The common bean when grown under conditions appropriate technology, particularly the use of soil tillage systems and nitrogen fertilization, promotes the achievement of high yield; however, has little knowledge on such practical cultural intervening in the technological characteristics of grains. In this way the work had as objective to verify the influence of soil tillage systems (conventional soil tillage and no-tillage) and nitrogen fertilization in topdressing (0, 40, 80, 120 and 160 kg ha-1, source urea) in the yield, agronomic efficiency, technological and nutritional characteristics of common bean, Pérola cultivar. The experimental design was the randomized in split plot design, with four replications. The parcels were represented by soil tillage systems and subparcels by doses of nitrogen topdressing. The yield is influenced positively by nitrogen topdressing, but with greater need of fertilizer in no-tillage system. The agronomic efficiency is higher in conventional soil tillage. The increase of the protein content is in function of increasing doses of N in topdressing in no-tillage and conventional soil tillage. The cooking time decreases in function of employed doses of N in no-tillage in relation to conventional soil tillage. There is increase in the maximum time hydration of beans until the application of 120 kg ha-1 of N in no-tillage and conventional soil tillage systems.
