Abstract

In order to evaluation of yield and yield components of sunflower in response to different nitrogen fertilizer sources, an experiment was conducted with different chemical and biological nitrogen fertilizers and one cultivar of sunflower cv. Master . These treatments were arranged into a factorial experiment based on RCBD design with four replications. Chemical nitrogen treatments were: No using of nitrogen, Urea application, Ammonium sulphate, and Ammonium nitrate phosphate application. Biological nitrogen based fertilizers was included of application and no applied of “Nitroxin” in combination with all chemical nitrogen treatments. Results showed that, Ammonium sulphate produced the highest seed yield. Integrated application of this fertilizer with Nitroxin, produced less yield than Ammonium sulfate alone. But in the other treatments, Nitroxin increased the seed yield.
