(Informa Uk Limited, trading as Taylor & Francil Group, 2019-12-10)The two complete mitochondrial genomes were sequenced from the freshwater monogonont rotifer Brachionus rubens. The genome sequences were 12,041 bp and 13,793 bp in size, and the gene order and contents were identical to ... -
Blending fishwastes and chicken manure extract as low-cost and stable diet for mass culture of freshwater zooplankton, optimized for aquaculture
(IOP Publishing, 2019)This study investigated the feasibility of fishwastes and chicken manure extract (CME) as cheap diet for mass culture of freshwater zooplankton. CME and fishwastes as well as carbon source were used to make fishwaste ... -
Utilization of the earthworm, Eisenia fetida (Savigny, 1826) as an alternative protein source in fish feeds processing
(Aquaculture Research Wiley, 2018-11-27)Use of fish meal in aquaculture is gradually becoming unsustainable due to com‐ petition, cost and ecological challenges hence the need to expand the alternative protein sources. The earthworm, Eisenia fetida is among ... -
Efficiency of pumpkin (Cucurbita pepo), sweet wormwood (Artemisia annua) and amaranth (Amaranthus dubius) in removing nutrients from a smallscale recirculating aquaponic system
(Aquaculture International, 2019-08-28)In aquaponic systems, plants absorb dissolved nutrients from aquaculture wastewater for their growth. The removal of nutrients allows reuse of water and minimises wastewater discharge to the surrounding environment. This ... -
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 ... -
In vitro organic matter disappearance of tanniferous browse using rumen liquid from goats ingesting grass versus browse
(Taylor & Francis, 2013-12-01)In vitro organic matter disappearance (IVOMD) of African browse species often indicates artificially low nutritive value due to the presence of condensed tannins (CT). Diet of the rumen liquor donor may change this if it ... -
Farmer Perceptions of Imazapyr-Resistant (IR) Maize Technology on the Control of Striga in Western Kenya
(2008)For a long time, farmers in Nyanza and Western provinces in Kenya have had to deal with the Striga problem. To most of them, Striga had become a way of life and they had given up hope. Striga affects their mainstay crops, ... -
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 ... -
Farmer perceptions of Imazapyr Resistant (IR) maize on the control of Striga in Western Kenya
(2008)For a long time, farmers in Nyanza and Western provinces in Kenya have had to deal with the Striga problem. To most of them Striga had become a way of life and they had given up hope. Striga affects their mainstay crops, ... -
Striga management and the African farmer
(SAGE Publications, 2008-12)Striga asiatica and S. hermonthica are widespread plant parasites of cereals in Sub-Saharan Africa. In maize cropland alone, Striga has infested about 2.4 million ha, resulting in yield loss of 1.6 million tons per year, ... -
Evaluation of Yield Advantage of Maize+ Artemisia And Maize+ Beans Intercrops In a Sub-Humid Ecozone Of Maseno, Western Kenya.
(2012)An experiment on intercropping systems at Maseno, western Kenya sought to evaluate the yield potential of maize indifferent maize+artemisia spacing regimes in comparison to a standard maize+bean system, by identifying the ... -
Herbicide applied to imidazolinone resistant-maize seed as a Striga control option for small-scale African farmers
(Weed Science Society of America, 2012-04)Striga is a major constraint to food production in Africa. Most technologies developed for the eradication of Striga asiatica from the United States are not adaptable to Africa. Imazapyr and pyrithiobac coated imidazolin ... -
Phytotoxic effect of selected crude plant extracts on soil-borne fungi of common bean
(African Crop Science Society (Uganda), 2010)Common bean (Phaseolus vulgaris L.) is an important food and cash crop particularly in Eastern, Southern and Great lake region. The efficacy of water based crude plant extracts of Neem (Azadirachta indica), Mexican marigold ... -
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 ... -
Economic analysis of different options in integrated pest and soil fertility management in maize systems of Western Kenya
(Blackwell Publishing Inc, 2010-09-01)The major biotic constraints to the production of maize, the major staple food in Western Kenya, are field pests such as Striga and stem borers, and low soil fertility. To counter these constraints, new cropping systems ... -
Economic efficiency and supply response of women as farm managers: Comparative evidence from Western Kenya
(Pergamon, 2008-07-01)This paper assessed the relative economic efficiency and output supply and input demand responses of women farmers in western Kenya. The results showed that women are as technically and allocatively efficient as men. ... -
Integrated management of Striga hermonthica, stemborers, and declining soil fertility in western Kenya
(Elsevier, 2008-05-10)Striga hermonthica (Delile) Benth., stemborers, and declining soil fertility are serious threats to sustainable food production in the Lake Victoria zone of Kenya. To address these constraints, promising integrated crop ... -
Amplification of 1-amino-cyclopropane-1-carboxylic (ACC) deaminase from plant growth promoting rhizobacteria in Striga-infested soil
