Soil Organic Carbon and Nitrogen Fractions and Sugar Beet Sucrose Yield in Furrow-Irrigated Agroecosystems
(2015-03)Soil organic matter (SOM) fractions were determined using extraction-, incubation-, and density-based fractionation techniques on samples collected from a range of furrow-irrigated sugar beet (Beta vulgaris L.) ... -
Potential of deterministic and geostatistical rainfall interpolation under high rainfall variability and dry spells: case of Kenya’s Central Highlands
(Springer, 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 ... -
Using Apsim-Model as A Decision-Support-Tool for Long-Term Integrated-Nitrogen-Management and Maize productivity under Semi-Arid Conditions in Kenya
(Cambridge University Press, 2015-04)There is continued decline in per capita agricultural productivity in the drier parts of Kenya’s central highlands. The declines have been linked to low and declining soil fertility, soil water, high atmospheric heat, ... -
Potential side effects of biocontrol and plant-growth promoting Bacillus amyloliquefaciens bacteria on earthworms
(Elsevier, 2015-08)Many bacteria strains are now successfully used for plant-growth promotion (PGPR) and as biocontrol agents (BCA) against plant diseases. Mechanisms behind their action involve production of enzymes and antibiotics, which ... -
Applicability of conservation agriculture for climate change adaptation in Rwanda’s situation
(Academic Journals, 2015-09)Improving food security and environmental conservation should be the main targets of innovative farming systems. Conservation agriculture (CA), based on minimum tillage, crop residue retention and crop rotations has been ... -
Impact of reduced tillage and crop residue management on soil properties and crop yields in a long-term trial in western Kenya
(2015-11)Sustainable farming practices are required to address the persistent problems of land degradation and declining crop productivity in sub-Saharan Africa (SSA). Approaches such as reducing tillage and retaining crop residues ... -
Inoculated Soybean Yields Response to Nitrogen and Phosphorus Application
(SCIENCEDOMAIN international, 2016)Inherent low soil nitrogen (N) and phosphorus (P) is one of the major hindrances of increased soybean productivity in Malawian soils. Although, inoculation of legumes with rhizobia, has been advocated for decades as a ... -
Planting Pits’ Effects on Soil Nutrients in a Sorghum and Pigeon Pea Rotation in Semi-arid Areas of Eastern Kenya
(Science Domain International, 2016-12)Planting pits are rain water harvesting structures that trap water and nutrients in surface runoff and rain water falling directly into the pits. Planting pits have been promoted for improving crop yields without considering ... -
Inter-seasonal Effects on Selected Maturity Parameters of DK8031 Maize Grown under Varying Irrigation and Nitrogen Levels in Embu County, Kenya
(2017-07)Maize is a staple food and a source of carbohydrates to a large proportion of people in Kenya. The performance of crop plants such as maize depends on a number of factors such as climate, soil characteristics and plant ... -
From Shiny Shoes to Muddy Reality: Understanding How Meso-State Actors Negotiate the Implementation Gap in Participatory Forest Management
(Taylor and Francis Online, 2017-11)Recent research on participatory forest management (PFM) in the global south has highlighted the existence of a widespread “implementation gap” between the ambitious intent enshrined in legislation and the often partial, ... -
Evaluating the surface functional groups on banana leaf petioles and the resultant biochar for potential adsorbance
(JMES, 2020)The presence of surface functional groups is key to the performance of an adsorbent material. The aim of this study was to evaluate the presence of functional groups on banana leaf petiole and on biochar made from ... -
The response of soil physicochemical properties to tillage and soil fertility resources in Central Highlands of Kenya
(Pagepress, 2020)To attain agricultural sustainability, use of soil resources and tillage requires equal consideration for chemical and physical components of soil fertility. We assessed responses of selected soil physical and chemical ... -
Development of a Water Quality Assessment Index for the Chania River, Kenya
(Taylor and Francis, 2020-11)Human-related activities are known to have deleterious effects on the water quality of aquatic ecosystems, but there is limited information on the impact of these on rivers in tropical regions, such as the Chania River ... -

Suitability of different data sources in rainfall pattern characterization in the tropical central highlands of Kenya
(Heliyon, 2020-11)Uncertainty in rainfall pattern has put rain-fed agriculture in jeopardy, even for the regions considered high rainfall potential like the Central Highlands of Kenya (CHK). The rainfall pattern in the CHK is spatially and ... -
Soil nutrients and crop yield response to conservation-effective management practices in the sub-humid highlands agro-ecologies of Kenya
(Heliyon, 2021)Crop productivity in most smallholder farming systems in Sub-Saharan Africa experience low use of soil amendment resources, low and erratic rainfall, frequent dry spells, and droughts. Rain-fed agriculture has a high crop ... -
Phosphorus availability and exchangeable aluminum response to phosphate rock and organic inputs in the Central Highlands of Kenya
(Heliyon, 2021)Soil acidity and phosphorus deficiency are some of the constraints hampering agricultural production in tropical regions. The prevalence of soil acidity is associated with phosphorus (P) insufficiency and aluminum ... -
