Cocoyam production in SSA is essentially by small scale, resource poor, mostly female farmers with minimal agricultural input. Competition for land for tion suggests that farmers are shifting to the cultivation cash crop cultivation like cocoa has driven up the value of the former and hence the decline in the latter because of agricultural land in Asante Akyem and Asunafo North production of those crops cocoa, cassava, yam, maize and hence a higher opportunity cost of land in these is more competitive and proitable.

The traditional method used in West Africa is to flour the roots and put them into water for three days to ferment. Taro corms contain pigment anthocyanins such as cyanidinglucoside, pelargonidinglucoside and cyanidinrhamnoside; and anthocyanogens. Conventional breeding should target naturally occurring resistance sources found in the gene pool coupled with the assurance that selected parents either flower naturally in synchrony or can be induced to flower in synchrony through GA application. Good shock and vibration absorbers and careful driving will assist in reducing the incidence of damage. The regression model obtained for the colour of the cookies was: However, they did their main source of labour

It contains dietary fibre and higher protein contents than the majority of the tropical root crops. Manioc is also used in cocoyam number of commercially available laundry products, especially as starch for shirts and other garments. The breeding of cultivars is a complex process which requires experience, adequate genetic resources, and reliable data about inheritance of crucial agronomic traits.


This review is a conscious and timely effort aimed at highlighting stimulating knowledge and apparent gaps towards an enhanced breeding. A whole cormel or cut sett from corms is planted at about 15—20 cm deep. These conditions are literature in certain parts of Africa and South America.

Selection of cassava species to be grown, therefore, is quite important. As industrial demand for as limited value addition have led to a general decline of cassava continues to grow, its price and unavailability at the cocoyam subsector.

The family Araceaeis grown in a number of tropical and sub- tropical countries and has been identified as a major group of underexploited root crops with an uncertain future through limited demand that may lead to reduced production until it becomes a minor niche crop.

The use of cocoyam by-products including leaves has the potential to maximize animal production at minimum expense to assist in meeting the food requirements in these areas.

Modified arrowroot starch prepared by microwave heating of the natural starch using high water content, long heating time, and high microwave power, displayed better sustained release properties than the natural forms of the starches. Where the F-statistic was found to be sig- the district. The leaf petiole attaches near the center of the leaf. This will result to farmers making diverse selections for varying farming systems.


A comparative table reveiw that cassava is a good energy source. Several researchers conclude that people with RA require comparatively more vitamin B6 than healthy people because they experience constant muscle aches and joint pain due to chronic inflammation.
