Sowing time of winter crops in the Donbass due to weather and climate changes

The purpose of the current study was to clarify optimal sowing time wheat and winter barley after non-fallow forecrops (spring sunflower) due weather climate changes. trials were carried out during 2018–2022 on ordinary blackearth. experiments, records observations according generally accepted methods. There has been established that at early date (September 10), formed up 5.4 tillering sprouts, from 2.4 6.2 nodal roots, plant height reached 22.1–27.9 cm with a weight 174–223 g/m2, which indicated overgrowth plants. At late (October 20), coefficient plants did not exceed 1.0–1.5, number roots 1.1–2.4, 32–58 g/m2.Barley periods had significant developmental advantages compared wheat. termination autumn vegetation, they an average 1.5–2.0 sprouts 2.5–3.1 above-ground mass 2.0 times larger than In spring, grew developed more intensively. Wheat productivity (10.09 20.09) by 7.5–27.0%. When later, contrary, 7.0–14.8%. for maximum grain yield (4.17–4.32 t/ha) can be is period September 20 October 1, 1 10 (4.37–4.48 t/ha).
