Yield, quality and profitability of potato tubers production in the application of fertilizers and chemical means of protection on sod-podzolic medium loamy soil

In the conditions of a field experiment on soddy-weakly podzolic medium loamy soil of the Vologda District, Vologda Region, the effect of applying fertilizer, ‘Lazurit, SP’ herbicide and ‘Albit’ complex preparation on yield and tuber quality of ‘Scarb’ table potato variety has been studied. Their combined application improved the marketability of the tubers, increased the starch content, and reduced nitrates.
