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. ... -
Comparative analysis of immediate and residual effects of farmyard manure, triple superphosphate, and lime on maize yields in western Kenya
(African Journal of Agricultural Research, 2023-10-26)The effects of farmyard manure (FYM) and triple superphosphate (TSP) as sources of phosphorus, when applied with or without lime, on selected soil chemical properties, and the initial and residual maize yields, were ... -
Comparative effects of lime and organic materials on selected soil chemical properties and nutrient uptake by maize in an acid soil
(Scholars Research Library, 2011)The use of phosphate fertilizers and lime to mitigate P deficiencies and Al toxicities in Kenya has not been effective due to their high cost. Organic materials (OMs) are therefore being tested as cheaper alternatives but ... -
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 ... -
Comparison of economic impact of alternative constraint control measures in indigenous chicken production in Nyanza Province, Kenya
(CIPAV Foundation, 2013)This study compared the costs and benefits of six alternative control measures on the indigenous chicken productivity constraints with an aim of identifying the most desirable mitigation measure; for improved productivity ... -

Comparison of effects of phosphorus sources on soil acidity, available phosphorus and maize yields at two sites in western Kenya
(Taylor & Francis, 2013-03-01)The effects of farmyard manure (FYM), Tithonia diversifolia (tithonia) and urea when applied alone or in combination with Minjingu phosphate rock (MPR), Busumbu phosphate rock (BPR) or triple superphosphate (TSP) on soil ... -
Comparison of net fish yields in pond cultured Nile tilapia (Oreochromis niloticus L.) fed on peanut-based meals as alternatives to dietary fishmeal
(International Journal of Fisheries and Aquatic Studies, 2021)Although net yield directly relates to actual production at harvest, feeding trials aimed at replacing dietary fishmeal in cultured fish have largely ignored the performance indicator. A 16-week experiment aimed at ... -
Complete mitochondrial genome of the freshwater monogonont rotifer Brachionus angularis (Rotifera, Brachionidae)
(College of Science, Sungkyunkwan University, Suwon 16419, South Korea, 2020)The two complete mitochondrial genomes were sequenced from the freshwater monogonont rotifer Brachionus angularis. The mitochondrial genome sequences were 10,764 bp (mitochondrial DNA I) and 12,238 bp (mitochondrial DNA ... -
