Abstract
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.
