Contamination of crops and productivity of rice in various ways of its aerobic cultivation and irrigation

The article presents the results of research conducted in the conditions of the foothill irrigation zone of the South-east Kazakhstan. The features of grain harvest formation and the degree of contamination of rice crops have been studied, depending on irrigation methods, timing and methods of sowing, and methods of weed control. The research results have shown that in conditions of irrigation in the South-east Kazakhstan, sufficiently high yields of rice can be obtained by aerobic cultivation using fine sprinkling or drip irrigation.  At the same time, effective ways of weed control have been identified, forming a favorable phytosanitary condition of rice crops without traditional irrigation with flooding. The results of studies on the contamination of rice crops with various methods of weed control, irrigation, timing and methods of sowing are presented.
