Two species of Trichoderma viz., T. harzianum and T. aureoviride isolated from rhizosphere of pigeon pea promoted plant growth. To understand the role of Trichoderma in growth promotion, the ability of Trichoderma spp in solubilizing rock phosphate was tested in vitro. Culture filtrates of both species solubilized rock phosphate. T. harzianumwas more effective than T. aureoviride in solubilizing phosphates and producing fungal biomass.
