Antagonistic bacteria, Bacillus subtilis (B-120 from chickpea fields in Karaj, B-22 from chickpea fields in Saeen-ghale, B-28 from soybean field in Gorgan and B-32 from bean fields in Varamin) and Pseudomonas fluorescenes (Pf-100 and Pf-19 from chickpea fields in Karaj and CHAO from Plant Pathology Department, Plant Science Institute of Zurich Polytechnique University) were used to control Fusarium wilt in chickpea.The experiment was carried out in a completely randomized design in pot under greenhouse conditions.The results indicated that only B-120 isolate significantly reduced Fusarium wilt in chickpea, with the rest having positive effect on growth factors in chickpea. In infested soil, antagonistic bacteria exhibited a significant positive effect on plant growth factors. B-120, B-28, and B-32(B. subtilis) as well as Pf-100 (P. fluorescens) isolates caused an increase in growth factors including dry & fresh root & shoot weights, plant height as well as root length as compared with those in control.
