Abstract
Research carried out in the northern forest-steppe of the Western Siberia on leached chernozem showed that of all the studied dates of sowing bromegrass under the cover of spring crops, the maximum yield was obtained when sowing from 10 to 20 July under the cover of a mixture of oats with rapeseed or winter rye - 8.5 and 7.1 t/ha of dry weight respectively. This is achieved by controlling the weeds before sowing when cultivating the field and creating optimal conditions for the development of forage crops, which affects the safety of young bromegrass plants after wintering 84-97%. The use of Sudan grass as a cover crop when sown between 15 and 25 May results in up to 49% loss of bromegrass from the grass stand, but due to the early harvest of the cover crop, bromegrass has time to accumulate enough spare nutrients for successful overwintering. The average annual yield of dry mass is 5.0 t / ha. Sowing bromegrass from 10 to 20 June under cover mixtures of bromegrass with rapeseed or millet with rapeseed suppresses both the cover crops and the weeds, which have the most favorable growth conditions at this time. After harvesting, bromegrass forms a grass stand with a dry matter yield of 5.8 t/ha.
