Gender aspect in adoption of commercial poultry production among peri-urban farmers in Kericho Municipality, Kenya
(Academic Journals, 2011-07-30)The main objective of this study was to assess the extent of gender effects on adoption of intensive commercial poultry production system by peri-urban farmers. The sample frame was divided into two strata made up of ... -
A Gendered Analysis of Perceived Risks of Commercial Oriented Smallholder Vegetable Farmers in Kilifi County, Kenya
(Journal of Economics and Sustainable Development, 2019)This paper examines the relationship between gender and perceived risks of commercial oriented smallholder farmers in Kilifi County. A sample of 332 smallholder vegetable farmers was selected from the study area. A 5- point ... -
Generation Means Analysis for Estimation of Genetic Parameters for Striga hermonthica Resistance in Maize (Zea mays L.)
(Canadian Center of Science and Education, 2015-08-01)Striga hermonthica is a parasitic weed species that causes considerable yield loss in susceptible maize cultivars in western Kenya. A generation means analysis was conducted to estimate gene effects influencing resista ... -
Genetic and non-genetic factors influencing KLH binding natural antibodies and specific antibody response to Newcastle disease in Kenyan chicken populations
(Wiley Online Library, 2023)This study aimed at investigating the influence of genetic and non-genetic factors on immune traits to inform on possibilities of genetic improvement of disease resistance traits in local chicken of Kenya. Immune traits ... -
Genetic and non-genetic sources of variation in natural antibodies titre values among indigenous chicken
(American Journal of Research Communication, 2017)Innate immunity plays significant role in combating disease. Improvement of any trait including resistance to disease and infection requires identification of genetic and nongenetic sources of variation. This study aimed ... -
Genetic and nutrition development of indigenous chicken in Africa
(2015)This review gives insights into genetic and feeding regime development for indigenous chicken genetic resources. We highlight and combine confirming evidence of genetic diversity and variability using morphological and ... -
Genetic and phenotypic parameters for feed efficiency in indigenous chicken in Kenya
(Elsevier, 2018-01-01)This study aims to determine the genetic and phenotypic parameters of net feed efficiency (NFE) traits namely Residual feed intake (RFI), residual gain (RG), and residual intake and gain (RIG) along the growth curve of ... -

Genetic association of agronomic traits with partial resistance to gray leaf spot in elite maize germplasm.
(John Wiley & Sons, 2022)Studies on gray leaf spot (GLS) of maize have reported inconsistencies in the relationship between partial disease resistance and agronomic traits. Understanding this variation could facilitate the use of agronomic traits ... -
Genetic differentiation of Artemia franciscana (Kellogg, 1906) in Kenyan coastal saltworks
(Gent University, Belgium, 2013)The nature of genetic divergence between the Artemia population native to San Francisco Bay, (SFB) USA and those from the introductions of SFB material in the Kenyan coast (Fundisha and Kensalt) 2 decades ago were ... -
