Early Agronomic Performance of Some New and Existing Arabica Coffee Varieties in Kenya
(2015)The primary goal of plant breeding is to improve yield, quality and disease resistance. However, majority of reported work on coffee breeding primarily concerns agronomical improvement that directly impinges on either ... -
Effect of Bt cotton expressing Cry1Ac and Cry2Ab2 protein on soil nematode community assemblages in Mwea, Kenya
(2013)Objective: The nematode community structure in soil cultivated with Bt cotton (containing Cry1Ac and Cry2Ab2 protein), isoline (non Bt cotton) and HART 89M (non Bt cotton) was evaluated in a field trial at Ndomba in the ... -
Effect of Climate Change on Small Scale Agricultural Production and Food Security in Kitui District, Kenya
(World Science and Research Publishing, 2014-10)Most of the world’s arid and semi-arid lands (ASALs) are found in the developing countries. These ASALs face many challenges some of which are as a result of the declining availability of water resources and increasing ... -
Effect of decomposition intensity of incorporated chickpea manure on stability and saturated hydraulic conductivity of a clay loam and clay soil
(Academic Journals, 2011-03-04)The role of organic matter (OM) in soil aggregation and saturated hydraulic conductivity (Ksat) has long been recognised but their depedence on the intensity of decay is less studied. The objective of this study was to ... -
Effect of incorporating Cassia siamea prunings on maize yield in an alley cropping trial in semiarid Kenya
(1997)The influence of soil-incorporated Cassia siamea prunings on nutrient status of maize leaves, grain and yield was studied in an alley cropping experiment in semiarid Machakos, Kenya, during the 1988 long and short rainy ... -
Effect of moisture content on the physical properties of three varieties of sorghum seeds
(Elsevier, 2006-08-31)Three sorghum varieties (Kari-mtama, Serena and Seredo) were obtained from the Kenya Agricultural Research Institute and reconditioned to moisture contents ranging from 13.64% to 21.95% db. The reconditioned grain kernels ... -
Effect of plant biomass, manure and inorganic fertilizer on maize yield in the central Highlands of Kenya
(2007)Soil fertility degradation remains the major biophysical cause of declining per capita crop production on smallholder farms in sub-Saharan Africa. Appropriate soil fertility regimes, are therefore, critical for improved ... -
Effect of Reduced Tillage and Mineral Fertilizer Application on Maize and Soybean Productivity
(2012)Reduced tillage is said to be one of the potential ways to reverse land degradation and ultimately increase the productivity of degrading soils of Africa. We hypothesised that crop yield following a modest application of ... -
Effect of time of Azolla incorporation and inorganic fertilizer application on growth and yield of Basmati rice
(Academic Journals, 2020-03)Azolla tissue contains 5% N, which is slowly released into the soil upon decomposition. Timing of incorporation is therefore important for maximum benefit to a crop. The effect of time to incorporate Azolla biomass on ... -
The effects of exchange rate liberalization in Kenya on French beans exports
(Pak Publishing Group, 2014)The adoption of a floating exchange rate system in Kenya was an effort to make it more aligned to the market determined equilibrium rate. However, there is limited empirical evidence that success has since been achieved ... -
Effects of Exchange Rate Volatility on French Beans Exports in Kenya
(Springer, 2014-01)In Kenya, exports of French beans are one of the leading foreign exchange earners. Nevertheless, the economic impacts of exchange rate volatility on French beans exports in Kenya are unclear. This paper evaluates the ... -
Effects of Market Reforms on Irish Potato Price Volatility in Nyandarua District, Kenya
(2013)This paper evaluates the effects of market reform policies on the volatility of Irish potato prices in Kenya through an analysis of a 20 year monthly time series data set from Nyandarua district using an autoregressive ... -
Effects of organic and mineral fertilizer inputs on maize yield and soil chemical properties in a maize cropping system in Meru South District, Kenya
(Springer, 2007-01)Soil nutrient depletion as a result of continuous cultivation of soils without adequate addition of external inputs is a major challenge in the highlands of Kenya. An experiment was set up in Meru South District, Kenya ... -
Effects of Selected Plants' Extracts on in vitro Growth of Rahtonia slanacearum (Smith), the Causal Agent of Bacterial Wilt of Irish Potatoes
(Asian Network For Scientific Information, 2011)The antibacterial effect of crude medicinal plant extracts of Ocimum gratissimum, Brassica oleracea var. botrytis and Ipomoea batatas on Rahtonia solanacearum (Smith) extracted from infected potato tubers was determined ... -
Effects of Variety, Spacing and Nitrogen Application on Chickpea (Cicer arietinum) Growth and Yield in Embu County, Kenya
(2022-02)Chickpea is a pulse crop that is rich in proteins and helps in fulfilling the requirement of protein for vegetarian people thus yield maximization needed. This study aimed to determine the effects of spacing, nitrogen ... -
Efficacy of Metarhizium anisopliae (Mechnikov) Sorokin ICIPE 69 against the melon fly Zeugodacus cucurbitae (Coquillett) infesting courgette (Cucurbita pepo L.) in field cages
(UoEm, 2023-07-21)Effective integrated pest management (IPM) of the melon fly Zeugodacus cucurbitae (Coquillett), a devastating pest threatening horticultural production in Africa, is urgently needed. In this study, a c ... -
Enhancing legume crop pollination and natural pest regulation for improved food security in changing African landscapes
(Elsevier, 2020-09)Legumes are important crops for food security, consumed by millions of people especially in Africa where they are an essential protein source and provide key vitamins and minerals. Most legumes depend on insect pollination ... -
Evaluation of Leucaena leucocephala as a source of N for maize
(1997-01)Prunings of leucaena [Leucaena leucocephala (Lam.) De Wit] have long been regarded as a useful alternative to N fertilizer, but N use efficiency by crops is often low. The potential exists to synchronise nutrient ... -
Evaluation of photoperiod and thermosensitive genic male sterile lines for hybrid rice seeds production in Kenya
(2013)Photo–thermo-sensitive genic male sterile (P(T)GMS) rice is a new hybrid rice technology that uses prolonged light length and high temperatures to induce sterility. This technology is being introduced in Kenya but such ... -
