Patsan stem sticks, A promising substrate for cultivation of Pleurotus sajor-caju (Fr.) Sing.

Patsan stem sticks were used as the substrate for the cultivation of Pleurotus sajor-caju during beginning of January to middle February in 1990. The sterilization of water soaked of one foot long bare patsan stem stocks was done at 60-70°C for one and half hours and these were spread over the sterilized cemented floor for one hour to drain off excess of adhered water. The sowing was done in polythene bags (60X45 cm) with freshly prepared spawn on the boiled wheat grain in inter-spaces of the stem sticks and in this way one kg of substrate was mixed with 40 gm of wheat spawn. Ten replicates of such bags were made which were incubated till the appearance of sporophore primordia. The bags were removed after 6 days of sowing and compact bundle of substrate was watered daily in the evening. During experimentation the temperature ranged between 15.5-20.5°C and relative humidity varied between 70-80 per cent. The picking of the mushroom was done at regular interval of 5 days after the removal of bags from the substrate and the yield calculated was 1.15 kg/kg of dry substrate.
