Investigations were conducted in 1988-1989 in Timiryazev Agricultural Academy. Productivity of early ripening onion variety Vesta and mid-ripening leek strain sample TSKhA-T was investigated; it was studied on soddy-podzolic medium-textured loams with sowing density 180 and 350 thousand plants per ha and different backgrounds of mineral nutrition: without fertilizers; with applying 90N60P90K, 180N80P120K entirely and in rows. The varieties studied varied in the amount and intensiveness of absorbing the main nutrient elements, their removal and consumption, varying in its turn, with density of planting rate and way of applying fertilizers. The efficiency of using nutrient elements from fertilizers by leek greatly depended on conditions of moistening. Data on removal of nutrient elements - N - 276; P2O5 - 45 and K2O - 195 kg/ha - may be used as normative for leek culture. Optimum variants of the experiment may be recommended for production.
