Mixed Cropping System on Diversity and Density of Plant Parasitic Nematodes
The potential of mixed cropping system on the diversity and suppression of nematodes was investigated at two locations in Ghana. -
Influence of Seed Storage Techniques on Germinability and Storability of Cowpea (Vigna unguiculata (L) Walp)
This study was set to investigate the germinability and storability of the newly released cowpea genotypes and secondly the influence of different storage materials under ambient storage condition on seed vigour and germination over time. -
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. -
Interspecific Competition and Grain-Hosts Selection of Maize Weevil, Sitophilus zeamais (Motsch.) (Coleoptera; Dryophtoridae) and Larger Grain Borer, Prostephanus truncatus (Horn) (Coleoptera; Bostrichidae)
Laboratory interspecific competition and grain-hosts selection experiments involving maize weevil (MW), Sitophilus zeamais (Motsch.) and larger grain borer (LGB), Prostephanus truncatus (Horn) were performed under ambient temperature and relative humidity (25˚C - 35˚C and 70% - 80% relative humidity) in their major host cereal, maize grains. -
Signalization options to improve capacity and delay at roundabouts through microsimulation approach: A case study on arterial roadways in Ghana.
Roundabouts are very useful when flows are balanced but can have operational challenges when flows increase. Most roundabouts on arterial roadways in Ghana experience recurring congestion during peak traffic. The four roundabouts between Ejisu Municipality and Asokwa Municipality on the N6 highway are typical of the situation found on arterials countrywide. -
