Some stress factors (excess temperature and lack of moisture) have a negative effect on the corn yield in the existence of climate change. This article deals with the corn growing by using adaptive technology that increases crop’s tolerance to extreme climate conditions and has a positive effect on crop yield during global warming. In order to reduce the effect of temperature and moisture stress on the corn yield, field experiments were conducted in the conditions of gray-brown soils in Samukh district. The results showed that it is possible to sow corn 10 days earlier rather than usual sowing time and this causes the temperature-sensitive flowering-fertilization stages of the plant to be less exposed to the excessive mid-summer heat and drought. The grain yield of corn ripened 15 days earlier on the raised beds rather than ordinary planting. The highest grain yield (86,1 quintals per ha) was obtained in the raised bed planting method. Straw mulching of the corn inter-rows saves water in the soil by preventing surface evaporation.
