The growth and post harvest performances of different species of oyster mushroom (Pleurotus sp.) cultivated on sawdust and oil palm frond
Oyster mushrooms (Pleurotus sp.) have more than 1000 species worldwide such as grey (Pleurotus sajor-caju), yellow (P. citrinopealatus), pink (P. flabellatus) and white (P. florida) which are cultivated on various agricultural wastes. In this study, the growth performance, yield and postharvest qu...

| Summary: | Oyster mushrooms (Pleurotus sp.) have more than 1000 species worldwide such as grey (Pleurotus sajor-caju), yellow (P.
citrinopealatus), pink (P. flabellatus) and white (P. florida) which are cultivated on various agricultural wastes. In this study,
the growth performance, yield and postharvest quality of different species of oyster mushroom cultivated on sawdust and oil
palm frond (OPF) were determined. Sawdust and OPF in combination with rice bran and calcium carbonate in 100:10:1 ratio
respectively was used as substrates. The growth performance in terms of mycelium growth, days for mycelium to fill up the
bag, pinhead emergence and fruiting body formation were measured. The postharvest qualities studied involved color, texture,
moisture, ash, protein and crude fiber contents. Yellow oyster mushroom on OPF took the shortest time for mycelium growth,
mycelium fill up the bag, pinhead emergence and fruiting body formation. However, oyster mushrooms cultivated on sawdust
had higher biological efficiency (29.34 to 60.76%) as compared to on OPF (21.49 to 45.08%). White oyster mushroom had
the highest biological efficiency followed by yellow, grey and pink. Meanwhile, grey oyster mushroom showed darker color
compared to other oyster mushroom species. OPF used as substrates provide brighter yellow and pink color in yellow and
pink oyster mushrooms respectively and greater in firmness especially for pink oyster mushroom. There was no significant
difference (P>0.05) found in chemical properties of different oyster mushroom species cultivated on sawdust and OPF. In
conclusion, oyster mushrooms cultivated on sawdust produced better yield even though OPF gave better growth performance
and physical properties of color and firmness. |
