Abstract
In order to evaluation of the effects of type and amount of nitrogenous fertilizers on germination and growth of Egyptian broomrape (Orobanchia aegyptiaca) and their ability in reduction of yield of sunflower, this experiment was conducted in the form of factorial experiment in a completely randomized block designs with 4 replications, in experimental greenhouse of Islamic Azad University of Saveh. With increasing of nitrogen fertilizers concentration, studied indices (bush height of sunflower, fresh weight of stem, leaf and crop of sunflower) were increased. In the other side, with increasing of nitrogenous fertilizer, the amount of broomrape germination was decreased. In interaction of type of nitrogenous fertilizers and amount of nitrogenous fertilizer, the maximum yield of sunflower seed in the concentration of 5 ppm of urea fertilizer was obtained. The minimum amount of broomrape germination also was obtained from the concentration of 5 ppm of urea fertilizer.
