Abstract

The deployment of soybean under no-tillage in degraded pasture has been a trivial practice, and the efficient and rational use of fertilizers is a decisive to its economic viability factor. The objective was to evaluate the agronomic performance of six cultivars subjected to doses of basic fertilization with NPK and straw grown on Brachiaria decumbens. The experiment was conducted in the experimental area of the State University of Mato Grosso do Sul, Unit Aquidauna. The experimental design was a randomized block design in split plot design with four replications. The plots consisted of six soybean cultivars (NA 5909 RR, M SOY 7908 RR, BMX Magna RR, BRS 245 RR, SYN 3358 RR, BMX Potência RR) and the subplots of five doses of NPK (0, 50, 100, 200 and 400 kg ha-1). Were evaluated plant height, first pod height, number of ramifications per plant, mass of 1000 grains and grain yield. Increased doses of fertilizer caused a linear increase in all variables in all cultivars, being recommended for degraded pastures base fertilization with 400 kg ha-1 of NPK. The varieties BMX Power RR 3358 and RR SYN showed higher mass of 1000 grains and consequently higher grain yield.
