Genetic Diversity of Phaeoisariopsis griseola in Kenya as Revealed by AFLP and Group-specific Primers
(2004)
Genetic diversity of 50 Phaeoisariopsis griseola isolates collected from different agroecological zones in Kenya was studied using group-specific primers and amplified fragment length polymorphism (AFLP) markers. Group-specific ...
An analysis of factors affecting smallholder mixed farming activities, performance and interactions in Wundanyi location, Taita district, Kenya
(2010)
Principal component analysis was used to analyze data collected from a dynamic study of thirty mixed dairy-crop farmers. The study was undertaken for II months over two rainy seasons to analyze the major production factors ...
Reaction of selected common bean genotypes to physiological races
(2011)
The wide pathogenic variability occurring in Phaeoisariopsis griseola, the causal agent of angular leaf spot of common bean (Phaseolus vulgaris L.), dictates that new sources of resistance be continuously identified. This ...
Occurrence of Root Rot Disease of Common Bean (Phaseolus vulgaris L.) In Association with Bean Stem Maggot (Ophyiomia sp.) In EMBU District, Kenya
(Asian Network for Scientific Information, 2007)
Two surveys were carried out in October 2001 (season 1) and April 2002 (season 2) in five divisions of Embu district during the short and long rains, respectively. Ten farms were randomly selected per division and fifteen ...
Reaction of potato c~lt!vars ,to ralston!~ solana cearumin Kenya
(2001)
A survey of bactenal wilt (BW) incidence was carried out in three potato producing districts of Kenya, namely, Nyeri, Nyandarua, and Meru in 1997. The survey was carried out in 30 randomly selected farms in each district. ...
Evaluation of host-pathogen interaction of Mycovellosiella' Cajan with pigeonpea
(2003)
Although Mycovellosiella cajan is an important pathogen limiting production of pigeon pea through transmission of Mycovellosiella leafspot, little is known about the structural formation of either the host (pigeonpea) or ...
The challenges of rehabilitating denuded patches of a semi-arid environment in Kenya
(2010)
Land degradation is a major problem in the semi-arid environments of Sub-Saharan Africa. Fighting land degradation is essential to ensure the sustainable and long-term productivity of the habited semiarid lands. In Kenya, ...
The role of varietal traits in the adoption of improved dryland crop varieties: The case of pigeon pea in Kenya
(2011-09)
This study uses a multivariate probit model and the Poisson regression to examine the role of
varietal attributes in farmers’ adoption of improved pigeon pea (Cajanus cajan) varieties in
Taita District, Kenya. It is based ...
Effect of intercropping maize with different bean genotypes on the incidence and severity of flourly leaf spot disease and yield of beans
(2000)
A study was undertaken to characterise the virulence variability in Phaeoisariopsis griseola, the causal agent of angular leaf spot of common bean (Phaseolus vUlgaris l.) and to determine the physiological races of the ...
Distribution of lesion nematodes associated with maize in Kenya and susceptibility of maize cultivars to pratylenchus zeae
(1998)
The distribution and impact of lesion nematodes (Pratylenchus spp.) in Kenyan maize producing areas were evaluated. Soil and root samples were taken from 120 farms in three districts of Kenya, namely Kakamega, Machakos and ...
