The effect of non-root treatment with Si-containing agrochemicals on the yield and quality indicators of potato tubers when growing for seed purposes is evaluated. The experiments were laid at the experimental base Korenevo of the Russian Potato Research Center in the Lyubertsy district of the Moscow region (Korenevo village) in 2019–2020. The effect of non-root treatments with silicon-containing agrochemicals from PhosAgro in increasing doses on the productivity of seed potatoes of the Golubizna variety was studied. Spraying of plants with the preparation from 100 to 1000 g/ha in the physical weight of the agrochemical was carried out in the budding phase – the beginning of flowering at the consumption of the working solution of 300 l/ha. The scheme of the experiment included eight variants in a four-fold repetition. The standard power supply system is N90P90K135. The structure of the crop of potato tubers was determined by weighing the fractions from each plot, taking into account the transverse diameter: small fraction – less than 30 mm; seed fraction – from 30 to 60 mm; food-tubers more than 60 mm. Spraying potato plants with silicon-containing agrochemicals during the budding phase – the beginning of flowering increases the gross yield and marketability of seed tubers, as well as increases the yield of nutritionally valuable components per hectare. The maximum gross yield of tubers was obtained in variants with the introduction of 270–384 g of SiO2/ha. The increase in the yield of tubers at the same time amounted to 4.9–8.5 t/ha. In turn, for the variants with a dose of 270–384 g of SiO2/ha, the best starch yield indicators were achieved (8.6–8.7 t/ha) and vitamin C (7.9–8.3 t/ha).
Key words: potato, Si-containing agrochemical, mineral nutrition.
