Determining the speed of soil particles during the covering of set onion with a disk-type working element featuring a soil guide

In Russia, the major share of vegetable products is produced during the period of March to August. This is due to the inadequate volumes of vegetables fit for long-term storage, and the use of technologies of early production of vegetable cultures. Apart from the above, vegetable farming is highly dependent on imported seed stock. In view of the above, import phaseout and improvement of competitiveness of vegetable cultures in Russia should focus on the development of technologies of production of storable products, as well as on methods of early harvesting of vegetables (during the period of May to July). With regards to the production of bulb vegetables, this problem may be solved by expanding industrial cultivation of onions from set onions, as well as planting of both seeds and seedlings during the autumn season. In particular, techniques of production of set onion, bulb onion from seedlings, and of blackseed onion have poor scientific and methodological background. This deficiency results in a gap between domestic and international process and engineering aspects. This calls for the development and introduction of machines designed for production of onion from seedlings that would be in line with the modern level of development of farm machinery industry for vegetable production
