Justification of elements of rice cultivation technology

The purpose of the research is to identify the impact of sprinkler irrigation in rice crop rotation on rice productivity and soil fertility of irrigated lands of the Krasnodar region. To achieve this goal, the tasks of studying the density of weed seedlings after sprinkler irrigation, the content of water-soluble salts and humus in the soil of rice fields, and the reaction of an intensive variety of rice cultivated after irrigation and drainage techniques in rice fields were completed. Material and methods. Field studies were carried out on the Kuban irrigation system of the Krasnodar territory, which is the most typical in terms of soil conditions for the western climatic zone of the region, with various variants for sprinkler irrigation after major planning of basins. An intensive of Rapan rice variety was used. The methods of the Federal Research Center for Rice, the Kuban State Agrarian University, and Russian standards were applied. Conclusions, the obtained results of the conducted studies prove the effectiveness of sprinkler irrigation in rice crop rotation, increase soil fertility, rice productivity, and contribute to the production of environmentally friendly products without herbicides treatment
