Trichoderma is an ecofriendly, soil-borne fungus found ubiquitously in soil and known to be a potential biocontrol and growth-promoting agent. Bio prospection of native Trichoderma spp. is a promising research area that encourages organic farming culture and the withdrawal of dependency on chemical pesticides. The adoption of organic crop production reduces health hazards in various sustainable ways. In the present investigation, the in vivo effect of native Trichoderma spp. was studied on the growth and yield of some vegetable crops, i.e., cabbage, cauliflower, pea. During the crop season of 2017-18, 3 native isolates of Trichoderma, namely Trichoderma asperellum-7 (KU933475), Trichoderma asperellum-25 (KT601340), Trichoderma harzianum-69(KU933468), along with a commercial formulation of Trichoderma viridi, were evaluated for its effect. The native Trichoderma and a commercial Trichoderma formulation were treated individually. A consortium treatment of the native Trichoderma was assessed for their performance in terms of plant growth & yield against control (only compost and FYM). The different treatments of Trichoderma spp. were influenced growth parameters and yield attributes on the vegetables studied. It was found out that the performance in terms of yield was highest in the consortium treatment of the native Trichoderma in all of the crops studied. Hence, the application of native Trichoderma improves the quality of the products and thereby increases crop yield.
