Stability of Sources of Resistance to Cowpea Aphid (Aphis craccivora Koch, Hemiptera: Aphididae) across Major Cowpea Production Zones in Ghana

International Journal of Agronomy, 2020
Aphids (Aphis craccivora Koch) are an important vegetative stage pest of cowpea in Africa. The use of resistant cultivars is among the best management option for this pest, but the success of this strategy is influenced by the stability of the resistant ...

Postharvest losses and mitigating technologies: evidence from Upper East Region of Ghana

Sustainable Futures, 2021
Post-harvest losses (PHL) have been identified as a crucial challenge to achieving food and nutrition security in sub-Saharan Africa. Access to reliable data and standardized methods of estimating PHL are a twin barrier to developing long term mitigation

Analysis of genotype by environment interaction for grain yield of intermediate maturing drought tolerant top-cross maize hybrids under rain-fed conditions

Cogent Food & Agriculture, 2017
Maize plays a crucial role in combating food insecurity in Ghana due to its high yield potential and wide adaptability. Thirty five intermediate maturing maize hybrids were evaluated at eight locations in Ghana for two years (i) to determine grain yield ...

Performance of maize populations under different nitrogen rates in northern Ghana

Annals of Agricultural Sciences, 2018
This study evaluated grain yield performance, stability and agronomic nitrogen-use efficiency (AE) of twelve maize populations under three nitrogen (N) rates at two locations in the Guinea and Sudan savannah zones of Ghana in 2014 and 2015.

Genetic characterization and population structure of maize populations using SSR markers

Annals of Agricultural Sciences, 2019
Maize is a major staple food in sub-Saharan Africa. However, due to the threats posed by biotic and abiotic constraints to its production, it is a prerequisite to conserve germplasm with diverse genetic background and to seek for favourable genotypes ...
