Abstract

Nowadays, the rising competition for use of water and environmental resources with consequent restrictions on farmers should change the paradigm in terms of irrigation concepts. or rather, in order to attain economical efficiency other than to supply water requirement for the crop. Therefore, taking into consideration the social and economical role of bean activity in Brazil, as well as the risk inherent to crop due to its high sensibility to both deficit and excessive water, the optimization methods regarding to irrigation management have become more interesting and essential. This study intends to present a way to determine the optimal water supply, considering different combinations between desired bean yield and level of risk, bringing as a result a graph with the former associated with the latter, depending on different water depths.
