| Abstract | Goal. To identify the influence of pre-sowing treatment of winter wheat seeds with biological preparations on its field germination. Methods. Field, laboratory, mathematical and statistical. The results. One of the ways to increase the intensity of seed germination is its pre-sowing preparation, which includes trace elements and growth and development stimulators. On average, over three years of growing season (2018–2020), pre-sowing treatment of seeds with biostimulant Emistim C and microfertilizer Avatar 1 provided a significant increase in germination energy and laboratory germination compared to the control. Significantly higher quality indicators were obtained with the complex treatment of seeds with a biostimulator and microfertilizer – germination energy and laboratory germination increased by 7 % on average over three years, compared to the control. During the pre-sowing treatment of seeds with only one of these drugs, the quality indicators were significantly higher than in the control, but no significant difference was found depending on the application of Emisim C or microfertilizer Avatar 1. The field germination of seeds after its treatment with biological preparations increased by 8.9–14.1 %, compared to the control. Field germination was significantly higher (by 5.1–5.2 %) with the complex treatment of seeds with a biostimulant and microfertilizer than with only one of these drugs. It was found that along with pre-sowing treatment of seeds with biopreparations on field germination, growing conditions had the greatest influence, the share of which influence was 50.3 %, the effect of seed treatment was also large – 46.5 % Conclusions. Pre-sowing treatment of seeds with biostimulant Emistim C and microfertilizer Avatar 1 provided a significant increase in germination energy, laboratory germination and field germination, compared to the control. Significantly higher quality indicators were obtained with the complex treatment of seeds with a biostimulator and microfertilizer – germination energy and laboratory germination increased by 7 % on average over three years, field germination – by 14.1 %, compared to the control. | ||
