Desempenho produtivo de quatro cultivares de soja

Abstract

The objective of this work was to evaluate the productivity and morphological attributes of four soybean cultivars (Glycine max (L.) MERRILL), based on the agronomic concepts, aiming at helping to select a cultivar that has a better performance / performance in the region. The work was conducted at Fazenda Aroeira, located in the city of Dourados, state of Mato Grosso do Sul, in the agricultural year of 2016/2017, with four cultivars of indeterminate growth habit: Monsoy 6410 IPRO, BMX Ponta IPRO, BMX RR Power, BMX Valente RR. The experimental design was a randomized complete block (DBC), with four treatments and five replications, totaling 20 experimental units. The characteristics of plant height, height of insertion of the first pod, number of productive branches, number of pods per plant, mass of one thousand grains and grain yield were evaluated. The data collected were submitted to analysis of variance and the means were compared by Tukey test at the 5% probability level. The cultivar Monsoy 6410 IPRO presented the weight of a thousand lower grains, but was one of the most productive, along with the cultivar BMX Ponta IPRO. The cultivar BMX Valente RR presented a good height of insertion of first pod, but it did not satisfy for the production components, which resulted in a significant difference in production.
