- Abstract
The current water scenario of the country restricts the use of available water resources for irrigation, in order to meet the public supply, therefore, it was aimed to evaluate the effect of water deficit on growth and yield variables of common bean grown on soil of medium and clayey texture. Two experiments were developed in factorial scheme of 2 x 4 with tension for the determination of field capacity on two levels and soil water deficit on four levels in a completely randomized design with three replicates for each soil. Growth analyzes were performed at the grain filling stage of the common bean and the data were submitted to an analysis of variance (p ≤ 0.05). When significant results, the F Test (p ≤ 0,05) was used for the tension factor and regression analysis for the water deficit factor. In the grain filling stage of common bean, soil water deficit levels of 40 and 60% of available water exert negative effects on the growth and yield variables of crop grown on soils of medium and clayey texture, independent of voltage adopted in determining the field capacity.
