Abstract
The research was conducted to study the effect of zeolite and metallocene (Cu) together with mineral fertilizers on the yield and quality of potatoes of domestic and foreign varieties. The work was carried out in 2020-2021 in the Republic of Tatarstan on gray forest heavy loamy soil, which was characterized by the following agrochemical indicators: humus - 3.2%, pHKCl - 6.8 units, Hg - 0.7 mg-eq/100 g, S - 23.12 mg-eq/100 g, alkali. - 84.0 mg/kg, R2O5 and K2O (according to Kirsanov) ‒ 143 and 107 mg/kg, respectively. The study used a randomized complex block project with three repetitions. The total area of the experimental site was 74.7 m2, the estimated area was 35 m2. The experimental scheme included a variant without fertilizers (control), three backgrounds of mineral fertilizers (N100P120K120, N120P140K140, N140P170K170) with the addition of zeolite at a dose of 5 t/ha, metallocene (Cu) at a dose of 2 l/ha as foliar top dressing in the budding phase, or a combination of all these. The combined use of N140P170K170, zeolite and metallocene (Cu) ensured a maximum increase in the yield of the domestic potato variety Salsa to 28.84 t/ha and the foreign variety Arosa to 26.04 t/ha, or 2.2 and 1.8 times, respectively, compared with the control. At the same time, the starch content increased from 21.1% to 23.2% and from 21.6% to 25.2%, respectively, and the dry matter content increased from 13.9% to 16.0% and from 14.4% to 18.0%.
