[63] The virus is spread by the whitefly and by the transplanting of diseased plants into new fields. [27], Cassava, yams (Dioscorea spp. Cooked cassava is called kappa or maricheeni in Malayalam. They vary in crop duration (6 to 11 months) and yield (25 to 40 t/ha) depending soil, location and its final use. [64], Cassava brown streak virus disease has been identified as a major threat to cultivation worldwide. Worldwide, 800 million people depend on cassava as their primary food staple. MUMBAIPhone : +91 22 66778899Email: Info@cassavaindia.com, Copyright © 2020 Cassava Development Authority. above 10% of the relevant DV). Cassava is one of the most drought-tolerant crops, can be successfully grown on marginal soils, and gives reasonable yields where many other crops do not grow well. ), and sweet potatoes (Ipomoea batatas) are important sources of food in the tropics. Cooked cassava starch has a digestibility of over 75%.[32]. Cassava is a highly productive crop when considering food calories produced per unit land area per day (250,000 cal/hectare/day, as compared with 156,000 for rice, 110,000 for wheat and 200,000 for maize). In India, Cassava is cultivated in an area of 2.28 lakhs hectares with a total production of 4.6 million tonnes and little has changed over the past 25 years compared to global production that has almost doubled during the same period. While it is a valued food staple in parts of eastern Indonesia, it is primarily cultivated for starch extraction and bio-fuel production in Thailand, Cambodia or Vietnam. Alcoholic beverages made from cassava include cauim and tiquira[what language is this?] [60] In Africa, a previous issue was the cassava mealybug (Phenacoccus manihoti) and cassava green mite (Mononychellus tanajoa). [67], The use of nematicides has been found to result in lower numbers of galls per feeder root compared to a control, coupled with a lower number of rots in the storage roots. Its also the key ingredient for a diverse range of other products including sweeteners, alcohol, confectionery, paper, adhesives/binder, textiles, animal feeds, chemicals, industrial, pharmaceutical. Further highlighting India’s capacity to increase production. This is equivalent to the replacement of 10 million tonnes of petroleum. This mutated virus spread at a rate of 80 kilometres (50 miles) per year, and as of 2005 was found throughout Uganda, Rwanda, Burundi, the Democratic Republic of the Congo and the Republic of the Congo. It is therefore possible that extensive galling can be observed even at low densities following infection. Though it is often called yuca in Spanish America and in the United States, it is not related to yucca, a shrub in the family Asparagaceae. In some countries of sub-Saharan Africa, cassava is even a staple or a sub-staple. feeding produces physically damaging galls with eggs inside them. [72] The organophosphorus nematicide femaniphos, when used, did not affect crop growth and yield parameter variables measured at harvest. "[44][45], During the shortages in Venezuela in the late 2010s, dozens of deaths were reported due to Venezuelans resorting to eating bitter cassava in order to curb starvation. [50] The reliance on cassava as a food source and the resulting exposure to the goitrogenic effects of thiocyanate has been responsible for the endemic goiters seen in the Akoko area of southwestern Nigeria. Around the same period, it was also introduced to Asia through Columbian Exchange by Portuguese and Spanish traders, planted in their colonies in Goa, Malacca, Eastern Indonesia, Timor and the Philippines. Cassava can be cooked in many ways. [65] Meloidogyne spp. [22] Cassava is sometimes described as the "bread of the tropics"[23] but should not be confused with the tropical and equatorial bread tree (Encephalartos), the breadfruit (Artocarpus altilis) or the African breadfruit (Treculia africana). In the humid and sub-humid areas of tropical Africa, it is either a primary staple food or a secondary costaple. [67], "Yuca" redirects here. A comparative table shows that cassava is a good energy source. [17] The cultivation and consumption of cassava was nonetheless continued in both Portuguese and Spanish America. Comparisons between the nutrient content of cassava and other major staple foods when raw must be interpreted with caution because most staples are not edible in such forms and many are indigestible, even dangerously poisonous or otherwise harmful. Cassava shelf life may be increased up to three weeks by overexpressing a cyanide insensitive alternative oxidase, which suppressed ROS by 10-fold. The large roots are peeled and then ground into flour, which is then soaked in water, squeezed dry several times, and toasted. Ideal for India and the subcontinent’s climates that can suffer extreme dry conditions and adverse conditions. In many countries, significant research has begun to evaluate the use of cassava as an ethanol biofuel feedstock. It is used in cholent in some households. Cassava hay is harvested at a young growth stage (three to four months) when it reaches about 30 to 45 cm (12 to 18 in) above ground; it is then sun-dried for one to two days until its final dry matter content approaches 85 percent. [6] It has also been linked to tropical calcific pancreatitis in humans, leading to chronic pancreatitis. [56] PPD is one of the main obstacles preventing farmers from exporting cassavas abroad and generating income. [49], The traditional method used in West Africa is to peel the roots and put them into water for three days to ferment. On 22 December 2007, the largest cassava ethanol fuel production facility was completed in Beihai, with annual output of 200 thousand tons, which would need an average of 1.5 million tons of cassava. Over 60 percent of cassava production in China is concentrated in a single province, Guangxi, averaging over seven million tonnes annually. They have not been shown to cause direct damage to the enlarged storage roots, but plants can have reduced height if there was loss of enlarged root weight. [38] Cassava varieties are often categorized as either sweet or bitter, signifying the absence or presence of toxic levels of cyanogenic glucosides, respectively. [41] Excess cyanide residue from improper preparation is known to cause acute cyanide intoxication, and goiters, and has been linked to ataxia (a neurological disorder affecting the ability to walk, also known as konzo). This crop has … In the subtropical region of southern China, cassava is the fifth-largest crop in term of production, after rice, sweet potato, sugar cane, and maize. [48] The flour is used throughout South America and the Caribbean. Cassava thus serves as both a cash and a subsistence crop. By 4,600 BC, manioc (cassava) pollen appears in the Gulf of Mexico lowlands, at the San Andrés archaeological site. [51][52], A project called "BioCassava Plus" uses bioengineering to grow cassava with lower cyanogenic glycosides combined with fortification of vitamin A, iron and protein to improve the nutrition of people in sub-Saharan Africa. Cassava (Manihot esculenta crantz) also known commonly as Tapioca, continues to be a crop of food security for the millions of people especially in the developing countries of the globe. It is an important alternate source of energy to meet the demands of increasing population. (Darjeeling, Sikkim, India). [53][54], Cassava is harvested by hand by raising the lower part of the stem, pulling the roots out of the ground, and removing them from the base of the plant. Nigeria produced 59 million tonnes making it the world’s largest producer with Thailand 2nd at 31.5 million tonnes. Maize and cassava are now important staple foods, replacing native African crops in places such as Tanzania. Currently it is largely cultivated in Tamil Nadu, Kerala, parts of Nagaland, Meghalaya, Andhra Pradesh and Assam. [citation needed] It can be made into a flour that is used in breads, cakes and cookies. [21] Cassava has also become an important crop in Asia. A flavorless, colorless, odorless starch extracted from the root of the plant species Manihot esculenta. Other major growers were Thailand and Democratic Republic of the Congo.[26]. Compared to most staples; however, cassava is a poorer dietary source of protein and most other essential nutrients. These pests can cause up to 80 percent crop loss, which is extremely detrimental to the production of subsistence farmers. In Nigeria and several other west African countries, including Ghana, Cameroon, Benin, Togo, Ivory Coast, and Burkina Faso, they are usually grated and lightly fried in palm oil to preserve them. Although a perennial plant, cassava is extensively cultivated as an annual crop in tropical and subtropical regions for its edible starchy tuberous root, a major source of carbohydrates. Of particular concern are the cyanogenic glucosides of cassava (linamarin and lotaustralin). The flesh can be chalk-white or yellowish. The Brazilian farinha, and the related garri of West Africa, is an edible coarse flour obtained by grating cassava roots, pressing moisture off the obtained grated pulp, and finally drying it (and roasting in the case of farinha). Cassava, like other foods, also has antinutritional and toxic factors. A starchy food made from the cassava plant used in puddings. [7][6] Farmers often prefer the bitter varieties because they deter pests, animals, and thieves.
