CHANGES IN THE NITROGENOUS COMPONENTS OF RAPESEED (BRASSICA NAPUS) GROWN ON A NITROGEN AND SULFUR DEFICIENT SOIL

Abstract

The analyses for the amounts of nitrogenous constituents of rapeseed (Brassica napus L.) grown under conditions of nutrient deficiency have shown that additions of ammonium nitrate (44.8 kg of N/ha), triple superphosphate (22.4 kg of P₂O₅/ha), and potassium sulfate (205.1 kg of K₂O and 89.6 kg of S/ha) to the soil increase the amounts of protein deposited in mature seed and produce changes in the relative proportions of the nitrogen-containing seed components.
