“…In spite of the high prevalence of insect pests in yam (Dioscorea spp.) production, for instance, farmers (97%) did not practice any type of pest control because they lacked the knowledge of appropriate control methods [23]. A similar study in Frafra potato (Solenostemon rotundifolius Poir.)…”

Sweet potato has gained prominence due to its ability to adapt to wide production ecologies and yield response to minimal external inputs. Orange-fleshed cultivars in particular have immense potential to improve household income and nutrition in sub-Saharan Africa. However, the sweet potato value chain (SPVC) is not well-developed in many producing countries. The study was conducted in two regions to characterize the production operations as well as identify opportunities to propel the SPVC in Northern Ghana. Data were collected using mixed methods including structured questionnaires via face-to-face interviews. Analysis of strengths, weaknesses, opportunities, and threats (SWOT) was conducted at multistakeholder platforms with different actors. Gross margin profit and benefit-cost ratios were determined by using six cost variables. Overall, the industry was largely a fresh produce market, targeting food vendors, processors, and direct selling to wholesalers, retailers, and household consumers. The SWOT analysis revealed wide-ranging opportunities including favourable production ecologies, processing options, and insatiable local and international markets. The institutional actors need to network the primary actors to synergistically operate with a collective profit motive. The most prioritized production constraints such as access to seed, cost of chemical fertilizer, short shelf-life, field pests and diseases, and declining soil fertility should be addressed.

These include parasitic nematodes; insects such as leaf and tuber beetles; fungi such as leaf spot, tuber rot, and other viruses (Asante et al, 2007;IITA, 2009;Zaknayiba and Tanko, 2013). Insuffi cient farm inputs and modern technologies are also constraints to yam production in developing countries like Nigeria, Ghana, Côte d'Ivoire, Benin and Togo.…”

Yams as a stable food crops do not only serve as integral vehicle for food security, but also as a source of income, and employer of labour in the producing areas in Nigeria. Lack of fi nance, inadequate farm inputs, storage facilities and high cost of labour are identifi ed as the primary constraints to yam production in the country. This article deals with most of the determinants of yam production, constraints and the importance yam products in Nigeria. The fi ndings of the study suggest that farm size, producer price, fertilizer use, yield (Hg/Ha), and economic growth have a positive infl uence on yam production in Nigeria. On the contrary, the result shows an inverse relationship between commercial loans and yam production in the country. There is an urgent need for the Nigerian government to provide a conducive environment and investment climate by subsidising farm inputs and providing aff ordable loans to the smallholder yam farmers for a sustainable production.

“…The period that the farmers had engaged in farming activities ranged from 1 year up to more than 40 years. Majority of farmers in Ghana being illiterate was reported by Asante et al, (2007). However, this could be the reason why they have hang out on farming for longer periods.…”

During surveys on anthracnose disease of cassava and yam, farmers were interviewed through questionnaire to seek their knowledge of the disease in four ecological zones in Ghana (Forest, Transition, Guinea Savannah and Coastal Savannah). Results analysed indicated that over 61% of the yam farmers and 79% of cassava farmers have good knowledge of anthracnose diseases. The farmers were aware that the disease occur on the leaves and stems of cassava and also on the leaves and vines of yam. More than 50% of the farmers said that wet seasons are the period where the disease spread most. In all the ecological zones, more than 55% of the farmers indicated that the disease has negative effect on their produce yet more than 60% of the farmers did not have any idea as to the causes of the disease and do not undertake any control method to manage the disease. The work has revealed that farmers may know about diseases due to long periods of farming, their knowledge on the causes and control of cassava and yam anthracnose disease is inadequate and therefore need more education.
