Influence of water-saving irrigation technology on the yield of grain crops in the northern region of Kazakhstan

Abstract

The choice of irrigation method depends on the crop, soil, terrain, hydrogeological and climatic conditions, as well as the level of agricultural production development. Sprinkler irrigation has traditionally been used in the northern regions of Kazakhstan due to the natural and climatic conditions of the region and the composition of cultivated crops. The purpose of this research was to study the impact of water-saving irrigation technology on the yield of grain crops in the northern region of Kazakhstan. Experimental studies were conducted in 2022 at an experimental station located in the Akkayin District of the North Kazakhstan region. The main objects of the study were Astana spring wheat, Sabir spring barley, and Dauren spring triticale. It was planned to use a sprinkler irrigation system with a modern sprinkler machine for the irrigation of crops. Control fields without irrigation were used to analyze the effect of irrigation. It was established that the main effect of irrigation can be observed in an elevation in the productive bushiness of crops in irrigated areas, leading to a yield increase. The yield of spring wheat under irrigation was 29.3 c/ha, while did not exceed 24.9 c/ha on a plot without irrigation. The yield of spring barley under irrigation was 46.9 c/ha, whereas was at the level of 34.4 c/ha without irrigation. Spring triticale had a yield of 41.6 c/ha when irrigated, while did not exceed 28.0 c/ha without irrigation. The irrigation effect can be noted as significant based on these results.
