Influence of frost-susceptible accompanying plants on dicotyledon weeds density and diversity in winter oilseed rape

Original language description

This contribution reports on experiments aimed at assessing the impact of winter oilseed rape (WOSR) crop diversity, crop variety and control method for cabbage stem flea beetle (CSFB, P. chrysocephala) insect pests on the abundance and density of weeds and the plant density of WOSR crops plants in at the beginning of spring. A small plot experiment, designed as a 3-factorial with plots size xx × yy m was sown on August 28, 2023. In crop diversity treatments, WOSR was accompanied by PMCLS, sowing was divided into two steps: PMCLS was sown first and deeper (6 cm) than WOSR which was sown immediately after at a depth of 2 cm. The seeding rate was the same for all nine varieties in all three types of crops (50 seeds/m2). The seeding rate for both PMCLS was 50 kg/ha. PMCLS 1 comprised 56 % of pea, 28 % of lupin, 15 % of buckwheat, and 1 % of lacy phacelia. PMCLS 2 comprised 36 % of lacy phacelia, 28 % of pea, 28 % of buckwheat and 8 % of lupin.
