Segregation disortion of anthocyanin morphological marker in F2 population of cross between basmati and environment genic male sterile rice lines
(2013)Basmati rice (Oryza sativa L.) is preferred by many Kenyans yet its yield per hectare is low. This challenge led to initiation of Basmati hybrid rice project in Kenya with a goal of leaping yield benefits of heterosis. ... -
Selection of Ruiru 11 hybrid sibs on raw coffee quality
(2012-06)The economic value of Arabica coffee (Coffea arabica L.) is determined mainly by the yield potential, the size and shape of raw beans and beverage quality. Bean quality reportedly differ depending on the variety, environmental ... -
Selection within Coffea arabica cv. Ruiru 11 for high cup quality
(Academic Journals, 2012-09-26)In recent years, consumer awareness about the quality of different coffees has increased and therefore production and supply of coffee with excellent quality attach more significance. As a result, many coffee producing ... -
Sensitivity of microscopy compared to molecular diagnosis of p. Falciparum: implications on malaria treatment in epidemic areas in kenya
(2011)Detection of Plasmodium species by microscopy has been the gold standard for diagnosis of malaria for more than a century. Despite the fact that there is a significant decline in the number of positive cases reported from ... -
Shifting focus from external to in situ organic resources The redesign of four tropical long-term experiments
(UoEM, 2024-07)Long-term experiments (LTEs) are critical for evaluating strategies that can maintain or increase crop yields, soil fertility and soil organic carbon (SOC), and help adapt to climate change. Yet, scientific knowledge is ... -
Soil Greenhouse Gas Fluxes From Maize Production Under Different Soil Fertility Management Practices in East Africa
(2020-06)In sub-Saharan Africa (SSA), few studies have quantified greenhouse gas (GHG) emissions following application of soil amendments, for development of accurate national GHG inventories. Therefore, this study quantified soil ... -
Soil Inorganic N and N Uptake by Maize Following Application of Legume Biomass, Tithonia, Manure and Mineral Fertilizer in Central Kenya
(Springer Netherlands, 2011-05)In the smallholder farms of central Kenya soils suffer from nitrogen (N) deficiency due to inability to replenish it through application of chemical fertilizers and/or manure. This study evaluated the effect of some ... -
Specific Energy Consumption of Onion Slices During Hot-air Convection, Infrared Radiation and Combined Infrared-Convection Drying
(AENSI Journals, 2014)Total energy requirement and specific energy consumption for drying of onion slices were evaluated using various drying methods including hot-air convection, infrared radiation and hot air convection-infrared combination ... -
A study of yield characteristics during mechanical oil extraction of preheated and ground soybeans
(2007)Abstract: Soybeans were extracted for oil by compressing a ground sample at various operating pressures, pressing durations and product bulk temperatures. The oil yield from the various operations was measured and expressed ... -

Tied-ridging and soil inputs enhance small-scale maize productivity and profitability under erratic rainfall conditions in central Kenya
(UoEM, 2023)Deficits in soil moisture and low soil fertility are the major constraints to smallholder farming systems in the SSA (sub-Saharan Africa) region. This study evaluated the effects of tied ridging and selected soil fertility ... -
Tracking the Expression of Photosensitive Genic Male Sterility Gene in Rice
(2013-09)Photoperiod sensitive genic male sterile rice lines contain genes that induce complete male sterility in high temperature and long day light length period, but are male fertile under low temperature ... -
Tracking the expression of photosensitive genic male sterility genes in rice
(Academic Journals, 2013-11)Photoperiod sensitive genic male sterile rice lines contain genes that induce complete sterility in high temperature and long day light length period, and revert to fertility in optimum low temperature and short day light ... -
Trait matching of flower visitors and crops predicts fruit set better than trait diversity
(Wiley Online Library, 2015)Summary Understanding the relationships between trait diversity, species diversity and ecosystem functioning is essential for sustainable management. For functions comprising two trophic levels, trait matching between ... -
The Utility of Aerial Pan-Trapping for Assessing Insect Pollinators Across Vertical Strata
(2011)Insect pollinators provide a critical ecosystem service by pollinating many wild flowers and crops. It is therefore essential to be able to effectively survey and monitor pollinator communities across a range of habitats, ...
