Nematode diversity and its association with soil properties in monocrop pigeon pea
(Elsevier, 2022-08)Pigeon pea is a versatile pulse crop grown in semi-arid regions of Kenya; however, its production is affected by plant-parasitic nematodes. The current study was undertaken to investigate the diversity of nematodes and ... -
Nematode diversity and its association with soil properties in monocrop pigeon pea
(Elsevier Ltd, 202-07-03)Pigeon pea is a versatile pulse crop grown in semi-arid regions of Kenya; however, its production is affected by plant-parasitic nematodes. The current study was undertaken to investigate the diversity of nematodes and ... -
Nematode diversity in soil from a field trial with decomposing Bt cotton expressing Cry1Ac and Cry2Ab2 protein
(2013)The quality of decomposing plant materials may affect the soil community structure. The aim of the study was to determine the impact of decomposing Bt cotton and its isoline on soil nematode diversity. Bt cotton (06Z604D), ... -
Nematode metabolic footprints, ecological and functional indices in tropical maize-beans agro-ecosystems under different farming practices
(Elsevier, 2020-10)Maize and beans contribute significantly to food security in Kenya. Farming practices used in production of these crops may affect nematode community assemblages and influence agricultural productivity. Information on ... -
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), ... -
Numerical simulation of the deterministic model of the under-five year’s pneumonia in Kenya
(2016)In this paper the numerical simulation of the childhood pneumonia deterministic model are determined. The estimated parameters and the under-five year’s population data for year 2013 was used to simulate the developed ... -
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 and distribution of soil nematodes in cotton production areas of Kenya.
(2010)A baseline survey was conducted to determine the occurrence and distribution of soil nematodes associated with cotton in major growing areas in Kenya. Such baseline data on soil nematode abundance, diversity and ecosystem ... -
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)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 significant ... -

On Analytical Approach to Semi-Open/Semi-Closed Sets
(2017-03)The concept of open and closed sets has been extensively discussed on both metric and topological spaces. Various properties of these sets have been proved under the underlying spaces. However, scanty literature is available ... -
On the Performance of L- and V-Shaped Arrays of Cardioid Microphones for Direction Finding
(IEEE, 2021-01-15)The L-shaped and V-shaped arrays of first-order cardioid microphones for direction finding are presented in this paper. A comparative study of the direction of arrival estimation performance of the arrays was carried out ... -
Optimizing use of integrated soil fertility management options for profitable groundnut production in Uganda
(2014-09)Soil fertility decline is a major constraint to groundnut production in Uganda. Whereas options exist to address this constraint, many have not been adopted by smallholder farmers. This study was designed to demonstrate ... -
