AB  - In order to evaluate the effects of type and amount of nitrogen fertilizers on control of broomrape in prescience of sunflower, as host plant a factorial experiment in randomized complete block design were down in Saveh Islamic Azad University with 4 replication. First factor was type of fertilizer (urea, amonium nitrate, amonium phosphate). Second factor was concentration nitrogen (0, 2, 4 and 5 ppm). Results of this experiment showed that effect of type of nitrogen fertilizer on dry seed weight, dry weight of broomrape and number of broomrape is significant (p&lt;0.01). Highest dry weight of stem and leaf of sunflower were in concentration of 4 ppm of amounium nitrate. In concentration of 5 ppm of ammonium nitrate, ammonium phosphate and urea fertilizers, highest seed of sunflower weighted. Lowest dry weight of broomrape was in concentration of 2 and 4 ppm of ammonium nitrate and least number of broomrape were counted in 5 ppm of urea form of fertilizers.
