Brachiaria Deflexa
''Brachiaria deflexa'' (Guinea millet) is a annual millet grass belonging to the grass family (Poaceae). It is native to many regions such as Africa, India, and Pakistan in both tropical and subtropical regions. It has been used as a supplemental food source among other cereal crops. Description ''Brachiaria deflexa'' is an annual grass that grows up to 70 cm tall. It has weak and slender stems that are finely pubescent. The stem extends into roots at the lower nodes. Leaves alternate across the stem and are a linear-lanceolate shape with a pale leaf sheath. Inflorescence imitates a panicle with 7-15 racemes on a 6 cm-15 cm long axis. These racemes are 2 cm-20 cm long, broadly elliptical (2mm-3.5mm), and have spikelets up to 15mm long. It matures in 90–130 days and flowers throughout the year. ''Brachiaria'' is a C4 species, which is advantageous in its dry and often highly sunlit conditions. Geographic distribution and growth Guinea millet is be ...

Annual Plant
An annual plant is a plant that completes its life cycle, from germination to the production of seeds, within one growing season, and then dies. The length of growing seasons and period in which they take place vary according to geographical location, and may not correspond to the four traditional seasonal divisions of the year. With respect to the traditional seasons, annual plants are generally categorized into summer annuals and winter annuals. Summer annuals germinate during spring or early summer and mature by autumn of the same year. Winter annuals germinate during the autumn and mature during the spring or summer of the following calendar year. One seed-to-seed life cycle for an annual plant can occur in as little as a month in some species, though most last several months. Oilseed rapa can go from seed-to-seed in about five weeks under a bank of fluorescent lamps. This style of growing is often used in classrooms for education. Many desert annuals are therophytes, be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Digitaria Exilis
''Digitaria exilis'', referred to as findi or fundi in areas of Africa, such as The Gambia, with English common names white fonio, fonio millet, and hungry rice or acha rice, is a grass species. It is the most important of a diverse group of wild and domesticated ''Digitaria'' species known as fonio that are harvested in the savannas of West Africa. The grains are very small. It has potential to improve nutrition, boost food security, foster rural development and support sustainable use of the land. Despite its valuable characteristics and widespread cultivation, fonio has generally received limited research and development attention, which is also why the species is sometimes referred to as an underutilized crop. The name (borrowed by English from French) is from Wolof ''foño''. Fonio has continued to be important locally because it is both nutritious and one of the world's fastest growing cereals, reaching maturity in as little as six to eight weeks. It is a crop that can be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Millets
Millets () are a highly varied group of small-seeded grasses, widely grown around the world as cereal crops or grains for fodder and human food. Most species generally referred to as millets belong to the tribe Paniceae, but some millets also belong to various other taxa. Millets are important crops in the semiarid tropics of Asia and Africa (especially in India, Mali, Nigeria, and Niger), with 97% of millet production in developing countries. This crop is favored due to its productivity and short growing season under dry, high-temperature conditions. Millets are indigenous to many parts of the world. The most widely grown millets are sorghum and pearl millets, which are important crops in India and parts of Africa. Finger millet, proso millet, and foxtail millet are also important crop species. Millets may have been consumed by humans for about 7,000 years and potentially had "a pivotal role in the rise of multi-crop agriculture and settled farming societies." Descri ...

Grasses Of Africa
Poaceae () or Gramineae () is a large and nearly ubiquitous family of monocotyledonous flowering plants commonly known as grasses. It includes the cereal grasses, bamboos and the grasses of natural grassland and species cultivated in lawns and pasture. The latter are commonly referred to collectively as grass. With around 780 genera and around 12,000 species, the Poaceae is the fifth-largest plant family, following the Asteraceae, Orchidaceae, Fabaceae and Rubiaceae. The Poaceae are the most economically important plant family, providing staple foods from domesticated cereal crops such as maize, wheat, rice, barley, and millet as well as feed for meat-producing animals. They provide, through direct human consumption, just over one-half (51%) of all dietary energy; rice provides 20%, wheat supplies 20%, maize (corn) 5.5%, and other grains 6%. Some members of the Poaceae are used as building materials (bamboo, thatch, and straw); others can provide a source of biofuel, ...

Vernonia Galamensis
''Vernonia galamensis'' is a plant in the sunflower family, known for its use as an oilseed. This species, often called ironweed, is the largest source of vernonia oil, which is rich in a useful epoxy fatty acid called vernolic acid and is used to make plastics, rubbery coatings, and drying agents. Use of this oil as a replacement for traditional plasticizers and binders in the production of paints and PVC shows promise as a method of reducing smog pollution. One of over 1,000 species in genus ''Vernonia'', ''V. galamensis'' is native to East Africa. It is grown in the region as an industrial oilseed. Its seed production is poor when it is grown outside of the equatorial region, so cultivation in other places is not always economically worthwhile; however, further studies in the breeding of this species to generate more productive varieties may show promise. It requires loose, porous soil and long periods of dry conditions. It is grown in many parts of Ethiopia, especial ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Euphorbia Heterophylla
''Euphorbia heterophylla'', also known under the common names of Mexican fireplant, painted euphorbia, Japanese poinsettia, paintedleaf, painted spurge and milkweed, is a plant belonging to the Euphorbiaceae or spurge family. Distribution ''Euphorbia heterophylla'' is native to tropical and subtropical America but is now widespread throughout the tropics. Many herbicides fail to control it and hence it has spread rapidly in many parts of the world. This plant has been introduced to South and Southeast Asia as an ornamental plant, having become a weed in India and Thailand, where it has invaded cotton fields and other agricultural terrain. Description Euphorbia heterophylla grows between 30 and 100 cm tall and has hollow stems that may be branched or simple with angular ribs. The leaves of the plant have variable shapes within and between populations. The lower leaves are alternate whereas the upper leaves are opposite and commonly have a whitish or bright red base.

Cowpea
The cowpea (''Vigna unguiculata'') is an annual herbaceous legume from the genus ''Vigna''. Its tolerance for sandy soil and low rainfall have made it an important crop in the semiarid regions across Africa and Asia. It requires very few inputs, as the plant's root nodules are able to fix atmospheric nitrogen, making it a valuable crop for resource-poor farmers and well-suited to intercropping with other crops. The whole plant is used as forage for animals, with its use as cattle feed likely responsible for its name. Four subspecies of cowpeas are recognised, of which three are cultivated. A high level of morphological diversity is found within the species with large variations in the size, shape, and structure of the plant. Cowpeas can be erect, semierect ( trailing), or climbing. The crop is mainly grown for its seeds, which are high in protein, although the leaves and immature seed pods can also be consumed. Cowpeas were domesticated in Africa and are one of the oldest c ...

Sahel
The Sahel (; ar, ساحل ' , "coast, shore") is a region in North Africa. It is defined as the ecoclimatic and biogeographic realm of transition between the Sahara to the north and the Sudanian savanna to the south. Having a hot semi-arid climate, it stretches across the south-central latitudes of Northern Africa between the Atlantic Ocean and the Red Sea. The Sahel part of Africa includes – from west to east – parts of northern Senegal, southern Mauritania, central Mali, northern Burkina Faso, the extreme south of Algeria, Niger, the extreme north of Nigeria, Cameroon and Central African Republic, central Chad, central and southern Sudan, the extreme north of South Sudan, Eritrea and Ethiopia. Historically, the western part of the Sahel was sometimes known as the Sudan region (''bilād as-sūdān'' "lands of the Sudan"). This belt was located between the Sahara and the coastal areas of West Africa. There are frequent shortages of food and water due to the dry h ...

Bamana Empire
The Bamana Empire (also Bambara Empire or Ségou Empire, bm, italics=no, ߓߊ߲ߓߊߙߊ߲߫ ߝߊ߯ߡߟߊ, Banbaran Fāmala) was a large West African state based at Ségou, now in Mali. This state was established after the fall of the Mali Empire and the Keita dynasty, as a smaller Bambara Empire founded by other Bambara families related to the Keita clan. It was ruled by the Kulubali or Coulibaly dynasty established c. 1640 by Kaladian Coulibaly also known as Fa Sine or Biton-si-u. The empire existed as a centralized state from 1712 until the 1861 invasion of Toucouleur conqueror, El Hadj Umar Tall. History Coulibaly dynasty In around 1640, Fa Sine became the third Faama ( Mande word for King) of a small kingdom of Bambara people in the city of Ségou in Mali. Though he made many successful conquests of neighboring tribes and kingdoms, he failed to set up a significant administrative framework, and the new empire disintegrated following his death (c. 1660).

Songhai Empire
The Songhai Empire (also transliterated as Songhay) was a state that dominated the western Sahel/Sudan in the 15th and 16th century. At its peak, it was one of the largest states in African history. The state is known by its historiographical name, derived from its leading ethnic group and ruling elite, the Songhai. Sonni Ali established Gao as the capital of the empire although a Songhai state had existed in and around Gao since the 11th century. Other important cities in the empire were Timbuktu and Djenné, conquered in 1468 and 1475 respectively, where urban-centered trade flourished and to the south is the north Akan state of Bonoman. Initially, the empire was ruled by the Sonni dynasty (–1493), but it was later replaced by the Askia dynasty (1493–1901). During the second half of the 13th century, Gao and the surrounding region had grown into an important trading center and attracted the interest of the expanding Mali Empire.
