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 ... -
Findings from a survey in Western Kenya to determine the soil fertility replenishment technologies adoption rates
(International Journal of Agronomy and Agricultural Research (IJAAR), 2019)A survey on adoption levels of the existing soil nitrogen replenishing technologies amongst farmers in three counties in western Kenya was carried out in June 2011. Three farmer associations were Angurai Farmers Development ... -
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 ... -
The Role of Sorghum Legume Intercroping System in Improving Soil Productivity on Small Holder Farmers in Western Kenya
(International Journal of Research and Innovation in Social Science (IJRISS), 2022)Declining crops yield in the smallholder farmers cropping systems of sub-Saharan African (SSA) present the need to develop more sustainable production systems. Depletion of essential plant nutrients from the soils have ... -
Improving Soil Fertility and Crops Yields through Organic and inorganic inputs in Smallholder Farmers’ fields in Western Kenya
(International Journal of Research and Innovation in Social Science (IJRISS, 2022)Organic (FYM) and inorganic (Mavuno) manure and their combination were evaluated on sorghum grain yields and some soil chemical characteristics in the 2016 SR and 2017 LR growing seasons FYM, Mavuno and or their ... -
Effects of Source and Rates of Potassium Fertilizer on Yield Traits and Potassium Use Efficiency of Potato in a Kenyan Ferralsol
(Asian Journal of Soil Science and Plant Nutrition, 2023-09)Aims: Potassium (K) is one of the nutrient elements taken up in large amounts by potatoes, yet there is little research output on K fertilization of the crop in Kenya, due to the assumption that its natural soil reserves ... -
Ultra‑Trace Analysis of Fallout Plutonium Isotopes in Soil: Emerging Trends and Future Perspectives
(Chemistry Africa, 2023)The measurement of isotopic abundances and ratio variations of plutonium can provide important information about the sources and behaviours of radiogenic isotopes in the environment. The detection of ultra-trace isotopes ... -
Spatial Prediction and Mapping of Gully Erosion Susceptibility Using Machine Learning Techniques in a Degraded Semi-Arid Region of Kenya
(Land, 2023)This study aimed at (i) developing, evaluating and comparing the performance of support vector machines (SVM), boosted regression trees (BRT), random forest (RF) and logistic regression (LR) models in mapping gully erosion ... -
Effect of land rehabilitation measures on soil organic carbon fractions in semi-arid environment
(Frontiers in Sustainable Food Systems, 2023-02)Soil erosion threatens the sustainable intensification of food systems among smallholder farmers in arid and semi-arid lands (ASALs). Intensifying adoption of soil mitigation and rehabilitation measures is thus needed ... -
