Summary

Studies are dedicated to prevention of unproductive water losses, reduction of negative phenomena under irrigation on high perme­able soils, increase of wetting uniformity, reduction of irrigation duration under maintaining positive qualities traditionally applied irrigation schemes. Plot relief- undulated surface. According to hydrological aspect - area of limited ground water inflow and outflow with unstable water table and regime depend­ing on local conditions. Ground water salinity 10-20 g/1, salinity type is sulfate-chloride. Soils - silty sandy loam, gray clayer sands, and more seldom loess loam with high gypsum content. EPP area is 1 ha. Irrigation water is supplied from flume canal. Irrigation methods: cotton crop - on furrows, alfalfa - on stripes with cutting shallow furrows. In result of studies recommendations on technological schemes and agricultural crop irrigation technique on high permeable soils were developed.

Key words

Irrigation systems; water losses; irrigation technique; cotton crop; alfalfa
