Appendix includes 48 tables and 14 figures. Research Objectives: The study focuses on the processes of forming the productivity and quality of grain crops based on sowing dates. Research Goals: To test and adapt innovative production technologies for winter wheat and winter barley grains of modern varieties to the region's conditions, ensuring their genetic potential for yield and quality. Research Methods and Conditions: Field research with commonly accepted observations, southern chernozem soil, based on the principle of uniform difference. Findings: Sowing dates should be differentiated for varieties with different vernalization periods and photoperiod sensitivity. Over the three years of study, higher yields of winter wheat were obtained on average when sown on October 5 in most studied varieties: - In 2021-2022: Yield averaged 3.60 t/ha. - In 2022-2023: Yield averaged 3.90 t/ha. Higher yields of winter barley were obtained on average when sown on October 5: - In 2021-2023: Yield averaged 3.55 t/ha. - In 2021-2022: Yield averaged 3.60 t/ha. - In 2022-2023: Higher yield (4.10 t/ha) was obtained when sown on October 15. Agrochemical analysis results of winter wheat grains show that over the study years, Class 3 grain was obtained, with the highest protein and gluten content observed when sown on October 15. On average for 2021-2022, the highest protein and the lowest starch content in winter barley grains were recorded when sown on October 15. In 2022-2023, the highest protein and the lowest starch content were accumulated when sown on October 5. Economic efficiency calculations for the cultivation of winter wheat and barley over the three years of study (2021-2023) showed that the highest level of profitability was observed when sown on October 5, reaching 85.7% and 79.3%, respectively.
