Insufficient scientific and technical support for the improvement of the irrigation land prevents the competitive production of agricultural products in the amounts required for meeting the needs of the domestic market and forming the export resources for taking a leading position in the foreign markets, and for the effective development of the water sector of the economy and the water management policy. A solution to these problems has been provided by the development and implementation of water-saving technologies in irrigation with the integrated regulation of the ameliorative conditions for irrigated lands, which allows considering the possible risks. The improvement of the irrigation conditions for sugar beet and maize with the use of the water-saving drip irrigation technology together with the agrotechnical measures is an integral part of the science-based technology that allows the full use of the biological potential of the cultivated crops. The article presents the developed science-based drip irrigation technologies for grain maize and sugar beet introduced at the Samgau farm in the Kordai district of the Zhambyl region, as well as the proven technological methods of their cultivation with the use of drip irrigation. The irrigation norms for the cultivated crops have been calculated using the biological method. By maintaining various soil humidity levels in various vegetation periods (plant development phases), and by increasing the irrigation norms by additional drip lines in the variants of the experiment, the biological and actual yields have been assessed.
