This study was conducted to assess the effect of nitrogen (N) variations from lignocellulosic substrates of empty fruit bunch (EFB), palm oil frond (POF), palm oil trunks (POT), A.mangium bark (AB) and Cogongrass (IC), and combinations among them using biological supplements (POF and POT) for suitability as a substrate of P. ostreatus. Three different sets of substrates were evaluated in response to different parameters of P. ostreatus including spawn running, primordial initiation, fruit body yield and biological efficiency (BE). The supplementation of POT and POF generally revealed significant differences on the crop performance of P. ostreatus compared to the un-supplemented substrate. POT demonstrated reduced production time, while POF was the best supplement to promote fresh weight and BE. The most rapid spawn running took place within 18.6 +/- A 0.9 days, while the primordial initiation was observed within 23.2 +/- A 0.5 days in the combination of IC + POT. The most suitable substrate for higher mushroom weight and BE was IC + POF (19.6 +/- A 1.3 g; 70.5 +/- A 5.5%). In addition, the interval between primordial formations was found to be fastest in the un-supplemented EFB and the combination of EFB + POF, which supported a shortened production time. Therefore, IC and EFB appeared to be the better alternative materials for growing P. ostreatus, either with or without any supplementation.
