Abstract
Population of T.harzianum after multiplication on different substrates viz., rice grain, sorghum grain, millet grain and saw dust was determined at 0 day and after 15, 30, 60,90 and 180 days of storage. Growth of T.harzinum increased with the increase in time on sorghum grain, rice and millet grains, while saw dust was not suitable substrate for the multiplication of T. harzianum. The inoculum multiplied and stored in plastic bags remained viable for up to 180 days at room temperature. Soil amendment with T. harzianum after multiplication on rice, millet and sorghum showed significant increase in height and weight of mash bean and chick pea plants, and significantly reduced the infection of Macrophomina phaseolina, Rhizoctonia solani and Fusarium spp. at different storage intervals on chick pea and mash bean. T.harzianum after multiplication on sorghum grain reduced the infection of M.phaseolina whereas inoculum on rice grain reduced the infection of Fusarium spp. R.solani infection was completely inhibited by T.harzianum multiplied on rice, sorghum and millet after 15, 30, 60 and 90 days of storage.
