Abstract
Background: Chickpea is an important legume crop, which is susceptible to various biotic stresses. Wilt disease severely affect chickpea crop and cause substantial yield reduction. Trichoderma species is a prominent bio-control agent, which is applied against soil borne pathogens. Trichoderma spp. is available in the market in different formulations. The present study investigated the efficacy of a novel Trichoderma viride based seed biopriming method against wilt causing pathogen (Fusarium oxysporum f. sp. ciceri) in chickpea crop. Methods: The experiment was conducted in-vitro and in-vivo for two years to assess the effect of different doses of T.viride based bioformulation on chickpea seed quality parameters, plant survival against wilt pathogen and chickpea seed yield. Result: Significantly chickpea plants survived (68.71%) against the impact of wilt pathogen when seeds were bioprimed with T. viride bio-formulation @ 5 g/kg seeds. In contrast, only 51.78% chickpea plants survived from untreated seeds. Comparatively high chickpea yield (7.23 q/ha) was produced from bioprimed seeds than untreated seeds (4.65 q/ha). Bio-formation of T. viride (@ 5 g/kg seeds-based seed biopriming is an eco-friendly method to overcome notorious wilt pathogen that lessen the disease incidence and improves the seed quality traits and maximizes the seed yield.
