Enhancing legume crop pollination and natural pest regulation for improved food security in changing African landscapes
(Elsevier, 2020-09)Legumes are important crops for food security, consumed by millions of people especially in Africa where they are an essential protein source and provide key vitamins and minerals. Most legumes depend on insect pollination ... -
Evaluation of Leucaena leucocephala as a source of N for maize
(1997-01)Prunings of leucaena [Leucaena leucocephala (Lam.) De Wit] have long been regarded as a useful alternative to N fertilizer, but N use efficiency by crops is often low. The potential exists to synchronise nutrient ... -
Evaluation of photoperiod and thermosensitive genic male sterile lines for hybrid rice seeds production in Kenya
(2013)Photo–thermo-sensitive genic male sterile (P(T)GMS) rice is a new hybrid rice technology that uses prolonged light length and high temperatures to induce sterility. This technology is being introduced in Kenya but such ... -
Evaluation of the effect of ripening on the sensory quality and properties of tamarillo (Cyphomandra betaceae) fruits
(Elsevier, 2007-03-31)Tamarillo (Cyphomandra betaceae) fruits were sourced from a single farmer from the Central province of Kenya soon after harvesting. The fruits were then cleaned and sorted in order to remove all immature and damaged fruits. ... -
Exploring the Changes of Resistant Genes Expression in Groundnuts (Arachis Hypogea) In Response to Aspergillus Flavus Exposure at Seedling Stage
(2020-07)Aspergillus flavus infect groundnut seeds and produce secondary metabolites, aflatoxins. The aflatoxins are associated with various diseases in domestic animals and humans globally. Mitigating the aflatoxin contamination ... -
Farming systems’ typologies analysis to inform agricultural greenhouse gas emissions potential from smallholder rain-fed farms in Kenya
(Elsevier B.V, 2020)Most sub-Saharan Africa smallholder farming systems are highly heterogeneous. Direct quantification of greenhouse gas emissions from these farming systems is hampered by di- versity at farm-level. Each farm contributes ... -
Flower visitors of Streptocarpus teitensis: implications for conservation of a critically endangered African violet species in Kenya
(PeerJ, 2021-01)Background: The African violets are endangered plant species restricted mainly to the Eastern Arc Mountains biodiversity hotspots in Kenya and Tanzania. These plants grow well in shaded environments with high humidity. ... -

(UoEm, 2023-11-11)Pine Bluff Junior High School recently displayed its garden during a visit by Karleah Harris, assistant professor for the Department of Human Sciences at the University of Arkansas at Pine Bluff, along with UAPB alumni and ... -
Genetic Characterization of Arabusta Coffee Hybrids and their Parental Genotypes using Molecular Markers
(2015)Twenty coffee genotypes were characterized comprising of eleven F1 interspecific Arabusta hybrids, three induced tetraploid Robusta parental genotypes, four Arabica parental genotypes, one diploid Robusta accession and ... -
Genetic Diversity of Cassava Mutants, Hybrids and Landraces Using Simple Sequence Repeat Markers
(SCIENCEDOMAIN international, 2014-10-11)Aims: Cassava (Manihot esculenta Crantz) is a crop with largely unexplored and unexplained potentially valuable genetic variability. The knowledge and understanding of the extent of genetic variation of cassava germplasm ... -
Genetic diversity of determinate French beans grown in Kenya based on morpho-agronomic and simple sequence repeat variation
(Academic Journals, 2015-08)French bean (Phaseolus vulgaris L.) in Kenya is cultivated predominantly in the Central, Eastern and Rift Valley provinces. Despite its importance as an export commodity, there has been little breeding effort devoted to ... -
Genetic diversity of Faidherbia albida (Del.) A. Chev accessions held at the World Agroforestry Centre
(Taylor & Francis, 2015-06)This study assessed the extent and distribution of genetic diversity of 29 Faidherbia albida provenances from 10 African countries by employing amplified fragment length polymorphism with an aim of providing crucial ... -
Genetic variability analysis for growth and yield parameters in double cross maize (Zea mays l.) genotypes in Kitale county of Kenya
(Science Journals Publishing, 2013)Present study was conducted to select hybrids with improved yield, to identify testers for grain yield and to determine the magnitude of genetic variability in maize hybrids for yield and its elements. Adaptability of ... -
