In the context of climate change, there is a growing need to study the impact of environmental factors on plant life. This, in turn, will allow the reasonable use of agricultural techniques, to form high-yielding crops, and increase crop productivity. The following variants of tillage and irrigation technologies were included in the research scheme (i) conventional tillage without irrigation; (ii) no-till without irrigation; (iii) no-till with drip irrigation system; (iv) no-till with system of subsoil drip irrigation. Corn yield varied significantly from the studied factors of cultivation technology. The highest productivity of 12.1 t/ha was obtained under no-till with a system of subsurface drip irrigation and 12.0 t/ha under no-till with drip irrigation system. During the statistical processing of the obtained experimental data, no significant difference between the studied variants was found. Carrying out an economic analysis of corn growing in the arid climate of the Southern Steppe of Ukraine testifies to the high efficiency of application of the new tillage and irrigation systems in the cultivation technology. The application of no-till with drip irrigation system allowed to obtain grain with a cost of 3.72 UAH/t, to obtain a profit of 50.13 UAH/ha with a level of production profitability of 112.2%. It should be noted that the use of no-till with system of subsoil drip irrigation led to slightly lower indicators of economic efficiency of corn cultivation, under which the level of production profitability was 109.0%.
