Evaluation of different agricultural based substrate for mass multiplication of Trichoderma viride.

摘要

Studies were conducted to determine the colonization capacity of Trichoderma viride on various agricultural byproducts. The treatments comprised rice husk, rice bran, wheat bran, undersized sorghum grains and sawdust alone and in combination. Results showed that rice bran, rice husk and sawdust when mixed with sorghum in a 1:1 ratio supported excellent growth and sporulation of T. viride. Sorghum alone was equally effective for the growth and sporulation of T. viride. Maximum spore concentration was observed in sorghum powder, followed by the rice husk and sorghum and sawdust and sorghum mixtures. The spore production capacity was also high in rice bran, followed by wheat bran. The colonization and sporulation capacity of rice bran and wheat bran increased when both were mixed together.
