Substrates affect the yield and quality of oyster mushroom

Mushrooms belong to the kingdom of fungi, a group, very distinct from plants, animals and bacteria. They lack the most important features of plants – the ability to use energy from the sun directly through chlorophyll. Thus, fungi depend on other organisms for food, absorbing food from the organic materials in which they live. Mushroom cultivation creates job opportunities for many people around the world and equally create avenue of utilizing agricultural waste materials. Commercial cultivation and processing of mushroom requires a good knowledge of the growth requirements, and influence of the substrate on their growth rate and nutritional composition. Many researches have already reported that the yield and the quality of oyster mushroom depend on the chemical and nutritional content of substrates.

Substrates affect mushroom yield

Commonly, substrates affect mushroom yield. The substrates influence the duration of mycelium running, pin head formation, number of fruit bodies produced, the cropping time, the pileus diameter (size of cap), and the biological efficiency of oyster mushroom. The mycelium running can take 3 to 4 weeks after inoculation (1kg wet substrate). The pin-head (the second stage of mycelial growth during cultivation of mushroom) can be observed 6 to 10 days after the bags are opened. The first flush can be harvested after 41-52 days cultivation on wheat straw substrate. Generally, yield of mushroom will be decreased in consecutive flushes due to the nutritious limitation of substrate. Substrates can be tailored to achieve desired mushroom yield and nutrient profile.

Sieni-Talo mini kit from Sietalab was conducting various tests to check the effects of substrates on the yield and quality of grey oyster mushroom. The mushroom kit will give at least three flushes with high quality and appearance. The products not only bring to people the understanding about the micro world of mushroom’s growth and development but also discover an own world for hobby and relaxing.
