Abstract

Desirable performance of Emitters is the most important factor in increasing the efficiency of Micro irrigation systems. But, the Pressure variations in these systems and the different sensitivity of the Emitters to these changes lead to a non-uniform distribution of water. In this study, Pressure-compensating Emitter (PCOD-4), dripline (PCID-4), variable discharge Emitter (OD-V) and bubbler (B-60) were evaluated based on American Society of Agricultural Engineers standard (ASAE) to find the best Pressure range to achieve the ideal Emitter's performance. The study results show that in the all experiment Pressures, the OD-V dripper performance was not optimal and the uniformity parameters of the PCOD-4 and PCID-4 drippers in the 1 and 1/5 bars and for B-60 Emitter in the 2 and 2/5 bar Pressure were perfect and Their performance at other Pressures was less than expected values. Therefore, it has been suggested that the mentioned Emitters be used in optimal conditions and for other Emitters the best Pressure range should be found in the experimental tests. The design and management of the Micro irrigation systems should be done based on these results.
