Abstract. Development of sprinkler irrigation in order to increase irrigation efficiency is in the agenda of agriculture policymakers’ section. In most areas, reduced water quality by reducing the quantity of water is encountered. Consequently, in such circumstances that sprinkler irrigation by poor quality water is done on farms, due to the dissolved ions absorption by leaves results in plant toxicity and leaf-burning, which ultimately leads to reduced crop performance. On the other hand, in conditions of evaporation, high temperature and wind, sprinkler irrigation will have an adverse effect on crop performance. However, experience in Qom province has shown that even in adverse conditions, sprinkler irrigation can be done. As the study area in this research is considered in hot and dry part of country and also located in a desert area, its water consists of very high sodium and chlorine levels and the quality is poor as well. However, due to nightly sprinkler irrigation that has been done several years on this farm, optimal performance of crops is achieved. In this study, we examined the factors affecting this action in order to disseminate this method of sprinkler irrigation and use of saline water, an effective step has done to overcome the limitations of the world's water resources.
