IMPROVING GROUNDNUT AND MAIZE YIELDS BY ENHANCING BIOLOGICAL NITROGEN FIXATION OF FERRALSOLS AND ACRISOLS IN WESTERN KENYA
(University of Eldoret, 2014)Food insecurity in sub - Saharan Africa (SSA) is on the rise and this has become a global concern. One of the major contributing factors to this scenario is soil fertility depletion that culminates to low food productivity. ... -
INFLUENCE OF AGRICULTURAL LIME ON SOIL PROPERTIES AND WHEAT (Triticum aestivum L.) YIELD ON ACIDIC SOILS OF UASIN GISHU COUNTY, KENYA
(University of Eldoret, 2013)Soil acidity, one of the contributors to soil fertility depletion, has become a matter of concern in sub- Saharan Africa. In Kenya, 13% of the soils are acidic and are considered to be low fertility due to highly weathered ... -
Influence of farm and technology characteristics on farmers ‘perception of soil and water and water conservation technologies in west Pokot County, Kenya
(IOSR Journal of Agriculture and Veterinary Science, 2019)Soil plays significant roles in the earth’s life-support system through the provision of a multitude of essential ecosystem services to humans and the environment. But due to severity of soil erosion this ecosystem services ... -
INFLUENCE OF PHOSPHORUS FERTILIZER ON POTATO (Solanum tuberosum L.) SEED PRODUCTION IN ACID SOILS IN KENYA
(University of Eldoret, 2021)One of the major challenges facing potato (Solanum tuberosum L.) production in Kenya is the inadequate supply of high-quality seed. Of the approximated 70,000 tonnes of Kenya’s potato seed annual requirement, only 1 % is ... -
INTEGRATED WATER AND NUTRIENT MANAGEMENT IN IRRIGATED KANO PLAIN’S PADDY FIELDS, KENYA
(University of Eldoret, 2012)Water shortage and paddy field nutrient (nitrogen) depletion are major constrains to sustaining and increasing rice (Oryza sativa L.) production in Kano plains, Kenya. Scarcity of water resources and increasing cost of ... -
MAIZE-SOYBEAN PRODUCTION AND MICROBIAL DIVERSITY AS AFFECTED BY RHIZOBIA INOCULATION AND CROPPING SYSTEMS IN A FERRALSOL IN WESTERN KENYA
(2018)The use of promiscuous soybean varieties and commercial inoculants has been shown to increase production and improve soil fertility. However, most cropping systems are characterized by indigenous bradyrhizobia whose ... -
NUTRIENT DYNAMICS, ALLELOPATHY LEVELS AND CROP PERFORMANCE UNDER EUCALYPTUS GRANDIS TREES IN KENYA
(University of Eldoret, 2018)Successful Eucalyptus-crop intercropping is limited by; soil nutrients and water dynamics, allellochemical accumulation in the soil and competition for light between trees and crops among other factors. A study with the ... -
NUTRIENTS LIMITING SOYBEAN (Glycine max L) PRODUCTION IN ACRISOLS AND FERRALSOLS OF KAKAMEGA AND BUSIA COUNTIES
(2016-05-23)Soybean is a good source of protein and calories and therefore important for food security. Soybean yields in western Kenya stand at 0.6 t ha-1 season-1against a potential of 3 to 3.6 t ha-1 season-1. This has been attributed ... -
