Object of research – processes of formation of productivity and grain quality of cereal crops depending on sowing dates. Objective of research – to develop elements of a climate-oriented biologized technology for growing promising varieties of winter cereal crops under the arid conditions of the Southern Steppe of Ukraine. Methods and conditions of research: field experiment with generally accepted observations, southern chernozem soil, the principle of single difference was maintained. Key findings: Sowing dates should be set differentially for varieties with different vernalization periods and different photoperiodic sensitivity. When winter wheat and winter barley were sown on 05.10, the lowest average water consumption coefficient was observed – 45.0 mm/t and 42.6 mm/t, respectively. Higher yields of winter wheat over the two years of research were obtained when sowing on 5.10 for most of the studied winter wheat varieties: with a sowing date of 05.10, the average yield was 6.06 t/ha, exceeding the yield by 8.6% compared to sowing on 25.09 and by 2.7% compared to sowing on 15.10. When sowing on 05.10 and 15.10, the average yield of six winter barley varieties was 5.95 t/ha and 5.96 t/ha, respectively, which was 7.45% higher than when sowing on 25.09. Results of agrochemical analysis of winter wheat grain show that 4th-class grain was obtained; the highest protein and gluten content was formed when sowing on 25.10. In most varieties, when sown on 25.10, gluten of the 2nd quality group (85–100 units) was formed, i.e., satisfactorily weak. On average for 2024–2025, the highest protein content and the lowest starch content in winter barley grain were recorded when sowing on 25.10. The highest profitability level for winter wheat and winter barley was achieved when sowing on 05.10 – 200.0% and 170.0%, respectively. Product Description popup.authors Svitlana I.
