PRODUTIVIDADE DE DIFERENTES CULTIVARES DE SOJA COM ADUBAÇÃO FOLIAR NA REGIÃO DE VICENTINÓPOLIS-GOIÁS.

Abstract

The soybean crop (Glycine max (L.) Merrill), It has great global economic importance. The growth of the culture is due to major scientific advances in the field in constant association with the productive sector-focused technologies. One of the major breakthroughs was the development of technological packages, creating varieties able to adapt the new frontiers of Brazil in agricultural regions of low latitudes, associated with fertilization that increase the productivity of these cultivars. The objective of this work was to evaluate and identify which cultivar of soya bean (Glycine max) is more productive and has influences of foliar fertilization in Vicentinopolis region – Goiás. The experimental design was of randomized blocks; in factorial scheme 2 x 11, with four repetitions, totaling 88 plots. The factors consisted of foliar fertilization and fertilizer-free leaf and 11 cultivars of soybeans. Evaluated plant Height (cm), height of insertion of the first pod (cm), number of grains per plant, number of grains per pod, number of pods per plant, weight of the grains (g), weight of 100 grains (g) and productivity per hectare (Kg). The test was applied Scott – Knott the level of p>0,05% significance. There were no differences in foliar fertilizer application only in plant height and insert the first pod. The Syn 1163-RR variety was the one that had the highest productivity and had influence of foliar fertilization.
