Aspergillus species and Aflatoxin b1 in soil, maize grain and flour samples from semi-arid and humid regions of Kenya
(Department of Plant Science and Crop Protection, University of Nairobi, 2012)Recurrent outbreaks of Aflatoxin (AF) poisoning in maize continue to exacerbate the food security crisis in Sub-Saharan Africa. This study determined the distribution and contamination levels of Aspergillus spp. and Aflatoxin ... -
Combing ability of maize (Zea Mays) inbred lines resistant to striga hermonthica (Del.) Benth evaluated under artificial striga infestation
(University of Nairobi, Faculty of Agriculture, 2014-04-17)The parasitic weed Striga affects maize on an estimated 20 million ha in Africa, making it a major cause of maize yield reduction from near world average of 4.2t/ha few decades ago to the present 1.5 t/ha. The objectives ... -
Combining abilities of maize inbred lines for grey leaf spot (GLS), grain yield and selected agronomic traits in Kenya
(Department of Plant Science and Crop Protection, 2013)The genetics of resistance to grey leaf spot (GLS) disease, grain yield and selected agronomic traits was studied in 42 F1 progenies from a full diallel cross among seven maize inbred lines. These 42 F1 progenies and seven ... -
Comparison of the Effectiveness of Zero Tillage and Intercropping on Weed Management in Maize (Zea mays L.)
(Department of Plant Science and Crop protection, University of Nairobi, 2012)Maize is an important cereal worldwide and weeds are a major constraint to production. A trial was conducted in Kigumo, Murang’a County, Central Province of Kenya in 2010 to compare the effects of glyphosate and intercropping ... -
Contour Hedgerows and Grass Strips in Erosion and Runoff Control on Sloping Land in Semi-Arid Kenya
(Taylor and Francis GroupDepartment of Meteorology, University of Nairobi,Department of Agricultural Engineering, University of Nairobi,, 2007)Most early alley cropping studies in semi-arid Kenya were on fairly flat land while there is an increase in cultivated sloping land. The effectiveness of aging contour hedgerows and grass strips for erosion control on an ... -
Effects of Intercropping Young Plants of the Compact Arabica Coffee Hybrid Cultivar Ruiru 11 with Potatoes, Tomatoes, Beans and Maize on Coffee Yields and Economic Returns in Kenya
(Department of Plant Science and Crop Protection, University of Nairobi, 1993)The effects of intercropping young plants of the compact arabica coffee hybrid cultivar Ruiru 11 with potatoes, tomatoes, maize and Phaseolus (dry) beans were studied between 1987 and 1989 at Ruiru in Kenya. Yields of clean ... -
The effects of legume and maize stover residue management practices on the yield of a subsequent maize crop in Kitale, Kenya
(2015-06-13)A trial focusing on the management of Mucuna pruriens (mucuna) and maize stover residues was conducted over two seasons on a low fertility soil in the North Rift region of Kenya. The effects of factorial combinations of ... -
Effects of soil management practices and tillage systems on soil moisture conservation and maize yield on a sandy loam in semiarid Kenya
(Taylor & FrancisDepartment of Soil Science, University of NairobiKenya Agricultural Research Institute,, 2005)Maize is an important crop in the high and medium rainfall areas of Kenya and thus, there is a need for additional information on the effect of tillage and soil management practices on water conservation and yield of maize. ... -
Evaporation from soils below sparse crops in contour hedgerow agroforestry in semi -arid Kenya
(Department of Meteorology, University of NairobiDepartment of Agricultural Engineering, University of Nairobi,, 2005)In many agricultural systems in the semi-arid tropics, crops use only a small fraction of the total rainfall. Agroforestry can greatly reduce some losses, especially on hi II slopes, where soi I evaporation, runoff and ... -
The fate of afiatoxins during processing of maize into muthokoi - A traditional Kenyan food
(Department of Public Health, Pharmacology and Toxicology, 2008)The effect of processing muthokoi, (a traditional dehulled maize dish in Kenya) on aflatoxin content of naturally contaminated maize was investigated. Dehulling decreased aflatoxin levels by 46.6% (5.5-70%) in maize samples ... -
Infectious structures and response of maize plants to invasion by Exserohilum turcicum (Pass). in compatible and incompatible host pathogen systems.
(Department of Plant Science and Crop Protection, University of Nairobi, 2008)Objective: To study the differential response of corn leaves to invasion by Exserohilum turcicum comparing compatible and incompatible host-pathogen systems. Methodology and results: Maize leaves excised from 14 day-old ... -
Intake of nutrients from scavengeable resources by scavenging chickens supplemented free choice with protein and energy
(Department of Animal Production, University of Nairobi, 2009)A study was conducted under farm conditions and management to estimate nutrient intake from scavengeable resources, provide information on diurnal nutrient intake and effects of supplementation with energy (maize ... -
Productivity of farmer-preferred maize varieties intercropped with beans in semi-arid Kenya
(Department of Plant Science and Crop Protection, University of Nairobi, 2013)Farmers in the semi-arid regions grow drought tolerant maize varieties and practice maize-legume intercropping. A study was conducted in Machakos, Mwea and Waruhiu in 2008 short rains and 2009 long rains to determine the ... -
Quality protein maize for the feed industry in Kenya
(University of Nairobi.Faculty of Veterinary Medicine, 2010)Quality protein maize (QPM) has increased levels of lysine and tryptophan, limiting amino acids for monogastric animals, so its use in animal feed reduces the need for more expensive high-protein sources. The authors, ... -
Residual Effect of Mucuna pruriens Green manure Application Rate on Maize (Zea mays L.) Grain Yield
(Department of Agricultural Economics, 2010)Maize grain yield is constrained by inadequate supply of nitrogen caused by insufficient application of fertilizers that are found to be costly and unaffordable in smallholder farming. Therefore there is need to search ... -
Sclerotia Formation and Toxin Production in Large Sclerotial Aspergillus flavus Isolates from Kenya
(2016)We studied the relationship between sclerotia formation and aflatoxin production by Aspergillusflavus strains isolated from maize kernels from Nandi County. Isolates recovered from maize kernels were tested for their ability ... -
