On the Issue of the Introduction of Water-Saving Technologies for Rice Irrigation in Conditions of Water Scarcity

The article considers the conducted field studies on the introduction of water-saving irrigation technologies in rice cultivation based on the technology of rain and drip irrigation of rice varieties "Gulistan" and "Azure" in experimental field sites of the Republic of Karakalpakstan and Khorezm region of the Republic of Uzbekistan. During the research, the traditional method of suppressing rice irrigation was used as a control option, as well as by drip and rain irrigation, the experimental system was carried out in 5 variants: Option 1 is a control option, that is, suppression of irrigation in the traditional way, option 2 is drip irrigation (watering every other day), option 3 is rain irrigation (watering every other day), option 4-drip irrigation (watering every other day), option 5-rain irrigation (watering every other day), the results of the experiment are shown, a comparative analysis of water costs for growing 1 hundredweight of rice.
