Decomposition of Cassia siamea loppings in semiarid Machakos, Kenya
(1994)The rate of decomposition of Cassia siamea Lam. prunings in an alley cropping system was investigated using litter bags in the semiarid area of the Machakos District, Kenya, during the short rains of 1988 and the long rains ... -
Demarcating day-light-length from temperature effects in PGMS rice using back tracking method.
(2014)Two near isogenic rice lines ZAU11S106 (Photoperiod sensitive genic male sterile) and ZAU11F121(a ZAU11S106 whose PGMS gene has undergone reverse mutation to become a non-PGMS) were used. These two lines were studied to ... -
Determinants for rainwater harvesting adoption: a case study of smallholder farmers in Murang’a County, Kenya
(UoEm, 2024-05-17)Rainwater harvesting has been practiced among smallholder farmers for centuries in many parts of the world. Recently, it has gained more attention due to the reported increasing water demand and the need for sustainable ... -
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 ... -
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 ... -
Development of a Water Quality Assessment Index for the Chania River, Kenya
(Taylor and Francis, 2020-11)Human-related activities are known to have deleterious effects on the water quality of aquatic ecosystems, but there is limited information on the impact of these on rivers in tropical regions, such as the Chania River ... -

Diallel analysis of Snap bean (Phaseolus vulgaris l.) varieties for important traits
(Academic Journals, 2010-08-04)The breeding programmes of many crops use diallel analyses because of the genetic information they offer to breeders. Six morphological and agronomic traits of Snap bean (Phaseolus vulgaris L.) were studied to investigate ... -
A Diallel Cross-Based Analysis of the Genetic Basis of Pod Quality and Pod Yield in Snap Bean
(UoEm, 2024-07-27)Snap bean (Phaseolus vulgaris L.) is among the leading vegetables in Kenya that is mainly grown for export with the potential to increase household income. There are few programs in Kenya that focus on breeding new ... -
Dissemination of Integrated Soil Fertility Management Technologies Using Participatory Approaches in the Central Highlands of Kenya
(Springer Netherlands, 2011-06)Declining soil fertility and productivity is a critical problem facing smallholder farmers in the central highlands of Kenya. A study to improve soil fertility and farm productivity within the smallholder farming systems ... -
Diversity analysis and genome‑wide association studies of seed weight trait in Bambara groundnut (Vigna subterranea (L.) Verdc.) using diversity array technology sequence derived single nucleotide polymorphism markers
(UoEm, 2025-02-22)Bambara groundnut is an indigenous drought tolerant legume cultivated in Africa. In Kenya, the crop is grown by women and the diver- sity of the accessions grown is unknown. Lack of information on the crop’s diversity ... -
The diversity of rural livelihoods and their influence on soil fertility in agricultural systems of East Africa – A typology of smallholder farms
(2010)Technological interventions to address the problem of poor productivity of smallholder agricultural systems must be designed to target socially diverse and spatially heterogeneous farms and farming systems. This paper ... -
Drought and heat tolerance in coffee: a review
(International Research Journals, 2012-12)Climatic variability is the main factor responsible for the fluctuations in the coffee yield in the world. The relationships between the climatic parameters and the agricultural production are quite complex, because ... -
The drying kinetics of kale (Brassica oleracea) in a convective hot air dryer
(Elsevier, 2005-12-31)The effect of air temperature and sample thickness on the drying kinetics of kale was investigated using a convective air dryer at a fixed airflow rate of 1 m/s and drying air temperatures of 30, 40, 50 and 60 °C. The ... -
The drying of onion slices in two types of hot-air convective dryers
(Academic Journals, 2012-08-07)Drying experiments were carried out using two types of convective hot-air dryers such that the hot air passed perpendicularly through a thin layer of onion slices in one dryer while the air passed parallel to the thin layer ... -
Early Agronomic Performance of Some New and Existing Arabica Coffee Varieties in Kenya
(2015)The primary goal of plant breeding is to improve yield, quality and disease resistance. However, majority of reported work on coffee breeding primarily concerns agronomical improvement that directly impinges on either ... -
Effect of Bt cotton expressing Cry1Ac and Cry2Ab2 protein on soil nematode community assemblages in Mwea, Kenya
(2013)Objective: The nematode community structure in soil cultivated with Bt cotton (containing Cry1Ac and Cry2Ab2 protein), isoline (non Bt cotton) and HART 89M (non Bt cotton) was evaluated in a field trial at Ndomba in 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 ... -
Effect of decomposition intensity of incorporated chickpea manure on stability and saturated hydraulic conductivity of a clay loam and clay soil
(Academic Journals, 2011-03-04)The role of organic matter (OM) in soil aggregation and saturated hydraulic conductivity (Ksat) has long been recognised but their depedence on the intensity of decay is less studied. The objective of this study was to ... -
