	Food-Info.net : Tropical roots and tubers : Cocoyam
		Cocoyams are found as an important crop only in warm, humid forest areas because of their need for high annual rainfall and a long wet season.
		Cocoyam flour has the added advantage that it is highly digestible and so is used for invalids and as an ingredient in baby foods.
		Taro (a variant of cocoyam) is the traditional staple in the Pacific Islands, where it is made into a series of food products similar to those described for cassava.

	Evaluation of Macabo Cocoyam Germplasm in Cameroon
		Much of this cocoyam population in Cameroon and the rest of the West African Region, are land races of previous introductions especially by the Portuguese.
		Cocoyam farmers carried out several cultural practices such as multiple cropping, hill planting, early planting, and early harvesting in order to reduce the disease incidence and its devastating effects on yield.

	Variability and germplasm loss in the Cameroon national collection of cocoyam (Xanthosoma sagittifolium (L.) Schott)
		The collected germplasm was evaluated in Cameroon during the 1989, 1990, 1991 and 1992 cocoyam growing seasons.
		The highest variability, as indicated by the coefficient of variation, was recorded in Type II population for cormel yield per plant, indicating that this population is the most heterogeneous for this parameter.
		The Type III plants exhibited the lowest variability for number of leaves per plant while the three cocoyam types were distinct for plant height and single cormel weight.

	The potential of peels of mango, plantain, cocoyam and pawpaw as diets for growing snails (Archachatina marginata)
		The peels of the different fruits had similar composition but were considerable lower in DM, crude protein and ash content compared with the pawpaw leaves.
		There are recent research findings on the use of pawpaw leaf and fruit, cocoyam tubers and mango fruits for feeding snails (Imevbore 1990; Awah 1992) but there is a paucity of information on the use of the peel of these crops in the diet of snails.
		Hence this study was conducted to investigate growth and carcass analysis of snails fed peels of plantain, cocoyam, mango and pawpaw.

		Ornamental cocoyam and wild sweet yam were harvested from the farm in the month of November at Iko Town in Eastern Obolo and Nung Ukot Itam in Itu areas respectively in Akwa Ibom State, Nigeria.
		Extraction of the starch from the ornamental cocoyam and wild sweet yam were carried out by filtering grated mixtures of each with a cheese cloth to obtain a filtrate free of fibres.
		1 it is observed that wild cocoyam starch increases the ultimate tensile strength of the composite between 0-10 wt % starch composition.

		The usable parts in both species are the subterranean tuberous stems which, in the case of the latter, contain between 15 and 39 percent of carbohydrates, 2 to 3 percent of protein and 70 to 77 percent of water; both have a nutritional value comparable to the potato and are probably easier to digest.
		In one related species, the cocoyam, with a possibly wider variation, all the clones are considered as a single species.
		Cytological studies of a world collection may lead, as in the case of the cocoyam, to the establishment of natural groups of cultivars and may also serve as a basis for genetic improvement.

		Cocoyam is a short swollen underground corm (similar to a tuber) called colocasia esculanta.
		Cocoyam is very rich in dietary fibre, thus will help in preventing abdominal disorders like diverticulitis, constipation and poor bowel motility.
		Cocoyam fu fu is traditionally made from cocoyam by boiling the cocoyam after peeling off the covering, place it in a mortar and beat it smooth with a pestle and roll it into balls ready to be served with a delicious African food soup.

		The tubers were white yam, cassava, yellow yam, white cocoyam, red cocoyam, and water yam.
		The least preferred tubers were yellow yam, white cocoyam, red cocoyam, and water yam.
		Cocoyam, yellow yam, and water yam have higher digestible true protein than white yam and cassava (table 2); they are also richer in water-soluble vitamins and carotene [11-14].

	Taro Production Guidelines for Kauai
		In fact cocoyam, which is a close relative of taro, and consumed by the Latin and Caribbean population, was about the only vegetable that survived the devastating freeze that hit South Florida on the early morning of December 26, 1989.
		The undamaged cocoyam corms (the underground storage organ, which is actually stem tissue is called a corm) lying below the soil level, however, re-sprouted once the temperatures rose and plants which were ready for harvest were dug a few months later.
		Similarly in the Pacific Islands, taro, and other relatives of the aroid family are often the first crops grown in islands and atolls which have been hit by hurricanes or flooding tidal waves.

	Root Crops - Phase III
		Significant progress has been made in developing a strong, indigenous, institutional base for research on cassava, cocoyams, yams, and sweet potatoes, particularly by training a number of Cameroonian scientists.
		Phase III will continue to develop improved varieties of cassava, yam, cocoyam, and sweet potato, incorporating field resistance to major diseases and pests into improved varieties of the four crops; and develop improved cropping practices for these root crops, which will be readily accepted by farmers.
		This project improved varieties of cassava, yam, cocoyam, and sweet potatoes by increasing field resistance to major diseases and pests.
