Abstract
The current paper has presented the study results of the elements of cultivation technology (sowing time, seeding rate) of wintering peas in the southern part of the Rostov region. Field trials were carried out during two agricultural years in 2019–2020 and 2020–2021. The objects of research were the varieties of wintering peas ‘Fokus’, ‘Faeton’, ‘Zimus’. The purpose of the research was to study the effect of sowing time and seeding rates on field germination and harvesting preservation of wintering peas in the conditions of the southern part of the Rostov region. The soil of the experimental plot was ordinary calcareous heavy loamy chernozem on loess-like loams. The content of humus in the arable layer was 3.36%, pH was 7.0, P2O5 was 24.4; K2O was 360 mg/kg of soil. The sowing time had an impact on field germination. On average, over the years of research, field germination in the 1st period ranged from 27.0 to 93.5 %, in the second from 33.6 to 91.0 %, in the third from 31.5 to 94.5 %. The share of the effect of the sowing time on field germination ranged from 9.4% for the variety ‘Faeton’ to 22.5 % for the variety ‘Fokus’. The harvesting preservation of wintering peas ranged from 93.8 % (‘Zimus’) to 94.8 % (‘Faeton’) in the first sowing period, in the second sowing period it ranged from 95.0 % (‘Faeton’) to 95.5 % (‘Fokus’), in the third, the harvesting preservation ranged from 94.7 % for the variety ‘Fokus’ to 95.6 % for the variety ‘Zimus’. The share of the effect of the sowing time on harvesting preservation ranged from 5.4 % for the variety ‘Zimus’ to 23.4 % for the variety ‘Fokus’. On average, over the years of study, the maximum field germination was observed for the variety ‘Faeton’ (93.5 %) at a seeding rate of 1.0 million germin. seeds/ha. The best preservation was identified for the variety ‘Faeton’ (96.5 %) at a seeding rate of 1.0 million germin. seeds/ha in the second sowing period.
