Agronomic biofortification of maize and beans in Kenya through selenium fertilization
(Springer Netherlands, 2019)Deficiency in calcium, zinc, selenium, and iodine remains a major health issue in Africa. A selenium (Se) status survey conducted in central Kenya highlands revealed a high risk of dietary Se deficiency. This study ... -
Development of a Non-Mist Vegetative Propagation Protocol for Eucalyptus Hybrid Clones
(Journal of East African Natural Resources Management, 2009)Eucalyptus trees have proved to be a popular species for farm forestry,however their vegetative propagation has not been optimised mainly due to the high cost of infrastructure used to propagate them in mist ... -
Interaction of Phaseolus vulgaris with thermotolerant isolates of Rhizobium leguminosarum biovarphaseoli from Kenyan soils Interaction dePhaseolus vulgaris avec des isolats thermo-tolérants deRhizobium leguminosarum biovarPhaseoli de sols du Kenya
(Kluwer Academic Publishers, 1989)Thermotolerant strains of Rhizobium leguminosarum biovarphaseoli were isolated from nodules of Phaseolus vulgaris grown in Kenyan soils, where high soil temperatures often exceed 40°C during sunny days. The isolates varied ... -
Biological nitrogen fixation in selected legumes of the semi-arid Makueni District of Southeast Kenya
(Der Tropenlandwirt-Journal of Agriculture in the Tropics and Subtropics, 1999)The major objective of this study was to investigate biological nitrogen fixation in two main legumes (green gram and common bean) grown in semi-arid southeast Kenya. Nodulation experiments on the two legumes were carried ... -
Studies on the Ecophysiology of Locally Suitable Cultivars of Food Crops and Soil Fertility Monitoring in the Semi-arid Areas of Southeast Kenya: A Final Report on a Collaborative Research Project Between Kenyatta University, Nairobi/Kenya, and the University of Trier, Germany
(Geographische Gesellschaft Trier, 2000) -
Nitrogen fixation by common bean (Phaseolus vulgaris L.) in pure and mixed stands in semi-arid south-east Kenya
(Elsevier, 2001)Research was carried out in the field on the effect of intercropping common bean and maize crops in a semi-arid zone of south-east Kenya over two rainy seasons in 1997. The experimental design was a randomised complete ... -
Crop water relationships and thermal adaptation of Kathika beans (Phaseolus vulgaris L.) and green grams (Vigna radiata L. Wilczek) with special reference to temporal patterns of potential growth in the drylands of SE-Kenya
(Academic Press, 2001)High soil temperatures influence seedling emergence as well as the performance of plant organs and yields. Temperatures of above 40°C were recorded in the topsoil of the Ferralsols of the semi-arid areas of SE-Kenya during ... -
Population levels of indigenous bradyrhizobia nodulating promiscuous soybean in two Kenyan soils of the semi-arid and semi-humid agroecological zones
(Journal of Agriculture and Rural Development in the Tropics and Subtropics (JARTS), 2006)Soybeans grown in Africa have been selected to nodulate effectively with indigenous Bradyrhizobium spp. populations since Bradyrhizobium japonicum populations are considered absent or in very low numbers in African soils. ... -
Isolation, molecular characterization and evaluation of local isolates of bacillus thuringiensis against the larger grain borer Prostephanus Truncatus (Horn) And The Maize Weevil Sitophilus Zeamais (Motsch)

Antibiotic resistance of bacteria isolated from Nairobi River
(2006)This study aimed to evaluate the antibiotic resistance of bacteria isolated from six sites along the pollution gradient of Nairobi River. Bacteria were isolated by standard Methods and grouped into 3 categories; enteric ... -
Evaluation of nitrogen fixation using 15N dilution methods and economy of a maize-tepary bean intercrop farming system in semi-arid SE-Kenya
(Springer, Dordrecht, 2007)Tepary bean has become popular among poor small-scale farmers in semi-arid Kenya, where it is intercropped with maize. This study aimed at i) evaluating the N-economy of maize/tepary bean intercrop versus sale crop using ... -
Somatic embryogenesis and plant regeneration from immature embryos of tropical maize (Zea mays L.) inbred lines
(2008)Somatic embryogenesis and plant regeneration was achieved from immature embryos of six maize (Zea mays L.) inbred lines (CML216, CML78, CML331, TL18, TL27 and MU25). Callus was initiated on N6 medium supplemented with ... -
Biological nitrogen fixation by promiscuous soybean (Glycine max L. Merril) in the central highlands of Kenya: response to inorganic fertilizer soil amendments.
(IDOSI Publications, 2010)Biological nitrogen fixation (BNF) by promiscuous soybean cultivars offers a potential for minimizing the investment made by resource-limited farmers in central highlands of Kenya. Nitrogen fixation in this grain legume ... -
Low technology tissue culture materials for initiation and multiplication of banana plants
(African Crop Science Society (Uganda), 2010)Tissue culturing has become a routine method for propagating plants in high technology laboratories. The cost of production using conventional tissue culture is, however, high for most of the countries in the sub-Saharan ...
