Complex machines for the production of onions on resource-saving technologies

Relevance. The most common and most mastered method of growing onions, used in the middle zone of the Russian Federation, as well as in the northern part of European countries, is the cultivation of turnip onions from onion. It is believed that this method provides 75% of the production of the entire onion harvest. Due to the sharp increase in the prices of energy carriers, fertilizers, pesticides and agricultural machinery, the production of sharp varieties of onions, grown in the crop, has become unprofitable, and marketable products have lost competitiveness due to high costs. Significant changes in the reduction of labor costs can be achieved by improving the technology and technical means for the production of onions, creating conditions for their work. The effectiveness of designs for sowing seeds of onions, onion sets and planting onions-uterus is determined by the uniform distribution of the bulbs by area of nutrition, depth and their embedding. Results. The material presented in the work is devoted to the analysis of designs and some results of studies of a complex of machines for the production of onions developed in the Penza GAU.
