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.
