Efficiency and unity of planting and harvesting complexes in the grain subcomplex

Abstract The article uses a systematic approach when considering the implementation of field work by planting and harvesting complexes. It was established that for the full use of the capabilities of these complexes at minimal cost, mechanized work must be carried out at the maximum values of the shift time utilization factors. The tabular form shows the values of the shift time utilization factors for the conditions of the Non-Chernozem Zone of Russia. The choice of work strategy determines the maturation rate, weather conditions, and the availability of technical equipment. Numerical compositions of planting and harvesting complexes per 1 ha are proposed, which are presented in tabular form when aggregated with tractors of class 1.4; 2; 3. Effectiveness evaluation of the complex functioning should be based on the activities of all subsystems to implement the work plan. Such an evaluation of the daily work of the complex can serve as a coefficient of work intensity equal to the ratio of the amounts of actually completed work to the planned ones. The conclusions establish ways to improve mechanized processes for planting and harvesting grain crops, and as an optimal option, the option of maximizing the use of shift time due to the introduction of new organizational and technical forms was chosen. As a result, a mathematical model for the functioning of planting and harvesting complexes in the production of grain crops for the Non-Chernozem Zone of Russia, which can also be used for other regions, was developed.
