Influence of Trichoderma viride on performance of chick pea in Wilt complex area

Field trial was conducted in order to evaluate promising isolates of Trichoderma viride as biocontrol agent for wilt complex fungi (Fusarium, Sclerotium & Rhizoctonia). Four selected local isolates of Trichoderma viride were compared with three national checks. Lanthyrus local Rhizobium isolate L-4 was also included in the study as bio-control agent for wilt fungi (Fusarium). Keeping in view of observations related to plant height, plant population, nodulation, wilt incidence and biomass accumulation, performance of T. viride local isolate 2 was found superior followed by T. viride national check isolate for increasing chick pea -Rhizobium symbiosis. At farmer's field, about 83 % higher grain yield of chick pea was recorded by the dual inoculation of T. viride local isolate 2 with Rhizobium over single inoculation of Rhizobium in the wilt complex affected area. While, maximum straw to grain ratio was recorded in uninoculated unfertilized control plot.
