The studies were carried out in the European part of Russia in the steppe zone. The response of five Zea mays L. hybrids from different maturity groups to the spatial variability of regional conditions (climate, soil quality, agricultural technology) was studied. The obtained data are necessary for scientifically substantiated selection of agro-ameliorative measures and schemes for managing the production processes of agricultural plants in the context of changes in the boundaries of agro-climatic zones under the influence of global warming. It has been established that the limiting factor in the sustainable production of corn grain in areas with insufficient heat supply is the short duration of the growing season, therefore, earlier sowing dates for early ripening and cold-resistant hybrids are necessary. For areas with insufficient moisture supply, the conditions of moisture deficiency in the summer months reduce the yield of corn grain, so it is necessary to combine the early sowing of mid-season hybrids and the methods of moisture-saving technologies.
