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

Molecular evidence of incipient speciation within Anopheles gambiae s.s. in West Africa [PDF]

, 2001
We karyotyped and identified by polymerase chain reaction restriction fragment length polymorphism (PCR-RFLP) analysis Anopheles gambiae s.s. samples collected in several African countries. The data show the existence of two non-panmictic molecular forms,

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 ...

Conservation Agriculture Improves Soil Quality, Crop Yield, and Incomes of Smallholder Farmers in North Western Ghana

Frontiers in Plant Science, 2017
Conservation agriculture (CA) practices are being widely promoted in many areas in sub-Saharan Africa to recuperate degraded soils and improve ecosystem services. This study examined the effects of three tillage practices [conventional moldboard plowing (

Generation mean analysis of the key earliness related traits in cowpea (Vigna unguiculata (L.) Walp)

Scientific African, 2022
The nature of gene action controlling agronomic traits enables plant breeders to execute a successful crop improvement programme. To elucidate the type of gene action governing the key earliness related traits in cowpea, seven populations of the six ...

Resource partitioning among African savanna herbivores in North Cameroon: the importance of diet composition, food quality and body mass [PDF]

, 2011
The relationship between herbivore diet quality, and diet composition (the range of food plants consumed) and body mass on resource partitioning of herbivores remains the subject of an ongoing scientific debate.
