Looking for convergence: Stakeholders’ perceptions of cocoa extension constraints in Ghana

This study was undertaken with the objective of evaluating the extent of convergence on the part of key stakeholders in the cocoa sector on the problems of cocoa extension and how to address it. The study was carried out in the Atwima Mponua and Amansie West districts of the Ashanti regionin 2008 although some of the stakeholders interviewed were outside these districts. Survey research methodology was employed including focus group discussions to obtain information from policy makers, researchers, extensionists, licensed buying companies, input dealers and farmers. The key findings were that all concurred that productivity should be boosted to improve the lot of farmers and that information provision is central to this. However, there was no convergence as to how this could be achieved. It emerged that the state of cocoa extension was deplorable requiring urgent policy intervention. The implications and conclusions are that farmers are not benefitting sufficiently from many years of cocoa research; to move productivity to a higher pedestal, the acknowledged knowledge gap between researchers and farmers need to be bridged

Yam pests in the Ashanti and Brong Ahafo regions of Ghana: A study of farmers\' indigenous technical knowledge and control practices

In Ghana, yam is a very important indigenous subsistence and cash crop that is now the most popular nontraditional export food crop, despite years of scientific neglect. There is a general paucity of technical information on yam production and marketing constraints, but especially so for pests and their management. To understand and document farmers\' needs as a basis for developing technologies to meet their requirements, this study surveyed yam farmers\' indigenous technical knowledge about pests on their crops and their pest management practices over the years in two districts in Brong Ahafo Region and one in Ashanti Region. Pre-tested questionnaire were administered to 30 randomly selected farmers in five villages in each district. The results showed that farmers\' knowledge about pests and the pest spectra were similar for the three districts. Farmers knew about insect pests on their yams, but were neither able to draw interrelationships between pest populations and damage nor the cultural practices that they follow or the ecological state of their farms. Termites (Amitermes spp., Macrotemes spp., and Microtermes spp.) were considered more important pests than millipedes (Peridontoyge spp.), tuber beetles (Heterolygus meles and Prionorcytes rufopiceus), mealybugs (Pseudococcus brevipes, Planococcus dioscorea and Ferrisia virgata), and scale insects (Aspidiotus destructor and Aspidiella hartii) in that order. Out of 12 white yam varieties cultivated in the area, “Pona” was identified to be most susceptible to pest attack and “Dentepruka” least susceptible. Anthropological factors such as farmer's origin or residency status, level of education, age, marital status, family size, and the land tenure system were also found to play key roles in the technologies adopted in cultivating yams. The implications of the findings, particularly in identifying appropriate experimental variables for technology generation and transfer to improve yam resource productivity, are discussed

Adoption of improved cowpea (Vigna unguiculata (L.) Walp) technologies in Ghana

The Ghana Grains Development Project has developed and disseminated improved cowpea production technologies to farmers in Ghana since 1985. These technologies were improved varieties, row planting, and the use of pre- and post-flowering insecticides. To assess the extent of adoption of these technologies by farmers, eight cowpea production districts were surveyed across four agro-ecological zones in 1995 in Ghana. A random sample of 313 cowpea farmers participated in the survey. Results indicated that 70 per cent used recommended pre-flowering insecticides, and 26 per cent adopted post-flowering insecticides across the ecological zones. The highest adoption rate for improved varieties was observed in the Forest Zone (97 %). The adoption of row planting was highest in the Forest Zone (100 %), followed by the Guinea Savanna Zone (92 %), and lowest in the Coastal Savanna Zone (58 %). Most farmers agreed that by adopting improved production technologies, their yields and overall production increased, and they made more profit from cowpea cultivation.The whole family participates in various activities associated with cowpea production. However, men do strenuous work like land preparation, weeding and spraying of insecticides, while women and children participate in less strenuous work such as planting, harvesting and threshing. Le Project de Développement des Grains du Ghana a developpé et disséminé les technologies de la production de dolique amélioré aux cultivateurs au Ghana depuis 1985. Ces technologies étaient les variétés améliorées, la culture en lignes et usage d'insecticides avant et après la floraison. Pour évaluer le degré d'adoption de ces technologies par les cultivateurs, un sondage a été entrepris en 1995 en 8 districts de production de dolique à travers quatre zones agro-écologique au Ghana. Un échantillon pris au hasard de 313 cultivateurs de dolique participaient au sondage. Les résultats indiquaient que 70% utilisaient les insecticides d'avant floraison recommandés et 26% adoptaient les insecticides d'après floraison à travers les zones écologiques. La proportion d'adoption la plus élevée pour les variétés améliorées était observée dans la zone forestière (97 %). L'adoption de la culture en lignes est la plus élevée dans la zone forestière (100 %) et suivi par la zone savane-guinéenne (92 %) et la plus faible dans la zone savane-littorale (58 %). La plupart de cultivateurs étaient du même avis que par l'adoption des technologies de production améliorée, leur rendements et la production globale augmentaient, et ils avaient tiré plus de bénéfice de la production de dolique. Toute la famille participent aux activités différentes liées à la production de dolique. Cependant le travail ardu tel que la préparation de terre, le désherbage et la pulvérisation d'insecticide sont faites par les hommes alors que les femmes et les enfants participent aux travaux moins ardus tels que la plantation, la moisson et la battage.
