Mushroom Growing Resources in Kenya

This is a highly disorganised collection of resources relating to mushroom growing and training in Kenya. If some of the information is out of date, it would help everybody if you leave a comment at the bottom. Also, if you know of a training course, perhaps you would also leave a comment.

The Agricultural Information Resource Centre (AIRC), Ministry of Agriculture, Kenya (email: published in 2009 a colour  booklet entitled ‘Guide to Growing Mushroom’. COSDEP grows oyster mushroom for sale and training purposes. They also sell mushroom substrate  to farmers. Being near to Nairobi which is the main market of this useful product is an added advantage. They also give mushroom production as a course to farmers upon arrangements.

Fully Certified Mushroom Growing Course

Due to public demand, the Jomo Kenyatta University of Agriculture and Technology has developed a comprehensive training programme at the University Campus for training in growing of the most popular mushrooms.

Course Dates for 2012:

  • OCT 24-26, NOV 21-23, DEC 05-07

Course Charges
KShs. 10,000/= per a participant Accommodation and meals – each participant to make own arrangement. CALL FOR MORE DETAILS: 0724256696 / 0736524200

According to Grace Wanene, you can purchase ready made sterilized substrate from Jomo Kenyatta University of Agriculture and Technology at Juja, 36 km northeast of Nairobi, along Thika-Nairobi Superhighway. Moi University at Chepkoilel sells hybrid mushroom spawns.

Alex Njenga is on Radio Inooro, Coro, Kameme and KBC (Mali Shambani and Sikio ya Mkulima) and is a keen promoter of mushroom farming.

In 2008, I bought the excellent “The Mushroom Manifesto” as a .pdf from, but regrettably their website has closed. If anybody knows where the copyright holder is, I would be interested in republishing it. While on the subject of books, I cannot recommend those by Paul Stamets highly enough. “Growing Gourmet and Medicinal Mushrooms” is not cheap, (around 2000/- if you can find a copy) but it’s an enormous resource to have.

Lastly, try ringing nearby universities. I’m sure I have seen extension programmes in the past – and if you find something do share it with everybody with a comment below 🙂

Mushrooms Lure Young Man away from the City

Bernardine Mutanu reports an interesting story in Business Daily.

Mr Muchiri inside a mushroom room at his Riamukurwe Village farm in Nyeri County.  One kilogramme of button mushroom is sold at between Sh500 and Sh900 , while the oyster  variety  costs between Sh300 and Sh500 per kilogramme. JOSEPH KANYI

It tells how John Collins Muchiri, 28, left Nairobi to pursue farming at his rural Riamukurwe Wambugu farm in Nyeri, rather than stay in the city. John Muchiri left to grow mushrooms and has never looked back since.

“I have a passion for farming. I left my job as a sales person to do full time farming,” he said during an interview at his home. He received Sh25,000 from his brother and used Sh15,000 of it to pay for a mushroom growing course and Sh10,000 to buy substrate, on which to grow the mushrooms.

He raised more money to study how to make substrate. “I raised Sh75,000 from selling goats and went for another training. It was hard at first because there was no one to guide me on getting raw materials, equipment, and market,” he said.

After acquiring the necessary materials, John Muchiri built a darkroom for growing mushrooms. John Muchiri has since increased the number of darkrooms to five, following a rise in demand for his mushrooms. One darkroom costs between Sh20,000 and Sh30,000 to build, depending on the construction materials used and the size of the structure. A darkroom consists of wooden sections, on which the substrate is placed to allow the mushrooms to grow, walls are covered with polythene papers. A thermometer is placed in each room to monitor the temperature closely.

Medicinal value

With 30 regular clients, he makes at least Sh3.6 million per year through selling the substrate alone. “I get contracts from farmers to make substrate. Making one tonne of the substance costs Sh55,000 and I can make as much as five tonnes for one farmer,” he said. He grows three types of mushrooms: button (Agaricus), oyster (Pleurotus), and shiitake . One kilogramme of button is sold at between Sh500 and Sh900, while oyster costs between Sh300 and Sh500 per kilogramme. He incubates shiitake only on order as it is prized for its medicinal value. Mr Muchiri said he makes between Sh15,000 and Sh20, 000 per day during harvest time. “I want to increase the volume of substrate so that I can supply at least 200 kg of mushrooms per day,” he said. He supplies mushrooms to hotels in Nyeri, Nanyuki, Nairobi, and Mombasa as he looks forward to exporting the produce.
John Muchiri also teaches farmers how to grow mushrooms.
John Muchiri said that patience is the key to the success of any business. He attributed his success to support from his pastor and hotels.

Post-doctoral fellow – soil scientist

If you can contribute to ICRAF’s research on soil spectral methods, especially to further develop experimental and data analytical and interpretation methods that lead to new products, that provide actionable knowledge and evidenced-based policy for sustainable soil management, then you are the person we are looking for. For over a decade ICRAF has being working on soil infrared spectral methods for rapid prediction of soil functional properties. These methods are now being widely applied in land health surveillance schemes that employ a standardized protocol for landscape level measurement and mapping of soil conditions. The framework is being applied throughout sub-Saharan Africa under the Africa Soil Information Service ( as well as in an increasing number of land management projects. ICRAF has recently extended these techniques to include laser and x-ray methods under its new Soil-Plant Spectral Diagnostics Laboratory, and is supporting a network of infrared spectroscopy labs across Africa.

Closing date is 30th April 2012 and more information can be obtained from: the World Agroforestry Centre. Applications for the position of Landscape Ecologist also close on 30th April.

KENYA: Rice and Improving the Yields in Kenya

KENYA: Improving yields key to boosting rice farmers’ livelihoods

Photo: David Hecht/IRINAHERO, 3 March 2011 (IRIN) – After spending Ksh35,000 (US$437) on his 0.4 hectare rice plantation – preparing the land, paying for water, transplanting the rice and hiring casual labour – Vincent Opiyo hopes to make Ksh65,000 ($812) when he sells the rice, which takes about three months to mature.

“I expect to harvest 25 bags [50kg each] from this [land] but I know I could get more if I were to improve the yield,” Opiyo, 49, father of eight, told IRIN at the Ahero Rice Irrigation Scheme in Nyanza province.

In addition to the high costs of inputs, the farmers, who are “licensees” on trust land, struggle to access credit as they lack title deeds.

Were it not for what he earns working for the National Irrigation Board (NIB) – which runs the Ahero scheme – Opiyo would not meet the needs of his family from farming.

“Poverty is very high among many farmers under the Ahero scheme because they never make enough to cover needs such as school fees and payment for medicine when children fall sick; look at the structures we live in, most of them are semi-permanent,” Opiyo said.

“Many of us do not even own a cow or some goats. Our father managed to [send] us to school from the proceeds of his [1.6ha] of rice, but for us, his children, it is no longer enough.”

The average yield of Basmati rice at Ahero is 13-25 (75kg) bags per 0.4ha when it should be 20-30 bags

Low yields, better prospects

According to NIB, the average yield of Basmati rice at Ahero is 13-25 (75kg) bags per 0.4ha when it should be 20-30 bags; while the yield for Sindano rice is 15-30 bags, when it should be more than 30 bags.

At the start of operations in 1969, the Ahero Irrigation Scheme had 519 farmers, each with 1.6ha held on trust by the government. The farmers have since sub-divided their farms among their children but they are not allowed to sub-divide below 0.4ha or sell the land.

In 2009, a farmer-oriented funding arrangement, known as the Revolving Fund, was set up to support the farmers’ production and marketing efforts.

Jacob Ongere, a farmer at the Ahero scheme and an extension officer with the Ministry of Agriculture, told IRIN that with the Revolving Fund and the government’s Economic Stimulus Programme (ESP), things were now looking up.

“The profit that farmers are making is still way below average but we hope this will change with more funding and support in sectors such as marketing and capacity-building,” he said.

Through the Revolving Fund Office, Ongere said, the Ahero farmers hope to boost their livelihoods by “exploiting agronomical practices” to improve their yields – transplanting on time and using pesticides and fungicides.

Sutherlandia frutescens and HIV drug safety trials

by: Munyaradzi Makoni [CAPE TOWN]

A traditional medicine that may relieve symptoms in AIDS patients is to undergo safety and efficacy tests in South Africa.

The department of science and technology (DST) has awarded 10 million rand (US$1.4 million) for the study of Sutherlandia frutescens, which is often called the ‘cancer bush’ and is credited with wide-ranging powers to alleviate symptoms.

The phase IIb trial will be conducted at the University of the Western Cape’s South African Herbal Science and Medicine Institute (SAHSMI), which has been conducting scientific and clinical studies on the plant for seven years.

Sutherlandia is popular with traditional healers, who use it to treat a host of ailments from weight loss to aches and pains. But critics say there is a lack of scientific evidence to support their claims and those of companies that already market products containing the plant.

Anecdotal evidence suggests that Sutherlandia promotes appetite, weight gain, sleep, exercise tolerance and an overall sense of well-being in patients suffering from HIV and AIDS, and studies indicate that it improves CD4 blood cell counts and decreases the viral load. Some believe it may even delay the progression from HIV to AIDS.

A small, unpublished phase IIa trial showed that a preparation using the dried leaf of Sutherlandia was well tolerated with no side effects.

The study’s principal investigator, Doug Wilson, told the South African newspaper BusinessDay that the research is likely to be finalised later this year.

Wilson said that, even if the results were positive, much more work would be needed before consumers would find a Sutherlandia treatment for HIV on pharmacy shelves. Researchers would need to identify the active ingredients before they could start drug development, he added.

Tommy Makhode, the DST’s chief director for communications, told SciDev.Net that his department’s interest stems from the fact that South African researchers developed the formulation that would be registered with the Medicines Control Council if the trial is successful.

Quinton Johnson, director of SAHSMI, said that several challenges, from regulatory delays to public-service strikes, have slowed their research, which began in 2003.

“We continue to experience significant opposition to our work from the mainstream research and pharmaceutical communities, who seem to misunderstand the importance of building bridges between various knowledge systems in support of better public health,” he told SciDev.Net. As a result, he said, his work receives limited funding and academic understanding.

“It has impeded the growth and development of the field focused on the science of herbal traditional medicine,” added Johnson, who is also South African director of the International Centre for Indigenous Phytotherapy Studies.

Most people use traditional medicines, said Johnson, so collaboration to understand this indigenous health system is in the interests of public health.
