Increasing imazapyr-resistant maize yield by increasing plant density under natural Striga hermonthica infestation
(ScienceHuß, 2010)Maize (Zea mays L.) is one of the most important crops in East Africa serving both as a staple food and cash crop to millions of people. As a vegetable, it is produced as green maize cobs, sweet corn or baby corn. Yields ... -
Yield of three commercial watermelon cultivars in Kenya as compared to a local landrace
(African Journal of Horticultural Science, 2010)High yield is a major goal for watermelon (Citrullus lanatus) breeders. The objective of this study was to measure the yield potential of some watermelon accessions available in Kenya and identify high yielding ones for ... -
Effects of water deficit on physiology and morphology of three varieties of nerica rainfed rice (Oryza sativa L.)
(2010)Water deficit is a major problem in rice grown under rainfed conditions. It affects plant growth and development and ultimately leads to a considerable yield reduction or crop failure. Although the rice crop is susceptible ... -
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 ... -
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 ... -
Participatory evaluation of integrated pest and soil fertility management options using ordered categorical data analysis
(Elsevier, 2010-06-01)Maize is becoming the major food crop around Lake Victoria. Major constraints to its production are Striga, stem borer, and declining soil fertility. Innovative integrated technologies have been developed: the ‘push–pull’ ... -
Responses of ecosystem carbon dioxide fluxes to soil moisture fluctuations in a moist Kenyan savanna
(Cambridge University Press, 2010-11-01)Measurements were conducted within a fence-exclosure between February 2008 and July 2009 to investigate the influence of soil moisture on ecosystem CO₂ fluxes in a Themeda triandra-dominated grassland of a humid Kenyan ... -
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 ... -
Physiological and biochemical responses of five nerica rice varieties (Oryza sativa L.) to water deficit at vegetative and reproductive stage
(2012)Food shortage is a major problem in sub Saharan Africa as population increases. Over 89% of Kenyans are food poor and are malnourished especially in rural areas. NERICA (New Rice for Africa) are high yielding rainfed ... -
Unravelling the potential of sweet sorghum for sugar production in Kenya
(Third RUFORUM Biennial Meeting, 2012)Sorghum (Sorghum bicolor (L.) Moench is an important food and increasingly industrial crop and serves as a source for starch and sugars for biofuel production world wide and especially in sub-Saharan Africa. Sweet sorghum ... -
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 ... -
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. ... -
Screening of Sweet Sorghum (Sorghumbicolor (L.) Moench) Varieties for Sugar and Biomass Production
(Springer India, 2013-09-01)Sweet sorghum has elicited the interest of breeders due to its capacity to provide renewable energy products, industrial commodities, food and animal feed. Whereas the technologies to process sugar products from sweet ... -
Allelopathic effects of mexican sunflower [tithonia diversifolia (hemsl) a. Gray] on germination and growth of cowpea seedlings (vigna sinensis)
(2014)Allelopathy is a common among plants. Allelopathic substances affect seed germination, plant growth and development or even affect chlorophyll synthesis by the plant leaves. Tithonia diversifolia contains allelochemicals that ... -
