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 ... -
Combining measurements, modeling and machine learning to improve N2O accounting for sustainable agricultural development in sub-Saharan Africa
(Swiss Data Science Center, 2023-06)Sub-Saharan Africa continues to grapple with food insecurity due to low crop yields. While an increase in synthetic fertilisers could potentially increase agricultural productivity in the region, it would lead to an ... -
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 ... -
EFFECTIVENESS OF PROMISING COMMERCIAL BIOFERTILIZERS ON SOYBEAN PRODUCTION IN BUNGOMA COUNTY, WESTERN KENYA.
(University of Eldoret, 2013)The study was conducted to compare the performance of promising commercial bio-fertilizers that have been evaluated under the green-house conditions at TSBF-CIAT, in farmers’ conditions through the use of promiscuous soybean ... -
EVALUATION OF NITROGEN FERTILIZER, LIME AND SOIL-WATER EFFECTS ON THE YIELD AND MALTING QUALITIES OF BARLEY (Hordeum vulgare L.)
(University of Eldoret, 2013)Barley (Hordeum vulgare L.) is a cereal crop that grows over a wide range of environments and in Kenya it is grown primarily for malting. Barley requires adequate nitrogen (N) for good grain yields and quality malting, ... -
EFFECT OF HARVESTING METHODS AND NPK FERTILIZER ON SOIL pH, SOIL AND LEAF MAJOR NUTRIENTS CONTENTS AND YIELD OF TEA IN TANZANIA
(University of Eldoret, 2015)Tea (Camellia sinensis, (L), O. Kuntze crop in Tanzania has been traditionally harvested by hand. In recent years, high cost and shortage of labour have compelled tea growers to opt for mechanical harvesting. Mechanical ... -
WHEAT RESPONSE TO PHOSPHORUS FERTILIZERS AND AGRICULTURAL LIME IN UASIN GISHU COUNTY, KENYA.
(University of Eldoret, 2016)When water is not limiting, soil acidity, deficiencies of phosphorus (P) and nitrogen (N) amongst others are considered to be the major causes of low wheat yields in Uasin-Gishu County, Kenya. In this County, average annual ... -
Effect of soil amendments on availability of soil phosphorus and uptake by maize in Vihiga County, western Kenya
(African Journal of Rural Development, 2018)The combined use of organic inputs and fertilizers as promoted via Integrated Soil Fertility Management (ISFM) approach may have a significant effect on bioavailability of phosphorus (P) and enhance its uptake by crops. ... -
