Abstract

To increase the productivity of soybeans and reducing its costs, the use of micronutrients has been intensified in recent years. The objective is to evaluate productivity and yield components of soybeans, with the application of chemical fertilizer formulated with different sources of Zn and trademarks, as well the economic analysis of two application doses. The experimental design was a randomized block design (RBD) with three replications and a factorial 5x2. Consisting of the five fertilizer sources (4 with and 1 without Zn), and two fertilizer doses (300 and 600 kg ha-1). The fertilizers are formulas of NPK (2 - 20 - 18 and 0.3% Zn when Prezento), applied at the base. The Data were subjected to analysis of variance and means compared by Tukey test at 5% probability. The application of 300 kg ha-1 gave rise, in relation to the use of double dosage in Zn leaf contents, since the double fertilization (600 kg ha-1) gave rise of the parameters and yield components of soybeans, as well the levels of P, K and Zn in the soil as residual effect of fertilizer. The economic analysis demonstrated the viability of using double fertilizer dose.
