    Macassar bean is a crop of great socioeconomic importance for farmers in the North and Northeast, where it stands out for its rusticity and adaptation to edaphoclimatic conditions. In its nutritional management aimed at raising productivity, mineral fertilizers of high solubility are used that cause environmental problems such as acidification of the soil and contamination of water courses. The use of organic fertilizers as a source of nutrients, allows to meet the nutritional requirements of plants in a slow and lasting, and use residues that released into the environment would cause strong impacts to it. The objective of this work was to evaluate the effect of the application of the dairy effluent, biofertilizer and inoculant on macassar bean yield. The experiment was installed and conducted at the Experimental Farm of the Federal Rural University of Pernambuco / Garanhuns Academic Unit (UFRPE / UAG). The experimental design was a randomized block design, consisting of nine treatments and three replicates. The treatments were: - T - Absolute Witness; EF - Dairy Effluent; B - Biofertilizer; I - Inoculant; EFI - Dairy Effluent + Inoculant; BI - Biofertilizer + Inoculant; EFB - Dairy Effluent + Biofertilizer; EFBI - Dairy Effluent + Biofertilizer + Inoculant; AM - Mineral Fertilization. The following variables were evaluated: leaf number per plant (NFP), stem diameter (DC), chlorophyll (CLOR), biological yield (RB), dry matter (DM), productivity (PROD), length of pod (CV). The data were submitted to analysis of variance and the means of treatment analyzed by the Dunnett test. Macassar bean yield was higher using mineral fertilizer, organic fertilizers did not favor the increase in macassar bean production.
