Item Biodisponibilidade de herbicidas pré-emergentes em solos andinos e seus impactos na produtividade da soja(Universidade Federal de Goiás, 2025-02-27) Almeida, Danielle Resende; Calixto, Wesley Pacheco; http://lattes.cnpq.br/9073478192027867; Damin, Virgínia; http://lattes.cnpq.br/7413922413797454; Damin, Virgínia; Correa, Gilmarcos de Carvalho; Leandro, Wilson MozenaThe efficacy of weed control by pre-emergent herbicides depends on the physicochemical characteristics of the molecule, soil attributes, environmental factors, and management practices adopted in the production system. Pre-emergent herbicides can cause phytotoxicity in soybean plants, leading to reduced productivity. Therefore, it is crucial to invest in solutions that ensure better herbicide selection, adjusting the dosage according to soil type while considering the target crop and the history of weed infestations in the area. This approach enables effective weed control without compromising yield. Given this context, the objectives of this study were: 1- To evaluate the bioavailability of the herbicides sulfentrazone, flumioxazin, metribuzin, imazethapyr, and diclosulam in weakly weathered soils; 2- To assess the phytotoxicity and residual control of the pre-emergent herbicides diclosulam, imazethapyr, metribuzin, sulfentrazone + diclosulam, and sulfentrazone at different doses in soybean cultivation. Soil types influenced both the efficacy and phytotoxic potential of the studied herbicides. The herbicides imazethapyr and diclosulam required dose reductions in all tested soils. However, in soil S/A11, the sulfentrazone dose needed to be increased from 200 g a.i. ha⁻¹ to 221.75 g a.i. ha⁻¹, while flumioxazin required an increase from 57.6 g a.i. ha⁻¹ to 95.27 g a.i. ha⁻¹ to achieve 90% control. In soil LE/C6, the flumioxazin dose had to be increased by 103.59% compared to the label recommendation. Furthermore, in soils LE/C6 and H/B22, no dose reduction was observed for sulfentrazone and flumioxazin, respectively. Regarding productivity, differences were observed only among herbicides, with the lowest yields recorded in the diclosulam and metribuzin treatments. Cucumber, wild poinsettia (Chamaesyce hirta), and weed control improved from 15 DAA, influenced by soil moisture. By 90 DAA, all herbicides remained persistent in the soil.Item Biologia de Rachiplusia nu (Lepidoptera: Noctuidae) na cultura da soja e utilização de baculovírus para seu controle(Universidade Federal de Goiás, 2024-12-16) Alencar, Anna Gabriela Gomes de; Godinho, Karina Cordeiro Albernaz; http://lattes.cnpq.br/0894467127708959; Czepak, Cecilia; http://lattes.cnpq.br/7900255230781858; Czepak, Cecilia; Rezende, Janayne Maria; Andrade, Rizia da SilvaEmbargada.Item Avanço no método LAMP para a detecção de Xanthomonas spp. no processo de produção de mudas de tomateiro do segmento industrial(Universidade Federal de Goiás, 0025-02-25) Machado, Juliana de Farias; Duval, Alice Maria Quezado; Ferreira, Adriane Wendland; http://lattes.cnpq.br/7196405181790361; Ferreira, Adriane Wendland; Duval, Alice Maria Quezado; Rossato, Maurício; Ferreira, Enderson Petrônio de BritoEmbargadoItem Aspectos epidemiológicos do mofo-branco em feijão comum(Universidade Federal de Goiás, 2013-03-26) Santos, Priscila Ferreira dos; Lobo Junior, Murillo; Lobo Junior, Murillo; Cunha, Marcos Gomes; Paula Junior, Trazilbo José deEmbargadoItem Sistema silvipastoril com forrageira e pequi (Caryocar brasiliense Camb.)(Universidade Federal de Goiás, 2013-03-26) Wisintainer, Carolina; Seleguini, Alexsander; Seleguini, Alexsander; Collier, Leonardo Santos; Brasil, Eliana Paula Fernandes; Benett, Cleiton Gredson SabinEmbargadoItem Ação de Trichoderma spp. em colônias de saúvas Atta sp. em laboratório(Universidade Federal de Goiás, 2025-02-28) Freire, Karoliny Zarreta Santos; Pereira, Jaqueline Magalhães; Pereira, Jaqueline Magalhães; Fernandes, Paulo Marçal; Fujihara, Ricardo ToshioEmbargado.Item Rizobactérias benéficas na promoção de crescimento em arroz de terras altas (Oryza sp.)(Universidade Federal de Goiás, 2025-02-27) Duarte, Gabriella Alves; Nascente, Adriano Stephan; http://lattes.cnpq.br/3194091518396388; Nascente, Adriano Stephan; Reis, Karina Freire d'Eça Nogueira Santos dos; Filippi, Marta Cristina Corsi deEmbargado.Item Novos padrões físico-químicos de bebidas a base de fermentados de jabuticaba(Universidade Federal de Goiás, 2025-02-26) Ribeiro, Juliana Rosa; Ferreira, Tania Aparecida Pinto de Castro; http://lattes.cnpq.br/0312123979235562; Souza, Eli Regina Barboza de; http://lattes.cnpq.br/7641431808466123; Souza, Eli Regina Barboza de; Vera, Rosângela; Leandro, Wilson MozenaEmbargada.Item Folhelho de Caiapônia como suplemento de magnésio para as culturas de milho Zea mays (L.) e soja Glycine max (L.)

In the case of systems that integrate crop and livestock (iLP) there is a great concern for problems in physical properties and water the soil resulting from cattle trampling and machinery traffic. The objective of this study was to characterize the physical and hydraulic properties of an Oxisol managed under ILP in Goias Cerrado, using for that physical indicators of soil quality (soil bulk density, porosity and penetration resistance), limiting water range (LLWR) and the index S. The study was conducted in an experimental area of Embrapa Rice and Beans in iLP. The treatments were: Forest = Cerrado; iLP = Soy, Past. 1, Past. 2 and Past. 3, pasture with 1, 2 and 3 years of implementation time, respectively. Disturbed and undisturbed samples were collected in the layers 0.0 to 0.10 and 0.20-0.30 m. In the deformed specimens was determined texture, carbon content and soil fertility. In undisturbed soil samples were determined: soil bulk density (BD), water retention curve in the soil and penetration resistance (PR), which were subsequently used to calculate the IHO and the index S. Soil management with iLP affected the soil physical properties in relation to the Mata, observed by the increase in Ds, microporosity and RP and reduced macroporosity and total porosity. The soil physical behavior described by the IHO and the S were similar. Both demonstrated a degradation of soil physical quality in iLP regarding Woods, observed by low values of IHO S and for these treatments. They point to a structural soil degradation with the implementation of agriculture and a gradual improvement of soil physical quality with the set pasture deployment time, mainly by low IHO S values and the Past. 1 and higher in soybean and Past. 3, with Past. 2 showing intermediate values. The IHO indicates a severe structural soil degradation, the two layers evaluated for the treatment Past. 1 which can be attributed to recent traffic of agricultural machinery and implements for planting and harvesting practices in the area. The S-value indicates soil physical degradation to the Past treatments. 3, the first layer, Past. 1 and Past. 2 in both layers. Thus, these two indicators efficient to describe and quantify the effects of changes in soil structure by management with iLP in the Cerrado region. The management of soil under iLP was an efficient model in improving soil structure, mainly by the resilience and the beneficial effect of root used pastures.Item Biodisponibilidade e efeito de herbicidas pré-emergentes na microbiologia em solos do Cerrado(Universidade Federal de Goiás, 2025-02-21) Silveira, Isabella Nunes da; Damin, Virgínia; http://lattes.cnpq.br/7413922413797454; Marques, Letusa Momesso; http://lattes.cnpq.br/7154180150340351; Marques, Letusa Momesso; Silva, Ilca Puertas de Freitas e; Calil, Francine NevesHerbicides are applied and reach the soil, Herbicides undergo processes of sorption, transport, and transformation when applied and reach the soil, as well as their activity are affected and impact the environment. In this context, the aim of this study was to evaluate the bioavailability and microbiological impacts of diclosulam, imazethapyr + flumioxazin, pyroxasulfone + flumioxazin, S-metolachlor, and trifluralin in three Cerrado soils. Five experiments were conducted separately for each herbicide or combination in a greenhouse, using a completely randomized design in a 3 × 8 factorial scheme with five replicates. The factors included three soil types (LVAd – Rhodic Haplustox, RQo – Typic Quartzpsamment, LVd – Rhodic Haplustox) and eight herbicide doses (0, 1/16x, 1/8x, 1/4x, 1/2x, x, 2x, 4x) tested on Eleusine indica and Conyza bonariensis. Phytotoxicity (%F), plant dry matter and weed control percentage (%C) were determined at 35 days after application (DAA). To further evaluate the effects on soil microbiology at 35 DAA for the doses 0, x, and 2x, microbial biomass carbon (C-BMS), basal microbial respiration (RBS), and metabolic quotient (qCO2) were determined. Phytotoxicity (%F) was influenced by the interaction between herbicide and soil for all molecules. For diclosulam, imazethapyr + flumioxazin, pyroxasulfone + flumioxazin, and S-metolachlor, the soils exhibited similar responses, with symptom severity increasing with higher doses. The lowest %F values were observed for trifluralin, which nonetheless exceeded 80%. Results showed that weed control percentage (%C) was influenced by the herbicide-soil interaction for diclosulam, imazethapyr + flumioxazin, S-metolachlor, and trifluralin, while pyroxasulfone + flumioxazin was affected only by the herbicide. Trifluralin was ineffective in controlling Eleusine indica. Diclosulam, imazethapyr + flumioxazin, pyroxasulfone + flumioxazin, and S-metolachlor demonstrated potential for dose adjustment in the control of Conyza bonariensis and Eleusine indica, with the optimal dose varying according to soil type. In soil microbiology, diclosulam influenced C-BMS. RBS and qCO2 were affected by soil type, with RQo showing the lowest RBS and highest qCO2 values. The imazethapyr + flumioxazin mixture affected qCO2, with higher values observed at lower doses in RQo. Soil type increaswed C-BMS and RBS, with the highest C-BMS values recorded in LVAd and LVd soils, while the lowest RBS was observed in RQo. Pyroxasulfone + flumioxazin and S-metolachlor did not significantly affect the evaluated parameters. It was concluded that herbicide effects varied depending on the molecule and soil type.Item Prospecção de supressores biológicos da mancha de bipolaris do milho(Universidade Federal de Goiás, 2025-02-26) Franco, Leandra Gonçalves; Nascente, Adriano Stephan; Filippi, Marta Cristina Corsi de; Filippi, Marta Cristina Corsi de; Nascente, Adriano Stephan; Araújo, Leila Garcês; Elias, Marina Teixeira ArrielConteúdo embargadoItem Diversidade de Fusarium spp. causadores de podridão radicular do feijoeiro comum(Universidade Federal de Goiás, 2015-05-25) Abud, Lidianne Lemes Silva; Wendland, Adriane; Lobo Junior, Murillo; Lobo Junior, Murillo; Cunha, Marcos Gomes da; Wendland, Adriane; Silva, Silvana Petrofeza daNinety-six Fusarium isolates retrieved from soil samples collected in the Brazilian states of Paraná, Minas Gerais, São Paulo and Goiás were investigated, in order to identify the species complex that causes root rots in common bean. The first study consisted of pathogenicity tests and identification at the species level of 24 isolates from each state, which comprise the main growers of this crop in Brazil. Root infection was assessed by the inoculum layer method, in a completely randomized design with five replications. In addition to disease incidence, root rot severity was estimated according to a disease rating scale and McKinney index. Statistical analysis consisted of Shapiro-Wilk test, analysis of variance, and mean separation by Scott-Knott test, both of them at 5% of significance. All isolates caused root rot symptoms in common bean seedlings, with two different groups of disease severity. The species identification was carried out in carnation leaf-agar medium and optical microscopy, and by sequencing of the Tef-1α gene. Sixty five isolates were identified as Fusarium solani, 27 as F. oxysporum and three as F. proliferatum, according to morphological descriptors and DNA similarity above 95%, in comparison to reference sequences deposited in GenBank and Fusarium-ID database. The distribution of species and disease severity of were not linked to the geographical origin of the isolates. A second study aimed to estimate the physiological diversity of F. solani and F. oxysporum isolates according to the assimilation profile of 95 different carbon sources, assessed in FF Biolog microplates. Each Fusarium isolate was evaluated in duplicate, with 100 l of a suspension of 2 x 105 conidia ml-1 adjusted in phytagel sterile solution deposited in each microplate well. Each isolate was evaluated in duplicate, after 72 hours of incubation in the dark at 25°C, with absorbance assessed at 750 nm. This test followed a completely randomized design, with a 2 × 4 × 95 factorial arrangement, for evaluation of individual factors (species, isolate origin state and C source) and their interactions. The results were submitted to analysis of variance, with averages compared by Scott-Knott test (5%). Metabolism of C sources was also analyzed by descriptive statistics and by principal component analysis, to identify the main causes of variation and correlation between variables. The results showed differences between the metabolic profile of F. solani and F. oxysporum and between the geographical origin of the samples, with isolates from Goiás forming a clearly distinct population from the other states.Therefore, it was found that 100% of the isolates were pathogenic to common bean, and that the three species (F. solani, F. oxysporum and F. proliferatum) form a pathogen complex distributed in different Brazilian states. The physiological differences between F. solani and F. oxysporum suggest that these species may inhabit different soil niches, and that carbon sources assimilation profile can be used to identify species and populations adapted to different environmental conditions.Item Efeitos da aplicação do herbicida glifosato na microbiota de solo hidromórfico do cerrado(Universidade Federal de Goiás, 2013-11-20) Souza, Marco Aurélio Pessoa de; Anunciação, Carlos Eduardo; Campos, Alfredo Borges de; Campos, Alfredo Borges de; Brasil, Eliana Paula Fernandes; Vieira, José Daniel Gonçalves; Anunciação, Carlos EduardoThe microorganisms in the soil are largely responsible for biogeochemical cycles. For this reason, their survival depends on many environmental factors. The ability to synthesize compounds and degrade harmful substances is large, and for this reason can be used as environmental technologies for decontamination of environments. In flooded soils, the environment is further restricted by the decay of oxygen and so the microorganisms acquire the ability to use other chemicals alternatively soil instead of oxygen as electron acceptors to promote your metabolism. In the presence of pesticides, the development of the microbiota can be affected, sometimes by the toxic action of the organic molecules, either by stimulationg specific groups of organisms. Little is known about the effects of pesticides on microorganisms in hydromorphic soils subject to prolonged flooding and saturation. The aim of this study was to evaluate the effect of glyphosate on soil microorganisms hydromorphic soil of the Cerrado under anoxic conditions. This study was conducted indoor at the Universidade Federal de Goiás (UFG), using hydromorphic soil of the preserved Vereda, of the Cerrado Biome. The samples were collected in the field at a depth of 0-15 cm and received four treatments ( 0 ; 1L/ha ; 12 L / ha and 100 L / ha of glyphosate ) in triplicate . To reach the anoxic and anaerobic incubations was built in biogeochemical reactor inert atmosphere . Daily measurements and measurements of CO2 in five days throughout the incubation period (1, 3, 7 , 15 and 30 days) pH , ORP , microbial biomass and plate counts were performed under inert atmosphere using the reactors and a glove bag . Results showed a trend of first dose of glyphosate ( 1L/ha ) have an inhibitory effect on the microflora and the higher doses ( 12 and 100 L / ha ) a stimulus effect when compared to the control and the first dose .Item Diversidade e funcionalidade de Bacillaceae em sistema plantio direto e diferentes tipos de plantas de cobertura(Universidade Federal de Goiás, 2025-02-24) Almeida, Laura Cristina da Silva; Okura, Monica Hitomi; Lobo Junior, Murillo; http://lattes.cnpq.br/3352833548668460; Lobo Junior, Murillo; Mendes, Rodrigo; Filippi, Marta Cristina Corsi deEmbargoItem Comparação entre bases de dados para mapeamento e modelagem em bacias hidrográficas(Universidade Federal de Goiás, 2015-02-26) Almeida, Rherison Tyrone Silva; Griebeler, Nori Paulo; Ribeiro, Noely Vicente; Bayer, Maximiliano; Griebeler, Nori PauloThe elaboration of maps related to urban and environmental planning, such as director plans, zoning agricultural, risk areas, etc., generally follow modeling techniques. For the development of these models are required use of databases and different methods applications. However, a significant portion of available databases do not have adequate quality but, as are the enabling be acquired involuntarily leads the professional to use them. In this sense, aiming to verify the influence of database and methods in modeling underwent the following procedures: i) compare quantitatively the use and land cover between two medium and high spatial resolutions maps; ii) compare quantitatively soil loss areas from six topographic factor scenarios (LS), generated from two digital elevation models (DEM) of medium and high spatial resolution and two methods of flow direction (simple and compound); and iii) compare quantitatively and qualitatively areas of soil loss - especially those who are more vulnerable - from twelve scenarios universal soil loss equation (USLE) modeling. The study areas include João Leite river and Bandeira stream. To compare the maps of land cover were used two orbital images: Landsat-8 OLI 2014 sensor (30 m spatial resolution) and Theos-2011 sensor (2m spatial resolution). These two orbital images originated three land cover mappings: Theos/2011 (not prepared by the author), Landsat/2014 and Theos/Atualizado-2014 (generated updating the mapping Theos/2011 from the visual interpretation of high resolution spatial images available on Google Earth software). In relation to USLE, the R factor (erosivity) was obtained from records of 5 rainfall stations; the K factor (erodibility) was obtained by values determined in the literature; were generated two scenarios of CP factor (cover and management and support practice) using the Landsat/2014 and Theos/Atualizado-2014 mappings, which was adopted soil loss values determined in the literature; and to the LS factor (topographic) were generated six scenarios, using the DEM Topodata (~30m spatial resolution) and DEM2006 (~4m spatial resolution); and the direction of methods of D8 flow (single) and D∞(compound), for the two watersheds. When comparing land cover maps Theos/Atualizado-2014 and Landsat/2014, it was found due to the difference in spatial resolution and classification method, Landsat/2014 overestimated vegetation classes and underestimated pasture, agriculture and forestry classes. As for the modeling of topographic factor (LS) was observed that the scenarios composed by DEM Topodata and D8 flow direction method was inefficient at modeling the runoff, and underestimate the most vulnerable classes. The scenarios originated by DEM DEM2006 and D∞ method allowed the best modeling, considering the flow as much as convergent divergent. In relation to soil loss modeling (USLE), different databases and methods employed in the LS and CP factors influenced the identification of most vulnerable areas of the twelve generated scenarios. The scenarios composed by Topodata and D8 method DEM beyond underestimate the risk areas classified as Strong to Very Strong up to 95%, made it possible to identify the exact location of these areas. The scenarios composed by Topodata DEM and D∞ method had a better performance than DEM Topodata and D8 method by allowing the location of the region where the most vulnerable areas were located. However, the setting allowing better detail relief as well as the accuracy of the identification of the most vulnerable areas was composed of the LS factor DEM DEM2006 D∞ and method, and CP Theos factor. It was found that, for the viability of land cover mapping and modeling through USLE in identifying the most vulnerable areas applications of robust methods and high resolution spatial database are required.Item Respostas da variedade CTC-4 de cana-de-açúcar em função de dados agroclimáticos e espectrais em Santo Antônio de Goiás(Universidade Federal de Goiás, 2017-08-29) Quirino, Dayanna Teodoro; Sanches, Ieda Del’Arco; http://lattes.cnpq.br/2456184661855977; Evangelista, Adão Wagner Pego; http://lattes.cnpq.br/5171893735359718; Casaroli, Derblai; http://lattes.cnpq.br/1054839770814863; Casaroli, Derblai; Alves Júnior, José; Barros, Juliana RamalhoSugarcane is one of the crops that has relevance in the Brazilian economy due to its diversified utility. Consequently, the availability of accurate information on biometric behavior, crop tolerance and crop productivity can assist in the decision-making of variety roll-out in the region. Information about the climatic conditions of a region associated with mathematical models of agricultural productivity estimation is important for the sugar and alcohol sector, helping to organize the operations in the plants. The objective of this study was to evaluate sugarcane responses to central-western agrometeorological variables as well as to compare four methods to estimate sugarcane productivity in the municipality of Santo Antonio de Goias. The experiment was carried out in the municipality of Santo Antônio de Goiás, whose productive area belongs to the CentroÁlcool S.A. plant. The sugarcane variety CTC-04 was used in a productive area of 193 ha, with cultivation in dry conditions. The evaluations were carried out in the cane-plant and cane-soca cycle (1st and 2nd soca), referring to the harvests of 2013/2014, 2014/2015 and 2015/2016. The biometric variables were: height, diameter, number of green leaves and index of leaf area in relation to time and climatic variables. Evapotranspiration was obtained by the FAO standard Penman-Monteith method, the daily climatological water balance was calculated by the methodology proposed by Thornthwaite and Mather. The estimation of productivity of the sugarcane crop was estimated by four models: Agroecological Zone (ZAE), model proposed by Scarpari, model proposed by Martins and Landell and Spectral Agrometeorological. The precipitation volume in the years of 2014, 2015 and 2016 in the dry and rainy periods registered a volume lower than predicted in the climatological normal. The average air temperature remained within the expected range. The water balance of the crop recorded in crop seasons 13/14, 14/15 and 15/16 an accumulated water deficit of 857.91 mm, 772.38 mm, 599.81 mm respectively. The biometric behavior of sugarcane cultivated in Santo Antônio de Goiás presented an average rate ofstem height and diameter in the crops of 13/14, 14/15 and 15/16 of 0.49 cm day -1, 0.022 mm, 1.14 cm dia-1 0.04 mm and 0.75 cm dia, 0.04 mm respectively. The average number of green leaves was 7 leaves for crops 13/14 and 14/15 and 8 in the 15/16 crop. The CTC-04 variety showed a better productivity index in rainfed cultivation in the cane-plant cycle. Among the models analyzed to estimate the sugarcane yield, Spectral Agrometeorological showed superior capacity in relation to the others to estimate sugarcane productivity. In addition, its implementation is low cost and allows throughout the crop to monitor the average climatic conditions by phenological stage, identifying the potential losses in productivity caused by water deficiency. The model proposed by Scarpari presented a better estimate of sugarcane productivity in the cane-plant cycle. The model proposed by Martins and Landell overestimated the actual productivity of the crop probably because it does not count on a penalization of the occurrence of climate restriction.Item Produtividade de soja in sílico no bioma Cerrado em função do fenômeno El Niño Oscilação Sul(Universidade Federal de Goiás, 2023-02-28) Nicolau Neto, Publius Lentulus Artiaga; Casaroli, Derblai; http://lattes.cnpq.br/1054839770814863; Battisti, Rafael; http://lattes.cnpq.br/9350992609794419; Battisti, Rafael; Heinemann, Alexandre Bryan; Barbosa, Alexandrius de MoraesSoybean complex has stood out in the growth of the Brazilian economy. One factor that has contributed to this success in production is agroclimate risk zoning, which recommend sowing dates and areas for Brazil with lower climate risk. In this context, during the growing season, crop is subject to water stresses and higher oscillations of air temperature, which result in a decrease in yield and grain quality. Climatic events such as El Niño Southern Oscillation (ENSO) cause serious social and economic impacts, and are characterized with events of floods, storms, frosts and prolonged droughts. Crop and environment has a multiple interactions and crop modeling comes as a science based on a simple representation of a system capable of represent these interactions. This way, the aim of this study was to evaluate the effects of the ENOS on simulated soybean yield in different Brazilian regions, sowing dates, maturation groups and soil type. For this, the CSM-CROPGRO-Soybean model was used to simulate yield for 14 locations in Brazil. Climatic data from 1961 to 2016 was obtained from the National Institute of Meteorology and complemented from NASAPOWER until 2020, totaling 60 growing seasons of simulation. The simulation were performed using three soil types and three maturation groups, obtained from works that carried out the calibration of the model. Sowing dates were based on agroclimatic risk zoning, considering the maximum sowing window, divided into each ten days. The yield was correlated with the qualitative classification of ENOS (El Niño, La Niña and neutral phase). El Niño and La Niña phase occurred in 35% of growing season each, totaling 42 events in 60 years. In Cerrado biome, the majority of municipalities indicating a better performance with a late cycle, considering the greater sowing window. The greatest yield gains were obtained in growing seasons with neutral and La Niña phase, resulting in higher yield when compared to El Niño phase. This way, the sowing dates and crop cycle can help to reduce climate risk, independent of ENOS phase, but with soybean showing higher potential yield in growing seasons under neutral and La Niña.Item Uso de microrganismos multifuncionais na cultura do feijoeiro(Universidade Federal de Goiás, 2021-02-23) Rezende, Cássia Cristina; Filippi, Marta Cristina Corsi de; http://lattes.cnpq.br/0029536556461484; Lanna, Anna Cristina; http://lattes.cnpq.br/0661616367659826; Nascente, Adriano Stephan; http://lattes.cnpq.br/3194091518396388; Nascente, Adriano Stephan; Lacerda, Mabio Chrisley; Moraes, Moemy Gomes deCommon beans are a product with high economic and social importance in Brazil from the food point of view. Currently, the challenge is to reduce the use of pesticides and synthetic fertilizers, seeking more sustainable production with social, environmental and economic gains. In this regard, the use of biotechnological alternatives such as multifunctional microorganisms (MM) are considered an option for improving agricultural practices. The objective of this research was to determine the effect of the use of multifunctional microorganisms, isolated or in mixture, in gas exchange, production of shoots, root and total biomass, accumulation of nutrients in the shoots, roots and grains, components of grain production and productivity in common bean culture. Two experiments were carried out under controlled conditions (greenhouse), in the first and second half of 2019. In both experiments, the experimental design was completely randomized, with 26 treatments and three replications. The treatments consisted of the application of MM and their combinations in pairs, with nine rhizobacteria isolated BRM 32109, BRM 32110 and 1301 (Bacillus sp.), BRM 32111 and BRM 32112 (Pseudomonas sp.), BRM 32113 (Burkholderia sp.), BRM 32114 (Serratia sp.), 1381 (Azospirillum sp.) And Ab-V5 (Azospirillum brasilense), a T-26 edaphic fungal isolate (Trichoderma koningiopsis) and a control (without MM). These MM were applied in three moments: microbiolization of the seeds, watering of the soil seven days after sowing (DAS) and spraying of the plants 21 DAS. The difference between the experiments was the common bean cultivar used, BRS Uai in the first and BRS FC 402 in the second. Based on the results, it can be inferred that some of the tested microorganisms, applied alone or in combination, provided significant increases in gas exchange, production of shoot, root and total biomass, accumulation of nutrients and grain yield in the common bean crop. In the first experiment, isolates 1301 and T-26, in addition to the combinations Ab-V5 + T-26, BRM 32114 + BRM 32110 and 1381 + T-26 provided better results, since they allowed a 36.5% increase in grain production , higher biomass accumulation (78.0%) and higher N, P and K content (42.6; 67.8 and 25.7%, respectively) in the shoot of common beans. In the second experiment, the isolates Ab-V5 and BRM 32112, in addition to the combinations BRM 32114 + T-26, 1301 + BRM 32110 and BRM 32114 + BRM 32110 were the outstanding treatments, providing increases in gas exchange (stomatal conductance - 79, 1% and transpiration - 10.0%), in the content of macronutrients (N - 63.3% and P - 56.7%, in the shoots and P - 42.7%, in the roots) and in the agronomic performance, providing twice the grain yield. Therefore, the results allow to infer that the use of MMs is a good strategy to provide increases in the yield of common bean grains. However, studies must be carried out in the field to confirm the good results obtained under controlled conditions.Item Desempenho agronômico do arroz de terras altas em condições controladas, promovido por microrganismos multifuncionais(Universidade Federal de Goiás, 2020-02-20) Fernandes, João Pedro Tavares; Filippi, Marta Cristina Corsi de; http://lattes.cnpq.br/0029536556461484; Nascente, Adriano Stephan; http://lattes.cnpq.br/3194091518396388; Filippi, Marta Cristina Corsi de; Nascente, Adriano Stephan; Lobo, Valácia Lemes da Silva; Lacerda, Mábio ChrisleyRice is among the three most consumed cereals in the world, it is the staple food for more than 50% of the world population and an important source of carbohydrates.

Aiming at a sustainable production, which provides greater productivity, with the use of less quantity of inputs, it is necessary to improve cultivation techniques, thus meeting the growing demand for food. In this sense, the use of multifunctional microorganisms can be a strategic alternative for this sustainable production. This is because, these microorganisms provide several direct and indirect benefits to plants, such as the production of hormones, siderophores, phosphate solubilizers, improved nutrient absorption and gas exchange and bioprotection against biotic and abiotic stresses, factors that result in greater productivity crop grain. The use of a mix of multifunctional microorganisms can have a greater beneficial effect when compared to the use of these same microorganisms used in isolation. However, there are still few studies on the use of a mix of multifunctional microorganisms in upland rice culture. The objective of this work was to determine the effect of the use of multifunctional microorganisms, isolated or in mix on the performance of upland rice culture. For this, three experiments were conducted, in a completely randomized design, where the variables of biomass production, gas exchange, accumulated nutrient content in the plant, components of production and grain yield, total root length, root diameter, volume were evaluated roots and root dry matter in rice plants. In experiment 1, the treatments consisted of the rhizobacterias Bacillus sp. (BRM 32109, BRM 32110 and 1301), Azospirillum sp. (1381), Azospirillum brasilense (Ab-V5), Pseudomonas fluorescens (BRM 32111), Pseudomonas sp. (BRM 32112), Burkholderia pyrrocinia (BRM 32113), Serratia sp. (BRM 32114) and a pool of Trichoderma asperellum (UFRA. T06 + UFRA. T09 + UFRA. T12 + UFRA. T52), applied alone or in a mix of two, three, four and five microorganisms, totaling 26 treatments. However, the mix of various microorganisms did not provide significant increases in the development of rice plants, due to possible competition between them. Thus, the second experiment was carried out in which the microorganisms were applied alone and combined in pairs, totaling 26 treatments. In the third experiment, the rhizobacteria Pseudomonas fluorescens were tested. (BRM32111), Burkholderia pyrrocinia (BRM 32113), Serratia sp. (BRM32114), Bacillus sp. (1301), Azospirillum brasilense (Ab-V5) and Azospirillum sp. (1381), in the root development of rice seedlings. In all experiments, the control treatment (without microorganisms) was used. Based on the experiments, it appears that the most effective treatments were: Experiment I, microorganisms Ab-V5 + Bacillus sp., Bacillus spp. + Azospirillum sp., Pool of Trichoderma asperellum and Serratia sp. + Trichoderma asperellum pool, which provided the largest increases in the total biomass production of upland rice plants with values of 26.8, 25.4, 23.3 and 21.3%, higher than the control treatment, respectively. Experiment II, the microorganisms 1301 + Ab-V5 and BRM 32114 + Trichoderma asperellum pool, since they provided an average increase of 123 and 88% in the number of panicles and 206 and 167% in the grain yield of rice of highlands, respectively, compared to the control treatment. And in experiment III, the microorganism Azospirillum sp. (1381) provided better performance of the components: root length, root volume and dry root weight in rice seedlings, corresponding to 86.34, 111.53 and 29.41%, respectively superior to the control treatment. Based on the results obtained, it is highlighted that the use of multifunctional microorganisms can significantly improve the performance of the upland rice culture, with emphasis on the good results obtained with the use of the mix in pairs of these microorganisms. However, despite the positive results in controlled conditions, further research is needed, evaluating the possible beneficial effects also in field conditions.
