Adubação biológica na cultura do feijoeiro e seus efeitos na produtividade

Abstract

The common bean (Phaseolus vulgaris) composes one of the essential foods at the table of Brazilians, standing out for the cultivation of three harvests per year of this legume and, therefore, it is necessary to minimize costs and increase its productivity. Therefore, this study aimed to evaluate the effect of biological fertilization on common bean productivity under biological fertilization and different doses of chemical fertilization in the Cerrado region. The experiment was conducted with 28 plots with 4 replications each, which were arranged at random in a factorial scheme. The treatments consisted of doses of microgeo® biostimulator associated with doses of soluble mineral fertilizer NPK, being defined: T0 = 0% of biostimulator and 0% of NPK; T1 = 100% biostimulator and 0% NPK; T2 = 0% biostimulator and 100% NPK; T3 = 50% biostimulator and 50% NPK; T4 = 50% biostimulator and 100% NPK; T5 = 100% biostimulator and 100% NPK; T6 = 150% biostimulator and 100% NPK; of NPK; T7 = 200% biostimulator and 100% NPK. Data were submitted to analysis of variance using the System of Analysis of Variance program and means compared by Tukey's test. Based on this analysis, it was concluded that the biostimulator corroborated the increase in bean productivity, when compared to the control. Therefore, the use of 50% of the biostimulator dose and 100% of NPK is suggested. New studies should be carried out on the subject.
