New sources of resistance to spotted stem borer, Chilo partellus in sorghum
(2012)The lepidopteran Chilo partellus Crambid, an introduced pest in East and southern Africa from Asia, is the most economically important stem borer species infesting cereals in Africa. Chilo partellus causes more than 40% ... -
Nitrogen fertilizer equivalencies of organics of differing quality and optimum combination with inorganic nitrogen source in Central Kenya
(Kluwer Academic Publishers, 2004)Decline in crop yields is a major problem facing smallholder farmers in Kenya and the entire Sub-Saharan region. This is attributed mainly to the mining of major nutrients due to continuous cropping without addition of ... -
Nitrogen recovery by alley-cropped maize and trees from 15N-labeled tree biomass in the subhumid highlands of Kenya
(Springer-Verlag, 2000-05)The effectiveness of tree-leaf biomass as a source of N to crops in agroforestry systems depends on the rate at which crops can obtain N from the biomass. A study was conducted to determine the fate of 15N labeled, ... -
Novel source of sorghum tolerance to the African stem borer, Busseola fusca
(Academic Journals, 2012-08)Sorghum (Sorghum bicolor) is an important cereal food crop in semi-arid tropics, but its productivity is curtailed mainly by insect pests and diseases. The African stem borer, Busseola fusca Fuller (Lepidopteran: Noctuidae), ... -
Nutrient content of sorghum hybrid lines between Gadam and hard coat tannin sorghum cultivars
(Wiley, 2022-06)Sorghum is an important food crop in the world that exhibits a predominant role in fulfilling the nutritional requirements, particularly in low- income group populations of marginal areas in Kenya. It is a principal ... -
Nutritional and Phytochemical Composition of Bambara Groundnut (Vigna subterranea [L.] Verdc) Landraces in Kenya
(UoEM, 2023-06-02)Bambara groundnut (Vigna subterranea) is a highly nutritious legume with good drought tolerance attributes and is therefore a suitable candidate for food and nutritional security especially in drought prone areas. This ... -
Occurrence of Ck-1 gene conferring resistance to Coffee Berry Disease in Coffea arabica cv. Ruiru 11 and its parental genotypes
(SCIENCEWEB PUBLISHING, 2014-03)Abstract. Resistance to Coffee Berry Disease (CBD) in Coffea arabica cv. Ruiru 11 is known to be controlled by among others, the T (Ck-1) gene from Robusta coffee (Coffea canephora Pierre). The cultivar reportedly presents ... -
Partial Nucleotide Sequences of Sweet Potato Leaf Curl Virus Occurring in Kenya and its Phylogenetic Relationship with other Members of Begomoviruses
(2012-11)Sweet potato leaf curl virus has been reported in different sweet potato growing regions of Kenya. Partial nucleotide sequences of Kenyan Sweet potato leaf curl virus isolates were compared with other isolates from different ... -
Pathogenicity of Colletotrichumkahawae in Kenya
(2017-05)This study was aimed at determining the virulence diversity of Colletotrichumkahawae, and their correlation with coffee growing regions and interaction with coffee varieties in Kenya. A total of 34 single conidia isolates ... -
Performance assessment of Crosses between Gadam and Hardcore Tannin sorghum in hybrid lines production
(2022-06)Gadam cultivar of sorghum has been characterized by low yields compared to the international yield levels of sorghum. In this research, Gadam was crossed with Serena, Seredo, and Kari/Mtama-1 in an attempt to increase ... -
