THE TECHNOLOGY OF GROWING CULTURES OF BARLEY UNDER THE CONDITIONS OF THE ARAL SEA REGION OF KAZAKHSTAN

Under the conditions of Kazakhstan Aral sea on the saline soils of the rice rotation at irrigation it is possible to obtain yields of barley at the level of 2.5-3.5 cwtt/ha. The highest yield (3.5 cwt/ha) average for three years of research was obtained in barley with the mode of irrigation of 90 % of the smallest capacity and the dose of mineral fertilizers amounted to N90Р90 + N30 + N30. Fertilizing by dose introduction N90Р90 kg/ha before sowing and conducting feeding (N30) at the beginning of tillering stimulates the formation of shoots, the increase in the number of productive stems and the formation of a high grain yield.
