Productivity of early ripe potatoes gene Vineta depending on density of landing and background of mineral nutrition on Grey forest soils of the forest-steppe in the Central Povolzhye

The role of mineral nutrition balance and the optimum area of nutrition in forming the harvest of early ripe potatoes gene Vineta on gray forest soils in Tatarstan Republic is studied. Productivity of culture was in many respects determined by interaction of the studied factors. During our researches it is established that grade is highly productive and during creation of optimum conditions of the area and background of nutrition of plants on the gray forest soil realizes the potential productivity. In the course of researches outstanding performance of introduction the doses of fertilizers of the crops of tubers of 30-35 t/hectare expected obtaining in case of landing density of 66,50 thousand pieces/hectare where crops of 30,12 and 36,69 t/hectare are received is established.
