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

In the conditions of Aral Sea region in Kazakhstan on the saline soils of the rice rotation it is possible to obtain yields of barley at the level of 2.5?3.5 cwtt / ha by the irrigation. The highest yield (3.5 cwt / ha) average for three years of research was obtained in barley with the mode of irrigation 90 % of the smallest capacity and the dose of mineral fertilizers N90Р90 + N30 + N30. The fertilizing by dose introduction of 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.
