Use of Organomineral at Fertilization of Beans in the Midwest Region of Brazil

Abstract

This study aimed to evaluate the nutrition and yield of common bean according to the application of different doses of organomineral formulations (OMF), using filter cake as a basic organic compound in the presence and absence of nitrogen. The experiments was implemented and conducted in June "autumn/winter season" and November "rainy season" of the 2018 e 2018/2019 harvest, respectively. A randomized block design was used in a 6 x 2 factorial scheme, with four replications. The treatments were composed of six organomineral formulation doses: (0, 30, 60, 90, 120, and 150 kg ha− 1), with and without the addition of a nitrogen dose of 40 kg ha− 1, using urea as the mineral source. It was concluded that the organomineral fertilizer based on filter cake showed greater absorption of macronutrients N and K, an increase in the 100-grain weight, number of grains per pod, number of pods per plant, and grain yield in comparison with the absence of fertilization or mineral fertilizers, highlighting the doses of 90 and 150 kg ha− 1. The use of OMFs is a viable alternative with great potential for soil fertilization in agricultural production, besides the environmental sustainability generated by their inclusion in the production cycle of common bean.
