The research aimed to improve the technology of corn cultivation in intensive farming to increase the yield and quality of the crop. Therefore, this study was conducted in 2018-2020 at a large agricultural enterprise Plemzavod Irmen, located in the village of Verkh-Irmen in the Ordynsky district of the Novosibirsk region (Russia) to investigate the main indicators of the condition of leached chernozem of the forest-steppe in the Novosibirsk Ob region (field moisture, humus content, and pH of soil solution) under maize crops grown for silage and grain. The results of the effect of irrigation on the yield are reflected: Kubansky 101 by 53.8% and Katerina by 33.2%, and the photosynthetic parameters of corn by 19.6% and 18.3%, respectively. A high quality, and increased nutritional and feed value of maize grain with a high content of fat (5.1-5.7%), protein (10.3-12.5%), starch (59.4-61.4%), and sugars (3.0-3.5%). The effectiveness of the use of irrigation in the cultivation of corn was established.
