The level of potato production in the developed countries of the world is characterized by the stability of yields reaching up to 45 and more tons per hectare. High potato production in developed foreign countries is achieved through a systematic approach at all stages and technological operations of cultivating and harvesting using advanced technologies and modern technical means. At the same time, in our country, the gross harvest of potatoes from 78.8 thousand ha is 1.717 million tons, that is, the yield per hectare is 21.8 tons. This significant difference in potato yields between domestic and foreign producers is due to several reasons: - in our country, about 90 % of potatoes are produced mainly on small-contour and scattered plots with an area of 0.2-1.5 hectares of dekhkans and farms. In such areas, the simplest technologies with a low level of mechanization are used; - low level of provision of potato producers with high-quality seed materials, as well as low-quality planting calibration of tubers in size, which has a significant impact on the quality of work of potato planting machines; - the lack of domestic potato planting machines differing in the quality of the uniform distribution of tubers during planting, since the quality of the machine depends on this factor; To successfully solve these and other problems of increasing potato productivity, it is necessary to solve the accuracy of dosing potato tubers and their uniform distribution during planting.
