Respostas do pequizeiro à irrigação e adubação orgânica

Resumo

Among all the native species identified as economically viable for the Brazilian Savana, the souari nut has great potential. However, large-scale monoculture production of this plant in the Brazilian Savana still seems risky and unsustainable due to lack of proper crop management practices. This study aimed to evaluate the growth of souari nuts plants subjected to different irrigation and fertilization strategies. The study was conducted at in Goiânia-GO, Brazil, in an orchard with 120 plants (5x5m), with 22 months of age (Nov/2010). The experiment was a randomized block with split plots, six repetitions and 13 times of plants evaluation (23 to 36 months old). The treatments were described in irrigated and non irrigated, fertilized and not fertilized. We used the microsprinkler system, and the water volume applied, based on the estimated crop evapotranspiration. Two fertilization applications were performed (Nov/2010 and Nov/2011), with: compost, coal and yoorin. Plant growth was assessed monthly, based on the following variables: plant height, main branch length, stem diameter, number of branches, length and number of shoots. The results showed that the treatments did not influence the growth of significantly of souari nut plants, confirming the high adaptation to the conditions of these species in the region.
