Water Use for Bean Irrigation on Eutric Cambisol Soils.

This research was conducted with the objective of evaluating the irrigation performance of bean crops in Eutric Cambisol soil conditions. The main parameters related to irrigation scheduling were determined. The water application for the crop and the behavior of climatic variables during the execution of the work were obtained. The results showed that the needs of crop water are satisfied with 14 irrigations, with a total irrigation of 2 517,72 m3 ha-1,which is very similar to that proposed by several authors for crop beans. However, farmers performed 11 irrigations applying a total net irrigation of 4 843, 3 m3 ha-1 consuming 762,4 m3 more of water to produce a ton of bean than the necessary, applying the planning irrigation proposed in this paper. Total net irrigation applied is far superior from obtained by the crop water needs, which brings about low efficiency in water use. [ABSTRACT FROM AUTHOR]
