Effects of different levels of wheat bran, rice bran and maize powder supplementation with saw dust on the production of shiitake mushroom (Lentinus edodes (Berk.)‎ Singer)‎

Abstract EN

The cultivation of shiitake mushroom (Lentinus edodes) is increasing rapidly in Bangladesh due to its nutritional and medicinal importance with excellent flavor and longer shelf life.

With the aim of increased production, we have cultivated L.

edodes on saw dust (SD) supplemented with different levels (10 %, 15 %, 20 %, 25 %, 30 %, 35 % and 40 %) of wheat bran (WB), rice bran (RB), maize powder (MP) and their combination (WB + RB + MP = 1 : 1 : 1) to investigate the growth, yield and quality of this mushroom.

Most of the growth, yield and quality parameters varied significantly when mushrooms were cultivated with different levels of supplementation.

The yield of mushroom was increased with the level of each supplementation upto a certain level, and then decreased.

SD supplemented with 25 % WB produced the highest number of fruiting bodies (34.8 / 500 g packet), highest biological yield (153.3 / 500 g packet) and biological efficiency (76.6 %) of L.

edodes.

But the yield of the best quality mushroom was observed on SD with 40 % WB supplementation ; however, the qualities were not always supplementation dose dependent.

In this study, we report that 25 % WB supplementation with SD may be very effective for higher yield and 40 % WB supplementation for better quality of L.

edodes.
