Assessment of four commercial watermelon cultivars and one local landrace for their response to naturally occurring diseases pests and non-pathogenic disorders in sub-humid …
(Asian Research Publishing Network (ARPN), 2008)Four commercial watermelon cultivars available in Kenya and one local landrace were evaluated for their susceptibility/resistance to naturally occurring diseases, pests and non-pathogenic disorders. The accessions included ... -
Bacteriological and Physicochemical characterisation of AoraLoko Stream water,Maseno kenya
(AESS Publications, 2017)Safety and quality of drinking water is an important aspect in public health. Water pollution is one main cause of worldwide diseases and death. Human activities around water catchment areas contribute to some level ... -
Carbon dioxide exchange and biomass productivity of the herbaceous layer of a managed tropical humid savanna ecosystem in western Kenya
(Oxford University Press, 2013-08-01)Aims Humid savannas, as a result of high precipitation amounts, are highly productive. They are also hotspots for land use change and potential sources of carbon dioxide (CO2) due to the large soil carbon (C) stocks. ... -
Carpet Characteristics of Eichhornia Crassipes [Mart.] Solms (Water hyacinth) in the Winam Gulf (Lake Victoria, Kenya)
(Asian Economic and Social Society, 2017)The occurrence and spread of the water hyacinth (Eichhornia crassipes [Mart.] Solms), in the Winam gulf has created numerous attributes to the human population that live around the lake, thereby making its control a ... -
Chlorophyll fluorescence parameters and photosynthetic pigments of four Glycine max varieties under Aluminium chloride stress
(2015)Soy bean (Glycine max L.) is a commonly grown legume crop in Kenya. Soy bean grains are among the world's most important in terms of protein content of 35-40% and oil content of 15- 22%. Soy bean grains are also rich ... -
Chlorophyll fluorescence, protein and chlorophyll content of three nerica rainfed rice varieties under varying irrigation regimes
(2010)Water deficit affects growth and development of rainfed rice leading to a considerable yield reduction or crop failure. Although the rice crop is susceptible to water deficit, there is a marked genotypic variation in ... -
Combination of linkage and association mapping with genomic prediction to infer QTL regions associated with gray leaf spot and northern corn leaf blight resistance in tropical maize
(Frontiers, 2023-11-07)Among the diseases threatening maize production in Africa are gray leaf spot (GLS) caused by Cercospora zeina and northern corn leaf blight (NCLB) caused by Exserohilum turcicum. The two pathogens, which have high genetic ... -
Combining ability of parents and hybrids for sugar yield and its attributing traits in sweet sorghum [Sorghum bicolor (L.) Moench]
(Springer India, 2017-02-01)An investigation was carried out to assess the combining ability and nature of gene action in respect of sugar yield and its attributing traits in 25 new hybrids of sweet sorghum developed by crossing five (5) high-sugar ... -
Community Tree Seedling Production in Maseno Division, Kenya
(IJRIAS), 2019-07)Forests and trees are important natural resources globally. The reduction of forests and tree cover has occasioned the loss of biodiversity, wildlife habitat, ecosystem integrity; increased climate variability and reduced ... -
Comparative analyses reveal high levels of conserved colinearity between the finger millet and rice genomes
(Springer-Verlag, 2007-08-01)Finger millet is an allotetraploid (2n = 4x = 36) grass that belongs to the Chloridoideae subfamily. A comparative analysis has been carried out to determine the relationship of the finger millet genome with that of rice. ... -
Comparing the yield components of three most popular commercial watermelon cultivars in Kenya with one newly introduced cultivar and one landrace
(Academic Journals, 2009)High yield is a major goal for watermelon (Citrullus lanatus) breeders. The objective of this study was to compare the yield components of some watermelon accessions available in Kenya and to identify high yielding ... -
Depletion of phosphate rock reserves and world food crisis: Reality or hoax?
(African Journal of Agricultural Research, 2020)Phosphate rock (PR) deposits are the major source of phosphate (P) fertilizers for soil fertility replenishment. The demand for P fertilizers in the year 2014 was 42,706,000 tons and was expected to reach 46,648,000 tons ... -

Determining the Incidence and Severity of Maize Ear Rot Disease in Western Kenya
(Emerging Challenges in Agriculture and Food Science, 2022-09-28)The purpose of this study is to determine the incidence and severity of the symptoms of ear rot in the four counties in Western Kenya. Maize ear rot disease is caused by a complex relationship involving the fungal pathogens; ... -
Ecology and Physiology of Plant growth in relation to soil salinity
(2015)This work is intended as a review of soil salinity as one common abiotic stress in ecological systems that adversely affect plant growth. In arid and semi arid areas, saline areas or areas irrigated with saline waters, ... -
Economic Evaluation of Organic and Inorganic Sources of Nitrogen under Striga Infestation in Western Kenya
(Journal of Experimental Agriculture International, 2020)Due to escalating cost of imported fertilizers, there is renewed interest in the use of local nutrient resources in managing soil fertility in Kenya. The effect of integrated use of urea and Calliandra or maize stover ... -
Ecosystem productivity and CO2 exchange response to the interaction of livestock grazing and rainfall manipulation in a Kenyan savanna
(Elsevier, 2021)Savanna ecosystems in Kenya are experiencing altered rainfall amount and increased grazing pressure. These environmental alterations occur simultaneously and impact on productivity and CO2 exchange of the savanna in unclear ... -
Effect of inoculation with Klebsiella oxytoca ‘10 mkr 7’on striga suicidal germination in Zea mays
(2008)The Striga species are obligate root parasitic plants. Plant growth promoting rhizobacteria could enhance Striga suicidal germination. In screen-house studies we quantified the effect of bacterial inoculation with ... -
Effect of intercropping maize and beans on striga incidence and grain yield
(2001-02-15)Intercrops can smother weeds in cereal crops and improve the overall productivity. Although intercropping with beans has long been practised in the region, a practical bean population and arrangement is required in the ... -
