This investigation estimated the interaction effects of oyster mushroom species, cultivation location, and local lignocellulosic substrates on composition of Pleurotus fruiting bodies carbon, nitrogen, macro-mineral and biological efficiency (BE), Pleurotus citrinopileatus, P. djamor, and P. pulmonarius were growing under laboratory and greenhouse conditions on wheat straw, sawdust-based substrate, wood chips–sawdust blend, straw-based substrate, and rice straw. (BE) and fruiting-body C, N, Ca, Na, K, and Mg concentration were measurements and statistically analyzed using factorial comparisons with LSD at P ≤ 0.05. The results showed that the P. pulmonarius is the highest BE (87.84%) and 3.29% nitrogen and 43.87% carbon content. The condition in laboratory under 25 C^o increased the overall the BE and carbon content, though wheat straw given the highest means BE 61.71% and rice straw the uppermost nitrogen content (3.32%). The highest carbon contents were in the wood chips–sawdust blend 45.41%, while the Calcium and Potassium showed no significant differences in main factors oyster strain genotypes, locations and substrates.  P. pulmonarius had the highest sodium content, whereas P. djamor recorded the highest magnesium content. Overall, species–substrate–location interactions strongly influenced productivity and selected mineral traits, highlighting the importance of matching fungal genotype with cultivation environment and locally available substrates.
