[50] CPMV is stable and easy to propagate to a high yield, making it useful in vector development and protein expression systems. The objectives of the study were to The seeds can be harvested after about 100 days or the whole plant used as forage after about 120 days. [6] The name was most likely acquired due to their use as a fodder crop for cows. [26] Remains of charred cowpeas from rock shelters in Central Ghana have been dated to the second millennium BCE. [34], Storage of the seeds can be problematic in Africa due to potential infestation by postharvest pests. Walp.) Background Cowpea (Vigna unguiculata L.) is an important grain and forage legume grown throughout sub-Saharan Africa primarily by subsistence farmers on poor, drought prone soils. Background 5 2.1.4. It is a high protein food and forms a … Brazil is the world's second-leading producer of cowpea seed, accounting for 17% of annual cowpea production, although most is consumed within the country. Vigna unguiculata is a member of the Vigna (peas and beans) genus. The ideal soils are sandy and it has better tolerance for infertile and acid soil than most other crops. Background to the Study Cowpeas ( Vigna unguiculata and Vigna Senensis ) are important grain legumes in East and West Africa as well other developing countries (Dovlo et al . BACKGROUND AND MOTIVATION OF THE STUDY Cowpea (Vigna unguiculata(L.) Walp) is an indigenous African legume crop that is widely cultivated in the semi-arid tropical regions of Asia, Oceania, Africa, the Middle East, southern United States of America and Central and South America (Singh et al.2002). Estimating world cowpea production is rather difficult, as it is usually grown in a mixture with other crops, but according to a 1997 estimate, cowpeas are cultivated on 12.5 million hectares (31 million acres) and have a worldwide production of 3 million tonnes. [59] Cowpeas can be prepared in stews, soups, purees, casseroles and curries. Background. [60][61] They can also be processed into a paste or flour. Generally, 133,000 seeds are planted per hectare (54,000/acre) for the erect varieties and 60,000 per hectare (24,000/acre) for the climbing and trailing varieties. The timing of planting is crucial, as the plant must mature during the seasonal rains. [21] Flower colour varies through different shades of purple, pink, yellow, and white and blue. [21], Compared to most other important crops, little is known about the domestication, dispersal, and cultivation history of the cowpea. However, field trials confirming the benefits of microbes in large-scale applications using economically viable and efficient inoculation methods are still scarce. Higher meat prices during recent years and the need for protein- rich foods have led people in the most developing countries to shift their consumption to cowpeas and other grain legumes. Due to its tolerance for sandy soil and low rainfall, it is an important crop in the semiarid regions across Africa and Asia. Of the different species of bean consume in the country, cowpeas in particular have attracted attention as possible home grown sources of protein and successive selections have made it possible to introduce several high yielding varieties with desirable packages of nutrients and with resistance to pest and microbial infections (Ologhobo et al, 1983). 1.1 Background of the Study 1 1.2 Problem Statement 6 1.3 Objectives of the Study 10 1.4 Justification of the Study 10 1.5 Organisation of the Study 14 CHAPTER TWO: LITERATURE REVIEW 15 2.1 Introduction 15 2.2 Cowpea Production 15 2.2.1 Economic importance of cowpea production 15 2.2.2 Determinants of cowpea production 18 [21], The size and shape of the leaves vary greatly, making this an important feature for classifying and distinguishing cowpea varieties. Genetically modified cowpeas are being developed to express the cry protein from Bacillus thuringiensis, which is toxic to lepidopteran species including the maruca. Using an adapted cowpea variety that is more compatible with warm season grasses may help to overcome this issue. [36] Temperatures of 60 °C (140 °F) kill the weevil larvae, leading to a recent push to develop cheap forms of solar heating that can be used to treat stored grain. [13][25], Cowpeas thrive in poor dry conditions, growing well in soils up to 85% sand. (IPM CRSP, 2000). [18] Cowpeas can either be short and bushy (as short as 20 cm or 8 in) or act like a vine by climbing supports or trailing along the ground (to a height of 2 m or 6 ft 7 in). Finally, to all members of “The Prayer Stronghold International Ministries” family friends ... General background and History 5 2.1.3. The plants are thought to be native to West Africa and are widely cultivated in warm regions around the world. [6] Sesquipedalis in Latin means "foot and a half long", and this subspecies which arrived in the United States via Asia is characterised by unusually long pods, leading to the common names of yardlong bean, asparagus bean, and Chinese long-bean. Background. Most cowpeas are grown on the African continent, particularly in Nigeria and Niger, which account for 66% of world production. Use of ex vitro composite plants to study the interaction of cowpea (Vigna unguiculata L.) with the root parasitic angiosperm Striga gesnerioides. [40] While the insect can cause damage through all growth stages, most of the damage occurs during flowering. COMPARATIVE STUDY OF THE GROWTH PERFORMANCE OF FOUR COMMERCIAL FISH FEEDS IN THE PRODUCTION OF AFRICAN CATFISH (CLARIAS GARIEPINUS). Leaves can be picked from 4 weeks after planting. Increase in vegetable protein, vitamin and soluble carbohydrates supply from cowpea in malnourished areas presents a less difficult, less expensive and more energy efficient solution. It improves soil fertility because of its ability to fix nitrogen efficiently (up to 240 kg N per hectare) and can leave a fixed- N deposit in the soil of up to 60 – 70 kg/ha for the succecding crop (Rechie, 1985; Kachare, et al.1988). 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. Background Cowpea (Vigna unguiculata) is the most important grain legume and fodder crop in the dry savannas of tropical Africa. [53] Drought lowers the growth rate and development, ultimately reducing yield, although cowpea is considered more drought tolerant than most other crops. 1.1 Background of the Study Cowpea (Vigna unguiculata (L).Walp) is a tropical grain legume widely grown in sub-Saharan Africa (SSA), Asia, parts of the United States and Southern Europe (Singh et al., The cowpea (Vigna unguiculata) is an annual herbaceous legume from the genus Vigna. [27] In 2300 BC, the cowpea is believed to have made its way into Southeast Asia, where secondary domestication events may have occurred. [48] Common diseases include blights, root rot, wilt, powdery mildew, root knot, rust and leaf spot. [46] The most common methods of protection involve the use of insecticides, the main pesticides used being carbamates, synthetic pyrethoids, and organophosphates. 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. It is grown on more than 12.5 million hectares of largely smallholder farms, with an estimated production of more than 3 million metric tonnes. Some abiotic and biotic stresses adversely affect its productivity. 1976). In addition, they supply the essential minerals, calcium, magnesium, potassium, iron, zinc and phosphorus (Aykroyed et al. as a food crop in tropical and subtropical regions, especially in West Africa (Rachie, 1973; R.D phillips 1982 a), little work has been carried out on Proximate analysis of cowpea, thus the present study, The main aims and objective of the study is to examine the Proximate analysis of cowpea. The crop is mainly grown for its seeds, which are high in protein, although the leaves and immature seed pods can also be consumed. As well as an important source of food for humans in poor, arid regions, the crop can also be used as feed for livestock. The objectives of this study were to analyse the cowpea transcriptome and develop genic molecular markers for future genetic studies of this genus. BACKGROUND. Cowpea [Vigna unguiculata (L.) Walp.] [11] All cultivated cowpeas are found within the universally accepted V. unguiculata subspecies unguiculata classification, which is then commonly divided into four cultivar groups: unguiculata, biflora, sesquipedalis, and textilis. [54] Drought at the preflowering stage in cowpea can reduce the yield potential by 360 kg/ha. As the cowpea plant develops, leaves are picked Due to its tolerance for sandy soil and low rainfall, it is an important crop in the semiarid regions across Africa and Asia. [24] Although there is no archaeological evidence for early cowpea cultivation, the centre of diversity of the cultivated cowpea is West Africa, leading an early consensus that this is the likely centre of origin and place of early domestication. RESULTS [57], Cowpeas are grown mostly for their edible beans, although the leaves, green seeds and pods can also be consumed, meaning the cowpea can be used as a food source before the dried peas are harvested. The objectives of the study were to determine the extent of genetic diversity present among a collection of cowpea accessions from Zambia and Malawi using phenotypic traits and single nucleotide … Close, Alisa Huffaker, and Eric A. Schmelz: This page was last edited on 18 January 2021, at 16:03. 1.1 Background Cowpea is a widely grown legume in tropical and subtropical Africa. [45] An individual bruchid can lay 20–40 eggs, and in optimal conditions, each egg can develop into a reproductively active adult in 3 weeks. [5] The legume pod borer, Maruca vitrata, is the main preharvest pest of the cowpea. Genetic improvement of the crop is being actively … The effect of anti-nutritional factors (tannin, phytic acid , and tryps in inhibitors) on cowpea protein, The proximate and mineral composition of cowpea grains. [74], This appears to be one of the latest taxonomical classifications, International Institute of Tropical Agriculture, Food and Agriculture Organization of the United Nations, "The Plant List: A Working List of All Plant Species", "International Plant Names Index, entry for, "International Plant Names Index, entry for Pl. It is a member of the leaf beetle family, Chrysomelidae, and not a true weevil.This common pest of stored legumes has a cosmopolitan distribution, occurring on every continent except Antarctica. However, post-harvest losses associated with this crop still remain a critical issue of concern in most developing countries. Productivity of cowpea [Vigna unguiculata (L.) Walp] in sub-Sahara Africa is curtailed by a lack of farmer-preferred and improved cultivars and modern production technologies. Cowpea is a legume that is extensively grown throughout sub-Saharan Africa. Background: Beans from cowpea cultivars fertilized with mineral N or inoculated with various rhizobium strains may contain different nitrogen concentrations and nitrogen metabolite composition, which affects the beans' defense mechanisms against pests. [62], Most cowpeas are grown on the African continent, particularly in Nigeria and Niger, which account for 66% of world cowpea production. [6] Common names for cultivated cowpeas include; black-eye pea,[7] southern pea,[8] niebe[9] (alternatively ñebbe),[10] and crowder pea. 1.1 Background of the study. Cowpea are major sources of protein in developing countries where consumption of certain animal foods is taboo because of religious or customary beliefs. It is mostly cultivated by small-scale (subsistence) farmers, usually intercropped with maize or sorghum. The whole plant is used as … [30] Its nitrogen-fixing ability means that as well as functioning as a sole crop, the cowpea can be effectively intercropped with sorghum, millet, maize, cassava, or cotton. 1982). [41], Severe C. maculatus infestations can affect 100% of the stored peas and cause up to 60% loss within a few months. Millions of african farmers grow cowpea, some two hundred million africans consume Black-eyed peas were first introduced to the southern states in the United States and some early varieties had peas squashed closely together in their pods, leading to the other common names of southern pea and crowder pea. cowpea crop species on the farmers’ land, distribution status, finding the suitable solution for the major production areas in the study area, what are the constraints of cowpea productions in the study area and so on? [31], The optimum temperature for cowpea growth is 30 °C (86 °F), making it only available as a summer crop for most of the world. Rar.

Cowpea is economically useful as vegetable (leaves), a protein source (seeds and young pods), fodder and pulse crop. [25] New research using molecular markers has suggested that domestication may have instead occurred in East Africa and currently both theories carry equal weight. Use of ex vitro composite plants to study the interaction of cowpea (Vigna unguiculata L.) with the root parasitic angiosperm Striga gesnerioides Karolina E Mellor, Ava M Hoffman and Michael P Timko* Abstract Background: Cowpea (Vigna unguiculata L.) is an … The seeds are usually cooked and made into stews and curries, or ground into flour or paste. [19][21] Their texture and colour are very diverse. Background: Cowpea is a highly inbred crop. 1961) as well as North and South America and Asia. Cowpea is a drought-resistant crop, a characteristic that makes it ideal for growth in East and West Africa. Cowpea is grown mainly for the seed and sometimes pods in West Africa, India and South America, but it is grown for both seeds, pods and leaves in East Africa. Warm season mixes may also simply outcompete cowpea, specifically warm season grasses such as millet and sorghum-sudangrass. unguiculata var. Like other grain legumes, cowpeas are a good source of energy, proteins (amino acids), vitamins, minerals and deitary fiber. Background: Plant-growth-promoting rhizobacteria (PGPR) and arbuscular mycorrhizal (AM) fungi have the ability to enhance the growth, fitness, and quality of various agricultural crops, including cowpea. [19][20] The taproot can penetrate to a depth of 2.4 m (7 ft 10 in) after eight weeks. 1995; Bravo et al., 1994; Bhattacharya et al. [50] One of the plant's defenses against some insect attacks is the cowpea trypsin inhibitor (CpTI). 1993). The commonly used washing treatments in household processing were used for comparison. [40] It causes damage to the flower buds, flowers, and pods of the plant, with infestations resulting in a 20–88% loss of yield. [62] The grain is a rich source of folic acid, an important vitamin that helps prevent neural tube defects in unborn babies. Dietary Supplement: Cowpea fortified with NaFeEDTA, in form of Toubani. [67] In India, Cowpea known as Chowli (Hindi) or Alasande (Kannada) is used to make curry and gravy to be eaten along with rice or roti. Niger is the main exporter of cowpeas and Nigeria the main importer. Cowpea seeds acts as a major source of protein (22-24%), vitamins and minerals (Coetzee 1995). [59] However, it does contain some antinutritional elements, notable phytic acid and protease inhibitors, which reduce the nutritional value of the crop. [39] Other important pests include pod sucking bugs, thrips, and the postharvest cowpea weevil, Callosobruchus maculatus. Cowpeas were domesticated in Africa[citation needed] and are one of the oldest crops to be farmed. [69] Cowpea starch is digested more slowly than the starch from cereals, which is more beneficial to human health. [4] While they play a key role in subsistence farming and livestock fodder, the cowpea is also seen as a major cash crop by Central and West African farmers, with an estimated 200 million people consuming cowpea on a daily basis. [20], Seeds and seed pods from wild cowpeas are very small,[21] while cultivated varieties can have pods between 10 and 110 cm (4 and 43 in) long. [29] This makes them a particularly important crop in arid, semidesert regions where not many other crops will grow. [23] A pod can contain six to 13 seeds that are usually kidney-shaped, although the seeds become more spherical the more restricted they are within the pod. In a study of 100 cowpea. [42][43] The weevil generally enters the cowpea pod through holes before harvest and lays eggs on the dry seed. [38], Insects are a major factor in the low yields of African cowpea crops, and they affect each tissue component and developmental stage of the plant. Despite the importance of cowpea (Vigna unguculata L. [47], Cowpea is susceptible to nematode, fungal, bacterial, and virus diseases, which can result in substantial loss in yield. Comparing the effectivity of Glutinous rice starch (Oryza Sativa var Glutinosa) and Cassava starch (Manihot Esculenta) in making Biodegradable plastic CHAPTER 1 BACKGROUND OF THE STUDY Plastics are a part of our daily lives. [51] CpTI is the only gene obtained outside of B. thuringiensis that has been inserted into a commercially available genetically modified crop. The whole plant is used as forage for animals, with its use as cattle feed likely responsible for its name. Despite its importance, researchers have fewer ways to study cowpea plants, which means that researchers had to turn to the tobacco plant to test how these receptors actually work. PubMed Central. 2012-01-01. Sosulski, 1987; Fashakin, 1986; Philips, 1987; Saeed, 1977; El Hardallou, 1980). BACKGROUND OF THE STUDY. [12][15], The first written reference of the word 'cowpea' appeared in 1798 in the United States. [70], The cowpea has often been referred to as "poor man's meat" due to the high levels of protein found in the seeds and leaves. Background. Cowpeas (Vigna unguiculata and Vigna Senensis) are important grain legumes in East and West Africa as well other developing countries (Dovlo et al. Chloe Bustillo. [32], These characteristics, along with its low fertilisation requirements, make the cowpea an ideal crop for resource-poor farmers living in the Sahel region of West Africa. [44] The larvae burrow their way into the seed, feeding on the endosperm. In addition to their use as a protein-rich food crop, cowpeas are extensively grown (Hasskarl)", "Southern Peas - Gardening Solutions - University of Florida, Institute of Food and Agricultural Sciences", "Niebe: A Food of Choice to Combat Hunger", "Genetic Diversity and Population Structure of Cowpea (, "The Potential Role of Neglected and Underutilised Crop Species as Future Crops under Water Scarce Conditions in Sub-Saharan Africa", "Toxicity and repellence of African plants traditionally used for the protection of stored cowpea against Callosobruchus maculatus". [5] The legume pod borer Maruca vitrata is the main preharvest pest of the cowpea and the cowpea weevil Callosobruchus maculatus the main postharvest pest. The weevil develops into a sexually mature adult within the seed. In bad infestations, insect pressure is responsible for over 90% loss in yield. Cowpeas can be erect, semierect (trailing), or climbing. [17], A large morphological diversity is found within the crop, and the growth conditions and grower preferences for each variety vary from region to region. Background. Review of Politics and Public Policy in Emerging Economies Vol. Study subjects will receive 3 times per week, as part of the school feeding programme 66g of raw fortified cowpea (with added 10mg Fe as NaFeEDTA)in form of Toubani (a cowpea based snack). Cowpea, (Vigna unguiculata), annual plant within the pea family (Fabaceae) grown for its edible legumes. spontanea) populations from West Africa, using It is a subsistence crop, often intercropped with sorghum, maize and pearl millet. It is also utilized as fodder and as quick growing cover-crop. [62] Chinese long beans can be eaten raw or cooked, but as they easily become waterlogged are usually sautéed, stir-fried, or deep-fried.[63]. [68] A seed can consist of 25% protein and has very low fat content. Background:Nutritional anemia is a public health problem among Ghanaian schoolchildren. This study examined outcrossing rates and genetic structures in 35 wild cowpea (Vigna unguiculata ssp. In Sudan, people relied mostly on other available leguminous crops (Ahmed and Nour, 1990). [49] The cowpea mosaic virus (CPMV), discovered in 1959, has become a useful research tool. It grows best in regions with an annual rainfall between 400 and 700 mm (16 and 28 in). Callosobruchus maculatus is a species of beetles known commonly as the cowpea weevil or cowpea seed beetle. Legumes are sometimes refserred to as “poor man’s meat” or the “rich man’s vegetable” ( Walker, 1981). [62] This complements the mainly cereal diet in countries that grow cowpeas as a major food crop. It is against this background that the study intends to analyzed the level of the effects of insurgency on cowpea farmers in the study area. The specific objectives of this study were to assess: Legumes are primarily important as sources of protein in diets in many parts of the world. Consequently, cowpea production should be enhanced. [62] Although little research has been conducted on the nutritional value of the leaves and immature pods, what is available suggests that the leaves have a similar nutritional value to black nightshade and sweet potato leaves, while the green pods have less antinutritional factors than the dried seeds. 30, A receptor-like protein mediates plant immune responses to herbivore-associated molecular patterns, Saliva From Hungry Caterpillars Alerts Cowpea Plants to Turn on Their Defenses, https://en.wikipedia.org/w/index.php?title=Cowpea&oldid=1001180911, Taxonbars with automatically added basionyms, Creative Commons Attribution-ShareAlike License, crowder-pea, southern pea, black-eyed pea, niebe, ñebbe, yardlong bean, asparagus bean, Chinese long-bean. Hence, this research was initiated with the [72], According to the Food and Agriculture Organization of the United Nations, as of 2012, the average cowpea yield in Western Africa was an estimated 483 kilograms per hectare (0.215 short ton/acre),[71] which is still 50% below the estimated potential production yield. Cowpeas are a major source of thiamin and niacin and also contain reasonable amount of other water- soluble vitamins, riboflavin, pyridoxine and folacin. [56] International Institute of Tropical Agriculture (IITA), Nigeria and Institut de I’Environment ae de Recherches Agricoles are working on cowpea crop wild relatives to tap the genetic diversity and transfer that into cultivars to make them more tolerant to different stresses and adaptive to climate change. The beans are also known by other names such as blackeye beans, southern peas, … Cowpea is most widely consumed legume in Nigeria as it represents a cheap source of dietary protein. They are grown mainly for their edible beans. Cowpea grains contain around 22% protein and provide a cheap source of dietary protein for low-income urban and rural populations. They can have a smooth or rough coat and be speckled, mottled, or blotchy. Background: Productivity of cowpea [Vigna unguiculata (L.) Walp] in sub-Sahara Africa is curtailed by a lack of farmer-preferred and improved cultivars and modern production technologies. is one of the most important legumes in tropical and semi-arid regions.However, there is relatively little genomic information available for genetic research on and breeding of cowpea. Intense efforts to find alternative sources of proteins from plants adapted to adverse conditions are being conducted around the world (Siddhuraju et al. [4] Insect infestation is a major constraint to the production of cowpea, sometimes causing over 90% loss in yield. Similarly, pr otein content of. The pulse is indigenous to Africa (Okigbo, 1986), though it is now grown in other continents, such as Central America (Bressani et al. [12][13] The classification of the wild relatives within V. unguiculata is more complicated, with over 20 different names having been used and between 3 and 10 subgroups described. Adam D. Steinbrenner, Maria Muñoz-Amatriaín, Antonio F. Chaparro, Jessica Montserrat Aguilar-Venegas, Sassoum Lo, Satohiro Okuda, Gaetan Glauser, Julien Dongiovanni, Da Shi, Marlo Hall, Daniel Crubaugh, Nicholas Holton, Cyril Zipfel, Ruben Abagyan, Ted C. J. Turlings, Timothy J. Materials and Methods [12] However, as the plant is primarily self-pollinating, its genetic diversity within varieties is relatively low. [73] In some tradition cropping methods, the yield can be as low as 100 kilograms per hectare (0.045 short ton/acre). Cowpea proteins provide the three esential amino acids lysine threonine and methionine, (Dhankher et al 1990. [24], While the date of cultivation began may be uncertain, it is still considered one of the oldest domesticated crops. [52], Besides biotic stresses, cowpea also faces various challenges in different parts of the world such as drought, heat, and cold. Cowpea, Vigna unguiculata (L.), is an important grain legume grown in the tropics where it constitutes a valuable source of protein in the diets of millions of people. [49] The plant is susceptible to mosaic viruses, which cause a green mosaic pattern to appear in the leaves. [58] Like other legumes, cowpeas are cooked to make them edible, usually by boiling. This trend has been observed in parts of northern Nigeria where pork and pork products, horse meat, donkey meat and meat of camels and asses are avoided by muslims. 1, No 1, June 2019 55 The grain provides valuable protein and the leaves are used as a nutritious vegetable. One peduncle can support four or more seed pods. Jav. Traditional methods of protecting stored grain include using the insecticidal properties of Neem extracts, mixing the grain with ash or sand, using vegetable oils, combining ash and oil into a soap solution or treating the cowpea pods with smoke or heat. [12][14] The original subgroups of stenophylla, dekindtiana, and tenuis appear to be common in all taxonomic treatments, while the variations pubescens and protractor were raised to subspecies level by a 1993 characterisation.
