Abstract

Drip irrigation methods in terms of the potential for a solution ideally suited for use in high efficiency distribution of water resources are optimized. If the system is running, regardless of the quality of some of them tride to be not be able to provide benefits to its nominal. In order to understand the strngths and weaknesses of system is required factors in their assessment of the size of. Farm monitoring system included parameters of water quality, soil quality, texture, and uniformity of emitters clogging water distribution, instsllation depth, distance from each other , and the trunk was emitters. The results show acceptable uniformity coefficient and coefficient of variation of discharge rates at discharge were classified as unacceptable. According to the results obtained from the coefficient of variation of flow parameters (Vqs), statistical uniformity coefficient (Us), The coefficient of variation of the dropper(Vpf) in the system of 25,74,22 Percent were calculated, showing system pressure fluctuations is unauthorized. It is concluded that a lack of uniformity at low pressure, poor design, system pressure fluctuations is unauthorized
