Paddy fields also known as flooded fields are the best fields for rice cultivation, though irrigation methods are also used.Some beans species such as red, kidney, and butter beans are poisonous when undercooked, shallow-fried or slowly cooked.Cassava is a major source of carbohydrates for humans and animals, most especially in the tropics.Maize is also known as corn. Its total production surpasses that of any other grain such as rice or wheat.A plantation is a large-scale farm that specializes in cash crop production or wood production.White and Brown rice are the most available types.Beans are the major source of plant proteins for humans.Nigeria is the World's largest producer of Cassava.Yellow corn is the most popular variety of Maize. Other types include sweet corn, flint corn, pod corn, and dent corn.Such crops include Cotton, Coffee, Cocoa, Tea, Sugarcane, Oil palm, Oil seed, Rubber, Fruits, Tobacco, and so on.According to FAO, Nigeria and Egypt are among the top rice producers in Africa.Beans contain soluble fibers which help lower blood cholesterol level.Tapioca is the raw powdery extract from Cassava while Garri is obtained from grated Cassava, lightly fried in palm oil to preserve them and to increase their market value.Maize is a versatile crop. It thrives in cold, hot, dry or wet conditions, though it performs better on moist soil.Tree plantations are essential for wood production.Brown rice has more proteins than White rice but it contains less carbohydrate than White rice.Tanzania is the largest producer of beans in Africa.Bitter Cassava contains more cyanide than Sweet Cassava but it is more pest-resistant.Planting of Maize is usually done in rows which allows for planting of other crops between the rows in order to maximize land use.Wood productions from Tree plantations are generally higher than those from natural forests.Improved rice breeds are obtained through genetic engineering. For example, perennial rice breeds are currently underway, and Golden rice, which has a high vitamin A content is already available.Beans have numerous varieties, up to thirty or more, most of which grow insides pods.Besides being a perennial crop, Cassava is drought-tolerant, thrives in poor soil and with low rainfall.Maize is highly water-efficient. It is a C4 plant, hence it has a higher photosynthetic efficiency compared to C3 plants such as rice.Forest trees help minimize greenhouse effect through carbon (IV) oxide sequestering.Through scientific research, various other types of rice such as flood-tolerant, drought-tolerant, salt-tolerant, and environment-friendly rice have been developed.Beans need warm temperature for adequate growth.Cassava is used for producing biofuel, laundry starch, flour, cake, cookies and so on.Both low-till and no-till farming techniques are used in Maize farming.Tree plantations are not reliable in reducing greenhouse effect since the sequestered carbon (IV) oxide is eventually released when the trees are harvested.Due to its cyanide content, raw Cassava is a pesticide, and causes serious neurological disorders in humans.Commercial farming of Maize is often done with a planter.Plantations are devoid of decaying dead wood, which are mostly found in natural forests ecosystems.Cassava is highly digestible. It contains mostly water and carbohydrate, but it also contains Vitamin C and minute protein.Maize harvesting in a large field is done with mechanical pickers and corn binders.Forest reserves and plantations essential for wind breaks, erosion control, and landslide stabilization.Cassava processing leads to the discharge of cyanides into effluents. This results to environmental pollution if poorly handled.Harvested Maize grains are dried using grain driers to sufficiently reduce the moisture content of the grains.Location of plantation sites must be properly assessed to favour biodiversity and wildlife conservation.Acute cyanide intoxication (from sources like cassava) is a major cause of goitre. It is treated with an injection of thiosulfate which detoxifies by converting the cyanide to into thiocyanide.Dried maize grains are stored in silos or bins.Rubber plantations are the major source of latex, the raw material used for making tyres, elastomers, adhesives, and so on.Post-harvest losses such as PPD is the major setback towards exportation of Cassava.Maize is used for producing starch, adhesives, fabrics, plastics, biofuel, and so on.Cotton obtained from Cotton plantations is widely used in the textile industry.Plant breeding methods such as cloning, irradiation with gamma rays, has resulted in PPD-tolerant Cassava.The Market price of Maize for food is affected by the use of Maize for biofuel production.Oil palm plantation thrives in wet tropical regions.Sugarcane plantations are essential for the production of cane sugar.Tree plantations ensure that humans do not exhaust trees in natural forest plantations by providing enough wood for timber, paper and pulp industries.
