Fighting weeds on an ecological farm is only possible by crop manual or mechanical weeding, therefore. Buckwheat seed growers have a lot of problems with seed cleaning from weed seeds similar in size. The article presents a comparison of the quality of buckwheat seeds grown on farms of ecological and traditional production. The cleanliness and germination of seeds from ecological farms were found to be significantly lower than from traditional farms. The results of cleaning buckwheat seeds (Fagopyrum esculentum) by an electroseparator are presented. It was possible to obtain 60% of seeds corresponding to C1 and C2 category requirements from seeds grown on an ecological farm and rated ill-conditioned due to high contamination and low germination. The increase of ecological seed germination (by 12%) after special cleaning was significant. Seed economic value increased on average by 13% and the seeds germinated practically simultaneously. The use of electro-separator for cleaning conditional seeds allowed obtaining 40% of seeds corresponding to B and 38% to C1 and C2 category requirements. Seed economic value was by 11% higher compared with control seeds. A conveyor type separator with a flannel belt operating in the high voltage field was used for special seed cleaning. The voltage of the electrostatic and corona discharge field was 40 kV.
