Abstract
This study aimed at evaluating the yield of grapes per unit area in two methods of drip irrigation and traditional irrigation using two models of Bisaliah and Logit models and analyzing some of the economic, managerial and environmental factors affecting the adoption of drip irrigation among grape producing farmers in Zabol County of Iran. The required information was obtained using a questionnaire completed from 197 grape farmers in the studied area through a random stratified sampling and library documents. The results from the Bisaliah model showed that the use of drip irrigation had two direct and indirect effects on the increase of grape yield; in case of direct effect, without changes in inputs, the yield per unit area increased by 24.14 percent and indirectly, with a change in inputs, the yield per unit area increased by 4.35 percent. In general, the use of drip irrigation in vineyards caused 28.5 percent change in yield (kg / ha). Also, the results from the Logit model indicated that the variables of farmer’s age, number of family labor and access to water had negative effects on the adoption of drip irrigation. It was also determined that variables such as farm area, level of literacy, farmer's occupation, land slope, farmer's income, type of land use, educational and extension classes, and availability of credits and facilities had positive and significant effects on the adoption of drip irrigation.
