Abstract From 2017 to 2020, research was conducted in the Volgograd region in order to improve the efficiency of water and mineral nutrition management of onions by justifying the calculated layer of soil moisture and agrotechnical methods of cultivation on light chestnut soils to obtain 110 t/ha of marketable products. The main objectives of the research include the rationale for the formation of the water regime of the soil and drip irrigation regimes depending on the wetted soil, the study of patterns of growth, development and yield formation of onion depending on the studied factors, economic and environmental assessment of drip irrigation technology, the quality of the bulbs, depending on the studied factors. The field experience included the following options: water regime of the soil (factor A), mineral nutrition regime (factor B), promising onion hybrids (factor C).The studies were carried out on onion crops C1 – Migros F1; C2 – Dragon F1 ; C3 - Dammica F1. Against the background of the introduction of N 180 P 80 K 70 , the Migros F1 hybrid provides an average of 94.3 t/ha of onions in 3 years of research, which is 16.6 t/ha more in comparison with the Dragon F1 onion; and 2.2 t/ha more in the Dammica F1 hybrid.
