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.}
