Two field trials were carried out at Giza Governorate during 1990 and 1991 seasons to study the effect of four levels of nitrogen i. e. 30, 45, 60, and 75kg N/fed. and three levels of potassium, i.e. 0, 24 and 48kg K20/fed on sunflower yield and its components as well as oil yield. Results indicated that nitrogen levels significantly increased plant height, head diameter, seed yield/plant, 1 00-seed weight and seed yield /feddan as well as oil yield/feddan, while seed oil content was depressed. Application of 60 kg N/fed. produced the highest significant seed and oil yields /fed. Seed and oil yield/ fed. as well as seed oil content were increased by adding potassium levels, and 48kg K20/fed produced the highest yield of seed and oil/fed. However , no signifcant difference was found in most cases between 24 and 48 kg K20/fed.
