The influence of elements of cultivation technology on the productivity of winter vetch with winter rye

The research objective was to study the influence of the terms of sowing on the efficiency of winter crops in pure and mixed crops in the conditions of Western Siberia. The research was conducted on experimental field of JSC “Mikhaylovskoye” of Prokopyevsk area of Kemerovo Region (forest-steppe zone of Western Siberia) in 2015-2017. The objects of the researches were winter vetch varieties Fortuna and a winter rye of the variety Tetra short. Field experiments were made according to the technique of statement of field experiment. The options were placed at random in quadruple frequency. The area of the allotments in experiments was 200 sq.m. The arrangement of allotments was systematic. The predecessor of studied cultures was bare fallow. The ratio of the components in mix: winter rye - 60 %, winter vetch - 40 %. The technology of cultivation of winter crops and winter vetch mix with a winter rye was standard for zone conditions. The scheme of making field experiment: 1) sowing on August, 5; 2) sowing on August, 15; 3) sowing on August, 25; 4) sowing on September, 5...
