Abstract
The current paper has presented the study results on the effect of sowing dates and seeding rates on productivity of wintering peas. Field trials were carried out during 2019–2021. The objects of research were the wintering pea variety ‘Fokus’, ‘Faeton’ and ‘Zimus’. The purpose of the study was to estimate the effect of sowing dates and seeding rates on productivity of wintering peas in the conditions of the southern part of the Rostov region. Sowing dates and seeding rates have influenced the elements of the yield structure and grain productivity of wintering peas. The weight of seeds per plant of the variety ‘Fokus’ ranged from 2.53 to 4.02 g; for the variety ‘Faeton’ it was 2.31–2.67 g, and 2.62–4.49 g for the variety ‘Zimus’. 1000-seed weight was in the range of 125.6–154.1 g for the variety ‘Fokus’, 130.1–157.6 g for the variety ‘Faeton’, 146.2–155.9 g for the variety ‘Zimus’. The maximum productivity of the variety ‘Fokus’ was established at a seeding rate of 1.4 million germ. seeds per ha, in the second and third terms of sowing it was 2.24 and 2.23 t/ha, respectively. In the first sowing period, the maximum productivity was established at a seeding rate of 1.8 million germ. seeds per ha. In the first sowing period the variety ‘Faeton’ demonstrated the maximum productivity (1.97 t/ha) at a seeding rate of 1.2 million germ. seeds per ha; in the second sowing period the yield was 1.93 t/haat a seeding rate of 1.4 million germ. seeds per ha; in the third sowing period the largest productivity (1.81 t/ha) was established at a seeding rate of 1.2 million germ. seeds per ha. The variety ‘Zimus’ gave the maximum productivity of 1.86 t/ha at a seeding rate of 1.4 million germ. seeds per ha in the first sowing period, 2.18 t/ha in the second sowing period, 1.96 t/ha in the third sowing period.
