(Elsevier, 2015-11)Climate variability has a negative impact on crop productivity and has had an effect on many small-holder farmers in the arid and semi-arid lands (ASALs). Small-holder farmers in Eastern Kenya are faced with the constraint ... -
Performance Evaluation of Proximal Sensors for Soil Assessment in Smallholder Farms in Embu County, Kenya
(MDPI, 2016)Four proximal soil sensors were tested at four smallholder farms in Embu County, Kenya: a portable X-ray fluorescence sensor (PXRF), a mobile phone application for soil color determination by photography, a dual-depth ... -
Leveraging on germplasm acquisition for Arabica coffee improvement in Kenya
(Scienceweb Publishing, 2016-01)The low genetic variability within Coffea arabica species is a major hindrance to its improvement. The emergence of new pathogen races, especially for the prevalent fungus Hemileia vastatrix ... -
Proximity to Woodland and Landscape Structure Drives Pollinator Visitation in Apple Orchard Ecosystem
(Crossmark, 2016-04)Landscapes of farms and adjacent areas are known to influence abundance of various arthropods such as pollinators in commercial agricultural ecosystems. In this context, we examined the effect of heterogeneous landscapes ... -
Genotype X Environment Interaction of Inbred Lines of Maize (Zea Mays L.) and Stability of Crosses in Kiambu and Embu Counties, Kenya.
(2016-05)Despite the fact that virtually all households in Kenya grow maize over 60% of them are net maize buyers because they do not produce enough for their consumption. Kenya’s current food supply situation and outlook give ... -
Pollination Ecology of Desmodium Setigerum (Fabaceae) in Uganda; Do Big Bees Do It Better?
(2016-08)Explosive pollen release is documented in many plant families, including the Fabaceae. Desmodium setigerum E. Mey (Fabaceae) is a perennial herb with single trip explosive pollen release found in eastern Africa, and the ... -
Combining Ability of Inbred Lines of Maize (Zea mays) in Kiambu and Embu Counties, Kenya
(Science Domain International, 2016-08)Despite the fact that virtually all households in Kenya grow maize, over 60% of them are net maize buyers because they do not produce enough for their consumption. This is due to both biotic and abiotic factors such as ... -
A global synthesis of the effects of diversified farming systems on arthropod diversity within fields and across agricultural landscapes. Global Change Biology
(Wiley Online Library, 2017-03)Agricultural intensification is a leading cause of global biodiversity loss, which can reduce the provisioning of ecosystem services in managed ecosystems. Organic farming and plant diversification are farm management ... -
Determination of Post Striga Attachment Resistance in Selected Resistant Sorghum Lines in Kenya
(International Knowledge Press, 2017-05)Breeding for Striga resistance in sorghum and other cereals is recognized as the most sustainable control measure, however there is a lack of cereal germplasm that exhibit post attachment to Striga that limits this ... -
Physiological and Agronomic Performance of Domesticated and Wild Cotton Germplasm from Selected Regions of Kenya
(2017-05)making cooking oil, soup and seed cake for animal feed industry among other uses. Performance of wild cotton germplasm in Kenya has not been well studied and therefore there is need for understanding the correlation of ... -
Determination of Stem Rust Ug99 Disease Severity in Selected Wheat Backcrosses in Kenya
(2017-05)Stem rust (Puccinia graminis tritici) is a disease of economic importance in wheat (Triticum aestivum L.) worldwide. The objective of this study was to determine the disease severity of the BC1F1 plants in the nursery at ... -
Pathogenicity of Colletotrichumkahawae in Kenya
(2017-05)This study was aimed at determining the virulence diversity of Colletotrichumkahawae, and their correlation with coffee growing regions and interaction with coffee varieties in Kenya. A total of 34 single conidia isolates ... -
