The article is devoted to the search for ways to reduce carbon dioxide emissions in the technological operation of plowing. Ways to reduce CO2 emissions were determined on the basis of computational experiments conducted using a mathematical model of an arable unit compiled according to the efficiency criterion - the minimum integral emission of carbon dioxide. Integral CO2 emission, in addition to direct and indirect CO2 emissions over the life cycle of the arable unit, includes CO2, which could be absorbed from the atmosphere by the crop lost due to the influence of the parameters of the unit. The influence of the parameters of the tractor and the unit on the emission of carbon dioxide during its manufacture, technical and production operation is analyzed. Computational experiments were conducted to identify the influence of some external factors (field area, seasonal load volume, etc.) on the efficiency of the arable unit.

In the qualitative improvement and replenishment of the main dairy herd with a productivity of 7000 to 9000 kg of milk by purebred animals, the role of certified breeding farms producing breeding material is great. Data on providing the dairy cattle breeding industry with breeding material (bull semen, breeding stock) show that the cattle breeding industry is largely dependent on import supplies. Thus, the share of imported breeding stock in the domestic market for 2021 in the Russian Federation amounted to 36.3%. An analysis of breeding business development on the example of the Republic showed that 47 certified breeding farms operate on the territory of the Republic. In total, these farms keep a little more than 183 thousand heads of cattle, of which more than 150 thousand heads, or 82%, are identified as breeding. In 2021, the breeding farms of the Republic sold livestock products (milk, offspring) in the amount of 11,693 million rubles. Not all breeding farms perform their main function - the cultivation and sale of breeding stock. So, in 2021, out of 47 breeding farms, 25 did not sell breeding stock, which means that they grow breeding stock only to meet their own needs, and not for sale. The remaining 22 breeding farms had about 2% of the proceeds from the sale of breeding young animals, while, in advanced farms, it reaches 28% of the total cash proceeds of cattle breeding, which shows a low level of raising commercial breeding young animals in the breeding farms of the republic. Of the 43 municipal districts of the republic, in 26 as of 2022, there were no breeding farms, which indicates a low provision of municipal districts of the republic with breeding farms. In these municipal areas, the average productivity of the dairy herd for 2017-2021. amounted to 4857 kg of milk, with an average productivity of cows in the republic of 5521 kg. The exception is the Aktanyshsky municipal district, where the average productivity was 6395 kg. About 60% of breeding farms operate on the territory of 5 municipal districts of the republic, in which the average productivity of cows over 5 years ranged from 7503 kg to over 8618 kg of milk per year. In productivity groups: 7504-8617 and more than 8618 kg per one municipal district there are from 5 to 6 breeding farms in general, i.e. the coefficient of provision with breeding farms, calculated as the ratio of the number of breeding farms to the number of municipal districts in the group, is 5.0-6.5. Regression analysis of the dependence of the productivity of cows on the provision of breeding and farms in municipal areas shows a significant dependence of the productivity of cows in productivity groups, ranging from 4162-5275 kg to the productivity group over 8618 kg, on the provision of their breeding farms. The regression equation constructed for groups of municipal districts with cow productivity over 4162 kg indicates that an increase in the provision of breeding farms in the municipal district leads to an increase in the average annual milk yield by 2641 kg.

Researches were conducted for the purpose of development of a method of calculation of emission of carbon dioxide by machine and tractor units on technological operations in crop production at cultivation of grain crops. The criterion of optimization of parameters and operating modes of soil-cultivating, sowing and other units – the minimum emission of carbon dioxide in the atmosphere at their production, maintenance and production operation is offered. Feature of the offered method is the fact that it considers the influence of parameters of the equipment on losses of a potential harvest which to avoid at today's level of development of the equipment and technologies it is impossible. Formation of a harvest results from absorption by carbon dioxide plants from the atmosphere and, partially, from the soil. Carbon dioxide (CO2) which the lost harvest could absorb from the atmosphere is removed from a circulation, so remains in the air, and in our technique it is attributed to CO2 released into the atmosphere at production, service and operation of the unit. In article the method of calculation of the amount of the carbon dioxide necessary for the formation of unit of a grain part of a harvest and not grain part accompanying it is in detail considered. The formula which allows to calculate the mass of carbon dioxide in kg for the formation of grain weighing 1 kg is offered. It became clear that from grain crops on formation of unit of a harvest, most of all CO2 from the atmosphere is absorbed by winter rye (about 3 kg/kg), further corn (2.8 kg/kg by theoretical calculations). Leaning on these researches, the mathematical model of operation of machine and tractor units on technological operations on preparation of the soil for crops and crops by the offered criterion of optimization is developed. An inspection of operability of the offered method by carrying out computing experiments with use of the created mathematical model on technological operation – preparation of the soil heavy disk harrows is carried out. During calculations of influence weight of the tractor, power of its engine, width of capture of the unit and working speed of the unit on carbon dioxide emission became clear. The minimum emission of carbon dioxide, for conditions of carrying out a computing experiment, is provided weighing tractor of 145 kN. The tractor weight deviation towards increase or reduction leads to growth of emission of carbon dioxide in the atmosphere.
