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 ... -
Evaluating the macropropagation efficiency of banana varieties preferred by farmers in Eastern and Central Kenya
(Kenya Agricultural Research Institute, 2010)Kenyan farmers are threatened by overreliance on few crops whose yields are reduced by adverse climatic changes. Bananas are more resilient and produce year round, making it a more suitable crop. To increase banana production, ... -
Cassava production and limitation of propagation through tissue culture
(Contribution of Agricultural Sciences towards achieving the Millenium Development Goals, 2010)With the unrelenting increase in human population it is important that concerted efforts be made to increase crop productivity so as to match the expected increase in food demand. The gravity of this problem is well ... -
Nodulation and nitrogen fixation in promiscuous and non promiscuous soybean (Glycine max (L.) Merrill) varieties in Eastern Kenya
(Kenya Society of Microbiology, 2010)Soil nitrogen deficiency is a major factor limiting soybean production. This problem can be alleviated by the use of nitrogen fertilizers which on the other hand adversely affect the environment, are expensive and ... -
A low-cost medium for sweet potato micropropagation
(African Crop Science Conference Proceedings, 2011)Tissue culture has not been optimised in sweet potato (Ipomoea batatas (L) Lam) propagation due to high costs. With an aim of producing affordable disease-free seedlings, a low cost medium was developed and used to ... -
Banana distribution and their seed systems in central and eastern Kenya.
(African Crop Science Society, 2011)Bananas (Musa spp.) serve as food, income resource and animal feed in addition to other environmental benefits. In Kenya, the crop is mainly grown and managed by smallholder farmers. Over the last two decades, banana ... -
Variation in nitrogen fixation among three Bush Bean cultivars grown in Kenya when inoculated with three Rhizobia Strains
