Cultivation of Pleurotus ostreatus on Agricultural Wastes and Their Combination

Background. Mushrooms are increasingly becoming an important component of diets worldwide, and it is paramount importance to choose appropriate substrates grow them. The objective this study was Pleurotus ostreatus mushroom using different agricultural substrates. Methods. Corncobs, finger millet straw, bamboo waste were collected from sites the Awi Zone. chopped into small pieces, 500 g their dry mass alone combination measured, packed in a polythene bag, moistened, pasteurized. cooled inoculated with spoon P. spawn brought Debre Berhan University. bags placed growing room, growth parameters recorded continuously environmental variables. experimental setup complete randomized design, six treatments three replicates. Results. fastest running phase 28.71 ± 0.80 days, pinhead formation 32.36 0.26 fruiting bodies’ 5.19 0.74 days after on corncob substrate. highest fresh weight biological efficiency significant statistical association obtained grown straw (253.07 1.05 50.20 0.47, respectively). average number pinheads bodies (29.60 11.44, respectively) straw. lowest (20.80 0.41), (101.48 0.91), (14.40), (4.25) mixture (50% each) Conclusion. Finger recommended as best substrate for cultivation ostreatus. mixed (1 : 1) not encouraged due poor performance.
