how to increase oyster mushroom yield

If you are wondering how to increase oyster mushroom yield, read on! Growing oyster mushrooms in your own garden is possible, but you must follow a few simple steps to make your harvest a success. In the wild, oyster mushrooms will grow in response to changes in their environment and stress. These changes will affect the mushroom’s growth and the quality of the end product. Learn how to increase oyster mushroom yield by using a variety of composted straw materials.

Composted straw materials

Composted straw materials increase oyster mushroom yield by up to fivefold. These materials are moist and can be fermented by submerging them in water. This method will require two weeks and will kill any oxygen-dependent organisms. Then, the straw must be cooled before using. Ideally, the temperature should be around 75degF. During the heat treatment, the straw should be placed in water penetrating bags and sealed with zip ties. Then, the bag should be submerged in a water temperature of 160degF. Bricks or other weights should also be placed on top of the bag.

Cotton seed hull

The use of cotton seed hull in the cultivation of oyster mushrooms has been shown to increase their yield by as much as ten-fold. However, this technique is not appropriate for all circumstances, as it can cause adverse effects on the health of mushroom-farmers. Aside from this, cotton seed hull can also be used as a cover crop to increase yield. This method is beneficial for both large and small-scale mushroom farmers because it has multiple benefits for the health of the plant.

Rice straw

In the present study, the inclusion of rice straw increased oyster mushroom yields. Rice straw was a by-product of agriculture and was used to replace gypsum in the cultivation medium. The studies were carried out in a greenhouse, the Mushroom Res. Farm, and the Protected Cultivation Center. The addition of waste materials was adapted by soaking them in hot water. Nevertheless, the results of the experiment have not been fully substantiated.

Wheat straw

Increasing the amount of wheat straw used for cultivation can increase the oyster mushroom yield by a factor of two. In a recent study, wheat straw significantly increased yield and growth rate when used as substrate instead of cotton seed hull or rice bran. However, the effect on the yield was diminished when the straw was ground too finely. This article describes the process used to increase oyster mushroom yield using wheat straw. Read on to learn more.


The use of gypsum in a farming technique for increasing oyster mushroom yield is not new. However, the results from experiments conducted with different materials and methods have varied considerably. Cotton seed, lime, gypsum, and cotton waste are all acceptable substrates for growing oyster mushrooms. But, paper wastes contain lower BE than cotton seed. In addition, they may need additional nitrogen, phosphate, and potassium to grow the mushrooms.


A nutritional supplement can be a valuable addition to oyster mushroom cultivation. The cap of an oyster mushroom is considered a vegetable. It contains significant levels of B vitamins, C vitamins, minerals, and very little fat. The inclusion of legumes in the diet can significantly increase yield. Other materials to consider as a supplement include coffee grounds, rice bran, peanut shell, and straw. A study published in The Journal of Food Science and Technology recently identified soya cake powder as an ideal supplement for oyster mushrooms.

Gypsum supplementation

Increasing oyster mushroom yield can be a simple matter if you have the right nutrients. Various additives are effective at stimulating fungal mycelium expansion and proliferation. However, different additives have different effects. In this study, we investigated whether gypsum and lime supplementation can enhance oyster fruiting and spawn production. The following information may be helpful in increasing oyster mushroom yield. Before starting your oyster mushroom cultivation, make sure your substrate is pasteurized and cooled.

Increasing spawn:bulk substrate ratio

Increasing spawn:bulk substrate ratio in oyster mushroom cultivation has been shown to increase yield significantly. This study involved the use of different agro-wastes as a spawn substrate in a two-phase composting process. The spawn and bulk substrates should be prepared according to the growth stages of each species. The first composting phase should be done with equal proportions of rye grain and water. The second composting phase should be completed after harvesting.

Cost effective agro-industrial by-products

The use of agricultural and industrial wastes to increase oyster mushroom yield has recently received world attention. Agro-industrial wastes such as rice bran, wheat straw, and cotton seed cake were all tested as potential substrates in a laboratory setting. The results of the experiments revealed that substrates with higher lignin and cellulose content increased yields. However, there are several drawbacks to using agro-industrial by-products for mushroom cultivation.

Increasing yield of oyster mushrooms

Growing oyster mushrooms can be profitable if you know how to maximize their potential. Oyster mushrooms are edible and a byproduct of agriculture. Several factors affect their growth and yield. The substrate, for example, affects the length of the mycelium’s running time, the number of fruit bodies produced, and the size of the primordial diameter. Increasing yield of oyster mushrooms can be done by experimenting with different substrates.
