Diferentes arranjos espaciais influenciando na produtividade da cultura da soja

Abstract

This work evaluated the variety 8473 RSF - DESAFIO in different spatial arrangements influencing soybean yield, with that we analyzed the following variables, being plant height, number of nodes, number of pods, number of grains per pod and finally productivity. The evaluations made in the experiment were to collect 20 plants per plot of the 4 plots present in a treatment, using the completely randomized design (DIC) to generate the statistical analysis. Among the treatments, Treatment A of 20.68 plants per meter had a higher plant height, but in the number of nodes and pods it did not show such development but stood out in productivity, Treatment B of 18.8 plants per meter showed height similar to Treatment C, but the number of nodes and pods was equal to treatment A, Treatment C of 16.92 plants per meter was also equal to Treatment A in relation to the number of pods, plant height and number of plants. nodes and finally Treatment D of 15.04 plants per meter showed a higher number of pods and nodes, but in relation to plant height it did not develop well because it grew laterally and its productivity was lower than the more dense treatment. The variety was quite responsive to different population densities.
