The water shortage in most countries has caused farmers to use modern methods instead of traditional irrigation methods, have greater control over water consumption. Among the programs implemented in order to reduce water consumption and increase its productivity in the agricultural sector, is the use of pressurized irrigation method. This study aimed to determine the factors affecting the adoption and development of pressurized irrigation in Ardabil province, the required collected data in the form of questionnaires from farmers for crop year 2015-2016 and using logit regression model. The results indicate that the labor costs of water, literacy, education, income, Second career farmers, cultivation, satisfaction with administrative, expertise and credibility services, have positive effectiveness, and history of agricultural activity, product number, cost of water consumption implementation of irrigation systems, and new irrigation cultivation have negative effect on the acceptance and development of pressurized irrigation cultivation. The average marginal effect factors on the development of pressurized irrigation is 0. 345 The ultimate effect of education, water consumption volume and satisfaction with banking and administrative services on pressurized irrigation development is estimated more than other factors.

Due to increasing demand and supply gap of water and reclamation plan and balance of groundwater resources by the Department of Energy It is expected to reduce water resources , regardless of the agricultural sector , Excessive pressure on the sector in the future through rations and water from reallocation of resources to sectors with higher priority enters this section. In this study, the effects of In this study, the economic effects of nonprice policy reduced water supply on the components of the agricultural sector in the province of Qazvin According to the data of the crop year 93-92 and by developing a positive mathematical programming model is investigated. The results showed that , with the policy of reduce water availability , crop patterns are highly impressed And more driven towards products that make water use more than economic efficiency. With increasing restrictions on water resources, increased economic efficiency water This suggests that the increasing scarcity of water resources and the signal value to agricultural producers To allocate water more economically valuable products in terms of lack of water resources.
