Kenya is sitting on a gold mine that if properly utilized would reap huge benefits for its people. For many years, tea and coffee farming in central Kenya and other parts of the nation has been the major source of income for thousands of
farmers, however the macadamia wave is overwhelming and they are now changing tides and switching to macadamia nut farming.
Macadamia nuts has become a lucrative produce all over sudden with a kilo of the nuts selling for more than a hundred and a grafted seedling price shooting up from 300 to 500 Kenya Shillings.
Between1986 to 2002 the price ranged between 7 to 23 Shillings per kg., and in 2005 it averaged 80 Shillings per Kg. For a long time, Kenya has been ranked second in production of Macadamia worldwide after Australia.
According to Dr. Lusike A. Wasilwa, Assistant Director Horticultural & Industrial Crops, Kenya Agricultural Research and Livestock Organization (KARLO), Macadamia would do better if its production is fully optimized. “Kenya Macadamia nut is the king of the nuts; it is going to be known in the World as the most expensive chef meal. It makes the food taste very nice; as it has 72% of natural oil. It enhances other tastes in salads, cakes, cookies, chocolates, biscuits to mention but a few; making them pronounce. Its oil is natural, no perfume, not greasy, not shiny but a natural sunscreen that have anti-aging nutrients, anti-dandruffs, anti-ringworms thus very best for lotions.” Dr. Lusike affirmed adding that the most expensive lipstick is made from macadamia.
ORIGIN OF MACADAMIA
Macadamia is an old industry introduced into the country in 1942 from Australia. In 1960 the Government had an elaborate program of promoting macadamia from seeds that were planted and nurseries set up. These seed nuts were brought as shade crop for coffee to perform better in reduced temperature. In 1966 a lot of nuts had been planted in Central- Kirinyaga, Kiambu and Muranga, Eastern- Meru and Embu, Kakamega- Bukula and Bungoma – ADC.
The Japanese in 1972 realized that this is a plant they could help develop thus they brought an expert through JICA to help in selection of varieties that were good from the many different varieties that existed from the originally planted seed nuts. These scientists were based at Thika Horticulture Research Institute then known as National Horticulture Research Centre. They selected 30 varieties with high potential from different zones of the country; from the coffee main zones, from dry zones and from the highlands. An analysis was done in 1986 and Macadamia Development project was set at Practical Training Centre.
From the 30 varieties, 3 grades were selected, whereby the higher the oil contents in the macadamia the higher the grade but also the size in relation to market mattered. “It was the earliest research commodity in response to the market; for most of other commodities, they are bred for high agronomic yields but for macadamia it was the varieties that would fit a zone for example Murang’a 2. It has good yields; big nuts, thus I used to call it African nut”, Lusike explains.
Other varieties selected include Kiambu 3 & 4, Meru 23 & 24, Taita Taveta 1 & 2, Kirinyaga 15 and Murang’a 20, which until today is one of the best with very wide adaptability.
Macadamia is a beautiful tree, very forgiving; resilient to all weather, accommodative for old people; they don’t need to work so hard nor climb to pick the nuts but wait for them to fall. The other thing that makes Macadamia feasible product is the fact that the farmers can market their produce. “Macadamia is the only produce that the price is determined at the pick-up that is collecting it as per the wish of the farmer. ” Dr. Lusike indicates. Currently, macadamia nut farmers sell their products to brokers who link them with processing companies such as Kenya farm nut companies amid others. A macadamia nut processing company was built in Karurina area of Embu County sometime back but it has never started working. Macadamia nuts can be eaten raw or processed to produce cooking fat.
Macadamia tree is permanent unless affected by a disease like powdery mildew at flowering stage. Production starts at three and a half years for grafted varieties and seven years for local varieties. The main varieties planted in Embu region are Murang’a 20 which has been branded the name Mugumo in the area because of its good performance. It has a tendency of producing a few nuts year through after the main season and is the best yielding variety. The tree can produce an optimum of 70kgs under good management. the macadamia nut trees should be planted at a spacing of 7.5m by 7.5m.
According to Dr. Lusike, its seeds are a valuable food crop that is sweet when eaten raw. “It is good for the kids who love them.” She adds. Only three of the species, Macadamia integrifolia, Macadamia ternifolia, and Macadamia tetraphylla, are of commercial importance. Only two of these three species (Macadamia integrifolia and Macadamia tetraphylla can be eaten raw.
The remainder of the genus possesses poisonous and/or inedible seeds, such as M. whelanii and M. ternifolia; the toxicity is due to the presence of cyanogenic glycosides. These glycosides can be removed by prolonged leaching, a practice used by some Indigenous Australian peoples for these species, as well. Compared with other common edible seeds such as almonds and cashews, macadamias are high in fat and low in protein. They have the highest amount of monounsaturated fats of any known seed and contain approximately 22% of omega-7 palmitoleic acid which has biological effects like monounsaturated fat. They also contain 9% protein, 9% carbohydrate, and 2% dietary fiber, as well as calcium, phosphorus, potassium, sodium, selenium, iron, thiamine, riboflavin and niacin.
Macadamia has great potential for poverty reduction due to the high value of its products and its low requirement for external inputs and a lot need to be done to improve the industry. Although the crop has been grown in the country for over 5 decades, the growth of the industry is not commensurate with the demand and market potential that exists.
Some of the challenges facing the macadamia industry in Kenya include lack of cultivars adapted to various agro-ecological zones, inadequate planting materials of high quality, high cost of the available good quality planting materials and pests and diseases that affect nuts thus lowering post-harvest quality. The potential of agricultural biotechnology is relevant to genetic improvement of macadamia to compliment other efforts for its productivity and value. The beauty of macadamia is that it gives food nutrition security to children. The farmers say the product fetches better prices than coffee and tea regardless of how often they are harvested.

Tangerines are relatively cold-tolerant, making them easier to grow than oranges, grapefruits and other types of citrus. Some varieties, such as the Citrus reticulata "Dancy," are heat-tolerant and do best when summers are hot, but other types, including the Citrus reticulata "Sunburst," do best when summers are on the cool side.
Citrus species can thrive in a wide range of soil and climatic conditions. Citrus is grown from sea level up to an altitude of 2100 m but for optimal growth a temperature range from 2° to 30° C is ideal. Long periods below 0°C are injurious to the trees and at -13° C growth diminishes. However, individual species and varieties decrease in susceptibility to low temperatures in the following sequence: grapefruit, sweet orange, mandarin, lemon/lime and trifoliate orange as most hardy.
Temperature plays an important role in the production of high quality fruit. Typical coloring of fruit takes place if night temperatures are about 14° C coupled with low humidity during ripening time. Exposure to strong winds and temperatures above 38° C may cause fruit drop, scarring and scorching of fruits. In the tropics, the high lands provide the best night weather for orange color and flavor.
people; they don’t need to work so hard nor climb to pick the nuts but wait for them to fall. The macadamia nut tree is indigenous to Australia but introduced in Kenya in 1945 to 1948. In Kenya, it grows roughly in the same climate suitable for growing coffee.
The grafted seedling takes 3-4 months to be ready for planting out in the farm. Seedlings are planting out in the field at a spacing of 9m x 9m or 10 m x 10 m or more if the trees are
intercropped with coffee or any other crop e.g. maize; however, if they are being planted as pure orchard, the spacing should be 4m x 10 m or 5 m x 10 m.
Kenya is sitting on a gold mine that if properly utilized would reap huge benefits for the country.
For many years, tea and coffee farming has been the major source of income for thousands of
farmers, however they are now changing tides and switching to macadamia nut farming.
Macadamia has become a lucrative produce all over sudden with a kilo of the nuts selling for
more than a hundred and a grafted seedling price shooting up from 300 to 500 Kenya Shillings.
Between1986 to 2002 the price ranged between 7 to 23 Shillings per kg., and in 2005 it averaged
80 Shillings per Kg.
The Kenya macadamia nut industry is currently made of approximately 900,000 trees of varying ages from one year to 20 years, grown by over 100,000 small scale farmers with an average of 6 -12 trees per grower. Annual production is about 4,000 metric tons of nuts-in-shell. These produce about 800 metric tons of marketable kernels, making the main commercial product. Other by products such as oil, are minimal. Producers get from nuts-in-shell Shillings 92 million per year.
Kenya is the third largest macadamia producer and the second largest exporter of macadamias. Many Kenyan farmers are integrating macadamia trees into their coffee and tea plantations. They view macadamia output as insurance against the uncertainties of weather which affect coffee and tea.
Passion fruit grows in warm to cool climates within altitude ranging from 1200-2000m. above sea level and minimum rainfall of 900mm per annum. The most suitable soil is medium texture (loamy), which are deep and well drained, with PH ranging from 5.5-7.5.
The apricot favors well drained soil but doesn’t like to be too dry especially in the summer. Providing a happy medium between the two will be key to success and it is up to you to judge the type of soil you already have and influence the structure as much as you can. Too light or sandy then pep it up with lots and lots of organic rich material. Too weighty or sluggish then alleviate it with lots of grit, sharp sand and leaf mold.
The soil should be well cultivated and friable; double dig-it over if it has not been cultivated before. Clear away all perennial weeds because the last thing you want is added competition from them when your trees are in settled, and growing.
Prepare a hole large enough to take the roots. Apricots are vigorous growers and you may find the root system larger than that of other trees. Set the tree to the same depth as it was at the nursery previously – examination of the stem should reveal the soil mark still identifiable and this will tell you how deeply it was set in the ground before. In any event the grafting point should sit above the soil level and the roots buried in not less than 2” of soil.
Dry mulches should be used to retain moisture while heavy banana stems should be supported to avoid damage. Old diseased leaves should be removed while de-leafing is important to ensure healthy growth. Harvesting begins after 15-18 months, and a light shiny appearance means that the banana is ready for harvest. Harvesting should be delicate to avoid bruising of the bananas. The bananas should be temporarily stored in a cool, dry place and should be wrapped in banana leaves or grass to avoid bruising. If for export, they should be washed using a disinfectant and might require branding.
Plums are excellent fresh but also make a wonderful jam or jelly. Plums require full sun and well-drained, sandy soil to thrive. They prefer a soil with a pH that ranges from 5.5 to 6.5. It is always a good idea to have your soil tested before planting any fruit tree to be sure that they pH is appropriate. You should also work the appropriate amendments into your soil before planting. Their overall size may also need to be considered. Most plum trees will reach 16 feet at maturity or 14 feet if they are a dwarf variety.
Plums have quite high moisture demands, so they are best planted on good clay or loamy soils. But sites also need to be well drained as plums, and gages in particular, hate waterlogged soils. Add bulky organic matter to sandy or shallow chalky soils prior to planting.
Plant plum trees in well-drained, moderately fertile soil in full sun. Avoid planting in low areas where frost may settle, as the frost will damage your trees. If possible, find a sheltered position, such as a south- or west-facing spot out of the wind. This will help the plum tree set fruit. For grafted trees, keep the graft union 1 inch above the soil line when planting. Dig a hole that is a few inches deeper and wider than the spread of the roots. Set the tree on top of a small mound of soil in the middle of the hole. Be sure to spread the roots away from the trunk without excessively bending them. Space standard-size trees 20 to 25 feet apart. Space dwarf trees 15 to 20 feet apart.
Plums develop their best flavor if left to ripen on the tree. If they feel soft when gently squeezed, they are ripe. Trees will generally need picking over several times. Harvest fruits carefully so as not to bruise them, then eat fresh, destone and freeze, or make the fruits into preserves.
Tamarillo best known by the name tree-tomatoes in Kenya is a fast-growing tree that grows up to 5 meters. Peak production is reached after 1-3 years, and the life expectancy is about 12 years. The tree usually forms a single upright trunk with lateral branches. They produce 1 to 6 fruits per cluster. Plants can set fruit without cross-pollination, but the flowers are fragrant and attract insects. Cross-pollination seems to improve fruit set.
The Tree-Tomato prefers subtropical climate, they grow in many parts of kenya with rainfall between 600 and 4000 millimeters and annual temperatures between 15 and 20 °C. It is intolerant to frost (below -2 °C) and drought stress. It is assumed that fruit set is affected by night temperatures. Areas where citrus are cultivated provide good conditions for Tree-Tomatos. Tree-Tomato plants grow best in light, deep, fertile soils, although they are not very demanding. However, soils must be permeable since the plants are not tolerant to water-logging. They grow naturally on soils with a pH of 5 to 8.5. They are as well planted by irrigation as they also do well.
we graft our seedling with "muthakwa" to ensure our tees are resistant to nematodes, they are drought resistant, mature fast in 9 months compared to other that mature in more than a year. Due to good feeding our fruits are bigger than normal.
A tree is usually kept to 3-6 trunks for fruit production. They tend to sucker around the base. These need to be removed, though they can be used as cuttings for propagation if you chose not to discard them.
Pomegranate is especially well adapted to the environments with cool winters and hot summers, but can be grown in the humid tropics or subtropics, and the plant will survive very well in Kenya. Commercial production is concentrated in dry summer climates, and pomegranate is extremely drought tolerant once established, but crops much better with more generous moisture. Pomegranate thrives on a wide variety of soils and has a high resistance to salinity.
Mango is one of the most important fruit crops in the tropical and subtropical lowlands. The mango industry in Kenya has expanded considerably over recent years, not only in size but also in the geographical location of commercial and homestead plantings. No longer is commercial mango cultivation restricted to the Coast region, as significant plantings of improved cultivars now also exist in the Makueni county, Meru County, Murang’a County, Nairobi County, Nakuru County, Siaya County, Taita Taveta County, Tana River County, Tharaka Nithi County, Bungoma County, Kitui County, Embu County, Machakos County, Kiambu County among other regions. But the generally arid eastern region produces 61 per cent of all mangoes, followed by Rift Valley at 30 per cent and Coast, which produces 28 per cent.
Main characteristics that differentiate varieties are the fruit shape, size, aroma, sweetness, color, fiber
content, taste, seed size and resistance to diseases. Proper selection of a mango cultivar for production must consider the following criteria:
• good adaptation to the local conditions (e.g. rainfall and dry periods)
• alternation of flowering and fruiting
• tolerance to pest and disease infections
• designated use and market requirements
The mango is best adapted to a warm tropical monsoon climate with a pronounced dry season (>3 months) followed by rains. However, information from other countries indicates that crops cultivated for a long time over an extended area show a high degree of diversity due to varied environmental influences.
Varieties include; Apple mango, kent, Haden, Tommy atkins,Van dyke etc
Mangoes are the most popular and full of nutritional and unique taste. its rich in vitamin A,C,E,and K
Peach trees grow best in full sun, where they can bask for at least six hours in the natural light. They prefer slightly acidic soils ranging from 6.0 soil pH to 6.5. Anything slightly under or over and the tree will still grow, but its yield and health may be adversely affected. The trees love sandy loam soil and demand good drainage. If soil drainage is poor, tilling in compost, sand or peat moss helps increase drainage capabilities.
Peach trees require the most water when they're young -- their first year in the ground -- with watering once weekly or, twice weekly. Peach trees may produce fruit during drought-like conditions if not watered, but the tree will become stressed and the fruit will lack size. To maintain soil moisture, add mulch around the tree but not touching the trunk itself.
Peaches can survive in cold winters where temperatures regularly reach zero degrees Fahrenheit, but the next harvest will be small or nonexistent. They thrive in climates where temperatures during winter reach 150C -30 0C degrees.
Peach trees that are expected to grow to a mature height of about 25 feet grow best when they have 20 feet of space between them. Dwarf peach trees thrive when planted about 6 feet apart. Planting trees too close together reduces air circulation and may prohibit growth and result in root damage.
The condition most limiting to growing an avocado tree is cold weather. Hass Avocado varieties are the most cold-hardy, but they can tolerate cold temperatures to only about 20 degrees Fahrenheit. During freezing weather, it helps to drape blankets or tarps over a young tree and anchor the coverings to the ground. If an avocado tree is large, then mounding soil or mulch high on the tree trunk for winter can help the tree survive cold temperatures.
An avocado tree can grow successfully in a variety of soil types and in soil with acidic or alkaline pH levels, but the tree requires soil that has good drainage. It declines in poorly draining and saline soil. Although an avocado tree cannot tolerate wet soil, it needs at least 1 inch of water every week during periods of insufficient rainfall. Not fertilizing the tree until it is 1 year old is recommended. Young trees need four applications of a balanced manure and older trees need twice-yearly applications of a high-nitrogen product applied in early December and late July.
habits as well as their training and trellising requirements. The fruit normally ripens within 25 weeks after the flowers first appear. The fruits range in weight from 40 to 90 g and can be picked shortly after the first frost in autumn; after that, they can be kept in cold storage for 4–6 months at 00 C. Kiwi vines can be grown on a wide range of soil types at elevations ranging from 1000 m to 2500 m.
The kiwi plant is dioecious, meaning individual plants are either male or female. Only female plants bear fruit, but only when pollinated by a male plant. Vines of both sexes are essential for fruit production, and they must flower at the same time to ensure pollination. One male pollinator vine is required for eight female vines. The vines are commonly supported on sturdy structures strong enough to bear the heavy fruit, which might otherwise break the rather weak vines. T-bars or hitching post trellises are recommended to support the large fruiting area in the
form of a canopy and provide easy access to the fruit.
Oranges can be grown from as low as sea level to 200m above sea level. Areas of low humidity are most ideal. Such a climate is important for reduced disease intensity and for acquiring good orange colour. A dry hot day, cool at night climate also favours good color development. Citrus requires temperature ranges from 13oC-38oC. Optimum temperature is 25oC-35oC. Extremely high temperatures may be harmful especially during flowering or if cool temperatures are followed by a hot period. Damage occurs in the form of flower and leaf drop. Wind can also cause serious damage to orange trees and fruits. Hot dry wind will often scorch trees by drying young leaves. Winds of high speeds will scar fruits and cause fruit drop. Where winds are a problem, wind break shelters should be planted
The ideal spot for a mature pawpaw is in a sunny location protected from the wind and endowed with plenty of rich, well-drained soil. The seedling should be protected from direct sunlight for the first year or two, so filter the sun with an open-ended barrel or some netting. After that, full sun is preferred.
Tree Growing papaya trees is generally done from seed that is extracted from ripe fruit. If you are using a fruit from a grocery store, it is most likely going to be a bisexual plant. You should plant several seeds per pot to ensure germination. Under full sunlight, seedlings may emerge in about two weeks. Plants can be set out after they are a foot tall and spaced 8 to 10 feet apart. The seedlings will flower after five or six months.
Pawpaw also grow best in full sun. Papayas like well-drained soil, and because of shallow roots, growing pawpaw trees will not tolerate wet conditions. In addition to proper pawpaw growing conditions, suitable care of pawpaw fruit trees is also important. For pawpaw trees to thrive, they require some fertilizer. Provide young plants fertilizer every 14 days using ¼ pound of complete fertilizer. Fertilize older trees with 1 to 2 pounds of fertilizer once a month. Also, be sure to take a soil sample and amend as necessary.
Grape vines not only produce sweet and versatile fruits, they add an element of drama to a garden or landscape. They are vigorous growers, and with the proper pruning, they will produce fruit with ease and can last longer than 30 years.
The crop prefers warm to hot temperatures; during fruiting, the weather must be sunny and dry. Warm environmental temperatures during fruit ripening, is important in increasing the sugar content of berries while reducing their acidity. This explains why grapes grown under irrigation in hot deserts or semi deserts are sweeter than those from cold humid areas.
The crop can grow in any soil, from sandy to heavy clays but the soil should be deep and well drained. Where the rainfall is scant, supplement it with an irrigation of 500 mm of water during the cropping season. In Kenya, the cropping season is September to March.
Irrigation should be withheld after the long rains so as to force the crop to go dormant.
In August to September, fruit buds form thus it is important to keep the plant healthy and well manured.
There are plenty of health benefits in consuming grapes for they are a rich source of Vitamins- A, C, K and minerals such as iron, copper, manganese.
Soils should be well drained. Wet soils lead to poor aeration and increased incidence of crown rot in apples (Phytophthora cactorum). Generally, rooting tends to be shallow, and wet soils will restrict development, resulting in poor anchorage of the tree and a reduced area of soil from which nutrients can be extracted. Soils with high organic matter contents are normally better structured and allow good rooting.
Irrigation is necessary on dry soils, particularly when establishing and growing young orchards. Trickle irrigation and fertigation are increasingly used. In young orchards fertigation helps increase early tree growth and brings trees into bearing earlier. Sprinkler irrigation can be used to protect the tree buds and fruitlets against frost damage.
Sowing of a grass mulch between the tree rows is common practice, which together with any clippings, helps to increase water holding capacity, infiltration rate, soil aggregation and recycling of nutrients.
Apples prefer a slightly acidic to neutral soil (pH between 5.8 and 7.0). Extreme soil pH values result in nutrient tie-up or toxicity and poor tree and fruit development. It is important to amend the pH in acidic soils by incorporating lime before planting
