Investigating the use of drip irrigation systems under different water and soil conditions

One of the techniques for optimal use of water resources is the use of modern irrigation methods with proper design and implementation. The evaluation of irrigation systems determines their strengths and weaknesses. The purpose of this research is to evaluate drip irrigation systems in Iran. For this purpose, four drip irrigation systems were evaluated under different soil and water quality conditions based on the parameters of uniformity of water distribution, irrigation efficiency and uniformity of pressure distribution in the pipes. The results showed that the basic problems in drip irrigation systems were: the inappropriate number and type of drippers, the amount of pressure and its non-uniform distribution, low wetted surface, inappropriate depth of irrigation water and the low level of skill and knowledge of users.
