Assessing the impact of climate change and climate variability on agricultural productivity in selected climatological zones of Uganda: an overview.
(RUFORUM, 2010-09)
Climate change and climate variability are a major threat to livelihoods in sub-Saharan Africa (SSA). The IPCC report of 2007 indicates that SSA is the most vulnerable region to climate change and climate variability due ...
Nitrogen fixation by common bean (Phaseolus vulgaris L.) in pure and mixed stands in semi-arid south-east Kenya
(Science Direct, 2001-01)
Research was carried out in the field on the effect of intercropping common bean and maize crops in a semi-arid zone of south-east Kenya over two rainy seasons in 1997. The experimental design was a randomised complete ...
Potential of deterministic and geostatistical rainfall interpolation under high rainfall variability and dry spells: case of Kenya’s Central Highlands
(Springer Verlag, 2015-03)
Drier parts of Kenya’s Central Highlands endure persistent crop failure and declining agricultural productivity. These have, in part, attributed to high temperatures, prolonged dry spells and erratic rainfall. Understanding ...
Perception and Use of Climate Forecast Information Amongst Smallholder Farmers in Semi-Arid Kenya
(Knowledgia Scientific, 2008)
This study investigates perception and use of seasonal forecast and the influence of the 2004 October-December (OND) seasonal forecast on agricultural decision-making amongst smallholder farmers in semi-arid Kenya, in ...
Hydro-Geomorphologic Impact Assessment and Economic Viability of Smallholder Farms In Muooni Catchment, Machakos District.
(Journal of Agri - Food and Applied Sciences, 2013-12)
Water depletion, sheets, rills, inter-rills and big gullies have an impact on water and land productivity in a catchment area, endangering thus substantial wealth creation in agriculture. An assessment of 66 farms selected ...
Economic analysis of maize-tepary bean production using a soil fertility replenishment product (PREP-PAC) in semi-arid Eastern Kenya
(WFL publisher, 2005-04)
Continuous cropping without external nutrient inputs to soils has led to the expression of poorly productive patches in farmers’ fields in semi-arid Eastern Kenya. The smallholder farmers attempting to correct these ...
Phenology and Diurnal Course of Leaf Water Potential of Three Bean Varieties under a Semi-Arid Environment in South-East Kenya
(Faculty of Science Kenyatta University, 1998)
The objectives of this study were to observe the phenology and to investigate the diurnal behaviour of leaf water potential (LWP) in three bean varieties under irrigated and unirrigated treatments with a view to making ...
Across-sectional survey of prevalence and correlates of couple sexual concurrency among married couples in fishing communities along Lake Victoria in Kisumu, Kenya.
(Sexually Transmitted Infections, 2013-10)
OBJECTIVE:
Sexual concurrency has been associated with HIV infection. Since HIV in sub-Saharan Africa is mostly spread within the context of heterosexual couples, it is necessary that intervention is focused on such ...
Spatial Variation in Soil Organic Carbon within Smallholder Farms in Western Kenya: A geospatial Approach
(2006)
In many farming landscapes across Sub-Saharan Africa (SSA), soil fertility has been on the decline with significant implications on crop productivity. However, even with such a decline, soil nutrient levels still differ ...
Nitrogen Fixation by Vigna radiata L. Wilczek in Pure and Mixed Stands in SE-Kenya
(CSA Illumina, 1999)
Greenhouse and field experiments were carried out to determine the number of rhizobia in soils of SE-Kenya, nodulation and nitrogen fixation by green grams in two cropping systems was also determined. The Most Probable ...
