To evaluate the effect of sawdust (SD) and rice straw (RS) on yield of different strains of Pleurotus cystidiosus (PCYS1-5), various yield attributes were measured in the present experiment. Among them, the best effect had been observed in the case of PCYS2. The highest mycelial running rate was observed in PCYS-2 + SD (0.84 cm). The highest average number of fruiting body/packet was observed in the treatment PCYS-2 +SD (61.00), followed by PCYS-1 +SD (58.00), PCYS-2 +RS (58.00) and the lowest in the treatment PCYS-3 +RS (47.00). The highest biological yield was observed in PCYS-2 + SD (255.6 g) and the lowest in PCYS-1 + RS (193.7 g). PCYS-2 + SD also showed the highest biological (255.6 g) and economic yield (188.3 g), the dry yield (25.02 g) and the highest biological efficiency of (85.20%). However, the highest cost benefit ratio was calculated in treatment PCYS-3 + RS (7.69) and the lowest cost benefit ratio 6.34 was calculated for PCYS-3 + SD and PCYS-4 + RS. Thus, saw dust stands out as the better substrate and the PCYS-2 as the best strain in the present experiment.
