Influence of Climatic Factors on the Δ13c Values of the C3, C4 And CAM Dicot Species (Vegetation) of the Centrospermeaealong Altitudinal Gradient in western Region of Kenya
(Research Gate, 2017)Species of the Centrospermeae occurring at different altitudes were analyzed for δ13C values and assigned for graphical representation. The aridity of the study area was evident as defined using the Klimadiagramm. Climatic ... -
Influence of nitrogen supply on photosynthesis, chlorophyll content and yield of improved rice varieties under upland conditions in Western Kenya
(sciencedomain., 2016-07-09)Rice (Oryza sativa) is a principal staple food crop in Kenya. However, its production is still low due to inherently low and declining soil fertility. This has resulted into food and nutritional insecurity and low living ... -
Influence of NPK Blended Fertiliser on Soil Chemical Properties under Acidic Conditions of Western Kenya on Finger Millet Crop
(Asian Research Journal of Agriculture, 2017)Soil acidity is a serious problem that affects crop productivity in Western Kenya region. The county governments of Kakamega, Bungoma, Vihiga, Busia and Trans-Nzoia are promoting the application of NPK blended fertilizer ... -

Influence of Organic and Inorganic Sources of Fertilizer on Growth and Leaf Yield of Kale (Brassica oleraceae Var. Acephala DC)
(AGRICULTURAL SCIENCE AND TECHNOLOGY INFORMATION, 2005)Brassica oleraceae var. Acephala D.C. (kale, sukuma wiki) is the most important vegetable in Kenya but its production is hampered by low soil fertility particularly Nitrogen and Phosphorus. Most small holder farmers do not ... -
Influence of rainfall amount and livestock grazing on soil respiration in a moist Kenyan savannah
(African Journal of Ecology, 2019)The influence of livestock grazing and changing rainfall patterns on soil respiration (Rs) in the tropical savannah in Lambwe is unclear. Measurements of Rs using chambers were conducted between June and November 2012 in ... -
Influence of region of production on clonal black tea chemical characteristics
(Elsevier, 2008-05-01)Production of black tea from the same vegetatively propagated (VP) cultivars, in Kenya and Malawi, shows variations in both chemical composition and quality. Whereas it is possible to produce black teas with similar total ... -
Inheritance of resistance to the spotted stem borer, chilo partellus, in a maize population.
(Kenya Agricultural Research Institute, Nairobi (Kenya), 2006)The spotted stem borer, Chilo partellus is an important insect pest of maize. It damages maize by feeding on the leaves and within the plant. Maize yield loss due to Chilo spp. Stem borer damage is estimated at 44 percent ... -
