Abstract

While Azetobacter bacteria in the rhizosphere, in addition to providing a part of the nitrogen will be production of crop growth promoting, root growth and yield. Acording to this, two experiments were in order to the effects of Azotobacter and nitrogen carried out on irrigated barley (Bahman variety) on root and shoot growth at booting stage (experiment 1) and root and shoot growth and also grain yield at ripening stage (experiment 2) in pot condition in Songhor town (cold area), Kermanshah Province as a factorial in based a completely randomized design (CRD) with three replications during 2014-2015. Factors included Azotobacter chroococcum (0, 100 and 200 g ha-1) and nitrogen fertilizer (0, 50, 100, 150 and 200 kg ha-1) from urea source. Analysis of variance showed that the effects of Azotobacter and nitrogen as well as interactions between them on all traits at two experiments were significant. The maximum of root traits, shoot dry weight and grain yield (21. 77 g pot-1) at booting (experiment 1) and maturity stages (experiment 2) obtained at Azotobacter (200 g ha-1) and nitrogen (200 kg ha-1) and declined amount of traits with decreased amount of treatments. But, this grain yield was not significant difference with Azotobacter (100 g ha-1) and nitrogen (100 kg ha-1) treatment (20. 85 g pot-1). Generally, the results of this test showed that the consumption of 100 g ha-1 Azotobacter has been saved about 100 kg ha-1 nitrogen and reduced bio-environmental problems.
