Mushroom Farming In Nigeria | Image Source:

Mushrooms, a member of the fungus family; rich in protein, Vitamin B, and minerals, are edible cash crops with a large global demand. Their cultivation, which is not just fuelled by their various uses in staple meals, is also largely motivated by their wide medicinal uses, and as such, are cultivated and sold commercially in over 60 countries including Nigeria, The United States, France, Poland, Netherlands, and a host of other countries.

The biological makeup and fast growth rate (usually 3 weeks) of edible mushrooms, also scientifically known as Agrodok, makes them a choice crop for a small sect of farmers with a wide supply chain network. They can also be cultivated domestically or picked in the wild, with some growing above the ground and others growing below the ground.

What Is Mushroom Farming About?

Mushroom farming is the cultivation and commercial sale of edible mushrooms for food and medicinal purposes; either on decaying organic matter like tree trunks or on soils through the six farming steps namely: making the mushroom compost, finishing the compost, spawning, casing, pinning, and cropping. Their cultivation makes it possible for commercialisation and other benefits their nutritional and medicinal value adds.


Business Opportunities In Mushroom Farming Around The World

1). A Source Of Food: 

Mushrooms as a source of food

Mushrooms as a source of food

Mushrooms are used as a source of food in many parts of the word, because they’re rich in protein (6%), dietary fibre (4%), low carbohydrates (1%), low calories (1%), riboflavin (24%), niacin (10%), pantothenic acid (15%), Vitamin D (5%), Copper (16%), Selenium (13%), Phosphorus (9%), and Potassium (9%).

Mushroom farmers growing the crop as a source of food can hone in on the international demand potential of this product and export them to countries like Zimbabwe, Tanzania, The United States, Netherlands, Poland, France, and several other countries.

2). Medicinal Purposes: 

Mushrooms As Medicine

Mushrooms As Medicine

Mushrooms are consumed worldwide, because of their health benefits. Some of their medicinal advantages includes protecting diabetic patients from infections, lowers cholesterol levels, prevents breast and prostate cancer, improves bone health, boosts the immune system, reduces blood pressure, stimulates the absorption of iron, aids in weight loss, amongst several others.

Their use creates opportunities in the health care industry, thereby building an income stream for mushroom farmers through the constant supply of mushrooms to drug manufacturers and people who need the mushrooms directly.

Setting Up Your Mushroom Farm

Step 1: Making Mushroom Compost 

Making Mushroom Compost

Making Mushroom Compost

This phase occurs in an enclosed structure with a roof-top. A wharf, also referred to as a concrete slab, is important for this compost step along with a compost turner, which is used to water and aerate the ingredients, and a tractor-loader, which is used to move the ingredients to the turner.

If you don’t have a mechanized equipment for this phase, you can turn the piles by hand using pitchforks. You then start by wetting and mixing the ingredients while they’re stacked in a rectangular pile and have a loose centre and tight sides.

This phase 1 process would last from 7 to 14 days, which could vary based on the nature of the material used at the beginning and its characteristics at every turn. The composting process is then mostly accompanied with an ammonia odour, which follows with a mouldy and sweet smell.

While there are several more steps to go in this initial phase, when the required colour, temperature, odour, and the moisture is achieved, the process of making the mushroom compost is complete.

Step 2: Finishing The Compost 

Finishing The Mushroom Compost

Finishing The Mushroom Compost

This phase is largely carried out for two primary purposes. The first is to kill pest fungi, insects, nematodes, and other pests that may be living in the compost through a process called pasteurisation. The second purpose is to eliminate all forms of ammonia generated during the phase 1 process of making the mushroom compost.

It is critical that the ammonia be removed because if its remains. At the end of the phase 2 process of finishing the compost, its concentration would be higher than 0.07% and can be lethal to the mushroom’s growth in the spawning process.

The phase 2’s end is usually accompanied with a lowering of the compost temperature to 75 degrees to 80 degrees Fahrenheit before the spawning process can begin.

Stage 3: Spawning 

Spawning Mushrooms

Spawning Mushrooms

In this phase, the mushroom compost is introduced with mushroom spawn for the mushroom to grow. Just as certain plants like tomatoes are the fruits of a tomato plant, mushrooms themselves are equally the fruit of a plant. Inside every tomato, we’d find seeds which are used to grow the next set of the tomatoes. In the mushrooms too, we’d find some microscopic spores inside the mushroom cap. But due to the nature of their tiny size, they cannot be handled like regular seeds.

The spawning process can begin by sterilizing a mixture of chalk, water, millets, wheat, and other tiny grains which could substitute perfectly for rye grain.

After the compost and the spawn have been mixed together, whether by hand or by a bed system, the compost temperature should be settled around 75 degrees Fahrenheit.

The spawn process would run for 14 to 21 days, and the moment the compost has  fully grown with the spawn, the next phase is then carried out.

Stage 4: Casing 

Casing Mushrooms

Casing Mushrooms

At this phase, the casing, which is a form of dressing, is applied to the top of the spawn compost, which the mushrooms eventually form on. Here, a mixture of ground limestone with peat moss or clay-loam field soil can be used as the casing on the compost.

To manage the crop after casing, it needs to be kept at 75 degrees Fahrenheit for 5 days with a high relative humidity. After this, the temperature of the compost should be reduced to 2 degrees Fahrenheit everyday until tiny mushroom pins have been formed.

Phase 5: Pinning 

Pinning Mushrooms

Pinning Mushrooms

The pinning phase occurs when the mushroom initials form after the rhizomorphs have developed in the casing. Once the initials grows to about four times its size, it becomes a pin. During the button stage, the pins continue to increase and expand till the button eventually becomes a mushroom.

The mushrooms can now be harvested between 18 to 21 days after the casing.


Phase 6: Cropping 

Cropping Mushrooms

Cropping Mushrooms

In the cropping cycle, the bloom, which is the 3 to 5 days repetitive harvesting period, is carried out with breaks on days when there are no mushrooms to harvest. This cycle continues in an endless spiral until there are absolutely no mushrooms to harvest anymore. The average time most farmers spend harvesting the mushrooms is usually 35 to 42 days. Although some farmers spend as much as 60 days, on rare occasions, few farmers may continue harvesting for up to 140 days.

When the final mushrooms have been harvested, the room used to groom the mushrooms would then be closed off and pasteurised with steam. This process is important, because it ensures that no pests are left alive on the crops or the woods in the mushroom grooming room. Thereby, reducing the chances of an infestation on the next round.

The cropping process brings to an end the 15 weeks mushroom production cycle, which ranges from creating the mushroom compost to the final steaming stage after the mushroom harvest is complete.

At this point, the average weights of the mushrooms would be about 0 to 4 lbs per square foot. For a healthier larger yield, the grower must be carefully monitored, with the temperature, humidity, and pests highly controlled.
