Abstract: 
Application of biofertilizers, especially associative biological nitrogen fixation chemical fertilizers is most important strategy for integrated plant nutrition in sustainable management of agro-ecosystems and their production increase by adequate input sustainable agriculture (AISA) system. In order to study the associative biological nitrogen fixation and nitrogen chemical fertilizers factorial experiment based on randomized complete block design with four replications was conducted at research field of varamin Azad University, Iran in 2007 on late maturity maize (Zea mays L.) single cross hybrid (SC700). The factors in this study included Azospirillum, Azotobacter and nitrogen chemical fertilizer. Azospirillum consisted of two levels (one with and one without using), Azotobacter consisted of two levels (one with and one without using azetobacter) and nitrogen chemical fertilizer consisted of two levels (application of net nitrogen chemical fertilizer at the rate of 180 Kg/ha and application of Net nitrogen chemical fertilizer at the rate of 90 Kg/ha). In grain milky stage, plant harvested and then single fodder yield per hectare, plant fresh weight per plant, plant leaf number, plant height and amount of fodder protein were determined. Results revealed that application of associative biological nitrogen fixation, not only resulted in increase in all the studied traits, but also can cuddown the, amount of nitrogen chemical fertilizers to some 50%.
