Abstract

Four different organic substrates, viz., decomposed coir pith, dried cow dung, rice bran and tea waste, were tested tor the growth of Trichoderma viride (isolate t). The population (CFU) of T. viride on various substrates was estimated at 20^th, 30^th, 40^th and 60^th day after inoculation by serial dilution plate technique. The population of T. viride was highest on 20^th day in sterilized tea waste (236.30 í— 10⁶ cfu), followed by rice bran (152 í— 10⁶ cfu), decomposed coir pith (44.35 í— 10⁶ cfu), talc (36 í— 10⁶ cfu) and dried cow dung (20 í— 10⁶ cfu). Sterilized substrate was favourable for the multiplication of T. viride except for dried cow dung. The population increased in all the substrates except talc on 30^th day and declined from 40^th day onwards.
