ASSESSMENT OF ADVANCED COMMON BEAN (Phaseolus vulgaris L.) LINES FOR NUTRIENT UPTAKE, PHOSPHORUS EFFICIENCY AND YIELD IN LOW PHOSPHORUS SOIL TYPES OF KAKAMEGA COUNTY
(University of Eldoret, 2013)Common bean (Phaseolus vulgaris L.) is an important source of food protein and cash in Kakamega County. Production is constrained by soil phosphorus which is mainly due to low phosphorus content of soils, export of phosphorus ... -
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 ... -
DEEP TILLAGE, LIME, MICRONUTRIENTS AND ORGANIC INPUTS REHABILITATE POORLY RESPONSIVE SOILS IN SMALLHOLDER MAIZE (Zea mays) AND SOYBEAN (Glycine max) CROPPING SYSTEMS OF WESTERN KENYA
(2018)Maize (Zea mays) and soybean [Glycine max (L.) Merr] grain yields in smallholder farms of western Kenya are persistently low, particularly in soils that respond poorly to fertilizer application. A multi-locational trial ... -
DESMODIUM EFFECT ON SOIL FERTILITY, STRIGA CONTROL AND MAIZE PRODUCTION IN BUSIA AND SIAYA COUNTIES, WESTERN KENYA.
(University of Eldoret, 2013)Low soil fertility, stemborer and Striga weeds limit production of maize in western Kenya. Desmodium in the “Push-Pull” technology has been found to reduce Striga and stemborer but its contribution to soil fertility ... -
DEVELOPMENT OF SOIL CLIMATE REGIMES OF KENYA USING SPATIAL JAVA NEWHALL SIMULATION MODEL
(2016-05-23)Climate change is a fundamental threat to food security, development and the fight against poverty. Identification of strategies to alleviate its impacts on agriculture is essential. One such strategy is making future ... -
EFFECT OF CONSERVATION AGRICULTURE ON SELECTED SOIL PROPERTIES, MAIZE AND BEANS PERFORMANCE IN WESTERN KENYA AND EASTERN UGANDA
(2015)Despite Conservation Agriculture (CA) being advantageous towards improving soil quality and thus productivity, farmers in Western Kenya and Eastern Uganda still practice conventional tillage (CT). These result into soil ... -
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 ... -
Effect of Irrigation with Waste Water on Soil Characteristics and Bean Yield: A Case Study of University of Eldoret Farm
(AER Journal, 2019)Experimental field treatments were set up at the University of Eldoret farm that is next to the wastewater treatment plant. The farm is located in Uasin Gishu County, Kenyan North Rift part. The field experiments were ... -
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 ... -
EFFECT OF PHOSPHATE FERTILIZER ON GROWTH AND YIELD OF COWPEA (Vigna unguiculata) IN NANDI SOUTH
(2018)Phosphorus deficiency remains a key constraint to cowpea productivity in Kenya. In addition, there exist conflicting results about the effect of leaf harvest on cowpea yield. Therefore, an on-farm and greenhouse study was ... -

(University of Eldoret, 2018)Phosphorus deficiency remains a key constraint to cowpea productivity in Kenya. In addition, there exist conflicting results about the effect of leaf harvest on cowpea yield. Therefore, an on-farm and greenhouse study was ... -
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. ... -
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 LIMING MATERIALS AND PHOSPHORUS FERTILIZER APPLICATION ON MAIZE PRODUCTION IN ACID SOILS OF SIAYA AND KAKAMEGA COUNTIES.
(University of Eldoret, 2013)Soil acidity is a major contributor to soil infertility in western Kenya. Smallholder farmers in this region have persistently realized low yields (< 1 t ha-1 season-1 maize) in comparison to potential estimates of 6 – 8 ... -
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 ... -
EFFECTS OF CROPPING SYSTEMS, NUTRIENT LEVELS AND CROP RESIDUE APPLICATION ON SOIL ORGANIC CARBON CONTENT UNDER MINIMUM TILLAGE EXPERIMENT IN TESO DISTRICT, KENYA
(University of Eldoret, 2013)Minimum tillage practice and the use of cropping systems that maximize crop residue addition to the soil have been efficient agricultural practices in maintaining or increasing soil organic carbon (SOC) which, though central ... -
EFFECTS OF LIME AND INORGANIC FERTILIZERS ON MAIZE YIELD AND STRIGA (Striga hermonthica) GROWTH IN ACID SOILS OF KAKAMEGA AND SIAYA COUNTIES, KENYA
(University of Eldoret, 2015)Food insecurity is one of the major challenges in sub-Saharan Africa (SSA), Kenya included, and continues to pose a threat to the existence of millions of the inhabitants of the region. Yet a lot of research has been carried ... -
EFFECTS OF NITROGEN FERTILIZER AND HERBICIDE COATED MAIZE
