Selective breeding of Nile tilapia, Oreochromis niloticus: A strategy for increased genetic diversity and sustainable development of aquaculture in Kenya
(Taylor & Francis, 2021)The aquaculture subsector is important in Kenya for food and nutritional security. The rapid growth of the subsector is evident especially in the widespread culture of Nile tilapia (Oreochromis niloticus); however, the ... -
The prospects of biofloc technology (BFT) for sustainable aquaculture development
(Elsevier, 2021)As capture fishery sector continues to decline, aquaculture industry must be accelerated to bridge the fish supply gap especially in the developing countries. However, in most devel- oping countries, aquaculture sector ... -
Effects of Integrated Use of Calliandra calothyrsus and Maize Stover with Urea on Maize Yield Components under Striga Infestation in Western Kenya
(Research Gate, 2020)The effect of integrated use of Calliandra or maize stover with urea on Striga infestation and maize yield components was assessed in a field experiment carried out for five consecutive seasons on a clay loam Ferralsol in ... -
The effectiveness of local strains of Fusarium oxysporium f. Sp. Strigae to control Striga hermonthica on local maize in western Kenya
(Wiley, 2020)Striga hermonthica weed infestation continues to persist among smallholder poor farmers in Kenya who depend on traditional maize (Zea mays L.) seeds for their livelihood. The purpose of this study was to evaluate the ... -
Effect of nitrogen application on the expression of drought-induced root plasticity of upland NERICA rice
(Taylor & Francis, 2019)This study evaluated the effect of three N fertilization levels 60 (low), 120 (medium), and 180 (high) kg N ha−1 and soil moisture content gradients created by a line-source sprinkler on the expression of plasticity in ... -
Interactive influence of rainfall manipulation and livestock grazing on species diversity of the herbaceous layer community in a humid savannah in Kenya
(Elsevier, 2019)Changes in rainfall regime and grazing pressure affect vegetation composition and diversity with ecological implications for savannahs. The savannah in East Africa has experienced increased livestock grazing and rainfall ... -
Ecosystem productivity and CO2 exchange response to the interaction of livestock grazing and rainfall manipulation in a Kenyan savanna
(Elsevier, 2021)Savanna ecosystems in Kenya are experiencing altered rainfall amount and increased grazing pressure. These environmental alterations occur simultaneously and impact on productivity and CO2 exchange of the savanna in unclear ... -
Mineral nutrient uptake of maize and banana in an intercrop with agroforestry tree species in Vihiga County, Kenya
(IAR Journal of Agriculture Research and Life Sciences, 2021)Western Kenya faces high population pressure and this has increased demand for food. Smallholder farmers in the region have been forced to practice poor farming practices such as continuous cultivation and clearing of ... -
The social and economic diversity of the coffee-banana farming system and technology uptake in Central Uganda
(American Journal of Agricultural Research, 2021)Food systems of the future that will guarantee food and nutrition security of millions of poor farming households will have to be both economically and socially diverse. Diversity of farming systems acts as a catalyst ... -
Field Characterization of Partial Resistance to Gray Leaf Spot in Elite Maize Germplasm
(The American Phytopathological Society, 2020)Forty-eight inbred lines of maize with varying levels of resistance to gray leaf spot (GLS) were artificially inoculated with Cercospora zeina and evaluated to characterize partial disease resistance in maize under field ... -
Response of soybean (Glycine max L.) to application of lime and phosphate fertilizer in an acid soil of western Kenya
(Archives of Agriculture and Environmental Science, 2020)The effect of combining lime and phosphate fertilizer on the performance of soybean (Glycine max L.) was investigated in a pot experiment consisting of nine treatments of three rates of lime (0, 4 and 8 t ha−1) in a factorial ... -
