Published: August 2022

Abstract
Air environment status is the most serious problem in the town of Sterlitamak (Russian Federation). The situation is aggravated by the fact that in the conditions of industrial town exist some unfavorable factors. They contribute to the accumulation of emissions from industrial facilities and transport means in the open air. An integrated approach is required to effectively address air basin pollution. This approach should provide for reliable assessment of the air pollution, as well as the development and creation of the systems for monitoring and managing the quality of air basin of the district, the town and the adjacent territory. The article describes the current state of landscaping in Sterlitamak. A lag in the pace of landscaping from the pace of construction which leads to the unsatisfactory state of atmospheric air is revealed. The issues of formation of full-fledged human habitat, in particular, landscaping of territories, are considered. The methods of the monitoring and structuring green spaces which allow increasing in the level of ecological comfort of the environment of industrial town are substantiated. The measures of improving the state of the atmospheric air, such as introduction of unified system of green spaces, landscaping of the sanitary protection zones (SPZ), increasing the number of green spaces in residential areas and landscaping of the railway transport routes are proposed. It is determined that the designing of landscaping of SPZ should be carried out taking into account the nature of industrial pollution, as well as local climatic and topographic conditions. The plants used for landscaping these areas must be sanitary effective and sufficiently resistant to air and soil pollution by industrial emissions. Recommendations on selection of green spaces that contribute to good aeration of the territory and prevent the penetration of harmful emissions into the residential area are given.

Abstract
The problem of rational tillage has always been relevant. Many indicators of soil fertility and the growth and development of plants depend on its rationality. In the experiments that were carried out in the arid zone of the Central Ciscaucasia, the object of the study was winter wheat, cultivated according to the predecessors of corn for grain. The subject of research is zero and traditional technology of crop cultivation. Soil cultivation was carried out according to the traditional technology - after harvesting the predecessor, the 6x4 PM is disked to a depth of 12-14 cm, then non-moldboard tillage with a PCh-4 chisel tool to a depth of 20-22 cm. As weeds appear, PS-4 is cultivated, sowing is carried out with a Bystritsa. Zero technology includes: spraying crops with herbicides using a John Deere sprayer and sowing with a Gerardi G 24 seeder. As a result, it was found that the cultivation of crops using zero technology contributes to obtaining friendly and timely shoots. The 0-20 cm layer contained 26.1 mm of moisture with zero technology and 10.9 mm with traditional technology, this is especially true in dry years. The water resistance of the soil structure in the no-till option is characterized as excellent, to a greater extent this is due to the accumulation of plant residues. The yield obtained on the zero option is significantly higher in comparison with the traditional technology of winter wheat cultivation.
Yield in the cultivation of cotton by sowing seeds under the pellicle
Authors: Muhammediyeva D T , Khasanov U U 
Published: August 2022

Abstract
Uzbekistan is the northernmost region in the world in terms of cotton production, and there are many weather conditions during the cultivation of cotton. In the first months after sowing, the temperature in the northern and central regions is insufficient for its smooth germination. Therefore, additional temperature is required for early sowing of seeds and cultivation of early cotton. Additional temperature accumulation can be achieved by planting seeds under a transparent polyethylene pellicle. The advantage of this technology is the rapid germination of seeds, obtaining flat seedlings and achieving an early harvest. This allows you to fully harvest the crop using cotton-picking machines and plow the land in the warm days of autumn. In areas where the cotton crop is harvested immediately, the grain yield will be at least 10-15 quintals higher than in the areas planted between rows of cotton, due to the quality preparation of the land in the fall and timely sowing of grain. At the same time, it will be convenient even in areas where autumn grain is not planted, as spring sowing will pave the way for a quality transition in the short term. There is no doubt that the effectiveness of the factors listed above is extremely high.

Parameters of the stabilizer of the poly-V belts of the drive of vertical spindles for stable cotton harvesting performance
Authors: Shoumarova M , Abdillayev T , Yusupov Sh A 
Published: August 2022

Abstract
We have in our previous articles that the unstable cotton-picking performance of the vertical spindle cotton picker is mainly due to the instability of the traction force of the V-belts of the friction drive of the spindles. The main reasons for this result were identified. The main reason for the value of the total pulling force of the V-belts in the friction serial drivee, which is why, due to the resistance forces of the cotton bush, the speed of rotation of the spindle often decreases at the time of extraction of the cotton slice from the sash. Therefore, the authors recommended replacing conventional V-belts with poly V-belts, the small wedges of which are installed on one, i.e. a single basis. Our experiments have shown that with the same tension of external belts, the pulling force of a multi-V belt with five wedges is always much greater than a standard set of three conventional V-belts on a serial drive. Consequently, poly-V belts always ensure the optimum angular velocity of the spindle, preventing the reduction of the completeness of the cotton harvest, which is very important. To do this, it was necessary to find some technical solutions for such a drive to function smoothly, in particular, the installation of a spindle speed stabilizer by the time the spindle reversal process was completed before it hit the external belts. Spindle, i.e. its roller, after it leaves the inner belt, rotates by inertia. The stabilizer has a block with an elastic surface, which, pressing against the spindle roller with a certain pressure, slows it down until it stops before the roller hits the beginning of the external belts, i.e. before the start of its reverse rotation. This article describes the design and effects of the stabilizer for the spindle roller to stop it at the right moment.

Abstract
The article points out that studies conducted by domestic and foreign scientists indicate that progress in the economy cannot be achieved without the transfer of agricultural production on a scientific basis. Thus it shall be noted that the main directions of scientific and operational progress in agriculture are: 1. Introduction of high-performance systems, machines for the integrated mechanization of all technological processes of cultivation of agricultural crops into production; 2. Electrification and automation of the industry; 3. Introduction of resource-saving technologies, mechanization, melioration, development of breeding potential. Also it shall be noted that for growing the crops using intensive technology it is required to use plastic varieties, with economically valuable traits that would have a high yield potential and be able to withstand various stresses. From an economic point of view, different breeds differ from each other primarily in the fact that under the same conditions they can produce different yields. The average increase in grain yield due to the sowing of a new, better breed is usually at least 2 centners per 1 ha, and sometimes reaches 8–10 centners per 1 ha or more. The use of high-quality seeds of the best released breeds is one of the most accessible and cost-effective ways to increase the yield and gross harvest of agricultural products.

Energy-efficient environmentally friendly electric device for the destruction of weeds by heating them
Authors: Denmukhammadiev A M , Matchanov O Q , Sobirov E E , Azamov S S 
Published: August 2022

Abstract
Weeds damage cultivated agricultural plants. There are many ways to control weeds. These include biological, chemical, mechanical and electrical methods. With an increase in sown areas, the types of weeds increase. On the one hand, weeds perform some useful functions, such as transporting moisture and trace elements from the soil, increasing the diversity of flora. However, with a very large number of weeds, the yield can be reduced by up to 50%. The use of pesticides to kill weeds leads to environmental pollution and deterioration of human health. Certain types of chemicals cause cancer disease. In recent years, smart technologies have appeared for the local application of pesticides in weed control. At the same time, there is a decrease in pesticides up to 90%. Intelligent technologies allow effective control of weeds. Burning weeds directly in the fields leads to a decrease in soil humus and, subsequently, to a decrease in land productivity. We have developed a method and a device for the destruction of collected weeds directly on the field using energy-efficient electric contact heating. This technology and electrical circuit can be connected to both centralized power supply and autonomous power (diesel or solar power plants). In order to save energy resources, an electronic model for the use of a solar beam concentrator is also proposed.

Abstract
The object of study is the process of bending the cotton stalk in an upright position to the side, and the technological design parameters of the bender which performs it. Bending the stalks to the side edge, in the direction of the aggregate movement, is the initial process of the proposed technology. The quality of the process is assessed by the fact that the stalks are laid on the bottom of the lateral axis along its axis of symmetry. The placement of the stalk at an angle of up to 30 ° to the axis of symmetry satisfies the requirement. Then the buried cotton stalks will not interfere with the agro-measures of inter-row cultivation. The research used the principles of theoretical and agricultural mechanics, higher mathematics and methods of mathematical planning of experiments. The process of bending the cotton stalk to the side, and the amount of force acting on the stalk by determining the stiffness, size, characteristics of the stalk, as well as the mounting angle and height of the stalk, were determined. The results were analyzed by constructing their graphs. The effects of the centering height and angles of the bender on the amount of force bending the stalk are determined by the experiment. As a result of theoretical and experimental studies, the mounting height of the bender on the ridge surface for laying the stalks at a small angle to the axis is h=15 cm, angle relative to the direction of movement γ=43° and the radius of curvature of the bender r=96 mm was determined.
