RESULTS OF FIELD RESEARCHES OF PELLETED BUCKWHEAT SEEDS WITH ORGANIC FERTILIZERS BASED ON HUMIC ACIDS WITH SUBSTANTIATION OF CONSTRUCTIVE AND TECHNOLOGICAL PARAMETERS OF CENTRIFUGAL PELLETER WITH BLADE REFLECTOR

One can obtain high yields of crops only when seeds with high varietal and sowing qualities are used for sowing. Various methods of presowing processing are used to improve the seed quality. Presowing seed treatment not only improves germination, but also eliminates seeds from pathogens, significantly increases their viability and improves young crops yield. One of the most promising ways of presowing treatment of small and irregular shape seeds is pelleting. This method helps to increase the seeds size and acquire a spherical shape, which greatly simplifies their sowing and allows to accurately observe the seeding rate. The paper presents design of a centrifugal pelleter with blade reflector, the results of studying the process of buckwheat seeds pelleting, and its best design and technological parameters are determined based on those when organic fertilizers based on humic acids were used as material for pelleting. Factors significantly affecting seed pelleting in a centrifugal pelleter with blade reflector were determined, the choice of objective function and criterion for improving the process are substantiated. A dependence describing the process of seed pelleting in a pelleter was obtained as a result of the regression analysis of the obtained results of experimental studies. The obtained results can be used in the field of crop production in agricultural production during presowing treatment of small seed crops and agricultural engineering during development of centrifugal pelleters with blade reflectors.
