Kolanut production, processing and marketing in the South-eastern states of Nigeria

Kolanut is an important economic crop in the South Eastern region of Nigeria. However, there were no contiguous kola plantations in the South East, rather each homestead has about 2 to 15 kola trees scattered around the backyard. The land tenure system was observed to be the major constraint to kola production in large scale in the South East. Other limiting factors were poor nutrient status of the South Eastern soils,...

Heavy utilization significantly reduced tree basal area, biomass and plant densities in central Omusati, leading...

Relationship between total anthocyanin level and colour of natural cherry laurel (Prunus laurocerasus L.) fruits

The total anthocyanins level and fruit colour were investigated in twelve naturel cherry laurel (Prunus laurocerasus L.) genotypes. Anthocyanins are well-noted as healty compounds due to their antioxidant properties. Fruit samples of cherry laurel were examined for their total anthocyanin content by using a spectrophotometric differential pH method. Cherry laurel genotypes showed differences in their total...

Costs analysis and toxicity of Jatropha curcas L. on maize weevil, Sitophilus zeamais Motsch

The toxicity of Jatropha seed oil to maize weevil, Sitophilus zeamais Motsch. in stored grains was tested in the laboratory. The cost analysis of seed oil extraction was estimated. The rates of seed oil treatment at 0.2, 0.5 and 1.0 ml and the untreated control for storage of 100 g grains were replicated four times. Each experimental unit contained five pairs of freshly emerged adult S. zeamais....
