Use to biofertilizer is one of the base of sustainable agriculture. This experiment factorial in a randomized complete block design with three replications in 2013 and 2014 Qazvin Province two years done. Treatments of cultivation :1- pure corn,2- intercropping of maize and increasing of 25% grass pea ,3-intercropping of maize and an increasing of 50% grass pea, 4-pure grass pea, Treatments of fertilizer: 1-chemical,2- cow manure (base) chicken fertilizer top dress,3- cow manure (base) and chemical top dress,4-cow manure (base) and chemical top dress and chemical spraying, in recent three treatment Along with corn and grass pea seed inoculation with Azotobacter and mycorrhiza were location of cultivation. The results indicated that the interaction of fertilizer and cultivation levels, maximum corn grain yield with an average 9790/27 kg/ ha of 50% spraying livestock chemical corn grasspea and the highest corn forage yield with an average of 84230/16 kg /ha of treated corn ,Grass pea 50% of animal chemical, the highest grain yield of 1400 kg /ha and forage 46020 kg /ha of pure grass pea chemical manure, respectively.The result of this research showed that in order to decrease of use to chemical fertilizer and increase the health , The combination of manure and chemical fertilizers and intercropping is recommended.
