Justifying the Use of Industrial (Dutch) Technology for Potato Cultivation in the Nonchernozem Zone of Russia

Abstract

The studies were conducted on gray forest soils of OOO Agriko-Eurasia of Voskresensky raion (Moscow oblast) in 2015–2017 in order to substantiate the adaptive industrial (Dutch) technology of potato cultivation depending on the fertilizers and varietal characteristics. The study of the growth processes of potatoes showed that, when applying industrial technology, the development phases came 3–8 days earlier compared to traditional technology. Their earlier onset was noted on variants 10 (Arizona variety) and 14 (Roco variety) with the use of industrial technology and the addition of potassium sulfate during the planting period. Studies have shown that the highest yields of the studied potato varieties were obtained when it was cultivated by industrial technology with the addition of potassium sulphate (N120P90K120) during planting at a dose of 60 kg of a.e./ha. Assessment of the potato tubers' quality according to the biochemical composition and content of heavy metals and nitrates is given. It has been established that the highest quality indicators of potatoes are obtained when applying industrial technology with the addition of potassium sulfate at a dose of 60 kg of a.e./ha during the planting period.
