In Haryana condition, studies carried on cultivation of G. lucidum during 2013 and 2014, a combination of wheat straw+saw dust (1 : 1), having a 20% dosage of wheat bran as supplement and amended with calcium sulphate (3%) and calcium carbonate (1%), was filled in polypropylene bags, plugged, sterilized and inoculated with wheat grains based spawn @ 3%. The bags were placed in mushroom house at 30±1?C with 90±1% relative humidity. During cultivation, mould incidence was less in supplemented substrate (10.00%) as compared to un-supplemented (14.00%) substrate for two consecutive years which resulted in lowering down the biological efficiency from 27.52 to 20.18%, respectively.
Key words :Ganoderma lucidum, substrates, mould, biological efficiency
