Abstract
Data on the influence of abiotic and anthropogenic factors on the formation of crop productivity are important for the productive process management system. This work examines the results of a long-term study of the influence of abiotic (weather conditions) and anthropogenic (mineral fertilizers, an integrated plant protection system) factors on the formation of potato productivity in the North-West region of the Russian Federation. Weather conditions were the most significant (23.6%) among all the factors affecting the potato yield in the North-West region of the Russian Federation. Integrated plant protection and mineral nutrition had approximately equal contribution to the yield, i.e. 16.6% and 18.6% accordingly. In 2012–2020, additional potato yield reached 56–65% on average under the influence of mineral fertilizers, depending on their dose, and 37–56% under the influence of integrated plant protection Program. The combined influence of these two factors, taking into account the effect of interaction, led to an increase of the potato yield by 114-157% as compared with the actual yield on unfertilized and unprotected control (143 centners per hectare).
Highlights
The production process control system is based on the knowledge of rational use of abiotic, biotic and anthropogenic factors for the formation of the yield of cultivated crops
According to the data published in the literature, the introduction of mineral fertilizers increases the yield of potatoes by 10-50%, the use of plant protection products – up to 75%, and in the years of strong development of diseases or mass reproduction of pests, it is much more [5,6,7,8]

Summary
The production process control system is based on the knowledge of rational use of abiotic, biotic and anthropogenic factors for the formation of the yield of cultivated crops. First of all, weather conditions that contribute or do not contribute to the realization of the productivity potential of cultivated plants in a particular year. According to the data published in the literature, the introduction of mineral fertilizers increases the yield of potatoes by 10-50%, the use of plant protection products – up to 75%, and in the years of strong development of diseases or mass reproduction of pests, it is much more [5,6,7,8]. Due to the combined use of mineral fertilizers and plant protection products, when the interaction effect is manifested, enhancing their separate effect, the maximum increase in potato yield is achieved [9,10,11,12,13,14]
