Evaluation of elite soybean (Glycine max L.) genotypes for nitrogen nutrition, water use efficiency and grain yield in the Guinea Savanna Agro Ecological Zone of Northern Ghana
Nitrogen is essential due to its function in plant growth and development. It is a component of DNA and proteins which are the building blocks of life. Nitrogen is one of the most limiting factors for crop production. The need to meet the huge nitrogen requirement has necessitated the use of synthetic fertilizer. However, its continued application affects soil health, environment, and agricultural sustainability....
Screening for yield-related agronomic traits in a panel of locally conserved common bean (Phaseolus vulgaris L.) accessions
Characterization and conservation of germplasm is a critical step toward the genetic improvement of the crop. This study assessed variation in 257 common bean genotypes which included 207 accessions obtained the National Gene Bank of Kenya, 33 accessions from Kenya Agricultural and Livestock Research Organization (KALRO), 13 landraces collected from farmers’ fields and four commercial varieties for various...
Nutritional and phytochemical characterization of taro [Colocasia esculenta (L.) Schott] germplasm from Burkina Faso
Taro (Colocasia esculenta (L.) Schott) is a food crop mainly produced for its nutrient-rich corms. This study aims to characterize the nutritional and antioxidant potential of fifty-nine genotypes of taro to identify the most interesting chemotypes. The traits evaluated were: starch, proteins, soluble sugars, total phenolics, flavonoids, and antioxidant capacity, assessed by Ferric reducing antioxidant power (FRAP) and...
Genetic bio-fortification of cereals from a plant breeding perspective
Genetic “biofortification” presents an opportunity to provide sustainable and cost effective solution to the perennial problem of ‘hidden hunger’ prevalent in most marginalized regions of the world. Diets in households across many developing countries typically consist of high calorie crops which are mostly cereals with limited diversified food. Production of cereal crops with elevated quantities...
