Experimental research of the quality layer treatment of seeds in agricultural crops by protective and stimulating preparations

Purpose. Improving the efficiency of pesticide use by justifying rational modes operation of the working bodies treater for layer-by-layer treatment of seeds with protective and stimulating preparations. Methods. The researchers used the method of planning experiments and the experimental-calculation method. Results. Conducting laboratory and field researches of a prototype developed experimental sample for layer-by-layer treatment by crop seeds with protective and stimulating preparations, and indicators of the quality by seed treatment are determined depending on the operating modes at the working body. Conclusions. Regression equations are obtained to determine the quality layer-by-layer processing of seeds depending on the seed supply, the working fluid supply and the angular velocity by working body, on the basis of which the range of changes in the rational operating parameters by working bodies is established, which ensures the best quality of seed processing: the angular velocity of the working body is 80–120 rad/s, seed supply – 0.8–1.2 kg/s, supply of working fluid – 6–10 ml/s. Keywords: seeds, layer-by-layer processing, protective-stimulating preparations, working body, modes of operation.
