“…However, there is no local production of such machines, while many different pneumatic seeders are produced abroad. They provide accurate seeds sowing at a given depth in a row method [5][6][7][8][9][10][11][12]. But foreign samples are complex in design, and are not adapted to Uzbekistan soil and climatic conditions, and cannot provide even seed placement on the ridges.…”

. For sowing small seeds of vegetables, in particular onions, special seeders are used. They are not produced in the Republic of Uzbekistan, while many diff erent pneumatic seeders are produced abroad. The authors note that foreign samples are complex in design, not adapted to local soil and climatic conditions, cannot provide even seed placement on ridges, and the cost of the seeders themselves and service are very high.(Research purpose) To develop a vegetable seeder in relation to the soil and climatic conditions of Uzbekistan, to determine the seeding rate of onion seeds depending on the length of the active part of the seed reel, to evaluate the formation quality of sowing ridges and irrigation furrows.(Materials and methods) The authors determined the sowing rate by turning the seeder drive wheel at a given length of the active part of the sowing reel and collecting the sown seeds in cups with further weighing. The quality of sowing ridges and irrigation furrows formation was evaluated by the method of profi ling the fi eld before and after the seeder’s pass.(Results and discussion) The authors developed a vegetable seeder that performed three operations in one pass: cutting irrigation furrows, forming sowing ridges of a trapezoidal shape and sowing onion seeds and other small-seeded vegetable crops in a three-row tape method in each tape. They found that the dependence of the seeding rate on the length of the active part of the reel had a slightly fragile parabolic shape, and the required seeding rates – 24-48 pieces per linear meter (3.9-7.8 kilograms per hectare) – were provided with the length of the sowing reel 3.3- 6.2 millimeters. It was proved that the seeder provided a high-quality formation of sowing ridges and irrigation furrows: the row spacing was 68.8 centimeters (installation spacing – 70 centimeters), the top ridge width was 42.5 centimeters (the predetermined one was 40 centimeters), the depth of irrigation furrows was on average 9.6 centimeters.(Conclusions) A vegetable seeder was developed for sowing small-seeded vegetable crops with the simultaneous formation of sowing ridges and cutting irrigation furrows, which ensured high-quality performance of all operations and observance of onion seeds.

“…Uniform seed spacing in the field creates favourable conditions for plant growth by improving the use of solar energy by the plants, promoting root development, enhancing water and nutrient uptake efficiency, and, above all, minimizing intraspecific competition. The resulting plants are not only taller, but they are also characterized by higher and more uniform yields (Fritzsch, 1983;Estler, 1985;Frederick and Marshall, 1985;Joseph et al, 1985;Ozturk et al, 2006;Valério et al, 2013;Ignaciuk and Zarajczyk, 2020).…”

The study evaluated the seeding quality of radish seeds cv. Saxa Polana (percentage of single seeds, double seeds and missed seeds (skips) sown with a Max Pneumatic S 156 seed drill fitted with a pneumatic seed dosing unit set at different forward speeds of a metering unit and different sowing disc speeds. The seeding quality was analysed using Nakagami distribution functions, a chi-squared goodness of fit test, linear regression functions, and the ISO 7256/1, 1984 (E) Standard. The diagrams predicting the effect of the different speeds on the percentage of singles, doubles and skips were highly consistent with the results of the seeding quality analysis based on the ISO 7256/1, 1984 (E) Standard. The authors relied on Nakagami distribution functions to develop a new method for predicting the in-row distance between seeds within the analysed range of speeds, including those which were not empirically tested speeds. The proposed method can be used to predict seeding quality at different speeds when only the selected settings of the dosing unit are taken into account in the analysis. This approach significantly shortens the research time and also decreases the relevant costs.

A universal conical spreader for uniform distribution of granular fertilizers and seeds of grain crops, grasses is proposed. The developed universal conical spreader is designed for subsurface application of above-mentioned granular materials using seed drills and can be used as a passive distributor in a wide variety of applications. The methods of theoretical mechanics and descriptive geometry, particularly the method of replacement of projection plane have been applied to arrive at the design of the cone – the shape of conical spreader. A parametric equation was derived for the truncated part of the cone, which is an ellipse. The unique design of the cone-shaped distributor has a truncating form in the direction transverse to the movement of the seeder. In order to determine the interval of variability of spreader parameters more precisely, an analysis was carried out using a Mathcad-15 software. The results of theoretical research were confirmed in the laboratory and field conditions. The width of seed distribution, uniformity, and stability of distribution were studied to arrive at the most effective cone distributor design. The smallest values of non-uniformity and instability of material distribution of experimental coulter are reached at the values of factors D = 117–119 mm, h = 17–18 mm, and H = 32–35 mm.
