Field Efficacy of Trichoderma harzianum and Rhizobium against Wilt Complex of Chickpea

The experiment was conducted at farmer’s fields of Village Nawgaon, Block- Bilha, Dist- Bilaspur (Chhattisgarh), India. The study was performed under assured irrigated condition of upland in paddy-chickpea-paddy cropping system. Studies focused on the efficacy of bio-control agents at natural field condition through evaluation and demonstration leads to maximum productivity of chickpea. The seed treated with Trichoderma harzianum + Rhizobium along with soil application of T. harzianum enriched FYM found most effective to reduce the incidence of wilt complex of chickpea. The same treatment combination was superior in case of root nodulation, fresh wet and dry wet of chick pea plants. Maximum yield obtained 8.44 q/ha in treatment (seed treatment of T. harzianum + Rhizobium along with soil application of T. harzianum enriched FYM) followed by Seed Treatment by T. harzianum+ Rhizobium (7.57q/ha). Integrated Disease Management (IDM) approach was carried out to combat chickpea wilt with a combination of bio agents and organic amendments. Soil application of bio agents enriched with FYM proved additive effect over the seed treatments.
