Teff [Eragrostis teff (Zucc.) Trotter] is native to Ethiopia. Self-pollinated warm season annual grass with the advantage of C4 photosynthetic pathway and tetraploid 2n=40 plant/crop. Countries like USA, Canada, Australia, Netherlands, South Africa and Kenya produce teff for different purposes such as forage crop, thickener for soups, stews and gravies. The largest production of Teff in the world is from Ethiopia where annually, above 6,562,325 farmers grow Teff on above 2.87 million hectares, which is about 22.95% of the total cultivated land in the country.
The continuous discharge of effluents into Warri River, impacts on its water quality parameters as well as plankton species which requires commensurate surveillance. This study focuses on its physicochemical characteristics and their influence on plankton composition and abundance. The surface water samples and plankton collected monthly from June to November 2014 were analyzed using standard methods. The physicochemical parameters showed variations among the stations. The ANOVA results revealed that water temperature, transparency, turbidity, TDS, conductivity, pH, acidity, Dissolved Oxygen and phosphate were significantly different (P <0.05) among the studied sites.
The increasing concentration of carbon in the atmosphere is a serious environmental problem that can affect living system on earth. The increase in greenhouse gas emissions caused global warming that will affect the world climate change and rising sea levels. Climate change will disrupt farming system in both the micro and macro scale. Estimation of forest carbon emissions is one of the important efforts to reduce climate change.
This study tested the influence of substrate type, size surface and application of IBA auxin on rooting of stem cutting leaf of Anonidium mannii, a wild fruit species with low seed germination rate. Two trials were conducted. The first tested three substrate types that are sand, wood sawdust and rice husks. We also tested combinations of these substrates (2:2), resulting in six treatments in a randomized complete block design.
N Wheat (Triticum aestivum) production in Kenya has been severely affected by stem rust Ug99 and its related race groups. The consequence of not controlling this disease is steep decline in the crop production thus creating food insecurity to over 70% of the small-scale holder farmers who depend on it as a source of food as well as income. The causative agent of the diseasePucciniagraminis f. sp tritici (Pgt) has been studied by researchers globally because of its rapid evolution of races within lineage overcoming existing resistant genes.
