Using organic matter, such as, peat and vermicompost as soil amendment, increases aeration, water infiltration, water holding capacity and nutrients of soil . A greenhouse experiment was performed to study the effect of organic materials on plant growth characteristics, total biomass and grain weight of chickpea with four treatments; 1) Soil + 3% peat (PS), 2) Sterile soil + 3% peat (SPS), 3) Soil + vermicompost (1:6) (VCS), 4) control (C) in a completely randomized design with four replications. The results showed that the maximum germination percentage, number of branch and number of pod per plant were observed in SPS treatment due to the avoidance of harmful microbial impacts. Plant height in this treatment reduced, whereas, no significant differences in total dry matter per plant and dry weight of chickpea per plant were observed compared to control. Plant growth consist of plant height, number of branch and number of pod per plant in vermicompost and soil + peat treatment reduced in the early stages probably because of plant - microbes interaction effects. Application of vermicompost increased fresh and dry weight, pod dry weight and single grain weight, probably due to more plant nutrient availability in this treatment when compared with other treatments.
