Abstract: Scientific research in 2022-2023. In order to determine the actions of agrotechnical practices with further identification of priority measures to increase climate productivity and economic efficiency in the conditions of the Predkamsk and Trans-Kama zones of the Republic of Tatarstan. Field experiments were carried out on gray-forest heavy loamy soils of the experimental field of the Kazan State Agrarian University and leached chernozem soils of medium loamy granulometric composition in the crop rotation of the peasant farm "Davletov N.G." Mzylinsky district of the Republic of Tatarstan. In accordance with the objectives of the research, a two–factor experiment scheme was chosen: factor (A) – irrigation in the budding phase, first watering and tuberization - two irrigations with an interval of 12 days, factor (B) – nutrition background: without fertilizers (control); N60P60K90 kg of d.v. per ha; N60P60K90 + 60 tons of manure per ha ga . On average, over 2 years in the experimental field "Agrobiotechnopark" of the Kazan State Agrarian University, on a natural background of nutrition from the use of irrigation, the yield increase amounted to 5,9 tons of tubers per hectare compared with the option without artificial sprinkling, and in combination with the introduction of N60P60K90 per hectare, the yield increase was 39% more compared with the control. The maximum yield increase of 11,2 t/ha was provided by the option using sprinkling and with the addition of N60P60K900 + 60 tons of manure per hectare. In bogar, the yield increase from the application of only mineral fertilizers (N60P60K90) amounted to 1,9 t/ha, and in combination with organic matter (60 tons of manure per 1 ha) – 4,7 t/ha. The average data for 2 years in the conditions of the farm "Davletov N.G." revealed the advantage of joint application of mineral fertilizers with organic matter during irrigation. The increase in yield relative to the control was 15,5 tons of tubers per 1 ha. In the conditions of gray forest soils of the Ancestral region of the Republic of Tatarstan. The largest net income from 1 ha is 232,8 thousand. rubles, with the lowest cost of 1 ton of potato tubers – 4516 rubles, the highest level of profitability – 165,7% was achieved on the variant N60P60K90 + 60 tons of manure per 1 ha with artificial sprinkling. In the conditions of chernozem soils of the Transcamian region of the Republic of Tatarstan, where the farm "Davletov N.G." is located, the maximum net income of 334,9 thousand rubles /ha with a profitability level of 234,6% was also achieved on the variant when applying N60P60K90 + 60 tons of manure per 1 ha during irrigation.
