Research Object – processes of forming the productivity and quality of grain crops in short-term crop rotations under different primary soil tillage systems. Research Objective – to develop scientific foundations for optimizing and adapting crop rotations, primary soil tillage systems, and effective plant production technologies in the Black Sea steppe region. Method and Research Conditions: field research with widely accepted observations, adhering to the principle of a single difference, southern chernozem soil. Research Results: It was established that over an average of 2 years of research, the lowest weed density was recorded after fallow (66.4 plants/m²). Weed density was 3.6% higher after winter rape, 31.2% higher after a pea-mustard mixture, and 57.1% higher after peas for grain. Almost identical weed infestation results for winter wheat crops were obtained for stubble cultivation (84.1 m²) and no-tillage cultivation (83.1 m²). Over three years, winter vetch produced the highest green biomass yield (25.8 t/ha) compared to other predecessors depending on primary tillage. The best impact on green biomass yield formation (15.4 t/ha) was observed with no-tillage soil cultivation. In all experimental variations, fallow with winter rape (3.58 t/ha) had a comparable effect on winter wheat yield to fallow (3.52 t/ha). Positive effects on yield formation were observed for all winter wheat crops with no-tillage cultivation (3.76 t/ha). Across different primary tillage schemes, grain of the 3rd class was obtained on average over 3 years. The best quality indicators for grain were observed with the no-tillage soil cultivation scheme (12.3% protein; 20.9% gluten). When winter vetch was used as a predecessor with winter rape and no-tillage soil cultivation, the highest level of profitability was achieved – 78.7% and 87.1%, respectively.
