The study aimed to evaluate the characteristics of water consumption and sugar beet yield formation under different irrigation methods and fertilizer applications. The experiments investigated the influence of irrigation techniques and fertilization on crop productivity and water use efficiency. The results showed that sugar beet yield formation largely depends on the applied irrigation method and nutrient management. The highest irrigation water consumption per unit of yield was observed under sprinkler irrigation. At the same time, the efficiency of irrigation and fertilization practices varied depending on the biological characteristics of the cultivated sugar beet hybrids. The obtained results demonstrate the importance of optimizing irrigation technologies and fertilizer application to improve water use efficiency and ensure stable yields of sugar beet under irrigated conditions in the foothill zone of Southern Kazakhstan. https://cjes.guilan.ac.ir/article_9633_9e230f9b3fffa788ba02f05fa2f826b1.pdf
