phenotypic nutrient up-take differences in an alley cropping system in semi-arid machakos, kenya.alley cropping of cassia siamea and maize was studied in semi-arid kenya for soil fertility improvement. katumani composite maize was planted except in the short rains of 1988 (sr88) when a hybrid variety was sown. therefore the grain yield per row increased differently in the alley cropped maize (cm). sole maize (sm) and cm yields were higher in sr88 than in the long rains of 1988 (lr88) by 62% and 38%, while yields from the same treatments in lr89 were only 21% and 45% of those in sr88. these ...200111590735
understanding yields in alley cropping maize (zea mays l.) and cassia siamea lam. under semi-arid conditions in machakos, eastern kenya.six seasons of experiments in machakos, kenya, revealed that above about 150 mm of rainfall, maize yields per row in alley cropped "replacement" agroforestry (af) plots, of cassia siamea lam. and maize (zea mays, cv. katumani composite b), may be expected to exceed those in the control (sole maize) plots. such yields were insufficient to compensate for the area "lost" to the hedgerows. below about 150 mm the control plots may be expected to perform better. this result was due to competition for ...200111590758
outbreak of aflatoxin poisoning--eastern and central provinces, kenya, january-july 2004.in may 2004, cdc kenya, trainees of the cdc-supported field epidemiology and laboratory training program (feltp) in kenya, the world health organization, and cdc were invited by the kenya ministry of health (kmoh) to participate in the investigation of an outbreak of jaundice with a high case-fatality rate (cfr) in the districts of makueni and kitui, eastern province. preliminary laboratory testing of food collected from the affected area revealed high levels of aflatoxin, suggesting that the ou ...200415343146
aflatoxin levels in locally grown maize from makueni district, kenya.investigations were carried out to determine aflatoxin levels in household maize in makueni district and to correlate aflatoxin levels to maize drying and storage practices. also, aflatoxin exposure in villages that reported aflatoxicosis cases in 2005 was compared with that in villages that did not report cases to assess whether aflatoxin exposure levels could be used to identify high-risk villages for targeted prevention interventions.200819133419
aflatoxin levels in maize and maize products during the 2004 food poisoning outbreak in eastern province of kenya.on 10th may, 2004 food samples suspected to have caused acute poisoning in makueni district were received at the national public health laboratory services (nphls). on analysis, they were found to be highly contaminated with aflatoxin b1. more cases of poisoning were reported in the district and in neighbouring districts of kitui, machakos and thika. as at 20th july, 2004 the ministry of health was aware of 317 cases of which 125 resulted in deaths.200516175776
impact of aspergillus section flavi community structure on the development of lethal levels of aflatoxins in kenyan maize (zea mays).to evaluate the potential role of fungal community structure in predisposing kenyan maize to severe aflatoxin contamination by contrasting aflatoxin-producing fungi resident in the region with repeated outbreaks of lethal aflatoxicosis to those in regions without a history of aflatoxicosis.201019674186
aflatoxin contamination of commercial maize products during an outbreak of acute aflatoxicosis in eastern and central kenya.in april 2004, one of the largest aflatoxicosis outbreaks occurred in rural kenya, resulting in 317 cases and 125 deaths. aflatoxin-contaminated homegrown maize was the source of the outbreak, but the extent of regional contamination and status of maize in commercial markets (market maize) were unknown. we conducted a cross-sectional survey to assess the extent of market maize contamination and evaluate the relationship between market maize aflatoxin and the aflatoxicosis outbreak. we surveyed 6 ...200516330360
