Producing White Yam for the Export Market: The influence of Seed Sett Size and Planting Density on Tuber Sizes
The study was conducted to evaluate the effect of seed sett sizes and planting density on the tuber size and yields of yam. The treatments were arranged in a split-split plot design with two premium Dioscorea rotundata varieties (Pona and Dente) as main plot. Seed sett sizes (farmers' sett size 350 g, half farmers' sett size 175g) as subplot and Planting density (6944 plt/ha; 8333 plt/ha; 10417plt/ha; 13889 plt/ha; 20833 plt/ha) as sub-sub plot in 2014. Minisetts (50 g) a popular yam multiplication technique was added in 2015. -
Marginal Rate Of Returns of Local and Improved Open Pollinated Maize Varieties Compared With Quality Protein Maize Hybrids in Ghana.
Maize variety development in Ghana in the past mainly concentrated on developing open-pollinated varieties (OPVs). Since malnutrition especially protein deficiency is a major problem amongst most children in Ghana and for higher grain yields it was prudent that Quality Protein Maize (QPM) hybrids be developed. -
Reduced tillage practices without crop retention improved soil aggregate stability and maize (Zea mays L.) yield
Conservation agriculture has been advocated as an effective option for maintaining soil and environmental sustainability. However, the current farmer practice in Western Loess Plateau involves removal of crop residues. This study evaluated the influence of tillage systems without residue retention on soil properties and maize (Zea may L.) yield. -
Genetic Variability of Cassava Progenies Developed through Introgression of Cassava Mosaic Disease Resistance into Ghanaian Landraces
Availability of genetic diversity is important in selecting suitable cultivars for crop improvement. Progenies of crosses between 19 farmer-preferred cassava landraces and Cassava Mosaic Disease (CMD)-resistant cultivar TME 11 were evaluated and compared with their maternal parents to assess their genetic variability and genetic gains based on CMD tolerance, some growth variables and root yield. -
Farmer participatory evaluation of eight elite clones of cocoyam (Xanthosoma sagittifolium L. Schott)
Twenty cocoyam farmers from the Ejisu-Juabeng municipality were involved in a farmer participatory on-station evaluation of cocoyam at Fumesua (a rainforest agro ecological zone of the Ashanti Region of Ghana) for 2 years (2009-2010) major growing seasons). -
Hygienic, affordable and environmentally friendly water packaging container
Disposable plastic drink containers are a major global environmental problem. In many countries, Coca-Cola and other drinks are packaged in non-disposable glass bottles.
