ABSTRACT The optimization in the use of irrigation is a necessity due to water scarcity and the increasing demand for food. The objective of this study was to evaluate the effect of different irrigation depths on the economic efficiency of lettuce, eggplant, beet and carrot, cultivated in an organic production system. The evaluations were performed based on production functions obtained in field experiments conducted from 2006 to 2011, and survey of prices of products and inputs, determining the irrigation depths corresponding to the maximum gross profit and the maximum water use efficiency. Additionally, the relative yield reduction was evaluated for different percent increments in the economically optimal irrigation depth. It was observed that the crops... |
