Abstract
The studies were conducted to assess the effect of mineral and various types of organic fertilizers on the yield and quality of potato tubers under irrigation in order to develop a crop fertilization system. The work was carried out in 2023-2024 on leached chernozem of Zakama zone of the Republic of Tatarstan. The scheme of the field experiment included studying the following options on dry land and under irrigation: without fertilizers (control); N60H60R90; manure 60 t/ha; N60H60R90 + manure; N60H60R90 + green mass of oilseed mustard 12 t/ha (green manure); N60H60R90+ green manure + winter wheat straw 4/5 t/ha; N60H60R90+ manure + straw; manure + green manure + straw. Agrometeorological conditions in 2023 were relatively favorable (HTC - 1,06), in 2024 - dry (HTC 0,6...0,8). On average, over 2 years, the potato yield with irrigation was higher than in dryland farming, depending on the nutrition background by 8,54...18,57 t/ha. The maximum yield of tubers per unit area in the experiment (41,49 t/ha) was noted in the variant with the introduction of N60H60R90, manure and straw, which is 21,37 t/ha more than in the control. The starch content in tubers, regardless of the nutrition background, decreased by 0,6...1,6% with irrigation, compared to dry farming.The total starch yield per unit area increased due to the increase in yield. In the variant with the introduction of N60H60R90, manure and straw, both on dry farming and with irrigation, the starch yield was maximum - 3,59...6,03 t/ha. The highest economic indicators were noted in the variant where mineral fertilizers were applied together with manure and straw - the profit from irrigation was 217,200 rubles/ha, from dryland farming - 94,000 rubles/ha, which is 89,490 and 39,060 rubles/ha more, respectively, than when applying only mineral fertilizers.
