This article presents a brief analysis of the state of rice cultivation, the main advantages and disadvantages of seedling rice planting, analyzes the prospects for rice cultivation and mechanization of this process in Uzbekistan. Measures are indicated to fully meet the needs of the population in this product and reduce imports in Uzbekistan by giving special attention to the placement of varieties adapted to soil and climatic conditions with high-quality grain and high yields, the development and implementation of highly efficient resource-saving agricultural technologies in their cultivation. The factors influencing the decline in the efficiency of rice growing for the Central Asian region are analyzed. The purpose of the use of technical means for planting rice in seedlings is substantiated. The technical characteristics are presented a comparative analysis of the technological process, the main design advantages and disadvantages of machines for planting rice is made. Data on the physical and mechanical properties of soils used for rice crops, as well as on the main varieties of rice grown in the region are presented. After analyzing the agro-technical requirements for sowing rice in seedlings, a technical solution that improves the technological process of transplanting machines of the PA-600D-R and RF-455 brands (Korea) is proposed. The results of research on the development of the design of a planting device with optimal parameters and the possibility of using it for planting rice in seedlings for the soil and climatic conditions of Uzbekistan are presented. A mathematical model of the machine is built and its optimal values have been determined. Using special programs such as Compass 3D, 3D Max, MS Word, MS Excel and a number of other programs, 3D and 2D models of parts of the rice planter planting device were prepared. The analysis and results of the studies carried out will allow using the obtained data in improving the design of the planting device. The use of a machine equipped with such devices when sowing rice in seedlings will significantly reduce the consumption of seeds, irrigation water, shorten the growing season, reduce crop weeds and, as a result, increase grain yield.

“…In addition, the feed mechanisms of these planters have the following disadvantages: the need to calibrate the seeds of row crops, high consumption and damage to seeds, as well as low reliability of the process. It should be noted, that the mechanical precision feed mechanisms of existing planters have undergone a number of studies and upgrades, and have almost fully realized their capabilities to ensure high accuracy, reliability and stability of work [8].…”

The article considers the development of machines that improve sowing and increase the quality of technological operations when sowing cotton. The studies have been carried out for three years in the zone of sharply continental climate of the Republic of Uzbekistan on typical gray soils. The factors influencing the decrease in the efficiency of crop production for the Central Asian region are analyzed. The purpose of the use of clustered sowing of cotton with a given number of seeds in the cluster is substantiated. The results of research on the development of a pneumatic feed mechanism with optimal parameters for accurate sowing of bare cotton seeds in a clustered method for the soil and climatic conditions of Uzbekistan are presented. The physical and mechanical properties of bare cotton seeds of industrial grades C-6524 and “Sulton” were studied. An improved design of a pneumatic feed mechanism is proposed, including a sowing disc with suction cells, which are made in the form of a triangle with rounded tops and with a bridge inside. In this case, the bridge has a Y - shaped form, abuts with its ends against the sides of the triangle. At the same time, a technical result is achieved, it consists in creating the best conditions for a rational group arrangement and reliable suction of cotton seeds in the cells of the sowing disk, which improves the accuracy of their group sowing into the cluster and stable formation of maximum accuracy clusters in the furrow. The data on the economic efficiency of the use of a pneumatic planter equipped with exact feed mechanisms with substantiated parameters for sowing bare cotton seeds by the clustered method are presented.

The article analyzes the influence of the shape of the disc slots of the seeder on the suction force of the vacuum.Currently, pneumatic devices for various soil and climatic conditions are accurate with a cellular method of sowing seeds and the development of a seed drill design, in which 3 seeds are sown in each nest, targeted scientific research is being conducted to substantiate the parameters, ensuring its functioning at the level of agrotechnical requirements.In order to study the influence of the shape of the nests of the lander disk on the vacuum suction force, experimental studies were conducted using the lander disk of three different variants. Based on the conducted experiments, the authors drew their conclusions.
