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 ... -
The influence of PH on the recovery of contaminating micro-organisms from honey
(University of Nairobi, 1992)Accurate and sensitive methods for recovering contaminating micro-organisms from honey are required for an adequate control of the hygienic quality of the product. Most of these micro-organisms would be expected to be ... -
Adaptive nonparametric variance estimation for a ratio estimator
(Jomo Kenyatta University of Agriculture and Technology (JKUAT), 1997) -
Coenzyme Q10 prevented full blown splenomegaly and decreased melarsoprol-induced reactive encephalopathy in mice infected with Trypanosoma brucei rhodesiense
(Journal of Coastal Life Medicine, 1997)Objective: To establish the modulatory effects of coenzyme Q10 on experimental trypanosome infections in mice and evaluate the risk of occurrence and severity of melarsoprol-induced post treatment reactive encephalopathy ... -
Resilience of soils and vegetation subjected to different grazing intensities in a semi-arid rangeland of Kenya
(Taylor & Francis, 1997)The resilience of rangeland soils and vegetation to different levels of grazing is still poorly understood. A study was conducted to determine the recovery of a rangeland grazed at different intensities and allowed a ... -
Robust estimation of the error variance of the ratio estimator
(Egerton Journal of Humanities, Social Sciences and Education, 1999) -
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) -
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 ... -
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 ... -
Outlier Robustness of the Estimators of Variance of the Ratio Estimator
(Jomo Kenyatta University of Agriculture and Technology (JKUAT), 2002) -
Tree Layer Dynamics under Different Land Uses and Soils in Semi-Arid Areas of Kenya
(2002)A study was conducted to characterize the main factors critical to the distribution of key wood species and quantify the effects of land use on the tree layer in a semi-arid area of Kenya. Units studied were small-scale ... -
ROBUST ESTIMATION OF VARIANCE IN THE PRESENCE OF NEAREST NEIGHBOUR IMPUTATION
(African Journal of Science and Technology, 2003)The problem of estimating the variance of an estimator of the population total when missing values have been filled using a Nearest Neighbour (NN) imputation method is considered. The estimator is developed assuming a more ... -
Robust estimation of variance in the presence of nearest neighbour imputation
(African Network of Scientific and Technical Institutions (ANSTI), 2003)The problem of estimating the variance of an estimator of the population total when missing values have been filled using a Nearest Neighbour (NN) imputation method is considered. The estimator is developed assuming a more ...
