Hybrid corn OM 112 is characterized by adaptability to different sowing dates and seed planting depths, allowing it to be effectively used in the central part of Belarus. When sown early, when soil temperature during the pre-emergence period does not reach 10 °C, emergence time may vary from 22 to 30 days, whereas at the optimal sowing date, this period shortens to 14–20 days. Increasing planting depth from 2–3 cm to 6–7 cm delays emergence by approximately 3 days, but plants compensate for this with faster growth, reducing the flowering phase difference to just 2 days between different sowing dates. The height of OM 112 corn plants depends significantly on water regime during the period of intensive growth, with differences between years reaching up to 30%. Meanwhile, changing sowing dates by two weeks, 1000-grain weight ranging from 222–357 g, and seed planting depth from 2 to 7 cm affect plant height by no more than 5%. Optimal sowing date and increased planting depth contribute to higher plant height at the end of the vegetation period, positively influencing yield formation. Thus, hybrid OM 112 exhibits good adaptability to variations in agronomic conditions and can develop effectively under various sowing dates and seed planting depths. This makes it a reliable choice for cultivation in central Belarus, ensuring stable development and potential for high corn yields.
