RESPOSTA DE CULTIVARES DE SOJA A DIFERENTES TRATAMENTOS DE SEMENTES NO LESTE GOIANO

Abstract

The management with efficient products in seed treatment, correlated with the choice of soybean cultivars with a high yield ceiling and adapted to environmental conditions, is an important production strategy. However, information on the correlations of soybean cultivars subjected to different seed treatments, under the conditions of East Goiás, is still incipient. The objective of the present work was to evaluate the hormonal and diazotrophic phenotypic correlation in soybean cultivars. The experimental design used was a randomized block 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 (T1 - Control, T2 - Inoculation, T3 - Hormonal, T4 - Co-inoculation, T5 - Co-inoculation+Hormonal and T6 - 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. It was concluded that the cultivar TMG 1180 has a high yield when its seeds are inoculated with Hormonal seed treatments and with diazotrophic bacteria in Co-inoculation.
