INTEGRATION OF TIED RIDGES AND FERTILIZER USE TO ENHANCE WATER AND NITROGEN USE EFFICIENCIES FOR MAIZE PRODUCTION IN SEMI-ARID LANDS
(University of Eldoret, 2025)Low maize (Zea mays L.) production in arid and semi-arid lands (ASALs) has been attributed to inadequate soil moisture and declining soil fertility. This could be improved through enhanced water use efficiency (WUE) and ... -
THE EFFECTS OF FARMERS GROUP PERFORMANCE ON HOUSEHOLD FOOD SECURITY IN WESTERN KENYA
(University of Eldoret, 2025)Many developing countries have reintroduced farmer groups into their policy agenda due to their role in accelerating technical and economic change in rural areas. In Kenya, however, farmer groups remain inadequately ... -
EFFECT OF WONDERGRO- A SOIL CONDITIONER FOR ENHANCING DI- AMMONIUM PHOSPHATE (DAP) USE EFFICIENCY IN MAIZE PRODUCTION
(University of Eldoret, 2025)Despite maize being considered a staple food crop in Kenya, its productivity is low mainly due to inappropriate soil fertility management, especially in smallholder systems. The continuous decline in soil fertility is a ... -
FATE OF NITROGEN FERTILIZER IN RAINFED MAIZE SYSTEMS OF TROPICAL HIGHLANDS OF KENYA
(University of Eldoret, 2025)Crop production in sub-Sahara Africa (SSA) is often constrained by declining soil fertility associated with negative nutrient balances as a result of continuous cropping with little or no replenishment of nutrients. To ... -
GREENHOUSE GAS EMISSIONS, SOIL PHYSICOCHEMICAL PROPERTIES, AND NUTRIENT USE EFFICIENCY UNDER INORGANIC-ORGANIC FERTILIZER SUBSTITUTIONS IN MAIZE AND DESMODIUM CROPPING SYSTEMS
(University of Eldoret, 2025)Climate change continues to threaten ecosystem functions, and agriculture remains one of the major sources of greenhouse gas (GHGs) emissions responsible for global warming. However, little is known about the quantities ... -
SPATIOTEMPORAL DYNAMICS OF RIPARIAN GREENHOUSE GAS FLUXES AND SOIL CARBON STOCKS IN THE BURA AND WUNDANYI CATCHMENTS, KENYA
(University of Eldoret, 2025)Agropastoral riparian zones are globally linked to increased greenhouse gas (GHG) emissions and soil organic carbon (SOC) depletion, but the Kenyan cases are underrepresented in global datasets. The study investigated ... -
EFFECT OF PHOSPHORUS FERTILIZER AND CROPPING SYSTEMS ON RICE BEAN (Vigna umbellata, L.) PRODUCTION IN WESTERN KENYA
(University of Eldoret, 2025)Low soil phosphorus (P) remains a critical constraint to sustainable legume production in Western Kenya. Rice bean (Vigna umbellata L.), a resilient and nutrient-rich yet underutilized legume, offers opportunities for ... -
Socio-Economic Factors Influencing Solid Waste Management in Urban Centres of Nandi County
(African Journal of Education Science and Technology AJEST, 2025)Rapid population growth, urbanization, industrialization and economic development have resulted in the generation of big volumes of solid waste in Nandi County. Yet solid waste is an economic commodity that may not ... -
Economic Value of Solid Waste for Improved Solid Waste Management in Nandi County, Kenya
(African Journal of Education Science and Technology (AJEST, 2025-05)Due to rapid population growth and urbanization Nandi County is experiencing challenges of managing urban solid waste especially as this is an economic commodity that may not be optimally allocated through the normal market ... -
Influence of pH Variation on Lead Uptake and Accumulation in Raphanus raphanistrum and Brassica napus Grown in Spiked and Limed Agricultural Soils of Moiben Sub-County, Kenya
(Journal of Aquatic and Terrestrial Ecosystems, 2025-08)This study assessed Pb uptake and distribution in Raphanus raphanistrum (RR) and Brassica napus (BN) grown in agricultural soils from Moiben Sub-County, Kenya, under three soil treatments: Pb-spiked soil (to ≈1000 mg/kg), ... -
Assessing Status of Agroecological Biodiversity in Smallholder farming: Evidence from FAO TAPE Tool Localization in Busia County, Kenya
(Journal of Crops, Livestock and Pests Management, 2025-08)Agroecological biodiversity is the variety and variability of above ground organisms, that is crops, livestock, trees, and activities considered under agricultural systems. This study investigated the extent of above ... -
EFFICIENCY OF ARBUSCULAR MYCORRHIZAL FUNGI IN ENHANCING PHOSPHORUS AND COPPER UTILIZATION IN WHEAT GROWN IN FERRALSOLS OF UASIN GISHU COUNTY, KENYA
(University of Eldoret, 2025)Declining soil fertility characterized by deficiency of both macro and micronutrients is a major challenge to sustainable wheat production. Integrating bio-stimulants such as Arbuscular Mycorrhizal Fungi (AMF) with ... -
Spatial–Temporal Influence of Sand Dams on Chemical and Microbial Properties of Water from Scooping Holes in Degraded Semi-Arid Regions
(Water, 2023-09)Communities in semi-arid lands use sand dams to enhance access water during the dry seasons. However, there is limited information on the quality of water derived from these sand dams, especially in degraded lands where ... -
A Review on Challenges and Opportunities in Management of Soils of Arid and Semi-Arid Regions of Kenya
(East African Journal of Environment and Natural Resources, 2022)Arid and semi-arid lands occupy currently 88% of arable land mass in Kenya, a region with significant diversity of production systems and economic opportunities. However, these areas are characterised by low and erratic ... -
Drivers of Gully Erosion and its Socio- economic and Environmental Effects in a Tropical Semi-arid Environment
(Asian Journal of Soil Science and Plant Nutrition, 2024-03)Gully erosion is a form of severe land degradation, which is more pronounced in semi-arid and arid environments due to their vulnerable ecosystems. Establishing the causes and effects of gully erosion is therefore ... -
Enhancing Sorghum Productivity in Acidic Soils Through Lime– Fertilizer Synergism: Agronomic, Economic, and Composite Performance Analysis
