Supplementation with bioproducts (BP) can be an efficient alternative for the crop management, especially in those that are managed with low applications of mineral fertilizers. The objective of this study was to evaluate the complementary application of the bioproducts ME-50 and FitoMas-E (FE) in the increase of the common bean productivity. An experiment was carried out under field conditions with the common bean cultivar Bat-304. Treatments were distributed in a randomized block design, in a factorial scheme (2 × 2). Two levels of mineral fertilization (0 and 50 kg ha-1) and the application of the bioproducts ME-50 (100 mL L-1) and FE (2 L ha-1), with five repetitions were studied. At 40 days after the emergence, the average of trifoliate leaves per plant was determined and in the harvest the number of pods per plant, grains per plant, grains per pod, mass of 100 grains (g) and yield (kg ha-1) were evaluated. The results showed that application of the ME-50 and FE bioproducts increased the morphophysiological and productive parameters of the bean, with the consequent increase in yield in the presence of mineral fertilization. The results indicated that the ME-50 bioproduct was superior to the FE in both culture conditions. This study suggests that the use of both bioproducts constitutes an important contribution to the productive management of the species which improved the productive component and consequently the yield.
