Studies are dedicated to development of universal drip system with simplified designs of distributor and irrigator and micro-inlets operating under low pressure, which is formed at the expense of slope of place, under irrigation water turbidity to 2 g/1 and particles' largeness to 0.5 mm providing uniform water allocation over irrigation area. EPP natural conditions are typical for central and south-east part of Tadjikistan. Relief is cut by slopes. Soils - brown carbonate, semi-loam. EPP irrigated area is 1 ha. Control plot - furrow irrigation. In result of studies low pressure drip network (LPDN) workability was revealed. Water distribution evenness to irrigation devices and droppers, uniform field wetting with minimal financial and other costs, irrigation water saving, and LPDN system reliability were scientifically and practically grounded.

Key words
