Agricultural land plays an important role in ensuring food security and employment in rural areas. For many years, the planned economy has forced Uzbekistan to grow water-intensive crops, which has led to declining land productivity and increased crop yields. In a market economy, new innovative technologies are in high demand not only in agriculture but also in other sectors. In order to solve the above-mentioned problems, our research has found it necessary to set goals and objectives. The purpose of the study was to substantiate the parameters of frontal plowing slope, which provides high-quality execution of the technological process in accordance with the agro-technical requirements with minimum energy consumption without furrow plowing, agrotechnical and energy performance of variable frontal forks. The following results were achieved by performing the tasks identified in the study: a – humidity V=16–17 % and load conditions with elastic rods of 3 mm, 4 mm, 5 mm; b – humidity V=13–14 % and the diameter of elastic rods is 3 mm, 4 mm, 5 mm; c – humidity V=9–10 % and the diameter of the elastic rods is 3 mm, 4 mm, 5 mm. The experiments were performed on lumps with different humidity conditions: 9–10 %, 13–14 % and 16–17 %. The speed of the installation was 1.0 m/s. The recommended technology was to destroy soil fragments with a moisture content of 16–17 % at a vertical load of 400 N with 3, 4 and 5 mm elastic rods at 86.6, 81.5, 75.1 %, respectively, and the vertical load equal to 1,000 N – 94.4, 89.2, 81.2 %, respectively

“…The roller screen is widely used in agricultural harvesting and is especially suitable for seed and grain [68][69][70][71]. Roller screen not only makes use of the impact from screening surface to crushing the soil, but also takes advantage of the gravity to realize centrifugal separation which enhances the cleaning effect [11].…”

Root crops grow in the soil deeply and bond with soil closely, which results in that the process of the separation between soil and root becomes the most difficult during the harvesting processes. In order to harvest root crops efficiently, the mechanical harvesting has become the main developing trend. However, high power and high damage rate are still occurred when mechanical harvester gets in touch with the roots. In this paper, we review the research of the development and evaluation of the mechanical harvesting of root crops and its performance optimization on the past years. The process of soil separation mainly consists in the initial separation between root and the ground and further separation between root and adhered soil. In general, the soil-cutting operation in the initial separation and the sieving mechanism in the further separation require high draught and power. And the dramatic friction, impact, pressure and so on, which happen in the components and soil-roots, are the key reasons to lead to root damage. The optimization of harvesting methods and parameters, including the digging shovel shape, working conditions, vibration, and screening way, is more significant in improving the harvesting performance. But there are still some limitations in the research and application of the mechanical harvester for root crops. Future research is suggested to focus on the development of the soil break-up when the digging shovel cutting soil, the insight into the interaction between soil and roots by different external compression loads, and the long-term studies to verify the high-efficiency and low-damage performances of mechanical harvester in practical application.

“…The main drawback of covering implements of sowing and planting machines is their action on the planting stock in the longitudinal direction which results in piling up of the surface layer of soil and the planting stock itself in the direction of the planter's movement. This, in turn, reduces the uniformity of distribution of bulbs within a furrow and the effectiveness of orientation of bulbs with their stem plate downward by the planter [9][10][11][12].…”

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.
