Oyster Mushroom (Pleurotus ostreatus) Cultivation Using Sawdust and Different Organic Manures

Aims: The aim was to evaluate the performance of cultivating oyster mushroom (Pleurotus ostreatus) using sawdust and different organic manures. 
 Study Design: experimental design used complete randomized (CRD) Data obtained subjected Analysis Variance (ANOVA) followed by Turkey’s Least Significant Difference(LSD) test compare treatment means; differences considered significant at 95% (P≤0.05) (SPSS Version 21 software).
 Place Duration Study: National Biotechnology Development Agency, South East Center, University Nigeria, Nsukka between September 2019 November 2019.
 Methodology: Saw dust prepared as substrate with manures coded SD, dust; SDP, Sawdust+ Poultry; SDC, + cow dung; SDD, dust+ pig dung) in ratio 100:0 50:50 respectively cultivate ostreatus). Subsequently, rate growth, time harvest, yield average weight were recorded proximate composition determined standard methods.
 Results: Oyster harvested showed Moisture content ranged (4.63-7.14%), ash (4.84-6.77%), crude fat (0.98-3.28%), fiber (16.02-18.23%), protein (19.27-33.41%) carbohydrate (38.18%-48.89%). Average highest saw (10.2g) total (980g) least (7.5g) (105g) poultry litters substrate. from all differed significantly (p<0.05).
 Conclusion: Sawdust most suitable for cultivation though dung combination can be a good alternative.
