Resumo: | The aim of this study was to evaluate the use of NPK 04-30-16 fertilizer in different doses and manufacture technologies (types of formulations) on agronomic characteristics and leaf nutrient levels of two soybean cultivars The experiment was carried out in Itutinga – MG, using a randomized block design, with 3 replications in a factorial scheme 2 x 2 x 3 + 2, involving: two cultivars (Vencedora and Favorita RR), two fertilizer doses (300 e 400 kg ha-1) and three fertilizer formulations (manufacture technologies) NPK 04-30-16: mixture of granules with 4,8% of Ca + 1,64% of S, mixture of granules with 3,9% of Ca + 0,05% of B + 0,06% of Cu + 0,35% of Fe + 0,13 of Mn; mixture granulated with 4,3% of Ca + 1,2% of S + 0,07% of B + 0,24% of Fe + 0,08% of Mn + 0,27% of Zn, and a control (no fertilizer) for each cultivar. It was found that the cultivar Vencedora had a higher productive capacity in relation to Favorita RR. The fertilizer manufacture technologies (types of formulations) and doses evaluated were effective in increasing productivity and its components, and the leaf levels of N, P, Ca, Cu and Mn.There was no difference between doses and manufacture technologies (types of formulations), with or without micronutrients, on agronomic characteristics of soybean and leaf nutrient levels. |
