Abstract:

Irrigated crop needs to be more efficient using techniques that promote gains in yield with low water consumption. Objective of this research works was to determine the soil water balance on the beans crop (cultivar Carioca precoce) in a no-tillage system (SPD) and conventional system (SC) and water use efficiency through the relationship among the yield and the accumulated evapotranspiration during practically all crops cycle. The experiment was carried on at Agricultural Engineering Faculty of Unicamp. Results showed that beans crop presented on SPD lower values of evapotranspiration during all cycle, being that difference was more accentuated in the flowering phase, propitiating lower quantity of irrigation. The no-tillage system treatment presents higher water use efficiency and yield with lower water consume by plants than conventional system treatments, showing its importance of the mulching in the soil superficies.
