Origin and Characteristics of Flax
Flax (Linum usitatissimum L) is one of the oldest crops and has been cultivated for more than 5,000 years in the southern part of Asia and the Mediterranean region. Vavilov, the famous plant scientist, believes that the flax originated from the regions of Afghanistan and Uzbekistan, India, and the Mediterranean (in Spain, Greater Asia, and Egypt) and has been domesticated in the Fertile Crescent. The flax currently grown commercially seems to be the product of natural hybridizations between 2-3 flax plant varieties. Flax is a cool-season plant that belongs to the Linaceae family and the genus Linum, and the modern varieties/types are annual plants. Depending on the type, flax plants can grow in a wide variety of climates and are considered resilient plants.
- Fiber flax: grows a long, unbranched main stem and is taller than the linseed type, reaching 1.5 m.
- Linseed (oil flax): is much shorter (half a meter in height or a little more), with many branches.
The fibers extracted from it are used in many industries, depending on its type, degree of softness, and length.
Nutritional and Industrial Uses
Like other edible oils, the main component of flaxseed oil is fatty acid. Other compounds in flaxseed oil, such as volatile compounds, phenolic compounds, tocopherol, phytosterols, etc., have been detected. Flaxseed oil contains around 96% triacylglycerides (TAG) and 1.4% polar lipids, glycol, and phospholipids. The main TAG in flaxseed oil is trilinoleate (35%).
On the other hand, the seeds can be used as a whole as part of the human diet, offering many health benefits thanks to the Omega 3, α-linolenic acid (ALA) (fatty acid), lignans, proteins (18-23%), and dietary fibers they contain. For this reason, the seeds have been used to help patients with diabetes, cholesterol, and heart problems; at the same time, the oil extracted from the linseeds (30 to 44% oil content) contains high amounts of α-linolenic acid (ALA) and other substances that make it nutritious and with anti-inflammatory effects (it also help in healthy bowel movement). Food products based on flaxseed oil, such as bread, cookies, drinks, ice cream, salad dressings, sausages, egg sticks, yogurts, fat spreads, surimi, cheese, etc.

Cultivation Practices
Flax is a crop with a relatively long cultivation period, reaching up to 100 days. Flaxseed, also known as linseed is a crop usually grown for extracting oil. And fibers of flax are used to make cloth (commonly called linen cloth). Linen cloth is much older than cotton and wool. Its cultivation originated in Europe, centuries ago. Flaxseed is a cold-season crop and is grown in both the northern and southern regions of India.
The flax crop is usually grown after cotton, corn, summer leguminous crops such as soybeans, or oil crops such as sunflowers. It is not planted after rice due to the difficulty of smoothing the seed beds. Growing flax in light clay or heavy yellow soils of homogeneous fertility is preferable. Planting flax should be avoided in lands with high salinity levels or fields with high weed pressure. Flax is a winter crop that requires low temperatures to grow. Newly emerged seedlings (cotyledon stage) can tolerate temperatures down to -2 to -4 °C (25 to 28 °F). Plants at the two-leaf stage can tolerate up to -5.5 to -8 °C (18 to 22 °F).
Planting Methods
Flax roots go deeper into the soil, so prepare the land by proper deep plowing. 2-3 ploughings can be done. The required seed rate for this crop is 30-40 seeds kg/ha. And seeds can be sown according to the line sowing method with uniform distribution. And seeds must be placed 4-5 cm below the soil. Spacing between each row can be kept as 20-30 cm and between each crop can be kept as 10 cm.
- The seeds are scattered in the ground in two perpendicular directions to ensure uniform distribution.
- The use of row seeders in flax cultivation is the ideal, modern method to ensure that the seeds are well distributed in the field and at fixed distances of 7.5-20 cm (drill spacing). For no-till systems, a row distance of 30 cm can be chosen. In dry years or in fields with high weed pressure, farmers may choose a 70-90 cm row planting distance. This provides good plant growth and produces robust plants (of desirable thickness and strong stems). The thickness of the stem ranges from 1.5 - 3.0 cm.
Seed Rate
- In clay soils: Using a seed rate of 40-60 kg/hectare when planting using row seeders and 70 kg when planting using the scattering seed method is recommended for local dual-purpose varieties.
- In sandy soils: Flax is sown at a lower seed rate due to the high germination rate flax has in such soils because there are no barriers compared to clay soils. Irrigated fields may support a higher seeding rate. In late sowing, it is also important to use higher seed rates.
Irrigation
The moisture level must be good as this crop requires more moisture. Make sure moisture is maintained in the germination phase and in each development phase, so proper irrigation practices must be done. The irrigation process (planting irrigation) must be done slowly in the broadcasting planting to reduce the seeds drifting and gathering in low places due to water flow, negatively affecting seed distribution, crop emergence, and homogeneity. Flax needs 5-6 irrigations in clay soils during the growing season. The period between one irrigation and the next ranges from 20-25 days and may be longer than that in the event of heavy rain. It should also be taken into account that the irrigation during planting should be slow (avoid high pressure that will create a strong flow and soil disturbance) so that there is no drifting of the seeds, especially in the case of broadcasting planting. It is also necessary to be careful with the irrigation timing and avoid applying it in windy weather (important for overhead irrigation) during the seed growth stage to decrease the risk of occurrence of lodging and the accompanying increase in the percentage of unfilled capsules.
Plants must not experience drought stress to obtain a high seed yield. In the case of sprinkler irrigation, it is recommended that the irrigation process be carried out every 3-4 days, depending on the type of soil and the weather conditions, due to the difficulty of these soils retaining water for a long time.

Fertilization
Use FMY (farmyard manure) at the time of land preparation. If the soil does not have sufficient nutrients, then feeding with micronutrients will be a good idea. Phosphate fertilizer is added to flax during service operations at a rate of 100 kg (single superphosphate or triple superphosphate). Flax also responds well to nitrogen fertilization in the range of 45-55 nitrogen units, depending on soil fertility and the previous crop, to obtain a high yield of straw, seeds, and high-quality fiber. Excessive nitrogen fertilization also leads to plant lodging and a decrease in the quantity and quality of the crop. Nitrogen fertilizer is added with broadcasting in three equal batches (the first before the initial irrigation - the second before the second irrigation - and the third before the third irrigation), provided that the fertilizer is added at the end of the day immediately preceding irrigation so that a portion of the nitrogen is not lost through volatilization, decreasing the environmental pollution due to runoff and nutrient leakage.
Flax needs higher rates of phosphate fertilizer in light soils than in clay. More specifically, 150 kg of single superphosphate fertilizer or the equivalent triple fertilizers are needed per acre. Urea fertilizers are best to be avoided as a nitrogen source for flax crops. In the case of flood irrigation in sandy soils, the nitrogen fertilizer is added in four equal batches, provided that fertilization is done every 15 days and immediately before irrigation.
Weed Control
Flax plants could "suffer" from broad-leaf and narrow-leaf annual winter weeds. The manual tillage of flax weeds must be carried out in the early stages of growth if they are few so as not to cause mechanical damage to the plant. If the weeds are dense, they must be controlled using herbicides. The best time for chemical control is when the length of the plants is between 12 and 15 cm at most and there is moderate soil moisture to avoid damaging the flax plants or reducing the efficiency of the pesticides.
Pests and Diseases
Termite, cutworm, wireworm, semi looper, leaf minor, bud fly, pasmo, aster yellows, gram pod borer are some of the pests and diseases which can harm the flax crops.
Diseases:

- Flax seedling blight and root rot: It leads to failure of seed germination or the seedling's death as soon as they appear on the soil's surface.
- Powdery mildew: A common first symptom of the disease is the formation of small white spots on the underside of the leaves. Then, these spots merge and increase in area until they spread to all parts of the vegetative system.
- Flax rust: The infection appears in the form of orange pustules on the underside of the leaves and then appears on the upper side, too. Seed capsules and stems can be infected. At the end of the season, the color of the pustules turns brown.
Pests:
- Aphids: The infestation appears in the middle of the plant's life and increases at the edges of the field and in areas with weeds.
- The flax fruit worm (the nematode bug): The green-colored larvae feed on the flax seeds inside the capsules until the fruits are empty/hollow.
Harvesting
Flaxseed crop starts maturing by the end of February and depends upon winter conditions and the time of sowing. When leaves are dry and balls turned brownish, the flax crop is ready to harvest. It is recommended to harvest flax when the color of the capsule turns pale yellow, regardless of the color of the stems or the leaf's senescence. The harvesting process must take place early in the morning. Harvesting is done manually or mechanically by taking a group of plants, wrapping them, and removing them from the ground. Then, the stems are placed on the ground so the roots are in one direction and the fruits are in the other. Then, the tying process is carried out by creating bundles with a diameter of 15 cm each in the area of the lower one-third of the stem. They are transported to the warehouse, and the bundles are then placed in piles with the capsule facing up to expose it to the sun, making it easier to separate the seeds from the capsules.
The average yield of a crop varies from 210-450 kg/ha of seed. And the irrigated crop yield can range from 1,200-1,500 kg/ha. Flaxseeds can be sold to oil manufacturing industries and flax fibers to Linen manufacturing industries.
Health Benefits for Nigerian Women
The benefits of flax seeds for Nigerian moms and moms-to-be are powerful and often overlooked. As someone passionate about natural health solutions, I’ve learned that Nigerian women’s bodies go through incredible stress, from managing multiple responsibilities to hormonal fluctuations from adolescence through motherhood and beyond.
Lignans are a type of phytoestrogens (a natural estrogen sources that mimic estrogen in our bodies). Think of them as nature’s hormone regulators. When estrogen levels drop, phytoestrogens can step in to help restore balance. When estrogen levels are too high, they help regulate them down.
Key Benefits:
- Flax seeds contain powerful lignans that work like gentle, natural hormone regulators, especially for menstrual health.
- These omega-3-rich seeds can help decrease the growth of harmful cells, particularly in hormone-sensitive areas.
- If you’re dealing with endometriosis, fibroids, or other inflammatory conditions (which affect many Nigerian women), flax seeds as natural anti-inflammatory foods could be your new best friend.
- Digestive health!
- For our mamas entering or going through menopause, flax seeds can be incredibly supportive during this transition. The beauty of flax seeds is how easily they blend into our everyday Nigerian meals!
Practical Tips for Incorporating Flax Seeds
I understand the struggle of finding authentic natural health supplements in Lagos and across Nigeria, from fake supplements to overpriced imported goods.
Dosage: Start with 1 tablespoon daily and gradually increase to 2 tablespoons.
Medication Absorption: Flax seeds may slow absorption of medications.
Expected Results: Most women notice improvements in menstrual symptoms within 2-3 cycles.
Nigerian women carry incredible strength and resilience, managing families, careers, communities, and dreams. You deserve to feel strong, healthy, and balanced throughout every phase of life. These tiny seeds prove that the best solutions are often the simplest ones. Remember, small consistent steps lead to significant transformations.
