The applied methods of applying fertilizers for cotton in Uzbekistan do not fully ensure the supply of nutrients to the plant's root system. The study aims to substantiate the technological process of uniform distribution of fertilizers in the root development zone and the parameters of coulters. When the fertilizer is distributed in the root development zone in tiers and the right ratio, the coefficient of their use increases, and the yield of cotton increases. The research uses the laws and rules of theoretical mechanics, mathematical statistics, mathematical planning of experiments, and the methods given in existing regulatory documents. The technology of forming new ridges instead of existing ridges and new furrows instead of existing furrows in fields with harvested husk with simultaneous fertilization and an improved chisel cultivator-fertilizer with comb-forming agents for its implementation, as well as the results of theoretical studies to substantiate the main parameters of the tuk coulter chisel-cultivator are presented. The study determined the parameters of universal fertilizer Coulter chisel-cultivator of fertilizer: the base cone of the diffuser in the form of an ellipse with minor axis width 10 mm, height tool provider relative to the upper base of the truncated cone of 60 mm, and a diameter of a half-cylinder of 20 mm.

Рассматривается решение одной из важнейших проблем при посеве зерновых культур – равномерность распределения семян по длине и глубине борозды, при исключении забивания выходного отверстия семяпровода. Приведены теоретические исследования сошника с гасителем скорости семян для посева зерновых культур, а также описана конструкция разработанного сошника. Отмечен ряд существенных недостатков современных сошников зерновых сеялок. В результате теоретических исследований составлены уравнения для определения времени движения семени, расстояние между центрами масс от первого удара до второго, скорость семени при падении, время падения семени при выходе из семяпровода, уравнение движения семени при выходе его из семяпровода, а также получены значения выше указанных значений, которые обеспечат повышение качества работы сошника, что скажется на повышении равномерности распределения семян по длине рядка и урожайности зерновых культур. In the article, one of the major issues of planting crops is considered. It is the problem of the uniform distribution of the seeds along the length and depth of the furrow, when excluding the clogging of the outlet of the grain tube. Theoretical studies of a coulter with a seed velocity suppressor for planting grain crops are presented, and the design of the developed coulter is described. Several significant disadvantages of modern coulters of grain seeders are noted. As a result of theoretical studies, the equations to determine the movement time of a seed, the distance between the centres of mass from the first strike to the second one, the seed velocity in the fall, the fall time of a seed when leaving the grain tube, the equation of the seed motion at its leaving from the grain tube are composed. Moreover, the values of these equations are obtained, which ensure improved coulter quality. It can have an impact on increasing the uniformity of seed distribution over the length of the row and grain yields.

To improve the quality and energy indicators on the front plow in front of the housings, the angle axes are installed in the form of a triangular wedge. The purpose of the study is to substantiate the parameters of the angle-lift of the front plow, which provides high-quality performance of the technological process according to agrotechnical requirements with the lowest energy costs for smooth, rowless plowing. The research uses the laws and rules of theoretical mechanics, mathematical statistics, mathematical planning of experiments, and methods of strain measurement, as well as the methods given in existing regulatory documents. Based on the study of the process of interaction of the carbon monoxide with the soil, analytical dependences are obtained that allow us to determine the parameters of the carbon monoxide. According to the results of theoretical and experimental studies, it was found that the required quality of tillage with a front plow following the established agrotechnical requirements with minimal energy consumption is provided at the height of 22 cm, a length of 27 cm, a wing angle of 32° and an angle of inclination of the side face of 36°.

The article presents the results of theoretical studies of the technological process of operation of multi-blade working bodies of rotary type, intended for the distribution of solid organic fertilizers. To determine the length of the blades of the last row of rotors, and accordingly the overall dimensions of the spreader, theoretical dependences of the range of fertilizer particles on the radius of the blades are obtained, which made it possible to determine the size of the blades that provide the required performance of the rotary spreader. Considering the uniform distribution of fertilizer particles over the sieving width, the dependences of the “limiting” zone of loading of the blades (the maximum thickness of the layer of fertilizers captured by one blade) on the angle of their inclination at different lengths of the blades were obtained, which showed that when applying fertilizers with medium and large doses, several rows of blades. Computational experiments were carried out, during which, the number of rows of blades and the ratio of the lengths of the blades of different rows were determined to obtain the smallest unevenness depending on different doses of fertilizer application. As a result of mathematical modeling, the dependences of the working insertion width on the angle of inclination of the blades of the rotor rows relative to the radial position are obtained for various second-time supply of material, using which rational values of the angle of inclination of the blades are found.

The article reveals information links between acoustic properties and parameters of the metal microstructure. A large number of regulatory documents and a lack of scientific concept lead to the system errors when estimating condition of both longterm operating metal and the product in the whole. The article considers methodology for developing a combined technological process based on modification of properties and change of the coatings' surface layer parameters, with an estimation of their efficiency in terms of productivity based on the criterial use of productivity principles. The analysis of technological activities for the productivity coefficient and the criterial estimates confirmed their efficiency.

The paper deals with the problem of utilization of red mud which is a waste product from alumina production using the Bayer method. The principal possible use for the red mud of JSC “Bogoslovsky aluminum plant” (Sverdlovsk region) for the compositions based on Portland cement is shown. It was found that the mud introduction accelerates beginning of the cement paste setting and thickens the paste reducing its mobility. It is concluded that the introduction of red mud up to 30 % is justified in terms of strength indicators. The work is carried out using mathematical planning of experiments.

In the framework of this work, the main regulatory documents on this topic are analyzed. It is noted that the qualification requirements are not identical to the presence of a document confirming the right to drive a vehicle. Qualification requirements are the requirements for the knowledge, skills, and professional skills of the driver. A legal conflict was established for drivers who received a driver’s license earlier than 12/12/2014: the presence of a Russian national driver’s license of the corresponding category makes it possible to speak of non-compliance with professional requirements, and in turn, the lack of knowledge, skills and professional skills in working with various types of tachographs clearly indicates a mismatch with qualifications requirements. It is noted that to confirm the availability of skills, professional skills in working with various types of tachographs to persons who have received a driver’s license before 08/12/2014, only a document confirming training in the training program that meets the requirements of Order of the Ministry of Transport of the Russian Federation of January 17, 2012 No. 7 can be confirmed.
