Influence of seed size on the germination of four cowpea (Vigna unguiculata (L) Walp) varieties

A study was conducted to investigate how seed size affects germination and vigor of cowpea seeds. Four cowpea varieties, (Asontem, Nhyira, Soronko and Tona), were obtained from Crops Research Institute of the Centre for Scientific and Industrial Research (CSIR-CRI). The seeds were grouped in two sizes (large and small), by manually sorting by length, width and thousand seeds weight. Laboratory experiments were carried...

Striga infestation and its interaction to density of sorghum, basic chemical and physical properties of the soil across Tigray Region, Northern Ethiopia

In Ethiopia, sorghum is the major crop next to teff grown all over the country. Though the productivity of sorghum has increased in the last few years, the overall national productivity of sorghum is low (2.106 t/ha) compared to the average production of 2.3 t/ha of developed countries. The low productivity of sorghum is attributed mainly to infestation by Striga. The annual yield loss and geographic distribution of...

Effect of poultry manure and NPK on yield and storability of orange-and white-fleshed sweet potato [Ipomoea batatas (L.) Lam]

Sweet potato [Ipomoea batatas (L.) Lam] is amongst the most commonly grown root crops in Sub-Saharan Africa. Comparatively,orange-fleshed cultivars of sweet potato are richer in beta carotene, a precursor to dietary vitamin A than white-fleshed ones. In spite of their health benefits, yields have been low in Africa due to low soil fertility. Studies were therefore conducted to determine the effect of amending soils with...
