PREPARATION OF SOWING SUNFLOWER PROCESSING BY GROWTH REGULATORS AND ITS INFLUENCE ON FORMATION OF WASTES IN THE WEST SEDIMENTARY CONDITIONS
Keywords:
sunflower, plant growth regulators, pre-sowing seed treatment, plant development, yield, quality of productionAbstract
The influence of pre-sowing seed treatment of sunflower hybrid NK Brio with growth regulators "Vermimag" (6-7 l / t); "Vermiodex" (4-5 l / t) on its productivity in the conditions of the Western-forest steppe is highlighted. It was established that pre-sowing treatment of sunflower seeds provided; increasing the energy of its germination by 3;4-6;2%; the laboratory similarity by 2;4-3;6%.The best of these indicators were in variants; where pre-sowing treatment of sunflower seeds was carried out by the plant growth regulator "Vermiodis" - 4-5 l / ton. Pre-sowing seed treatment stimulates its germination; improves the growth and development of plants during vegetation; increases yields and improves grain quality.The highest yield was 3.42 t / ha or 0.36 t / ha more compared with control in the version where prior to pre-seeding of sunflower seeds of hybrid HP BRIO was carried out at the dose of 5 l / ton as the growth regulator "Vermiodis".References
