Investigations directed at effective organization of irrigations and agricultural works for cotton cultivation on basis of irrigations technique optimal elements setting up, concentrated irrigations realization, irrigation regime and feeding planning according to yield planned, in-farm water use planning and management improvement, increase of fertilizers and other resources use efficiency for cotton cultivation. Plot is located in Gissar valley. Climate is sharply continental.Soils are made of old irrigated light sierozems and brown carbonate, non-saline, heavy, medium and light, slightly stony. Ground waters are at big depth, fresh and slightly mineralized. Plot irrigation is implemented from Great Gissar canal with mineralization less than 0.7 g/l. Plot area is 76 ha (net).Irrigation network is open, efficiency is 0.85-0.90, specific extent is 64 m/ha. As a result of investigations the algorithms are developed for coordination of irrigations, the pivot of which is irrigation schedule of each plot.

For the purpose of initial data collection, processing and storage automation special automatic system "Meliorator" which provided on 18000 ha cotton yield increase 0.2 - 0.4 t/ha, plant growth improvement, 1600 m3/ha irrigation water saving.

Key words
