With the objective of evaluating the income of the bell pepper fertilized with bovine manure in the presence and absence of the biofertilizer, the experiment was led in the period of January to June of 2004, in NEOSSOLO REGOLÍTICO, typical Psamítico, frank-sand texture, in the Centro de Ciências Agrárias of the Universidade Federal of Paraíba, Areia-PB-Brazil. The experimental design was randomized block, with three replications in outline of sub-divided plots, with the treatments distributed in factorial arrangement (6 x 3) + 1. The plot was constituted by 32 plants and the sub-plot by 16 plants, spaced with 1,00 x 0,50 m. In the plots, were appraised six levels of bovine manure (0, 10, 20, 30, 40 and 50 t ha-1), while in the sub-plots the forms of application of the biofertilizer (absence biofertillizer, through soil and through foliating), besides an additional treatment with mineral and organic manuring. In 45 days the plants height increased in the order of 0,0943 cm to each ton of bovine manure applied, at 65 days, the levels of 30,8 t h-1 of bovine manure, it was responsible for the dear maximum height of the plants, 33,0 cm. The maximum values for medium weight of fruits (143,33 g) and number of commercial fruits for plant (3,0) were obtained in the presence of the biofertilizer in the soil, 50 t h-1 and 30 t h-1 of bovine manure, respectively. For the fruits total production, levels of 20 and 30 t h-1 of manure bovine associates to the applied biofertilizante through foliating and in the soil, provided the largest productions 21,32 and 22,76 t h-1, respectively, overcoming 13,43 and 14,87 t h-1, obtained without manure application and biofertilizer (7,89 t have-1). The maximum values for the production of commercial fruits for plant (256 g) and of commercial fruits (7,8 t h-1), were obtained in level of 28 t h-1 of bovine manure, in the absence of the biofertilizer. The bovine manure and applied biofertilizer combination through foliating, was the best form of organic fertilization in bell pepper, with increments 1,8 and 1,3 t h-1 the production of commercial fruits, in relation to those just obtained with bovine manure and with applied biofertilizer in soil, respectively. For the levels of N, P and K in bell pepper leaves, significant effects were not verified. The pH and P, K levels and organic matter, were increased in relation treatments, and values initially on soil.
