HORMÔNIOS E BACTÉRIAS EM TRATAMENTO DE SEMENTES DE SOJA NO LESTE DE GOIÁS: UMA AVALIAÇÃO EM TERMOS DE RENDIMENTO

Abstract

The management with efficient products in seed treatment, correlated with the choice of soybean cultivars with high yield ceiling and adapted to environmental conditions, is important in planting activities. Since there is a lack of information on the correlations of soybean cultivars subjected to different seed treatments under the conditions of East Goiás, the objective of this work was to evaluate the hormonal and diazotrophic phenotypic correlation in this plant. The study was conducted under a randomized block experimental design, with four replications, in a 3x6 factorial scheme, corresponding to 3 soybean cultivars [Desafio 8473, TMG 1180 and CD 2737] and 6 seed treatments [Control, Inoculation, Hormonal, Co- inoculation, Co-inoculation+Hormonal and Inoculation+Hormonal]. Significant effects were found in the correlations involving soybean cultivars and seed treatment, except for plant height, number of pods with 1 and 4 grains and weight of a thousand grains. Cultivar TMG 1180 showed higher yield when its seeds were inoculated with hormonal seed treatments and with diazotrophic bacteria in co-inoculation.
