Two field experiments were carried out to study the effect of different combinations of phosphorus and nitrogen fertilizers on growth, grain yield, straw yield, protein, P, K, Ca, Na and Mg contents in wheat grains. Nitrogen or phosphorus alone or together tended to increase treatments height, number of green leaves and their fresh weight, number of green leaves and their fresh weight, number of tillers, grain and straw yield than the control plants. The protein content of grains was affected by increases in nitrogen and phosphorus fertilizers. Superphosphate at rates of 100 or 200 kg/fed. alone increased protein, P, K and Ca contents in wheat grains. Also, mixture of 100 kg/fed. superphosphate plus 30, 60 or 90 N increased protein, P, K and Mg contents. Fertilization with 200 kg superphosphate/fed. and 90 kg N/fed. together, gave the highest grain and straw yield.
