General and specific combining ability for grain and yield components in a diallel cross among selected nine inbred lines of maize (Zea mays L)
(Maseno University, 2023)Analysis of combining ability plays an important role in identifying elite parents and crosses which can give best combinations based on the performances of their offspring. Hybrid variety production requires broad genetic ... -
Characterization of the Genetic Diversity of Cercospora Zeina in Kenya and Mapping the QTL for resistance to Gray Leaf Spot and Turcicum Leaf Blight in Maize
(Maseno university, 2022)Gray leaf spot (GLS) caused by Cercospora zeina in Africa and Turcicum leaf blight (TLB) caused by Exserohilum turcicum are a major threat to maize production due to the associated grain yield losses. Resistance in the ... -
Determination of Agricultural Production Constraints and Optimal Enterprise. Mix in an Irrigation Scheme: The Case of HOLA Irrigation Scheme in Kenya
(University of Nairobi, 1992)This study arose out of the need to address the problem of poor performance of Kenya's large scale irrigation schemes. The poor performance has been evidenced by the negative cash flows that these schemes have consistently ... -
Genetic Diversity of Legume Nodulating Bacteria and the Effect of Nitrogen Sources on the Yield of Common Bean in Western Kenya
(Maseno University, 2016)Declining soil fertility in general and nitrogen (N) in particular limit crop production on many smallholder farms in western Kenya. Soil N deficiency is usually ameliorated with inorganic N fertilizers but their high costs ... -
Phenotypic variation in morphology, yield and seed quality in selected accessions of leafy Amaranths
(Maseno University, 2017)Vegetable amaranths are highly valued for being rich in proteins and micronutrients such as iron, calcium, zinc, vitamin C and vitamin A. In spite of the crop’s exceptional nutritional qualities, very little effort has ... -
Identification of Maize (Zea Mays L.) Genotypes Resistant to Striga Hermonthica (Del.) and Determination of Genetic Basis for Resistance
(Maseno University, 2017)The obligate root hemi-parasite, Striga hermonthica (Del.) Benth., native to sub-Saharan Africa causes serious economic constraint to cereal production. There has been limited study to understand the genetics of Striga ...
