(University of Eldoret, 2025)Lack of accurate and precise diagnostic tools and methods for detecting soil pathogens and their impacts on crop yields hinders the productivity of various crops, including beans. This highlights the need to link field ... -
EVALUATION OF IMPACTS OF INTEGRATED LIME AND FERTILIZER APPLICATION ON SELECTED SOIL CHEMICAL PROPERTIES AND SORGHUM PRODUCTIVITY IN ACID SOILS OF WESTERN KENYA
(University of Eldoret, 2025)This research assessed sustainable strategies aimed at enhancing soil fertility and sorghum production in the acidic soils of western Kenya. Microdosing trials were carried out in Kakamega and Siaya. These were executed ... -
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 ... -
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 ... -
POTATO (Solanum tuberosum L.) TUBER YIELD AND QUALITY AS INFLUENCED BY POTASSIUM FERTILIZER IN UASIN GISHU COUNTY, KENYA
(University of Eldoret, 2024)Irish potato is the second most important food crop after maize in Kenya. However, the national average tuber yield is 9.8 tonnes ha-1 which is low compared to optimum production of 41 tonnes ha-1 . There is unmet ... -
ENHANCING SOIL NITROGEN THROUGH CROP ARRANGEMENTS AND FERTILIZER: A COMPARATIVE ANALYSIS OF MBILI INTERCROPPING AND CONVENTIONAL METHODS FOR SUSTAINABLE MAIZE- SOY BEAN FARMING IN WESTERN KENYA
(University of Eldoret, 2024)Low fertility in highly weathered and degraded soils largely accounts for low and unsustainable crop yields in most African countries. Nitrogen (N) is the most deficient among other nutrients because other than being ... -
FINGER MILLET (Eleusine coracana) AND SOYBEAN (Glycine max) RESPONSES TO NPK FERTILIZER IN ZINC-AMENDED SOILS OF WESTERN KENYA
(University of Eldoret, 2024)Low agricultural productivity in SSA is attributed primarily to declining soil fertility. About 65% of the agricultural soils in SSA are degraded as a result of nutrient depletion without adequate replenishment. Under ... -
TERRACE ADOPTION AND ITS ROLE IN SOIL ORGANIC CARBON DYNAMICS IN AGROPASTORAL WESTPOKOT COUNTY, KENYA
(University of Eldoret, 2024)Drylands of West Pokot experience severe soil erosion that has affected the community’s livelihood and socio-economic dynamics. The severity of erosion in the region is sustained by vulnerable soils and human activities ... -
INFLUENCE OF FERTILIZER TYPES AND INTERCROPPING ON SOIL CHEMICAL PROPERTIES AND CROP PERFORMANCE IN SELECTED PARTS OF BUSIA COUNTY WESTERN KENYA
(University of Eldoret, 2024)In order to address the low soil fertility and low crop yields within Busia county of western Kenya, an integrated soil fertility study was carried out during the 2016 SR and 2017 LR at Busia ATC and Teso farmers field ... -
EFFECT OF SOIL AMENDMENTS ON THE PERFORMANCE OF SELECTED AFRICAN INDIGENOUS VEGETABLES IN UASIN GISHU AND TRANS NZOIA COUNTIES
(University of Eldoret, 2016)African Indigenous Vegetables (AIVs) have high nutritive value, require less inputs and can be a reliable source of income to resource challenged families. However, their production in western Kenya is hampered by limited ... -
