The onion ( from Latin cepa “onion”), also known as the bulb onion or common onion, is a vegetable and is the most widely cultivated species of the genus Allium. Its close relatives include the garlic, shallot, leek, and chive. The onion plant has a fan of hollow, bluish-green leaves and its bulb at the base of the plant begins to swell when a certain day-length is reached. The bulbs are composed of shortened, compressed, underground stems surrounded by fleshy modified scale (leaves) that envelop a central bud at the tip of the stem. Major types of onions farmed in Kenya are bulb onions and spring onions, Bulb onions; take 3 to 4 months to reach maturity. Short rains are great for bulb onions since they can be harvested between January and February. After the long rains of March, the price of these onions hike and farmers who harvest after these period make good profit margins. Spring onions; are easy to plant, you can even plant them at your kitchen garden. They are commonly used in vegetable salads or as seasoning in soups. Some of the health benefits of spring onions include lower blood sugar and decreasing blood pressure and cholesterol levels. Of the two types, bulb onions are more popular than the spring ones due to their long shelf life and sweet taste. Currently, there are two different varieties of bulb onions in the market. There is the small, thin and firmly layered onion that has a strong pungent smell from Tanzania. The second one is the big loosely held variety that is grown locally, in Kenya. Onions are categorized according to the color, size and shape. Onions can be harvested while still young; there is a perennial type of onion which is rarely attacked by insects or diseases. The onions can be planted by direct seed or by transplanting. The seedling stage requires planting of seedling in a seedling bed, the soil of the bed should be loose which takes 6 weeks for them to be ready for transplant. Transplanting method has a higher rate of succeeding than direct seeds; onions grow well in raised beds or rows at least 4 inches high, the onion should go 4 inches deep only a third of the bulb should be underground, if the onion is deeply planted the growth of the bulb will be restricted. The width between each onion should be 5 inches; the rows should be 12 to 17 inches apart. Select an open garden when planting to avoid being shaded by other plants. The soil should be loose and rich in nitrogen, compact and hard soil will interfere with bulb development, mix the soil with some nitrogen fertilizer at the time of planting, side dress the onion after every two weeks, make sure you repeat the dressing after every two weeks until the onion starts to bulb. How to Plant: To get the best results with onions you need to start them in a Nursery. Here is how to do this; Make a raised nursery bed 1 metre wide and any desired length. Apply well decomposed manure at a rate of 15kg per square metre. Mix and Apply DAP fertilizer at a rate of 20 grams per metre square Make shallow furrows 15 cm apart. Mix the seeds with dry ash, sand or soil at a ratio of 1:3 to help spread the small seeds. Plant the seeds and cover lightly with soil and apply mulches ( Grass or Polythene cover spread over the soil on the nursery bed) After planting irrigate the nursery bed liberally for the first 10 days and continue watering regularly. Germination of seeds will take about 7-10 days after which the mulches are removed and used to make a shade above the tender plants which have not fully developed. Transplanting of the seedlings takes place 6 weeks after planting seeds in the nursery. Transplant when the seedlings have pencil thick base and a height of approximately 15cm. Seedlings should have 3 to 5 well formed leaves at transplanting time. Two weeks before transplanting reduce the shade to improve seedling survival rate in the field. It takes about 4 months for onions to mature Conditions for Onion Farming Onions perform well in well drained, fertile, sandy loam, non-compacted soils. The ideal pH is 5.8 to 6.8. Onion farming is a worthy venture since it’s possible to grow onions throughout the year via irrigation. Soil test with accredited laboratories is advised. The ideal temperatures onions need to grow are between 13 – 35 degrees centigrade. This means that onions can grow in most parts of Kenya. In terms of requirements, apart from land that is an obvious fact, other requirements are DAP Fertilizer and seedlings. 1 kg of seedlings can be used in 1 acre while 20 grams of DAP Fertilizer is applied per square meter. You should note that there are different seed varieties and they perform differently under different conditions. Common hybrid varieties available in Kenya include Red Creole, Red Pinnoy, Jambar 1 and Red Bombay. The most popular seed variety in Kenya is the Jambar F1 since it produces high yield and the size of its onions are bigger. Challenges facing Onion Farming in Kenya Rains or Excess Watering: Too much rains or excess watering can water log the crop. If the rain in your area is too much, focus on growing the crop during the short rains. You can also raise the beds to ensure the water flows out of the field. Avoid excessive watering of your onions. The best type of

THE BENEFITS OF GROWING CROPS IN A GREENHOUSE Over time, farmers have come to realize that there are plenty of benefits of growing plants in a greenhouse, especially with the uncertainty in climate change lately. However, before you carry out your greenhouse farming in Kenya, you have to conduct adequate research to ensure that you will reap some of the following benefits. A greenhouse delivers an extended growing season There are consistency and reliability in food production You can plant a variety of crops in a greenhouse It allows you to control the growth environment, humidity levels, and soil easily A greenhouse makes it easy for you to control insect and animal infestation Factors to consider for greenhouse onion farming The variety of the onion crop. The climatic conditions of the onions. Agronomist practices required by onions. Irrigation method. Availability of the market. Pests and disease management The variety of onions The variety of onions depends mainly on the type of climatic and the soil factors. The commonly used varieties may include;  Neptune F1 variety Bombay red. Red coach F1 Russet F1 Quantifying onion seed for greenhouse onion farming Quantifying seed required for planting depends on land availability by the farmer. The standard seed required by a greenhouse of 8 meters by 30 meters is approximately 250mg. This quantity is good enough to plants six beds of one meter each with a running length of 30 meters. The numbers of seedlings that can accommodate in a single bay of a greenhouse is roughly 50,000 seedlings thus the 3 months output in terms of kilogram are 3000kgs-5000kgs. These kilograms when translated into Kenyan shillings per kilograms comes to about ksh150, 000 to ksh250, 000 Irrigation methods of greenhouse onion farming Drip irrigation system The commonly used method of irrigation of onion farming is the drip irrigation. Drip irrigation system commonly used for onion farming are drip line of 10 centimetres, 15 centimetres and 20 centimetres. These spacing dictate the onion spacing along the rows and the column. The GAP ( Good Agricultural Practices) in Kenya recommends these spacing from plant to plant and 30 centimetres from one line to another. Benefits of best drip irrigation system The drip irrigation system is the most efficient method of irrigation. Through emitters, water is directly delivered to the plant root zone hence economical on water usage. In the best drip irrigation system, there is a constant benefit of water supply in small quantities to the plants. This creates an ideal moist condition for proper growth of most plants. The best drip irrigation system minimizes weed growth since water is only supplied to a particular crop root. The best drip irrigation system helps in the control of fungal diseases which grow very fast under moist conditions. Timeliness and labor-saving. In the best drip irrigation system, the control valves can be managed by one personnel. One person operates the whole system thus minimizing the labor costs. This minimizes production cost. Ease in fertilizer application. , method of liquid fertilizer application (Fertigation) is very easy and fast. Since water emitters are used to directly distribute fertilizers to particular crop/plants Disease and pest management and agronomy practices Thrips are tiny insects that have onions as most preferred host crop on hot and dry weather conditions. They feed by sucking the plant sap hence opening the onions to attack by diseases like purple blotch. They mostly cause great damage to younger onions when bulbs are forming than older ones hence control measures should be undertaken during early stages of growth. Thrips can cause economic loss by reducing yields by up to 60% if not controlled timely. Symptoms: They cause silvery streaks or patches on the leaves while severe infestation and feeding can result in minute black “tar” like sports on leaves. Younger plant leaves show brown tips and eventually a white color as a result of feeding by thrips. This reduces ability of plants to make food thus resulting in small undeveloped bulbs. The presence of thrips can also be indicated by the black dotted patches of thrips fecal materials produced during their feeding on the onion plant.

The major types of onions farmed in Kenya are bulb onions and spring onions. The best areas suited for farming include Karatina, Oloitoktok, Naivasha, Kieni, Emali, and Mai Mahiu. Bulb onions take 3 to 4 months to reach maturity. Short rains are great for bulb onions since they can be harvested between January and February. Local farmers benefit during this period due to low onion supply from Tanzania, leading to higher prices post-harvest after the long rains in March. Spring onions are easy to plant and can be grown even in kitchen gardens. They are commonly used in vegetable salads or as seasoning in soups. Some health benefits of spring onions include lowering blood sugar and decreasing blood pressure and cholesterol levels. Of the two types, bulb onions are more popular due to their long shelf life and sweet taste. Currently, there are two varieties of bulb onions in the market: the small, thin, and firmly layered onion from Tanzania with a strong pungent smell, and the big, loosely held variety grown locally in Kenya. Conditions for Onion Farming Onions perform well in well-drained, fertile, sandy loam, non-compacted soils with an ideal pH of 5.8 to 6.8. Onion farming is a worthy venture since it’s possible to grow onions throughout the year via irrigation. Soil testing with accredited laboratories is advised. Optimal temperatures for onion growth are between 13 to 35 degrees Celsius, allowing cultivation in most parts of Kenya. However, to maximize production in areas such as Ukambani and parts of the Coastal region, investment in greenhouses and drip irrigation is necessary. Greenhouses optimize temperatures, and irrigation provides the much-needed water. Onions are a cool-season crop, and most areas in Ukambani and the Coastal region are extremely dry. Essential requirements include land, DAP fertilizer, and seedlings. One kilogram of seedlings can be used per acre, while 20 grams of DAP fertilizer is applied per square meter. Different seed varieties perform differently under various conditions. Common hybrid varieties available in Kenya include Red Coach F1 and Malbec F1, with Red Coach F1 being the most popular due to its high yield and the size and color of its onions, which are ideal for the Kenyan markets. Challenges Facing Onion Farming in Kenya Excessive Rainfall or Watering: Heavy rainfall or excessive watering can lead to waterlogging. Focus on cultivating during short rains or raising beds to ensure proper drainage. Drip irrigation is recommended to prevent fungal diseases associated with overhead watering. Diseases: Common diseases affecting onions include Downy Mildew, Bacterial Soft Rots, Pink/White Root, Botrytis, and Rusts. Use effective fungicides to combat these diseases. Pests: Common pests that attack onions include maggots, thrips, nematodes, and leaf miners. Employ quality pesticides to manage pest infestations. Weeds: Weed control is crucial in onion farming. Weeds are a big challenge and should be managed effectively. Optimizing Drip Irrigation for Onion Farming Drip irrigation is the most efficient way to water onion crops, ensuring consistent moisture levels while preventing fungal diseases. Here are some tips to optimize drip irrigation for your onion farm: Design a Proper Layout: Ensure your drip irrigation system is well-designed with emitters placed close to the base of each onion plant for efficient water delivery. Use Pressure Regulators: Maintain consistent water pressure to ensure even distribution across your field. Schedule Irrigation: Water onions early in the morning or late in the evening to minimize evaporation and water loss. Monitor Soil Moisture: Use soil moisture sensors to avoid over or under-watering. Regular Maintenance: Check for clogs and leaks in the drip lines regularly to ensure the system operates efficiently. Fertilizer Application: Use fertigation (applying fertilizer through the irrigation system) to provide nutrients directly to the root zone, enhancing growth and yield. Harvesting Onions The best time to harvest onions is during the dry season. Keep a calendar and record essential dates to ensure timely harvesting. Bulb onions are ready for harvest once they form a shiny membranous cover around the bulbs or when the foliage withers. Spring onions are ready for harvesting when they are 15 centimeters tall and 1.5 centimeters thick. Harvest by pulling the bulbs and chopping off the leaves. Dry the bulbs in the sun before storing the produce.
