At a comparison with macronutrients, it can maintain that to possess few information on nutritionals aspects referring to micronutrients on beans. This work aims to verify the effect of different rates of manganese and zinc leaf applied on the mineral nutrition cultivated on a “cerrado” soil. A randomized blocks design, with four repetitions, at a factorial outline 5 x 5 was used, involving five rates of Mn (0, 75, 150, 300 and 600 g ha-1) and five rates of Zn (0, 50, 100, 200 and 400 g ha-1) sprayed twice at 25 and 35 days after emergency. It was concluded that the foliar addition of manganese and zinc increased linearly the foliar contents of Mn and Zn. The rates corresponding to maximum technical efficiency of Mn and Zn (315 and 280 g ha-1, respectively) resulted increments the leaf content of N, K, Ca, Mg, S, B, Cu and Fe. Furthermore, there was a marked decrease on P content, under the application of manganese, mainly in the presence of the zinc. Excepting contents of Mn and Zn, there was all the nutrients decreased when used rates higher of maxim technical efficiency of Mn and Zn (315 and 280 g ha-1, respectively).
