IMPACT OF DIFFERENT NUTRITIVE SUBSTRATES ON THE PRODUCTION OF OYSTER MUSHROOM

Mushroom cultivation is a valuable method for bio-conservation in the agriculture trade. For the quality production of mushrooms, we used the agricultural waste material as a substrate, and after harvesting, this substrate is obtainable as an excellent soil conditioner. In this study, we used the sawdust of simbal tree (Bombax ceiba L.), office scrap paper and poultry manure as a substrate to cultivate the Pleurotus sapidus (oyster mushroom). Data recorded from inoculation of spawn to the harvesting of fruiting bodies by using different parameters. The results revealed that the Treatment-T4 (sawdust of simbal tree 50% + poultry manure 50%) required the least number of days for spawn-running, development of pinhead and fruiting bodies, produced maximum number of fruiting bodies, maximum yield and highest biological efficacy. The Treatment-T5 (office scrap paper 50% + poultry manure 50%) took the maximum number of days for spawn-running, development of pinhead and fruiting bodies, produced least number of fruiting bodies, minimum yield, and lowest biological efficacy. Therefore, the cultivation of mushrooms is an excellent or environment friendly technique because the substrate that used for mushroom cultivation is economical and readily available.
