Tillage systems have significant impact not only on soil properties, but also on general productivity of cultivated crops and, consequently, on the economic efficiency of agriculture. This study's primary goal was to assess the effects of various tillage techniques used in short-grain crop rotation“grain corn – winter rapeseed – winter wheat – soybeans”, on the resulting yields and profitability of crop production. The study was conducted at the Institute of Climate-Smart Agricultureon the irrigated trial fields in Ukraine between 2021 and 2023. Tillage systems, embraced in the study, were represented by differentiated moldboard plowing, differentiated chiseling and differentiated disking with soil slitting. Crop yields were accounted after harvesting at technical ripeness of grain. Economic efficiency was assessed by calculating the figures of gross product value, expenditures, profits, production costs, profitability and recompensating terms. As a result, it was established that the best economic output is provided by differentiated disking with soil slitting, where general profitability reached 73.5% owing to the highest average yields of the crops studied and general yields of grain (7.66 t/ha) and forage (8.31 t/ha) units. The shortest recompensating term of 1.4years was also recorded for the disc tillage system.
