Agriculture is a key sector of the economy in the Republic of Kazakhstan. In the arid conditions of the south of Kazakhstan, the problems of the rational use of water resources and the introduction of effective irrigation technologies that ensure stable and high yields of fodder crops and maintain the soil fertility are of particular relevance. A promising technology for optimizing the plant development conditions is finely dispersed sprinkling irrigation, which ensures the optimal water conditions for the soil and plants in a favorable microclimate in the plant development environment. The considered technological methods of cultivating fodder crops, such as maize and sorghum, with the use of supplementary foliar fertilization with the Kristalon product in the amount of 4 kg/ha ensure an increase in the biological yield of the cultivated plants. The triplicate treatment of the plants in the phases of three leaves, beginning of tillering, and stem elongation is recommended for these crops in the conditions of the south of Kazakhstan. Supplementary foliar fertilization of maize and sorghum, compared to the plants without fertilization, increases the green mass yield of the crops by 10 % and more. Increasing the amounts of the product and the number of plant treatments with the product increases the costs of works, given the cost of the product, and insignificantly increases the yield of the product.
