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 ... -
Genotype variant of soybean cultivars around Lake Victoria region, East Africa
(2010-01)Glycine gracilis, which originated from North-East China, is morphologically intermediate between the cultivated G. max and the wild form, G. soja. These three forms are cross-compatible and their crosses provide a resource ... -
Introgression of Stem Rust Resistance into Popular Kenyan Wheat Varieties to Improve Production
(2018-02)Aim: The objective of this study was to assess the introgression of the stem rust resistance genes into the BC1F1 plants using molecular markers. Place and Duration of Study: Field experiments were carried out in a ... -
Inter-seasonal Effects on Selected Maturity Parameters of DK8031 Maize Grown under Varying Irrigation and Nitrogen Levels in Embu County, Kenya
(2017-07)Maize is a staple food and a source of carbohydrates to a large proportion of people in Kenya. The performance of crop plants such as maize depends on a number of factors such as climate, soil characteristics and plant ... -

(2017-06)Aims: This study was conducted to determine the agronomic performance of respective maize single crosses in different environments in varying soil and climatic zones in Kenya. Methodology: The trials were conducted at ... -
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 ... -
Planting Pits’ Effects on Soil Nutrients in a Sorghum and Pigeon Pea Rotation in Semi-arid Areas of Eastern Kenya
(Science Domain International, 2016-12)Planting pits are rain water harvesting structures that trap water and nutrients in surface runoff and rain water falling directly into the pits. Planting pits have been promoted for improving crop yields without considering ... -
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 ... -
Coping Strategies against Climate Change in Agricultural Production in Kitui District, Kenya
(World Science and Research Publishing, 2014-10)The aim of this paper is to assess the coping and adaptation strategies that have been employed by farmers in their agricultural activities against the effects of climate change in Kitui district. It also looks at the ... -
Effect of Climate Change on Small Scale Agricultural Production and Food Security in Kitui District, Kenya
(World Science and Research Publishing, 2014-10)Most of the world’s arid and semi-arid lands (ASALs) are found in the developing countries. These ASALs face many challenges some of which are as a result of the declining availability of water resources and increasing ... -
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 ... -
Inoculated Soybean Yields Response to Nitrogen and Phosphorus Application
(SCIENCEDOMAIN international, 2016)Inherent low soil nitrogen (N) and phosphorus (P) is one of the major hindrances of increased soybean productivity in Malawian soils. Although, inoculation of legumes with rhizobia, has been advocated for decades as a ... -
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 ... -

Tracking the Expression of Photosensitive Genic Male Sterility Gene in Rice
(2013-09)Photoperiod sensitive genic male sterile rice lines contain genes that induce complete male sterility in high temperature and long day light length period, but are male fertile under low temperature ... -
Potential of Bio-/Agro-Terrorism in Kenya
(2015-08)The growing Biotechnology and Bio-Engineering may have by commensurate measure contributed to bio-terrorism. This has led to stringent measures to deal with it especially, in developed economies like the ... -
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 ... -
