Summary

Purposes of studies are to perfect sprinkling technology by "Kuban" sprinkler as well as irrigation network components, to reduce irrigation water expenses for gift, to increase irrigated lands efficiency, to develop recommendations on sprinkling technology of agricultural and secondary crops, and give recommendations for new EPP design. Climate is continental. Relief is weakly undulated. Soils - middle and heavy loam. Ground water table is 1.1-1.5 m, salinity degree doesn't exceed 0.38-0.39 g/1). EPP area is 61.1 ha (net), land use efficiency 0.97. Water supply - over canal , sprinkler feeding from canal lined with concrete plates. Agricultural crops - cotton, ambary hemp, alfalfa. Control - furrow irrigation. Comparative tests showed: crop yield increase on plot with sprinkling - 1.2 t/ha (27%); water saving - 40%; operational costs reduction

Key words
