The effectiveness of resource-saving techniques for the cultivation of onions during irrigation in the conditions of the Lower Volga

Relevance. The main areas under vegetables, including onions, are located in the south of Russia. Inclusion of vegetables in the list of food safety products with a threshold value of 90% will significantly increase the responsibility of agricultural workers at all levels for the production and sale of vegetable products. The purpose of the research is to justify the feasibility and effectiveness of cultivating promising varieties and hybrids of onions during irrigation in the Lower Volga region to obtain yields of 150 or more t/ha of high-quality products. Methods. For the first time in the area of chestnut soils, comprehensive scientific research was conducted on resource-saving techniques to increase the productivity of a vegetable crop in an extremely arid climate by regulating the physiological and biological processes during drip irrigation, and a system was developed for applying these techniques. Research in the experiment was carried out according to generally accepted methods...
