Coriander/ Dhania farming

The aroma of Dhania is irresistible and no African cuisine is complete without it. Dhania farming is easy as the crop matures within a short period and requires almost zero maintenance. This means that most of the money you will be making will be profit. If enough manure is applied, they rarely require any fertilizers. Chemical application is rarely needed which saves costs. The demand for coriander is growing rapidly just like for other vegetables like tomatoes, kale, spinach, and carrots.

Location Constraints

These plants are extremely fragile and hence they should not be transplanted from pots to the garden. Instead, the seeds should be sown in the soil directly. Farmers can make rows or seedbeds and sow the seeds.


Coriander requires sufficient sunshine throughout the growing period. Once the seeds germinate and start producing leaves, the plants will require 5 – 6 hours of sunshine.

Dhania Farming: Spacing

The plants become bushy with time and hence proper spacing is important. A spacing of 3 inches will be enough to ensure that the plants receive enough light. Proper spacing also makes weeding and harvesting easy.


Dhania plants are small and only grow a few inches long. They should be harvested once the leaves appear fully grown. However, if you want to harvest Dhania seeds, the plants can be left to bloom. Tiny yellow flowers appear within one week and later on seeds pop out.


Coriander is sensitive to temperatures and cannot thrive when the temperatures are too cold or extremely hot. They thrive in temperatures of between 150C – 260C. However, warm temperatures of about 250C are required during germination.

The seeds should be watered regularly until they germinate. After germination, the plants can be watered after a couple of days. Too much water can cause the roots to rot and damage the plants.

Dhania Farming: Nutrient Management

Coriander requires fertile and well-drained soils. To boost the growth process, manure should be added. Although it does not harm the plants, fertilizer application is not recommended.

Pest Management

Since the plants mature within a short time and are harvested immediately upon maturity, there is no space for pest infestation. However, root rot and powdery mildew can develop when there is too much dampness in the soil. There are chances of aphid infestation after flowering and when the seeds set in. Aphids can cause massive destruction when they eat up the seeds. At this time, a pesticide can be sprayed.

Dhania Farming: Harvesting

Coriander plants are ready to be harvested in 25 -32 days. They should be plucked immediately after healthy green leaves are formed. If they are left for another week the leaves turn feathery and develop yellow flowers and seeds sprout out.

Uses and health benefits of Dhania

Apart from its aroma, coriander has many health benefits. For instance, the seeds can be used to treat griping pain in both children and adults. Also, it treats gastric disorders and cures indigestion. Furthermore, it helps maintain good heart health and treats high cholesterol levels.

Things You Should Know When You Venture into Ginger Farming

Ginger Farming

Ginger farming, especially in Kenya has attracted attention not only from Africa but also from Europe and Asia. Previously, ginger was a low-profile crop. The high demand from Europe, mainland Asia, and African countries such as Tunisia, Egypt, and Algeria who have a taste for spices has boosted the cultivation of ginger. What most people don’t know is that this is a crop with more returns potential.

Uses of Ginger

Ginger rhizomes can be used either grounded or chopped into crisps and be used for many purposes. For instance, they can be used to add flavour to tea and as a spice in foods. Medically, it can be used to minimize acid reflux in the body and to help in fighting menstrual torments, colds, and influenza.

Things you Should Know When you Venture into Ginger Farming

Before you venture into ginger farming, there are a couple of things that you should know. These include;

Pick the best cultivar

Once you decide to do commercial ginger farming, you should look for the best cultivar. The Kenyan, Jamaican, and Indian cultivars are the sorts of cultivars that thrive in Kenya. The Jamaican cultivar, however, is the most suggested for commercial farming. Indian and Kenyan cultivars are viewed as sub-par and have a dim skin hence not ideal for commercial purposes. 

Ideal soil conditions and climate for ginger farming

The size and shape of tubers are some of the factors that people consider before buying. Ginger performs best in soils with an alkaline or neutral pH. Acidic soils influence the size and shape of ginger rhizomes and hence farmers should not cultivate ginger in such soils. Ginger thrives in areas that receive overwhelming precipitation that is followed by a hot dry season. In Kenya, they flourish in Coastal areas and areas close to Lake Victoria.

Nematodes in Ginger Farming

Ginger rhizomes are susceptible to nematodes although they can be managed by ensuring crop rotation with plants such as chillies. Farms that have been previously used for cultivating bananas should be avoided since they increase the possibility of ginger being affected by nematodes. Ginger rhizomes should be dipped in fungicides before planting to minimize the cases of nematodes.

Manure and Fertilizer Application

To ensure healthy growth and optimum yields, regular manuring should be ensured. Manure should be applied regularly to ensure that the plants have the necessary nutrients. Fertilizers can also be applied especially in soils that are not fertile to provide the plants with the required nutrients. Fertilizer application is recommended during planting.

Weeding and Mulching

Mulching plays an important role in ginger farming. For instance, it enhances water retention, increases soil fertility and helps in controlling weeds. Also it minimizes water loss through evaporation. Ginger can be mulched using grass or debris. Weeds can compete with the plants and hence they should be controlled early. Chemical control should, however, be avoided.

Harvesting and Storage

Time for harvesting the rhizomes varies and their demand is high throughout the year. Ginger takes between 8 – 10 months to mature depending on the weather conditions. After harvesting, dried ginger should be stored in an area that free from dampness. One acre can produce about 10 tonnes of crisp ginger. In the local market, a small ginger rhizome goes for around KES 5 – KES 10 depending with the market and hence you can imagine the amount of money you will receive with 10 tonnes.

How to Grow Hass Avocados Organically

Recently, there has been a rising demand for organic crops, especially fruits. The demand for organic hass avocados has been on the upswing in the local and international markets. Farmers have shifted from farming less profitable crops like maize and beans to fruit farming. Although there are more than 40 avocado varieties, hass avocados organically grown is most preferred in the international market since it has a richer taste and higher fat content. The fruit is on high demand in international markets such as the UK, Spain, the Middle East, Russia, and China. In China, it has a market share of more than 70 percent.

How to grow hass avocados organically

Compared to conventional chemical-driven farming, organic hass avocado is cost-effective and hass many benefits. However, to achieve maximum productivity, one needs to understand the soil’s ecosystem in the region. To effectively maintain the soil productivity, the soil should be well aerated and the pH maintained at a constant. Medium sandy loams with a pH ranging from 5.5 to 6.5 are suitable for Hass avocado farming. Avocados thrive in well-drained soils and are sensitive to water-logging. Poorly drained soils support the growth of Phytophthora fungi which causes stem and end rot.

Farming Hass avocados organically starts with proper seedlings. Farmers should purchase certified and grafted seedlings for optimum results.


The trees should be well spaced to allow free circulation of air. The spacing should range from 6m by 7m to 8m by 10m with a hectare occupying from 125 to 180 trees.

Planting and Fertilization

Planting holes of about 50cm*5cm*50cm should be dug. The topsoil should then be mixed with enough manure and DSP to improve soil fertility. After planting, the young avocado trees should be watered and mulching. Using inorganic fertilizers kills microorganisms due to acidity and degrades the water retention rate in the soil. Farmers should hence consider using compost and manure instead of inorganic fertilizers. To minimize water loss through evaporation, farmers should mulch their young trees with dry leaves or well-dried grass.

Pest control

Biological pest control practices reduce the consumption of chemicals by humans. Growing Hass avocados organically they are prone to mosquitos and whiteflies. Introducing praying mantis can help minimize the mosquito population on the farm. Since they feed in the morning, late afternoon, and at night, they can damage a large number of fruits. Proper sanitation on the farm should be observed. All fallen fruits should be removed since they provide a breeding ground for whiteflies. Alternative hosts such as guavas should not be planted close to hass avocado plants.

Rearing Bees

Bee farming has been a profitable venture for more than a decade. Rearing bees near avocado farms is important since the improve pollination hence increasing the overall yield. 

Why it is important to buy hass avocado seedlings from a certified nursery

It is quite disappointing to buy poor quality seedlings only for them to underperform and produce insignificant yields. Buying seedlings from a certified nursery has many benefits such as;

Risk management

Varietal quality and purity are strictly monitored to facilitate only the production of the best varieties. Certified seedlings enable farmers to have confidence in what they are planting.

Access to new opportunities

Purchasing certified seedlings offer recognizable proof of the variety of your avocado plants and hence farmers can access premium markets with confidence.

New genetics

Certified seedlings are resistant to most pests and tolerate harsh climatic conditions.


Basic methods of improving your Hass avocado productivity

Control Pests and Disease

Prevention is the most economical and efficient way of controlling pests and diseases. These methods include supplying enough nutrients to plants, weed control, maintaining optimum plant density and proper selection of seedlings. In Kenya, pest control rarely requires chemical control. Some major pests that attack Hass avocados include thrips, scale insects, and false codling moth. Avocados are also susceptible to fungal diseases such as root rot, anthracnose, Cercospora fruit spot, and scab. Root rot is common in areas with poorly drained soils, or areas prone to flooding. Farmers should ensure that the soils are aerated and well-drained. It can be prevented by planting grafted seedlings that are resistant to phytophthora fungi. In severe cases, it can be controlled with fungicides such as Ridomill. Anthracnose mainly attacks the mature fruit forming brown spots. Scab attacks the fruit, leaves, and twigs. Cerspora mainly attacks the fruits and leaves leaving yellow spots. These diseases can be controlled using copper-based fungicides with high mancozeb content. Controlling pests and diseases can help in maintaining the quality and quantity of fruits enhancing the productivity of fruit trees.

Introduce bees

Rearing bees helps in enhancing pollination in while growing hass avocados organically which increases the overall yield.

Mulching increases the organic matter in the soil and helps in conserving moisture. Also, it enhances water retention which promotes avocado growth. Mulching should be done using well-dried grass, although dry leaves can also be used. As sawdust decomposes, it ties up nitrogen and hence should not be used.


Avocado trees require adequate water throughout the year and hence regular irrigation is important. Sprinklers and jets can be used for irrigation since they wash and knock off pests and eggs on the avocado plants. Water used must be salt-free since avocados are intolerant to salinity.

Pruning triggers vegetative growth and helps in removing shoots coming out of the rootstock.


Avocado farms should be free from weeds since they act as alternative hosts of pests such as whiteflies.

Manure application
Manure should be added regularly to plants to supply them with the necessary nutrients for optimum yields. Inorganic fertilizers should be used sparingly since they kill microorganisms responsible for decomposition and aeration in the soil.


The overall yield of Hass avocado trees depends on several factors such as plant density, soil fertility, and proper pest and disease control. Climatic conditions in most parts of the country favor the production of Hass avocados. Pesticides Minimum Residual Levels (MRL) guidelines set by the European and Asian markets remain a challenge to farmers. Without crucial information on pesticide use, fruit farmers are in danger of having their entire produce being rejected by export companies. Organic farming, however, entails minimum use of chemicals and hence the MRL guidelines are not a threat. However, they should ensure that their fruits are of high quality and free from pests and diseases.

After Coffee, Hass avocado is the second profitable crop

Kenyan hass avocado has gained popularity in the international market especially in China and Asian countries where the population is high. Hass avocado is the second most profitable crop after coffee. However, if the available fertile land is utilized and put into hass avocado farming, the crop can overtake coffee. Compared to coffee, the yields per tree are higher in hass avocado. Farmers seeking diversity in agribusiness should consider growing hass avocado. Due to climate change, there has been a significant reduction in avocado production in South Africa and countries in the southern hemisphere like Mexico. These countries were the dominators of the Asian market and hence with the decline in production, there is a ready market for Kenyan avocados.

Why I Shifted From Coffee to Hass Avocado Farming

Hass Avocado Farming

From far, the farm resembles a splendid rain forest with evenly spaced trees growing in straight lines. As one approaches Maina’s farm, one cannot fail to notice dozens of hass avocado fruits hanging loosely from lush-green trees.

What made you venture into Hass avocado farming?

“There are dozens of ripe fruits in the farm and I will be harvesting in the next few days,” Maina Karuiru says happily. Karuiru started practicing avocado farming in 2006 on his farm located in Mathira, Nyeri County. He started avocado farming when the coffee industry became shaky and barely bringing any profits.

“I am happy that I shifted from coffee to Hass avocado farming. Most of my colleagues who stuck to coffee have faced numerous challenges as the once-lucrative industry declines.”

The farmer recalls couple of years ago when coffee farming was a lucrative venture. “In the 1980s, coffee prices were relatively high, and we used to make good money. Unfortunately, there has been a significant drop of coffee prices in the international market. Considering the maintenance costs for the crop, coffee farmers are barely making significant profits.”

Karuiru uprooted 500 coffee trees to make room for the avocado trees. This was his first step to shift from coffee to avocado farming, a move that was not supported by his neighbors. At first, Karuiru started with 100 trees and increased the number to 222 in the second year. Currently, he has 322 avocado trees that are evenly spread on a three-acre farm. 

Compared to coffee, avocado farming is a profitable venture and the trees require little maintenance.

“Previously, when I was doing coffee farming, 500 coffee bushes earned me Sh 41,000. Last season, I earned Sh 37,000 from 7 avocado trees, which is the reason why I uprooted the coffee bushes.”

Karuiru has two varieties in his three-acre farm; Fuerte mainly for the local market and hass avocado mainly for export. He targets the European market and exports most of his produce to European countries.

When should you plant Hass Avocado?

“Seedlings should be planted at the beginning of the rainy season. Trees require a lot of water especially when after planting. They should well-spaced, with a spacing of about 7 by 7metres. Poor spacing makes the canopies to overlap and causes a significant drop in the yields.”

Do you use manure during planting?

For better growth, the holes should be filled with 5kgs of manure during planting. DAP fertilizer can be added later to boost the growth of the trees. Karuiru prefers goat droppings for manure. Compared to cow dung, goat droppings decompose faster.

Which variety do you have in plenty?

On his farm, Karuiru has the hass avocado variety in plenty. “The demand of Hass avocados is high both in the local and international market, and fetches good prices,” the farmer says. In the export market, one Hass avocado fruit goes for an average of sh10 and even higher. Europe, especially Holland, Germany, France and U.K, Middle East, Saudi Arabia, and China offer the market for avocados. Karuiru mainly exports his fruits to Holland and France but he is eyeing the Chinese market also.

Avocados fetch him more than Sh 600,000 every season. “With the high profits from avocado farming, I cannot go back to coffee,” he says.  To produce more fruits in the next season, Karuiru prunes his trees after harvesting. He also keeps bees to boost pollination.


Where to buy seedlings

Karuiru advises farmers to be careful when buying seedlings, especially when buying from roadside nurseries. Poor quality seedlings mean poor production of the trees and low yields. Farmers should buy seedlings from certified nurseries. Oxfarm LTD offers high-quality seedlings. Unlike other sellers, Oxfarm offers agronomical support to farmers to ensure that they employ proper farming techniques and also help them get market for their produce.

How to make macadamia Farming profitable venture

Macadamia farming is a lucrative venture that many farmers are beginning to get into. The increasing demand and good prices of macadamia nuts make it an ideal venture for low-income earners.

Macadamia farming has attracted a large number of farmers and it’s proving to be a profitable business venture for them. The increasing demand and high profits realized in macadamia nut farming make it an ideal business for low-income farmers.

How to make macadamia Farming a profitable venture

Different ways can be employed ton make macadamia a profitable venture. These include;

Planting high-quality seedlings

Grafted, high-quality seedlings produce more yields per tree when proper farming techniques are employed. This incorporates utilizing the available resources, land, and manpower. For instance, a grafted macadamia tree can produce an average of 180kg in one season fetching you Ksh 27,000 when one kg is going for 150 shillings. You can imagine the amount of money you will get when you have 100 trees.

Train farmers

Lack of skills and sufficient information on how to grow macadamia is the biggest challenge facing macadamia farming. Lack of information makes farmers produce low-quality nuts and in the process suffering financial losses.

Eliminate middlemen by forming groups and cooperatives

Other sectors such as tea and coffee were filled with middlemen who buy the produce from farmers at low prices. Formation of member-run cooperatives and groups that are responsible for marketing the macadamia produce and hence farmers will be able to fetch good prices for their nuts.

What are the challenges that macadamia farming face

Seasonality of the harvest

Insufficient quantities of unprocessed nuts and seasonality of harvest are one of the challenges that macadamia farmers face. Seasonality makes farmers unable to meet the increasing demand for nuts resulting in high competition from other countries. Macadamia farmers need to expand their production units which are possible through the provision of affordable, grafted seedlings.

Unscrupulous traders

The exportation of unprocessed nuts in Kenya was banned in 2009. Unfortunately, there are still unscrupulous traders who export unprocessed nuts to international markets such as China. This poses competition to processors who export processed nuts and this creates a competitive space in the international market. Previously, China was one of the main markets of Kenyan and South African macadamia nuts. Unfortunately, they have started planting macadamia trees and hence relying on the Chinese market is unsustainable.

Lack of quality seedlings

The majority of farmers grow native macadamia varieties that use a lot of resources, manpower and time but produce low yields. Low-quality seedlings perform poorly regardless of the topology, rainfall, and soil composition. Farmers should shift to grafted varieties and purchase high-quality seedlings from certified sellers since they have a short maturity period and provide high-quality nuts.

Taking to market unripe produce

This is common when the demand for macadamia is high and local production cannot meet the demand. Shipping unripe and unprocessed nuts makes farmers lose money especially when shipping to Asian markets like China. Harvesting immature nuts mainly happen when farmers beat the nuts off the tree. These days, buyers have an effective grading mechanism and they can easily separate immature nuts from the mature ones. On most occasions, they reject the unripe nuts and the loss borne to the farmer. If they buy the immature nuts, they average the prices and hence farmers are unable to enjoy the competitive prices.


When the demand for macadamia is high, farms are sometimes raided by thieves. In some regions, macadamia farms go to the extent of seeking for armed security from police officers.

Selling through brokers, instead of through direct contracts

Brokers have dominated the nut industry. Most processors buy nuts through brokers and hence farmers are unable to enjoy the competitive prices of macadamia nuts.

More and more farmers enter into macadamia farming

Over the past few years, more farmers have ventured into macadamia farming because of several factors such as;

Low returns in other sectors

Previously, coffee and tea were the leading export crops. Unfortunately, the changing global economy and middlemen have made the once-lucrative venture to shrink, with farmers incurring losses. In some regions, farmers have already started clearing their coffee bushes to create space for macadamia trees.


Nuts can be used in various forms such as in the production of oil for cosmetic and pharmaceutical use, consumed raw, or added to food items.

Reuse and waste reduction

Macadamia husks can act as fuel reducing the usage of charcoal and firewood.

Short maturity

Macadamia matures within a short period but acts as a lifetime investment since they last for a couple of decades.Grafted macadamia seedlings mature within 2 years and have a high productivity rate. Non-grafted seedlings take 5 years to mature.

Value addition of Macadamia

In Kenya, instead of adding value locally and exporting finished products, we sell raw macadamia losing a big opportunity. For instance, importers buy raw nuts in Kenya and use them to add value to chocolate. They then export macadamia-chocolate at a higher price making them earn more money than the raw nuts they bought from Kenya. Farmers can form processing plants, add value to other products such as chocolate and then export them as finished products. For instance, they can use nuts to manufacture oil for pharmaceutical and cosmetic products, detergents, and adding value to foodstuffs such as chocolate and cakes. This way, they can enjoy 100 percent profit from their nuts.

Market Analysis of Macadamia nuts

Previously, the macadamia industry was dominated by middlemen who fetched a high percentage of hard-earned macadamia farmers’ profits. Currently, there are more than 27 certified and licensed processors who buy the nuts from farmers directly and hence eliminating middlemen. These processors also offer advice and financial services to farmers hence shielding them against losses and exploitation. Farmers should, however, be careful since some people come and purchase their nuts at low prices either due to the desperation or ignorance of the farmer and export them at high prices.

The market for Kenyan nuts is quite broad, spanning from local to international. The diversified use of macadamia nuts facilitates a wide range of market opportunities. Kenya has managed to tap the Chinese market where the demand for macadamia has been increasing. The demand has also been increasing in Europe, Asian countries and America. Due to the high demand, prices of macadamia nuts have risen even up to KES 180 per kilo. Coffee berries, on the other hand, have been retailing at KES 55 per kilo, prices which as incomparable to those of macadamia.

Value addition of Macadamia Nuts and Why we should embrace it

Macadamia nuts

The consumption of macadamia nuts in Asia, America, and Europe is positive and the demand has been increasing constantly. This has been fuelled by the increasing interest in healthy eating. Macadamia nuts are a source of vitamins, fibre, minerals, protein, and unsaturated fats. They are considered to be rich in iron, vitamin A, niacin, folates, thiamine and riboflavin. Raw macadamia nuts are not produced in Europe and hence most countries are forced to import.

Why we should sell value-added products

Value added products cost higher than raw macadamia nuts. For instance, importers buy raw nuts importers buy raw nuts and use them to add value chocolate and then export the macadamia-chocolate at a higher price. This way, they earn more money than the raw nuts they imported from Kenya. Farmers should aim at forming groups and coming up with processors whereby they can process their nuts to add value to other products and export value added products. This way they can manage to fetch more money than when they sell raw nuts. Currently, there are more than 27 certified and licensed processors who buy the nuts from farmers directly.


The consumption of nuts in Europe, Asia and America is increasing at a rate of 19percent. Previously, the demand for macadamia was lower due to low harvest of macadamia nuts in various parts of the country which resulted to a decrease in consumption.

In Europe, Germany is largest consumer of macadamia, which consumed 1870 tonnes and a consumption of 116 grams of nuts per capita in 2016. Luxembourg was the largest consumer of macadamia nuts per capita due to its processing facilities consuming 1.4 kg per capita. Other major consumers of macadamia nuts in Europe are Spain, Italy, and United Kingdom. In Asia, China and Japan are the largest consumers of macadamia nuts products.

In Europe, the consumption of macadamia nuts is seasonal reaching a peak in winter months, and the consumption reduces towards the summer.

Value addition of macadamia nuts

The consumer demand of gluten-free, natural, and vegan food, especially in Europe and Asia creates opportunities for exporters in Kenya. Farmers have a guaranteed market for their produce hence they can venture into macadamia farming with confidence. However, exported produce should meet all the requirements for the international market, be free from pests, and adhere to corporate standards.

In Kenya, instead of adding value locally and exporting finished products, we sell raw macadamia losing a big opportunity. The global macadamia nuts market has expanded especially after the application of the nuts in personal care, food & beverage, and others. The food & beverage sector accounts for the largest share in the global nuts market due to the extensive use of nuts in culinary segments, dairy and frozen desserts, bakery, and confectionery. These days, macadamia are used to add value to breakfast biscuits, chocolate products, breakfast cereals, macadamia nut butter, cakes, and breakfast biscuits. There is also widespread use of macadamia oil in personal care and cosmetic products such as shampoos, lotions, and moisturizers due to high palmitoleic acid and natural antioxidant properties. 

Macadamia nuts enjoy a good reputation in among Asian and European consumers. The consumption of nuts is expected to increase in the cosmetic and snack segment. In European countries, macadamia are regarded as a healthy alternative of junk food such as extruded snacks and crisps and healthier than peanuts.

Local and Global Market Analysis of Macadamia nuts

Macadamia nuts

Global macadamia market shows a steady upward trend

The global macadamia market has continued to show a steady upward trend and it’s expected to be a billion-dollar industry by 2024. The demand for macadamia nuts has been rising globally, although the supply is still low in the international market. This has resulted in variations in the demand and supply of nuts. To speed up the development of the macadamia market, there is a need for investments in the industry including contributions from the government and NGOs. 

Factors that result in the high demand for macadamia nuts

Various factors have fueled the demand for nuts which include:

  1. The nutritional value and health benefits of macadamia nuts especially their high content of minerals and vitamins.
  2. The growing use of macadamia in cosmetics and personal care products such as shampoos.
  3. The growing use of macadamia nuts to add value to confectionery products and beverages.
  4. The increasing awareness among consumers about natural cosmetic ingredients.

Due to their high demand, the prices of macadamia have been relatively high in the international market and the majority of nut farmers have smiled at the bank. In the macadamia value chain, about 30 percent buy macadamia seedlings from companies. However, only a small percentage sells their nuts to companies directly demonstrating a weak relationship between macadamia companies and the farmers. The relationship is quite strong between brokers and farmers. However, some companies buy nuts directly from farmers.

Importance of selling directly to companies

Selling to companies is important since farmers get basic training on macadamia farming.

Farmers can enjoy relative price stability and organic certification.

They also learn about product innovation, international collaboration, and gain technological know-how.

Market analysis of macadamia nuts

The market for Kenyan nuts is quite broad, spanning from local to international. The diversified use of macadamia nuts facilitates a wide range of market opportunities. Kenya has managed to tap the Chinese market where the demand for macadamia has been increasing. The demand has also been increasing in Europe, Asian countries and America. Recently, the high demand has even made the prices of macadamia nuts to rise to KES 180 per kilo.

In Europe and Asia, the processing of macadamia nuts has been increasing rapidly. Raw macadamia cannot be produced in Europe and most parts of Asia due to the climatic conditions and hence the nuts have to be imported. Europe and Asia offer the largest market for macadamia. In Europe, macadamia are mainly processed by blanching, roasting, salting, and spicing. Luxembourg is one of the top nut processing countries in Europe. Market opportunities can be found in the growing markets of Eastern and Central Europe. Currently, Germany, the United Kingdom, and the Netherlands are the largest import markets for Kenyan macadamia offering good opportunities for exporters in Kenya. In Asia, China offers the best market for Kenyan nuts.

Due to the high consumption of macadamia products, steady growth is expected. Since 2015, macadamia imports have increased in Europe at a rate of 10% in volume and 19% in value which shows that import prices have increased. Heavy investment in macadamia farming in Kenya can help farmers to gain a higher market share for their nuts in the European market over leading suppliers from the USA, Australia and other parts of the world. In Kenya, macadamia farming has no restrictions and regulations in the international market and therefore the prices are determined by the demand and supply of nuts in the market. Farmers should hence consider venturing into the lucrative business.

Differences between yellow and purple passion Fruits

Passion fruit is tangy, sweet and delicious that has a low-glycemic index. Apart from being sweet, it is an antioxidant-rich fruit. They grow vigorously into climbing vines and can serve as green walls for your property. They are evergreen throughout their growing period, covering trellises and arches and hence can act as excellent privacy screens. However, they require maintenance and can be invasive. In Kenya, the yellow and purple passions thrive in different parts of the country. However, there are several differences between the yellow and passion which include;

Difference between yellow and purple passion fruits

Characteristics of Yellow passion

  • Has a large fruit with a yellow rind
  • Has a more acid flavor
  • It’s resistant to Fusarium wilt and nematodes
  • It has brown seeds
  • It has a more vigorous vine and more tolerant to frost
  • The flowers are self-sterile with heavy and sticky pollen and hence wind pollination is ineffective. Since their pollen is sticky and the flowers have to be pollinated, bees are the most effective pollinators.

Characteristics of purple passion

  • Has a smaller fruit with a purple rind
  • Has a less acidic flavor, a sweet pulp, and a higher juice proportion
  • It has black seeds
  • Has a less vigorous vine
  • It can self-pollinate and has light pollen. Pollination is, however, best under humid conditions.

When crossing purple and yellow passion, it is important to use the purple parent as the seed parent since the flowers of yellow passion are not receptive to pollen from the purple passion variety. Crossing the yellow and purple passion enables the plant to withstand the woodiness virus.

Best places to grow passion fruits

In Kenya, passion fruits are grown in Nyeri, Kiambu especially in Thika, Kakamega, Murang’a and Kisii. However, before engaging in passion farming, you should have your soil thoroughly assessed. The soil should be examined to identify the soil texture, type, depth, nutrient and nematode levels, and chemical analysis. They perform best in light to heavy sandy loams with good drainage and of medium texture.

Climatic and soil conditions

Yellow passion is mainly for the fresh fruit market and grows well at altitudes of 0 – 800 m. This means that it can thrive in the coastal region. On the other hand, the purple passion performs well at high altitudes of 1200–2000 m and barely flowers at altitudes of below 1000. It can perform well in high altitude areas such as Thika, Murang’a, Nyeri, and Meru. The yellow passion can be used as a rootstock for grafting of the purple variety.

Passion grows well at a pH of 5.5-7. It does not thrive in acidic soils, although lime can be applied to neutralize the acidity. To minimize the chances of diseases such as collar rot, passion fruits should be grown in well-drained and aerated soils. Passion fruits require adequate rainfall although it can be put under irrigation especially in dry areas. However, it does not require extreme temperatures and hence the vines should be sheltered especially in dry areas. The optimum temperatures for yellow passion range between 250C-300C and between 180C-250C. In extremely low temperatures, pollen does not germinate and the plants produce few flowers.

Places that Grape farming thrives

If you are a wine lover, you might have heard salespeople or winemakers proclaiming some bottles to be unique thanks to high elevation vineyards. Why do they emphasize on high elevation when it comes to finished wine? Vineyards are set on high elevations because of greater temperature fluctuations, solar rays, and scarcity of water resources. High elevation grape farming is exposed to environmental limitations and challenges that help shape highly-acclaimed and unique wines. In Kenya, in Meru, Mombasa, Kibwezi, Mandera, and Naivasha, and parts of Nyeri like Othaya. are the best grape farming areas.

How Solar Rays and Temperature Affect Wine at Elevation

The acidity and tannin structure of a wine is developed in the vineyard and it’s mainly determined by the temperature shift that the vineyard sees from day to night and the exposure to the sun. The intensity and density of solar rays increase as you move upward in elevation. This means that the temperature and direct sunlight hitting the vineyard increases.

Hillside vineyards tend to receive more concentrated and direct sunlight which makes the grapefruits develop thicker skin enhancing the color concentrations and resulting in stronger tannins and flavor profiles.  Greater temperature shifts between day and night are experienced in high elevation areas. When the sun sets, temperatures drop although this shift depends on the altitude. The cooler nights throughout the vineyard enable the grapes to conserve their acidity resulting in age-worthy wines. Temperature shifts also help to lengthen the growing season giving grapes more time to develop and mature on the vines. With a sloping terrain, Naivasha is one of the places where grapes can perform well. It has a warm and dry climate where grapes can receive the sun throughout the day.

Climatic conditions for growing grapes

Kenya’s climate that ranges from tropical climate to highland, arid and semi-arid climate makes it ideal for grape farming. Sufficient water, adequate sun, and heat favor viticulture. These factors are important to promote healthy growth of the vines. During fruiting, grapes require warm or hot temperatures and hence the weather must be dry and sunny. Warm temperatures increase the sugar content of the grapes.

This explains why grapes grown under irrigation in arid and semi-arid areas such as Mandera are sweeter than those from humid regions. Apart from the cool climate, Kenya has cool nights, warm days, fertile soils, and moderate rainfall which provide the optimum conditions for grape farming.

The crop thrives in well-drained soils especially in sandy and loamy soils.

Vines can be damaged by frost which happens when temperatures go below 00C. During vegetative growth, the physiological processes of grapevines begin when the temperatures are above 100C. In Kenya, the average temperatures range between 170C – 200C which are ideal for vegetative growth and flowering.

When temperatures rise above 200C, most of the physiological processes are complete and the grape clusters begin to ripen. Naivasha has temperate climates that give the vines long, warm periods which are important during flowering, fruit set, and fruit ripening.

Other factors that influence viticulture are humidity, sunlight, and wind. Grapes do not require high humidity or strong winds and perform best in places where they are put under irrigation. They thrive in places with light winds such as Naivasha and Meru.

When there is little moisture, irrigation should be ensured. However, irrigation should be withheld after heavy rains to minimize excessive vegetative growth and to force the crop to go dormant. The cropping season is from September to March. Between August and September, fruit buds should be forming and hence the plants should be kept healthy and well manured.

When should you plant plantain Bananas?

Currently, plantain farming is one of the most lucrative ventures in agriculture. Unfortunately, most farmers lack the necessary knowledge needed to start a plantain plantation and hence miss out on the profitability of agri-business. Plantains have fruits similar to bananas, but unlike bananas, the fruits remain green and don’t turn yellow when they ripen. Plantain fruits are mainly boiled, steamed, or fried although they are also eaten raw. With high demand, they can be a good source of revenue even to local farmers.

Climatic factors

Plantain is sensitive to temperatures and hence cannot thrive in areas that are extremely cold or too hot. The tropical climate is ideal for plantain, especially in areas where temperatures are between 200C to 300C. The optimum temperature for plantain farming is 270C . These bananas cannot survive in temperatures below 140C. At low temperatures, the leaves and the fruit turns yellow and eventually the plant dies. The bright sun, warm temperatures, and adequate rainfall create an optimum environment for plantain farming.

They require adequate rainfall although they can be put under irrigation. If they have enough water, they can handle extreme temperatures and cool weather. However, in extreme temperatures, they do not thrive.

A pH of between 5.5 and 7.0 is the best for plantain farming.

In Kenya, plantain farming can thrive in most parts of the country especially places such as Tharaka Nithi, Meru, Nyeri, Kisii, Muranga, Embu, Nyamira, and Kirinyaga.

Time to Plant Plantain Bananas

Plantain suckers can be planted after land preparation. The land should be prepared before the rainy season and the suckers planted during the rainy season. During the first 3 to 4 months after planting, the plants should be well watered to ensure vigorous vegetative growth. This means that they should not be planted in the last month of the rainy season. This means that they can either be planted between March and April or between October and November.

However, fetch good returns, farmers can also plant during the dry season and put the plants under irrigation. Most farmers plant immediately when the rains start and flood the market when the plantains mature which causes the prices to be very low. Planting during the dry season or in the middle of the rainy season puts farmers in a better proposition since they will harvest they plantain off-season and hence get high prices.

Weeding and fertilizer application

Weeds can compete for nutrients with plantain plants slowing down their growth. Constant weeding is hence important. Chemical weed control is, however, not recommended.

The application of fertilizers will be based on soil fertility. To know the soil fertility, a soil test is recommended before planting. If the application of fertilizers is necessary, it should be applied in the right proportions. Manure should be added regularly to improve soil fertility. Mulching should also be applied since it not also minimizes water loss through evaporation but also improves the soil fertility when the mulch decomposes.

Maturity and Harvesting

Plantain fruits take between 8 to 10 months to mature and be ready for harvest. Harvesting is done when the plants begin to ripen. A bunch ripens within one week. The plant produces more fruits throughout the entire season. The fruits should be harvested carefully so as not to hurt the fruits.


The profitability depends on how they are maintained. The demand for plantain has been increasing over the years and there is always a ready market for the fruits. In Kenya, the consumption of plantain fruits is high. Farmers can either sell the fruits in the local market, to companies that process plantain into flour or export to the international market. In East Africa, South Africa, and Asia, the market for plantain is large and is increasing over the years.
