Article data on the average moisture and hardness of the soil before the tests are carried out. The combined plow with an active working organ developed in field tests 630Cwas added to the Claas ARION tractor, the theoretical and working depth, working speed were determined and the principle of operation was presented. The obtained results show that all the quality parameters of the plow with an active working organ, i.e. coverage width, processing depth, completeness and depth of burial of plant residues, soil compaction quality and the height of irregularities on the surface of the plow fully meet the agrotechnical requirements. given. The developed combined frontal plow with an active working body reliably performed the specified technological process compared to the plow with a passive working body and O’P-4/5-40, and its results are presented. Research of the results reliability of research modern style and measure from tools used without held, combined frontal plug active the work bodies parameters theoretical in terms of in justification higher math, theoretical of mechanics main the rule and methods action done, experiences to the results mathematician statistics methods with processing given, theoretical and practical studies of the results mutually adequacy, done studies based on work developed active the work organ the field of tests positive results and to practice current done with explained.

The article protection of agricultural crops and gardens from various diseases and pests, chemical feeding of crops, fight against weeds, defoliation processes, traditional dispersion analysis of highly dispersed droplets formed by resource-efficient and high-performance sprayers, determination of the distribution pattern of drops in a dynamic line for a long time in order to simplify this process, to save time spent on computational work, it is proposed to use templated miniature drop cards for dispersion analysis. Mathematical-statistical analysis was performed on the basis of the collected dynamic series of tiny drop cards. In this case, the arithmetic mean value of the indicators, the mean square deviation, the coefficient of variation, the shift values for the dynamic series, the differential function of the probability of each interval for the Weibull distribution law in assessing the reliability level of highly dispersed drops, the theoretical distribution R(xi) and the expected theoretical distribution of drops in the interval (mi) probability is determined. Empirical and theoretical graphs of the Weibull distribution law are presented.

The article presents the results of theoretical and experimental testing of the machine made as a result of the research on the basis of the scheme and parameters of the cultivator, which processes the soil between rows and rows of vines with a low cost, including vine rows with soil hardness varying between 1.4-1.8 mPa, the circumference of the bushes and The required tractor power is 21.53-35.09 kW when the resistance changes in the range of 12.41-16.37kN when moving the range of working speeds in the range of 1.45-1.8 m/s. In the tillage system, it is important to loosen the rows between the vines without overturning them. Gray soil soils in Uzbekistan have different mechanical composition and are very poor in humus. Cultivation of the vineyard soil at a depth of 20-25 cm for many years leads to the formation of a plow heel, as a result of which the water-physical properties of the soil and the development of the root system deteriorate, which negatively affects the growth and yield of the plant. The leaves of the vines turn yellow, they drop their leaves early, the amount of fruits that can be obtained decreases, and accordingly the percentage of fruits that fall to the ground increases. A decrease in the water permeability of the soil prolongs the irrigation time, as a result of which water is used inefficiently. Deep softening improves the water permeability of the soil and, accordingly, increases the coefficient of effective plant use of moisture entering the soil.
