Fruiting bodies yield of oyster mushroom (Pleurotus columbinus) as affected by different portions of compost in the substrate

Abstract

Purpose A study was conducted to assess production of Pleurotus columbinus mushroom fruiting bodies for different formulations of rice or corn straw substrates mixed at different percent portions with the corresponding composted straw. Methods These formulations were: (1) raw straw (RS) mixed with 5 % composted straw (CS), (2) RS mixed with 10 % CS, (3) RS mixed with 15 % CS, (4) RS mixed with 25 % CS, (5) RS mixed with 50 % CS, and (6) 100 % RS. Composted straw (CS) was made of moistened chopped RS mixed with chicken manure and soil (4:1:1, v/v). Results Data showed a magnificent impact of the substrate on oyster mushroom fruiting bodies yield and characteristics. There was a significant progressive upgrading in all parameters studied of mushroom growth and crop outcome with increasing the percentage of CS mixed with the RS substrate up to 15 %. Utilizing CS at 25 % significantly downgraded these parameters. No mushroom growth was observed at all when cultivated in medium contained 50 % CS. Instead, molds of different colors grew on that latter substrate mixture. The formulation containing 15 % CS distinctly gave the uppermost fruiting bodies yield, biological efficiency, earliness for pinheads formation, fruiting body cap diameter, thickness and weight and stem diameter, length and weight. Up to 80 % increase in fruiting bodies crop outcome relative to sole RS was detected. Conclusions This study suggests that composted straw substrates hold a great promise for the development of Pleurotus mushroom production industry.

Cultivation of straw mushroom (Volvariella volvacea) on oil palm empty fruit bunch growth medium

“…Chang and Wasser (2017) state that the breakdown of raw ingredients by microorganisms in a fermentation process is more dynamic in a conducive environment. Mohamed et al (2016) state that in the fermentation process, microorganisms propagate and the nutritive substances of the substrate are accumulated in the form of protein and other useful compounds. Therefore, the effects of fertilizer supplement to the EFB substrate on improving the fermentation dynamics in this research was quite clear.…”

Recycling spent Pleurotus eryngii substrate supplemented with Tenebrio molitor feces for cultivation of Agrocybe chaxingu

“…The data indicated that to obtain good fruitbody yield the spent substrate should be replenished with the easily digestible ingredients like soluble sugar, starch and hemicellulose, but extra nitrogen source (e.g., soymeal), lignocellulosic ingredients were not required to be supplemented, hence wheat bran, cornmeal and T. molitor feces could satisfy this purpose. In fact, too much nitrogen in the substrate can lead to ammonia accumulation during storage or preparation which inhibited mycelial growth (Choi 2004;Mohamed et al 2016).…”

Upcycling of Oyster Mushroom Spent Through Reuse as Substrate in Sequential Production Cycles of Mushroom

“…This may be attributed to the mycelia content of mushroom remaining in the spent. It would need a bio-decomposing to be available for the current growing mushroom (Mohamed et al, 2016). Okhuoya et al (2000) reported that a well-balanced carbon to nitrogen ratio enhances the growth and development of mushroom while an imbalance of C/N impedes their growth.…”
