Cultivation of oyster mushrooms (Pleurotus ostreatus) is suitable in Batticaloa district. The sawdust + paddy straw and sawdust + shredded paper substrate are the suitable and efficient substrates. The sawdust + paddy straw is the substrate with efficient production. The sawdust + paddy straw substrate took the shortest time for production.
Further studies should be carried out by using the substrate after the fermentation of the raw materials for 1-2 days. The studies should be needed by using other materials such as maize leaves, corn cobs, sugarcane leaves, rice bran …etc. The studies should be needed to find out the effect of various grain spawns.
