Abstract: 

In order to study the effect of nitrogen and phosphorus rates on cultural circumestances, grain yield and fat contents of Safflower, an experiment was conducted on factorial randomized complet block design with 3 replications during 2005-2006 at two research station khosrowshahr and tikmehdash.
Factor A was nitrogen is 4 rates if 0, 50, 100, 150 kg.ha-1 and factor B was phosphorus in 4 rates of 0, 25, 50, 100 kg.ha-1 the highest grain yield was obtained with application of 150 and 25 kg.ha-1 nitrogen and phosphorus respectively at tikmehdash is first year. Maximum capitulum per per unit area was obtained in N150 and P50 and P100 rates. The highest seed per capitulum was measured in N100 P25. Among treatments, N100 had the maximum fat contents at seed. Maximum values in plant height, protein content capitulum diameter were obtained in N150. the highest plantheight and fat yield was recorded in N150 P100.
