摘要：Today, with the development of environmental pollution and health that is obtained from the use ofchemical fertilizers, production and use of biological fertilizers (Biofertilizer) is considered as animportant approach in the field of biotechnology, soil and agriculture in the world's interest toinvestors. In order to reduce the use of nitrogen fertilizer in agriculture of corn, a research by usingrandomized complete block design with split plot with three replications was conducted in 2013. Theamount of nitrogen fertilizer at four levels, including the recommendation based on soil test (control),and 25, 50 and 75 percent of the recommended intake of bio-fertilizer as the main factor andvermicompost contains no biological fertilizer vermicompost (control) and consume 5, 7 and 9 tons perhectare bio-fertilizer were considered as sub plots. The results showed that application of differenttreatments has significant impact on corn yield, as 9 tons per hectare with a yield of 7.11 tons perhectare bio-fertilizer produced the highest grain yield. Effect of nitrogen fertilizer on yield wassignificant and the highest yield in the treatments of nitrogen based on soil test (control) was obtainedwith a yield of 5.11 tons per hectare.
