NUTRIENTS CONTENT IN PLANTS AND THEIR REMOVAL WITH THE ONION HARVEST

Abstract

There was investigated the quantity of consumption of basic nutrients by onions in this article. It was determined that the increase in the yield level increases the removal of nutrition elements. It was noted that by applying the full dose of mineral fertilizers N₉₀P₉₀К₉₀ separately, for the onion plant by forming 10 tons of commercial products 36 kg of nitrogen, 13 kg of phosphorus and 32 kg of potassium were used. The use of elements, by applying N₉₀P₉₀К₉₀ with aftereffect 14 t/ha of manure was not changed significantly, and by applying a half dose of mineral fertilizers (N₄₅P₄₅К₄₅) locally, together with 14 t/ha of humus, the use of potassium increased to 43 kg.
