Abstarct: In recent years environmental pollution crisis threaten human communities health. Also the particular use of chemicals compounds in agriculture due to their effects on soil micro-organisms may be decreased soil fertility. In this regards, an extensive effort to find suitable solutions for improving soil quality and crop production, purification and removal of environmental pollutants by maintaining the stability of natural ecosystems were started. Use of organic fertilizers and bio-fertilizers is another solution. This study was performed aimed to reduce the use of chemical inputs, along with efforts to increase the yield of chickpea (Cicer arietinum). In this study the effects of organic and bio fertilizers were investigated. Vermicompost at two levels (0 and 6 tons per hectare), humic acid at three levels (0, 8, and 16 kg ha) and plant growth promoting bacteria (PGPR) in 2 levels (inoculated and non-inoculated) were used in factorial complete block design with three replications. Morphological characteristics and grain yield of Kabuli chickpea were analyzed. The study was carried in a farm near the Javanrood city of Kermanshah in the spring of 1391 year. Analysis of variance showed that the effect of vermicompost and PGPR, were significant on plant growth and shoot dry weight at harvest stage. Straw dry weight, grain dry weight, 100 kernel weight and grain yield were also significant (p≤0.05), while humic acid had no significant effect on these traits. Interaction effect of vermicompost and humic acid on the number of nodes in root and the interaction effect of humic acid and PGPR on 100-kernel weight were significant at the 5% level. Mean comparison results showed that the combined effects of fertilizers had reduced the traits, but vermicompost treatment increased attributes without application the other fertilizers. PGPR treatments without other fertilizers application had no significant effect. The vermicompost and PGPR fertilizers individually had a significant effect on soil available phosphorus and increased the amounts of this element. The results indicated a better effect of vermicompost fertilizer, compared with humic acid fertilizer and PGPR in chickpea plants. The negative effects of PGPR may related to dryland farming conditions.
