the activity of the herbicides clomazone, diclosulam, oxyfluorfen and sulfentrazone and to determine the ideal dose of this herbicide in each type of soil, through dose- answer; 2 - The activity of the herbicide Oxyfluorfen in soil with addition of biochar of sewage sludge; 3 - The activity of pre-emergent herbicides, in the absence and presence of Pennisetum glaucum straw. The soil type affected the the herbicides activities and, therefore, should be considered when deciding the herbicide applied doses. In Cerrado soils CEC is the most suitable soil attribute to predict the ideal herbicides doses of oxyfluorfen. The addition of biochar from sewage sludge obtained by pyrolysis at 500 ° C increased the sorption of the herbicide Oxyfluorfen to the soil, reducing its availability to the plants. The herbicide efficacy of the herbicides atrazine, clomazone and diclosulam is negatively affected by the presence of straw of Pennisetum glaucum. The presence of straw of Pennisetum glaucum does not affect the effectiveness of the herbicides Oxyfluorfen and Sulfentrazone.

Based on the premise that the replacement of native forests by agroecosystems impacts the soil, were studied different forms of soil use compared to a fragment preserved forest. The study was conducted in an Entisol Quartzipsammentunder the family agriculture use for 22 years, managed under: SAF – Agroforestry system, PA - Pasture, RT - Slash and burn field and MA - Preserved forest. The management impacts on the soil were estimated by the changes in the accumulation and quality of the soil mulch and by the changes on the physical and chemical indicators of soil. The collect of soil mulch, the soil resistance to penetration, until 40 cm depth, and the collect of deformed and undeformed soil samples, for of physical and chemical analyzes, collected in seven repetitions for each system, layers 0-5, 5-10, 10-20 and 20-40 cm depths for two consecutive years and in two sampling periods (July 2010/2011 and January 2011/2012). The variables analyzed were: accumulation of soil mulch and its nutrient content, carbon stock on soil mulch and the soil, plant residue quality index, soil organic matter, soil acidity, exchangeable bases, cation exchange capacity, bases and aluminum saturation, strength penetration, bulk density, porosity and soil aggregation. The results showed that soil use with agroforestry system, even after 22 years of use, little differentiates itself from the preserved area. The conversion of forest in agroecosystems enhances the soil chemical properties and significantly reduces the stocked carbon in the soil mulch compartment, as noted in the “slash and burn” field. The soil use with pasture for successive years increases bulk density, strength penetration, microporosity and reduces soil macroporosity. In this study, clear distinctions between the forms of use and soil management were observed in stocks of litter on the soil surface and strength penetration.

Upland rice cultivation under no-tillage has shown low productivity when compared to conventional tillage, requiring further technological adjustments. This study aimed to identify which attributes of an Oxisol of the Cerrado are most affected by successive rice crops under no-tillage and which is the set of these attributes that correlates to rice yield, in order to establish the most suitable soil conditions for this crop. In February 2011, in areas cropped with upland rice under no-tillage system by one, two and three years, respectively, at Santo Antônio de Goiás, GO, rice grain yield was determined and soil samples were taken from soil layer of 0.00 - 0.10 m of an Acric Red Latosol to determine soil physical, chemical and biological attributes. Multivariate analysis techniques were applied on data obtained and it showed that rice crops cause changes in all soil attributes compared to the forest, with the exception of K and Cu contents, metabolic and microbial (qMIC) quotients and microbial biomass N: total N relationship (MBN:N). These attributes and Mn content are responsible for discriminating the areas under successive rice crops. The physical attributes are very similar among areas. Cu and Mn contents are higher in the area with one year of rice cultivation, as well as qMIC and MBN: N. The metabolic quotient increases with the years of rice cultivation, which indicates an increase in stress or disorder condition in the soil microbiota. Rice grain yield is positively correlated with total nitrogen, copper, iron, manganese, microbial biomass carbon and nitrogen contents, total enzymatic and acid phosphatase activities, microbial quotient and MBN:N relationship, and negatively correlated with microporosity and metabolic quotient. Based on multiple linear regression analysis, the soil attributes that together better explain the grain yield were copper, iron and microbial biomass nitrogen contents and acid phosphatase activity.

Rice cultivation upland stands out in the Cerrado region and on the climatic conditions of the region, management studies of nitrogen fertilization become essential for greater efficiency in the use of this nutrient. The aim of this study was to evaluate the response of cultivating upland rice BRS-Emerald to different nitrogen sources and doses in the Brazilian Cerrado. The experiments were conducted in Goiânia, GO in the agricultural years of 2013/2014 and 2014/15 in Oxisol. The experimental design was a randomized complete block in a factorial 3x4 + 1 (3 fonts, 4 doses and control without N) with four replications. The nitrogen sources used were conventional urea (Uconv); urea treated with NBPT® urease inhibitor (NBPT) and coated urea Kimcoat® polymers (N+) tested in doses 30, 60, 90 and 120 kg ha-1 of nitrogen in rice upland BRS Esmeralda spacing 0.5 m between rows. For the characteristics evaluated nitrogen source NBPT was superior to other sources in the development of rice cultivar BRS Esmeralda. For the characteristics evaluated the soil quality bioindicators little or nothing were influenced by nitrogen source, the biomarkers were more influenced by the planting period and doses of nitrogen applied.

The presence of an arboreal component, such as in agroforestry systems, can promote a better balance of tropical ecological processes, allowing agricultural exploration in vertical and horizontal landscape profiles. This, together with the inclusion of single or intercropped cover crops in the agroforestry understory can increase the beneficial effects through interaction among species, favoring greater nutrient accumulation and cycling. Therefore, the objective of this research was to evaluate the soil chemical attributes and the performance of agricultural species and cover crops in rotation/consortium in an agroforestry system in the cerrado region of Goiás. The research was carried out between 2012 and 2016, in the city of Goiânia-Goiás, in an agroforestry system implanted in an 8- year-old Baru forest (Dipteryx alata V.). Soil from the experimental area was classified as typical dystrophic Red Latosol. The experimental design was randomized complete block (RCB), with four replications. Cover plants were cultivated singly: Pigeon pea (Cajanus cajan); Stylosanthes cv. Campo Grande (Stylosanthes macrocephala - 20% and Stylosanthes capitata - 80%); Massai grass (Panicum maximum) and intercropped: Pigeon pea+ Massai grass and Stylosanthes + Massai grass, in addition to an area under spontaneous vegetation (control treatment). We evaluated soil chemical fertility and dry phytomass productivity and macronutrient accumulations by cover crops, quality and yield of corn silage grown in rotation with the cover plants, relative index of chlorophylls and growth of Banana trees cultivated in consortium with the cover plants, in addition to the growth of the Baru trees during this period (height, diameter at breast height and crown diameter). The Campo Grande Stylosanthes increased the calcium contents, pH values and sum of bases in the soil solution at depth 0-10 cm after two years of cultivation. However, Massai grass, alone, increased potassium levels at depth 0-10 and 10-20 cm in the same cultivation year. The dry matter yield of silage maize was similar among the residual straw of Pigeon pea, Massai grass, and Stylosanthes + Massai grass cultivars. However, cultivation with residual Stylosanthes increased the crude protein percentage. The growth in height of the banana trees at 6 and 12 months was higher in consortium with Massai grass when compared to the area maintained with spontaneous vegetation. The incremental increase in height of Baru trees only increased after two years through the residual Campo Grande Stylosanthes. The highest productivity of dry phytomass was obtained from Massai grass, alone. The accumulations of nitrogen, phosphorus, calcium and sulfur were similar among Massai grass alone, Stylosanthes alone, and Massai grass + Stylosanthes consortium. However, potassium and magnesium accumulations were only higher in the aerial part of the Massai grass, alone.

In the state of Goiás, its 34 million hectares, only 0.93% represent the Conservation Unit (UCs) full and 2.59% UCs of sustainable use, among these protected areas are the parks. Law Nº. 9985 of July 18, 2000, establishing the National System of Nature Conservation Units (SNUC) is made up of all federal conservation units, state and municipal. This Act establishes criteria and standards for the creation, implementation and management of protected areas. The protected area is the territorial space and its environmental resources, including jurisdictional waters, with relevant natural characteristics, legally instituted by the Government, with conservation objectives and defined limits, under special administration regime, to which adequate safeguards apply to protection. This study aims to evaluate the effect of fire on the chemical and physical properties of soil in a protected area in an urban area, which has preserved area and kills suffered burning process. The study was conducted in the Botanical Garden Amalia Hermano Teixeira (JATH) located in the southern region of Goiânia, Goiás, has a total area of 1,000,000 m2. The soil was classified as Oxisol. In JATH were selected two areas for the study: Burnt Forest (MQ), the area which suffered from illegal burning process in 2010; Preserved forest (MP). Its vegetation is characterized as primary forests have changed, the type Forest Semideciduous. Soil sampling was done at two different times: MQ in September 2012 and MP in May 2013. native forest areas are used as reference areas for soil studies. Thus were estimated physical and chemical indicators of soil penetrometer with up to 40 cm and samples of disturbed and undisturbed soil for the purpose of physical and chemical analysis. Soil samples were collected at depths of 0-5, 5- 10, 10-20 and 20-40 cm. In each area were soil samples collected form a sample grid consists of six rows and five columns with a distance of 10 m between sample points, forming a gride 300 m2. Data were subjected to analysis of variance (ANOVA) and the means were compared within each depth and in each area by 5% Tukey test. The results showed that after four years of the forest burning, observed a concentration of nutrients in the soil profile of MQ in relation to MP at a depth of 0-5 cm. The levels of potassium, calcium and magnesium, present in higher mean values MQ relative to MP, which can be attributed in part to the effect of residual ash. The time after firing do not influence so means the physical soil.

There were studied attributes related to sugarcane production in the organic cultivation system aiming to evaluate the efficiency of this system. There were evaluated the soil fertility, the nutrition and productivity of sugarcane and the impacts of the production system on the stocks of carbon and nitrogen on soil. There were analyzed the following attributes of soil fertility: organic matter (OM), soil chemical reaction (pH), potential acidity (H+Al), aluminum (Al3+), sulfur (S), cation exchange capacity (CEC), base saturation (V), aluminum saturation (m), phosphorus (P), potassium (K), calcium (Ca) and magnesium (Mg). In order to establish the crop nutritional status and its productivity: total number and total production of stalks, carbon (C), nitrogen (N) e and C/N ratio of the plants, straw production, production of dry matter and the extraction of P, Ca, Mg, K, Fe, Zn, Cu and Mn. The impact of sugarcane cultivation on the soil was evaluated through the soil density (Sd), content and stocks of carbon and nitrogen on soil. Regarding the fertility and nutritional status of sugarcane it was studied the following chronosequence of cultivated areas in the organic system: Org.0 – area cultivated under conventional system, representing the beginning of the organic system cultivation; Org.2 – area cultivated for 2 years in the organic system; Org.6 – area cultivated for 6 years in the organic system; Org.10 – area cultivated for 10 years in the organic system. There were evaluated also two different situations that may occur in any production system: one area where it occurred an accidental burn, Org.2Q – area cultivated for two years in the organic system with an accidental burn and other area where the sugarcane plantation was grown for twelve years and since then it was not reformed and replanted, being cultivated for ten years in the organic system - Org.10SR. In the study of impact of sugarcane cultivation on soil it was excluded the area Org.6 because the clay content in this area was inferior to the others. One area of native cerrado (CN) was used as reference for the calculated stocks of carbon and nitrogen. The soil (Oxisol), and plant samples, were collected in plantations belonging to Usina Jalles Machado, Goianésia – GO. The design was entirely randomized with five repetitions. The soil was collected in the following depths: 0-5, 5-10, 10-20-, 20-30, 30-40, 40-60, 60-80 and 80-100 cm, December 2010. The vegetal tissue was collected in February 2011. The organic cultivation was found more efficient than the conventional one of sugarcane. There was a rise up on the levels of fertility of the soil and of productivity. The extraction of nutrients of the soil was higher in the organic areas, which require special management of fertilizing to avoid weakening of the soil. Regarding the tillering and productivity, it was verified that in the beginning of the conversion to the organic system, after two years, there was reduction of tillering, however with no compromising of the final productivity of the plantation. The plants cultivated in the organic system absorbed more nutrients than in the conventional system. The soil density reduced highly in the superficial layers. In the organic system the carbon stocks raised considerably in relation to the conventional cultivation.

Theobjective of this research was to study the morphometric and phenological development, and production of Eugenia dysenterica DC., from different municipalities in Goiás Southeast and grown in experimental area of the Escola de Agronomia of Universidade Federal de Goiás, featuring physically and chemically their fruit and the fatty acid profile of its seeds, and to evaluate the chemical composition variability of the essential oil extracted from its leaves, with the aim of better understanding, expansion and use of this native. For morphometric analysis, semiannual readings of the total height of the trees were made, crown insertion height, crown diameter, length, and proportion of canopy projection index, coverage ratio, formal crown and stem diameter at 10 cm soil. The phenological observations were carried out fortnightly being evaluated phases leafing, flowering, fruiting, leaf abscission, budding and fruit production. The harvests of 2013 and 2014 the fruits were chemically physical and evaluated for weight, longitudinal and transverse diameter, number and weight of seeds / fruit, pulp mass, skin color, juice yield, total soluble solids, pH, titratable acidity , moisture, ash, protein, lipids, carbohydrates, mineral nutrients and fatty acids in seeds. The essential oil extracted from the leaves cagaiteira was evaluated for yield and seasonality and different groups of plants. Climatic data were obtained in the First Class Evaporimétrica station in operation at EA / UFG. There was a wide variation between plants regarding the morphometric variables analyzed. The plants presented is still under development, an increase in height and diameter, however, with medium to low growth, and with slim canopy format. The cagaiteira loses its old leaves in August and September, and the issuance of new leaves occurs throughout the year, peaking in August, September and October, by which time there is also the sprouting stage, flowering and fruiting. Fruit production is considered irregular between plants and switching production between years. The fruits of cagaiteiras are considered irregular as to its physical format, with biometric variation between vintages. The cagaitas pulp apresentoa relevant value for N, P, K, Ca, Mg and S. The cagaitas seeds have a profile of fatty acids, mostly, linoleic acid, oleic acid and palmitic acid. The yield of essential oil extracted from cagaiteiras leaves was low, and therefore the main chemical constituents belonging to the biosynthetic class of sesquiterpenes. Of the 30 compounds identified in the essential oil, only five of them corresponded to more than 60% total of the oil extracted from the seeds, they being a-copaeno, (E)-cariofileno, a-cumuleno, g-cadineno e d- cadineno. The highest yield of essential oil occurs in the rainy season and dry / rain transition, and what are the main chemical constituents also occur in higher percentage in these times.
