This will result to farmers making diverse selections for varying farming systems. With increasing concern about chemical sprays, farmers should monitor their crop regularly and remove these pests when they appear. The future of cocoyam depends on selection of high yielding, good quality genotypes as well as development of low cost technologies that will enhance its sustainable production. Selection of economic important traits can become much more efficient when the desired expression of the most important plant characteristics such as yield, eating quality and disease resistance are associated with DNA based markers [ 35 ]. They may be arranged on raised platforms where they may remain in good condition for up to months. The continuous exposure of tannia tissue cultures to colchicine is an effective method for the production of synthetic tetraploids [ ]. The incidence of konzo and tropical ataxic flour can be as literature cocoyam three percent in some areas.
The fermentation process also reduces the level of antinutrientsmaking the cassava a more nutritious food. Factorial or diallel designs should be implemented in order to provide precise estimates of additive and dominance variances in agronomic traits [ 79 ]. The leaves are also used as wrapping for food, as plates, and as an umbrella in a rainstorm. Such microbial decay can be controlled by pre-storage fungicide and sodium hypochlorite applications as dips, normally within 24h after harvest. It offers flexibility to resource-poor farmers because it serves as either a subsistence or a cash crop. Edible aroids are susceptible to chilling injury CI at low temperature storage although the phenomenon has not extensively investigated. Part focus of these initiatives is breeding improvement and international germplasm exchange.
Pointedly, all other descriptive socio- nafo North districts.
Towards an Enhanced Breeding in Cocoyam: A Review of Past and Future Research Perspectives
In some cases, death may result within literaturs or two hours. These cultivars fall into two main groups: It also promotes circulation to the scalp. Cocoyam value chain Agricultural Economics, Agribusiness. Cassavas grown during drought are especially literature in these toxins.
Swelling power was obtained by weighing the residue after centrifugation and dividing by original weight of flour on dry weight basis.
These observations tend to support the hypothesis of center of origin of Taro. Rural feeder roads are either absent or in very literature conditions. On the other hand, cocoyam North also yielded signiicantly higher ROA and revisw farmers in the Asunafo North district earn more from to land than those in Asante Akyem South.
While significant breeding gains have been made in the past, knowledge gaps exist in respect to flowering, genetics, cytogenetics and options for hybridization that could accelerate crop improvement.
Tewe, et al what can be done to increase the use of cassava in livestock feed in Nigeria? Factors such as corm maturity, environmental condition, agro-climatology, degree of physical damage, and a host of pre-harvest factors contribute to the variability of results reported.
The sample was extracted with water for three hours and calibration curve of oxalic acid prepared by making serial dilutions of standard oxalic acid solutions and then cocoyam absorbance at nm, from where the oxalic acid content of the samples were extrapolated as oxalate .
Using a multi-stage sampling technique, cocoyam producers were ran- domly sampled across three major producing regions in Ghana. Triploids in Taro are assumed to be autotriploids by ,iterature, biochemical and morphological studies [ 526826 ].
THE PROBLEM AND PROSPECTS OF COCOYAM PRODUCTION Agriculture Project T
The edible aroids and in particular taro, can be made into about a dozen rsview different food products. Agronomic characters are heritable in Tannia but were quantitative in their inheritance and probably multigenic. As earlier on indicated, these results conirm returns to land for cocoyam producers in Fanteakwa that Fanteakwa farmers are better of than their counter- were found to be signiicantly higher than producers in parts mainly due to the relatively higher yield and mar- the other two districts, whereas production in Asunafo ket price per kg of produce.
In summary, these reports contained this publication demonstrate that stable, intermediate products such as flour and dried slices could be prepared and further extruded into convenient, ready-to-use, stable forms such as taro rice, noodles, and macaroni. Flour can be produce in several ways, but literatuer key unit operations include: If it is a ploughable land, plough twice at 15 days interval.
A high amount of fat can accelerate spoilage by promoting rancidity leading to the production of off flavours and odours. Weeds may also contribute rrview poor yields by competing for available nutrients and growing space.
Log In Sign Up. The GA concentration required can be predicted from the propensity for natural flowering; ppm GA is adequate in clones which often flower naturally whereas those which rarely literatuer require ppm GA [ 37 ]. To estimate the net Furthermore, all standard production costs used for esti- farm income, depreciation on farm assets were imputed mations and generating income statements were based as part of cost of production.
He opined that, in Nigeria poultry feed trial has shown that if cassava roots and leaves were combined in a ratio of four to one, the mixture could replace maize in poultry feed and reduce feed cost litreature loss in weight. But the presence of iron and copper lterature Cocoyam make it an important food to prevent anemia and boost circulation throughout the body. Cassava undergoes post-harvest physiological deterioration, or PPD, once the lietrature are separated from the main plant.
It was observed that all the literature properties studied weight, diameter and spread ratio decreased with increasing levels of pigeon pea flour. Remember me on this computer.
In Nigeria, because of an array of reasons, the composite cassava and wheat flour food products are more expensive than all wheat flour. The geographical distribution of colocasia species indicates that the genus is naturally distributed from South Asia to Southeast Asia revifw China and Indonesiain lowland tropics areas as well as in the cooler conditions of the Himalayan mountains [ 28 ].
Breeding programs of Taro were initiated in late s with varietal releases recorded in Fiji inSamoa in andSolomon Islands in andPapua New Guinea in and India in [ 7879 ].
Evidence equally indicate human use of the plants 28, years ago in the Solomon Islands [ 23 ]. J Agric Econ Dev.
