Among the carbon sources, glucose supported highest weight of dried mycelium and maximum number of sclerotia formation followed by sucrose and maltose. The lactose supported least growth and also inhibitory for sclerotia formation. Out of four nitrogen sources, calcium nitrate supported highest weight of dried mycelium and maximum number of sclerotia followed by alanine. Urea exhibited inhibitory effect for sclerotia formation. In the vitamins, Thiamine supported highest weight of dried mycelium and maximum number of sclerotia followed by yeast extract. Biotin and inositol both were found to be inhibitory for growth and sclerotia formation as well. Combinations of fructose + glucose + lactose and sucrose + fructose + lactose resulted in such a highest level of growth and sclerotia formation. The combination of sucrose, fructose and glucose found to be inhibitory for growth and sclerotia formation both. Among the combinations of nitrogen sources, calcium nitrate + alanine + sodium nitrate supported highest growth and sclerotia formation followed by calcium nitrate + urea+ alanine+ sodium nitrate. It was interesting to note that addition of urea in any combination had an inhibitory effect on growth and sclerotia formation. Among the combinations of vitamins; biotin + calcium pentothenate + thiamine resulted in highest growth, whereas highest sclerotia formation was noticed in yeast extract (multivitamins) supplemented medium. Biotin, thiamine and calcium pentothenate stimulated the mycelial growth, but addition of inositol was found to be inhibitory to the fungal growth and sclerotia formation.
