Management of stem rot of groundnut (Arachis hypogea L.) using organic amendments and Trichoderma viride

Groundnut is a major legume and important oil seed crop belongs to family Fabaceae. A large number of diseases attack groundnut plant in India, of these stem rot caused by Sclerotium rolfsii is the most common disease. The present study was conducted in experimental field of SHUATS for management of stem rot disease of groundnut (Sclerotium rolfsii) which is most important destructive disease of groundnut in India. Therefore present studies were undertaken to test Trichoderma viride, Neem cake, vermicompost and the combinations along with the treated check (Vitavax). In in vitro conditions Trichoderma viride + Vermicompost + Neem cake significantly reduce the disease incidence of Stem rot (15.53%) as compared to treated check with (12.27%) and control (54.4%) and also maximum shoot length (54.60), root length (29.47), dry weight of plants (19.47), dry weight of roots (1.53), pod yield of plants (12.16), kernel yield of plants (7.98) was observed in Trichoderma viride + Neem cake + Vermicompost. In in vivo conditions highest growth inhibition was observed in treated check (89.29%) followed by Trichoderma viride (60.15%) and Neem cake (28.66%). | Management of stem rot of groundnut (Arachis hypogea L.) using organic amendments and Trichoderma viride
