The kenaf fiber needs to be treated properly to remove the lignin. The tensile strength of the kenaf fiber is about 800 MPa, which makes it suitable natural fiber in engineering applications. [8] The core is about 60% of the plant and has fibre cells that are thick (≈38 μm) but short (0.5 mm) and thin-walled (3 μm). [9]
Production of some products is highly concentrated in a few countries, China, the leading producer of wheat and ramie in 2013, produces 95% of the world's ramie fiber but only 17% of the world's wheat. Products with more evenly distributed production see more frequent changes in the ranking of the top producers.
Fiber crops are field crops grown for their fibers, which are traditionally used to make paper, cloth, or rope. [1] Philippine natural fibers. Fiber crops are characterized by having a large concentration of cellulose, which is what gives them their strength. The fibers may be chemically modified, like in viscose (used to make rayon and ...
R. taedigera is the source of raffia fibers, which are the veins of the leaves, and this species produces a fruit called "brazilia pods", "uxi nuts" or "uxi pods". [ 3 ] They grow up to 16 metres (52 ft) tall and are remarkable for their compound pinnate leaves , the longest in the plant kingdom; leaves of R. regalis up to 25 metres (82 ft ...
A farmer and his cow. The majority of herders in African countries are livestock owners. Livestock farming is a part of Nigeria's agriculture system. In 2017, Nigeria had approximately over 80 million poultry farming, 76 million goats, 43.4 million sheep, 18.4 million cattle, 7.5 million pigs, and 1.4 million of its equivalent. [26]

The main crops grown in the region are millet, sorghum, and cowpea, while groundnut and sesame are significant minor crops. [10] Wild foods also serve as an important supplement to the diet, especially during times of food shortage. [10] The bulk crops are grown during the rainy season which begins in June or July, [6] when the temperature is warm.
Deforestation in Nigeria. Deforestation and habitat loss: Deforestation is a major threat to Nigerian lowland forests. [65] The expansion of agriculture, particularly for the cultivation of cash crops like oil palm, cocoa, and rubber, has led to extensive clearing of forested areas.
