In assessing the optimal composition of machine and tractor fleet nomenclature and quantitative composition of parks of technical means and some parameters of production technology are used as varying variables, leaving the timing of mechanized fieldwork fixed. At the same time, changing the duration of mechanized operations in the most intense periods of the field season can significantly affect the amount of the basic means of mechanization as a part of machine and tractor fleet, the value of investments in its formation. The article used a method of determining the composition of the machine and tractor fleet of agricultural organizations considered the "flexible" duration of the mechanized operations in field and based on the iterative adjustment of the results of the optimization of machine and tractor fleet by the criterion of the minimum difference between savings investment and value of crop losses. The analysis showed that the economically viable term of harvesting of winter crops for domestic combine harvester Acros-530 is a period of 16 days. The article analyzes the economic efficiency of the different periods of the harvesting campaign using imported agricultural machinery. This work presents a sensitivity analysis of the effect of reducing the need to combine at different periods of cleaning of grain crops to the level of prices for products and equipments

The article presents the results of the analysis of the national beef cattle breeding, including the dynamics of the stock and amounts of beef production in Russia and the Krasnodar region. The study has noted the high degree of dependence of the domestic market from imports of this product. It showed a positive international experience of beef production based on feeding animal meat breeds. This article gives an analysis of the sub-sector in the country and across its regions, shows the availability of domestic producers of beef natural pastures in comparison with countries with developed beef cattle. We have also noted positive experience of feeding cattle meat breeds in separate regions of the country

In assessing the optimal composition of machine and tractor fleet nomenclature and quantitative composition of parks of technical means and some parameters of production technology are used as varying variables, leaving the timing of mechanized field work fixed. At the same time change the duration of mechanized operations in the most intense periods of the field season can significantly affect the amount of the basic means of mechanization as a part of machine and tractor fleet, the value of investments in its formation and operating costs. The article proposes a method of determining the composition of the machine and tractor fleet of agricultural organizations considered the "flexible" duration of the mechanized operations in field and based on the iterative adjustment of the results of the optimization of machine and tractor fleet by the criterion of the minimum difference between savings investment and value of crop losses. The realization of the algorithm described above will allow determining the optimal composition of machine and tractor fleet of agricultural organizations considering the possibility of changing the duration of mechanized operations in field in the most intense periods. At the same time the resulting calculations decision takes into account the compromise between the growth of production losses by increasing the duration of mechanized operations and a reduction in capital costs for the formation of the machine and tractor fleet
