Cultivation of different strains of king oyster mushroom (Pleurotus eryngii)‎ on saw dust and rice straw in Bangladesh

Abstract EN

Pleurotus eryngii is a popular mushroom due to its excellent consistency of cap and stem, culinary qualities and longer shelf life.

In Bangladesh, where Pleurotus mushrooms are very popular, P.

eryngii may take position among the consumers, but currently this mushroom is not cultivated in large scale there.

In this study, 3 strains of P.

eryngii such as Pe-1 (native to Bangladesh), Pe-2 (germplasm collected from China) and Pe-3 (germplasm collected from Japan) were cultivated on saw dust and rice straw and their growth and yield parameters were investigated.

Pe-1 on saw dust showed the highest biological yield and efficiency (73.5 %) than other strains.

Also, the mycelium run rate and number of fruiting bodies were higher in Pe-1 than other two strains.

The quality of mushroom strains was near about similar.

On saw dust, the yield and efficiency were better than those cultivated on rice straw, however, on straw ; the mushroom fruiting bodies were larger in size.

This study shows the prospects of P.

eryngii cultivation in Bangladesh and suggests further study in controlled environment for higher yield and production.
