Two experiments were carried out, one in summer-autumn and the other during spring-summer, Coimbra, Minas Gerais State, order to evaluate effect of different doses nitrogen molybdenum on bean plants. The experimental design was randomized blocks, with four repetitions, a 4 x 2 factorial arrangement, consisting levels (0, 40, 80 120 g ha-1), applied by foliar spraying at 25 days after plant emergence, two sowing (0 20 kg ha-1) surface 50 ha-1). In presence absence planting or surface, increment dose up ha-1 elevates number pods per productivity grains bean. general, increasing also elevate pod mass 100 seeds, but these effects are more dependent surface. level N leaves, content seed SPAD readings less solid; for this reason, they should not be generalized.
