Results of application of water-saving technologies in rice farming

Abstract

The article presents the results of field studies on the application of sprinkling and drip irrigation technologies in the cultivation of rice in the soil and climatic conditions of the Republic of Karakalpakstan based on the tasks defined in the Decree of the President of the Republic of Uzbekistan dated February 2, 2021, No. PD-4973 "On measures for the further development of rice growing". This article presents the results of field and laboratory studies on the application of rain and drip irrigation technologies in the cultivation of rice, primary irrigation regimes suitable for the soil and climatic conditions of the research object, the mechanical composition of the soil, salinity levels, salinity of irrigation water and the use of water-saving technologies in the cultivation of rice in experimental versions. The influence of the hydrochemical state of water on the soil and the yield of rice and its quality indicators were determined in the field conditions of the experiment.
