| Sumario: | IAC Carioca Eté cultivar is evaluated with regard to soil and water management and nitrogen split application, during the winter, in Selvíria MS, Brazil. Randomized completely block design, in split-split plot scheme, with subplots in strips, with four replications, was used. Plots consisted of three soil management systems: harrow disk, chisel plough and no-tillage system. Three water levels (L1 = 0.75L2, L2 = water level based in Kcs, recommended by Doorenbos & Kassan (1979) and L3 = 1.25L2), applied through a sprinkler system, constituted the subplots and four nitrogen split application: 0- 75, 25-50, 50-25, and 75-0 kg ha-1 applied at sowing time and side dressing, respectively, formed the subsubplots. Soil management with harrow disk provided highest grain yield when compared to no-tillage system. However, it did not differ from chisel plough treatment. Bean crop failed to show yield reduction, even when crop coefficient 25% lower than recommended to water replace in this specific crop was used. Total nitrogen applied in side dressing provided the highest grain yield. |
