Effects of various poppy seed pre-sowing treatments on the dynamics of field emergence, structure of yield parameters, oil content and yield of seed

The effects of various pre-sowing treatments poppy seed (chemical product Cruiser OSR, stimulation products TS Osivo and Enviseed, physical treatment by E-ventus method, biological Polyversum Gliorex) on dynamics field emergence, yield, structure yield parameters were evaluated in two cultivars grown three-year trials. Seed with Enviseed led to a significant increase emergence compared the untreated control was same level as OSR-treated variant. In variants treated Polyversum, Gliorex, E-ventus, number emerged plants noticeably lower. stand density key factor achieving satisfactory given that other (number capsules per plant, weight capsule, thousand weight), differences between lower often insignificant. average ranged from 0.85 t/ha (Polyversum) 1.39 (Cruiser OSR), stimulant also proved be effective (TS 1.23 1.16 t/ha). Variants did not differ significantly (0.88 t/ha) yield. All strongly affected year (weather conditions).
