ABSTRACT
The present investigations entitled “Studies on cultivation of Pleurotus djamor” was
undertaken to understand the spawn production, cultivation technology and the cultural
requirements of the test fungus. For spawn production, kodo grain spawn was found as best
substrate but maximum biological efficiency was obtained by using wheat grain spawn. For
cultivation, best yield was recorded using 5% spawn dose on wheat straw substrate. Lantana
gave good yield when used as a substrate for the cultivation of Pleurotus djamor. Good yield
and biological efficiency was obtained when wheat straw was supplemented with wheat bran
in the ratio of 9:1. Different solid media were tried for maintaining the pure cultures and
MEA and PDA were found to support maximum radial growth. In case of various liquid
media, Glucose-asparagine solution was found to support maximum mycelial growth of P.
djamor. An optimum temperature of 250C and pH in acidic (5.5) and slightly acidic (6.0)
range were found to be preferred by this fungus. Maltose was recorded as good carbon
source. In case of nitrogen sources, potassium nitrate supported good growth. Among growth
regulators viz., giberrellic acid supported best mycelial growth of the test fungus. Maximum
radial growth of the fungus was observed under exposure of 6h light and 18h dark period.
