Efficiency of potato production: analysis of variation and differentiation of regions of the Russian Federation

The article makes an attempt to research the statistical dependencies characterizing the potato production efficiency in the subjects of the Russian Federation. Solutions to food security problems are revealed through the achievement of threshold values for the production and self-sufficiency of individual products. So, for the production of potatoes, the threshold value of food security is set at 95%. Achieving threshold values is extremely important for achieving food security, but it is equally important to assess the role of Russian regions in the production of potatoes, as well as to assess the efficiency of production in agricultural organizations, private household plots, and farms. The conducted economic and statistical analysis shows that the average yield for agricultural organizations is higher than for personal subsidiary farms by 1.5 times. Comparison with farms is also not in favor of the latter. Agricultural organizations have the opportunity to observe the technology of potato cultivation, buy new varieties, high-yielding and resistant to pests, apply fertilizers. Small farms are unable to meet the requirements of technology due to their scale, which affects the degeneration of the genetic line and the fall in yield.
