The bean cultivation is spreading increasingly in the state of Mato Grosso because ofthe advance of implementation of irrigation systems. It is a culture that can be produced in three different times, but irrigated farming is what is showing the best productivity results. The purpose with this study was to evaluate the yield and quality (physical, physiological and chemical) of beans subjected to foliar fertilizer with micronutrients. The experimental design was randomized blocks, consisting of six (6) treatments: 5 treatments with different formulation, composed of macro and micronutrients, and one control treatment, in three (3) repetitions. The applications were conducted at different times. The cultivation was in the 3rd harvest coinciding with the dry season, but under center pivot irrigation system. After manual and mechanical threshing harvest, samples of grain were sent to the laboratory for qualitative analysis and crop yield. The physical quality of the grain was quantified by the thousand grain weight, bulk density, true density, mass and grain volume, and size and shape. The physiological quality of the grain was determined by the percentage of germination and accelerated aging. Regarding the chemical composition, it was evaluated the protein content, dry matter and the amount of nitrogen present in the grains. The data were subjected to analysis of variance (F test 5%) and the averages compared by Tukey test at 5% probability. It was found that the physical quality of the grain showed better results when conducted treatments T6 and T5, with compound guarantees of Fert. Mineral (Cu, P2O5, S) and of the associated Fert. Mineral (N, Fe, Mn, Mg, Ca, Si, Zn). The physiological quality was better preserved when performed T4 (Fert Foliar (Bo;. Cu, Mg, Zn, S, N), Complex. Nutritivo (B;. Co, Cu, Mn, Zn, N;. S) + Fert Foliar (Mn, S), Complex. Nutritivo (B, Co, Cu, Mn, Zn, N, S)., Fert. Foliar (N, K2O).). There were no increases in grain protein due tothe treatments.
