Operative and reasonable use of irrigation water in the environment of the Republic Karakalpakstan

Abstract

The article presents scientific research, including complex water-saving measures when irrigating crops for the conditions of the Republic of Karakalpakstan. On the irrigated territory of the farm, a demonstration site has been created in the complex, where various types of resource-saving technologies for irrigation and leaching of saline lands are tested and implemented. Taking into account the characteristics of this region, various types of irrigation of agricultural crops were tested at the scientific site, including the equipment and technology of furrow irrigation and irrigation with drip irrigation systems. When using various technologies, significant water savings were obtained compared to traditional irrigation, including: - the rate of land leaching was 2700 m3/ha, which is 850 m3/ha lower or 25% lower than the average value of the experimental indicators of previously carried out leaching; - the irrigation rate when using the drip irrigation system was 2793 m3/ha, while saving water resources by 35-44% than the rate with traditional irrigation. Based on the results obtained, recommendations for the introduction of irrigation technologies for the conditions of the Republic of Karakalpakstan were formed.
