ECONOMIC ASSESSMENT OF DIFFERENT WATER IRRIGATION STRATEGIES FOR A VERPEACH CULTIVAR (PRUNUS PERSICA L. BATSCH)
The cost accounting of a 1 ha peach orchard has been studied. Three irrigation treatments were considered: i) Control, full irrigation, ii) R75, irrigated at 75% of ETo (reference evapotranspiration) during postharvest, and iii) R50, irrigated at 50% ETo during postharvest. We have compared costs for each treatment and calculated the corresponding rates of economic assessment and water use efficiency. The labour costs are the main peach growing account for about 60 and 63% of current assets. Gross margin/current assets was higher for Control treatment than R75. Both indexes are very close, 23.8 and 20.8%, respectively. In contrast, R50 had a very low rate. The profit margin is higher and similar in Control and R75, with 0.13 and 0.12 kg-1, respectively. The indicator of economic efficiency is very high and virtually unchanged in the Control treatment (0.55 m-3) and the R75 (0.53).
