Development and yield of common bean in response to organomineral fertilization based on filter cake

This study aimed to evaluate the development 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 of the 2018 and 2018/2019 harvests. 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 morphological traits of the common bean are influenced by the fertilization with organomineral fertilizer combined with the supply of N. 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 dose of 120 kg ha(-1) which made it possible to obtain higher grain yields. 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.
