The research was carried out to evaluate the performance of drip and sprinkler irrigation products manufactured by different companies viz. Company A, Company B and Company C. Two NPC emitters of 4 lph and 8 lph were tested at operating pressure ranging from 0.5 to1.25 kg/cm2 and one PC emitter of 4 lph discharge was tested at same operating pressure range. Also, sprinkler of 120 lph discharge was tested at operating pressure ranging from 0.75 to 1.5 kg/cm2. The Emission Uniformity (EU) and Coefficient of Uniformity (CU) of system were worked out. In 4 lph and 8 lph NPC drippers manufactured by Company A, discharge variation with respect to pressure was less as compare to standard discharge values of Company B and Company C. In 4 lph PC drippers manufactured by Company B, discharge variation with respect to pressure was very less as compared to standard discharge values of Company A and Company C. It was observed that with increase in pressure from 0.75 kg/cm2 to 1.50 kg/cm2, discharge increased from 57.93 lph to 118 lph for sprinkler manufactured by Company A and from 44.2 lph to 113 lph for sprinkler manufactured by Company B. The highest UC of 90.13 % was found at 1.5 kg/cm2 for sprinkler manufactured by Company A and 88.80 % for sprinkler manufactured by Company B at same pressure. Sprinkler of 120 lph manufactured by Company A given excellent performance with minimum variation in discharge as compared to that of Company B.
