Abstract

In 2018-2020 the industrial extraction of primary nutrients from the vineyards of grape varieties “Kangun” and “Haghtanak” cultivated in the Talvorik community of Armavir region was investigated in conditions of bare fallow system of soil conservation. According to the investigations, in case of 7 t/ha yield and vegetative mass of the “Kangun” variety, 35 kg N, 9 kg P2O5 and 34 kg K2O is extracted, while in case of 10 t/ha yield and vegetative mass of the “Haghtanak” variety 49 kg, 15 kg and 67 kg respective nutrients are discharged.
In bare fallow conditions non-industrial nutrient losses are also recorded, which should be considered when determining the doses of fertilizers.
