Survey of fungal diseases associated with amaranth (Amaranthus species) in peri-urban vegetable farms in Kumasi and Tamale metropolis of Ghana

Amaranthus species is an important leafy vegetable in Ghana; however, foliar diseases of the crop reduce the marketable and edible portions as well as income to farmers. To facilitate the development of disease management strategy, there is the need to document various diseases limiting amaranth production. In view of this, surveys were carried out in forty-three peri-urban vegetable farms in the Kumasi and Tamale...

Taurine is a future biomolecule for potential health benefits: A review

Taurine is a sulfur-containing amino acid that is converted to a neutral beta-amino acid, chemically known as (2-Amino-ethane sulfonic acid) having chemical formula C2H7NO3S. It was first isolated from Ox bile, and thus derives its name from the Latin word “Taurus”, meaning 'ox' or 'bull'. This is the only amino acid that is extensively found in animal tissue. The richest source of taurine is...

Exploring the drivers of technical efficiency in Senegal’s agricultural production sector

Most agricultural farmers in Senegal make limited use of key agricultural inputs such as fertilizers, certified seeds, irrigation, mechanization and pesticides. Such situation happens in a context where most farmers are exposed to droughts, land degradation, and erratic climatic shocks. These factors typically lead to negative effects on technical efficiency, and therefore unfavorable outcome results in terms of food...
