Abstract

SUMMARY Combined effects of nitrogen at 25 and 50 kg/ha as calcium ammonium nitrate and phosphorus at 30, 60 and 90 kg/ha as triple superphosphate were studied on the composition, germination and emergence of sunflower seeds. Maximum protein (26·2%) and lipid (45·8%) with the maximum emergence (85·0%) was obtained from seeds produced by crops raised in soil with 50 kg/ha of nitrogen and 60 kg/ha of phosphorus. Lowest protein (21·6%), lipid (40·8%) and 45·0% emergence were obtained from seeds of crops raised on soil with the basal level of nitrogen and phosphorus.
