Programmed cell death-like behavior in photoperiod-sensitive genic male sterile (PGMS) rice
(Academic Journals, 2011-04)In photoperiod-sensitive genic male sterile rice (Oryza sativa L.) pollen abort in long day and high temperature, and revert to fertility in short day length and low temperature growth conditions. This type of control of ... -
Proximity to Woodland and Landscape Structure Drives Pollinator Visitation in Apple Orchard Ecosystem
(Crossmark, 2016-04)Landscapes of farms and adjacent areas are known to influence abundance of various arthropods such as pollinators in commercial agricultural ecosystems. In this context, we examined the effect of heterogeneous landscapes ... -
Public perceptions towards genetically modified crops and foods in Kenya
(2009)The broad objective of the study was to assess public perception towards Genetically Modified (GM) Crops and Foods in Kenya. The specific objectives were to find out the influence of background factors and Agro-ecological ... -
Quantitative trait loci (QTL) mapping of resistance to coffee berry disease (Colletotrichum kahawae Waller & Bridge) in Coffea arabica L. variety Rume Sudan
(Academic Journals, 2020-06)Coffee Berry Disease (CBD) is a major constraint that limits Coffea arabica production, whose resistance is governed by three genes, T, R that are dominant and recessive k in varieties Hibrido de Timor (HDT), Rume Sudan ... -
Research trends in modeling, optimization and control of the drying operation
(2007)Drying food is an extremely sensitive operation that requires the proper monitoring and control of the heating medium temperature as well as the length of time that the product is exposed to this temperature. Since the ... -
Resistance to Pythium root rot and anthracnose among Kenyan common bean genotypes and marker-assisted introgression of resistance genes
(Taylor and Francis, 2022-12)ABSTRACT Common bean (Phaseolus vulgaris L.) is an important food legume crop and major protein source in Kenya and many parts of the world. However, the yields are low due to the diseases like anthracnose caused by ... -
Response of French Bean {Phaseolus vulgaris L.) to Intra-row Spacing in Maseno Division, Kenya
(Asian Network for Scientific Information, 2012)The objective of this study was to evaluate the effect of intra-row spacing on growth of French bean (Phaseolus vulgaris L.) in Maseno Division, Kenya. The study was carried out at Maseno University Horticultural Farm. ... -
Restoring soil nutrient stocks using local inputs, tillage and sorghum-green gram intercropping strategies for drylands in Eastern Kenya
(UoEm, 2023)Soil macronutrient and micronutrient availability is particularly critical in semi-arid agro- ecological zones that are characterized by poor soil fertility and low rainfall regimes. An experiment was initiated in S ... -
Rosemary (Rosmarinus officinalis L.) growth rate, oil yield and oil quality under differing soil amendments
(Heliyon, 2022)In this work, we examined the influence of different soil amendments namely cow manure alone (Cm), cow manure plus fertilizer (Cm þ F), fertilizer alone (F) and unamended check, control on rosemary growth rate, fat content, ... -
Sahiwal cattle in semi-arid Kenya: genetic aspects of growth and survival traits and their relationship to milk production and fertility
(2011-12)The aim of this study was to estimate genetic and phenotypic parameters for growth and survival traits of Sahiwal cattle in Kenya and determine their relationship to milk production and fertility. Performance records of ... -
Screening for Water Deficit Tolerance, Relative Growth Analysis and Agrobacterium-Infectivity in Tropical Maize [Zea Mays L.] Inbred Lines in Nairobi, Kenya
(2014-10)The gap between maize demand and regional supply is increasing as small-holder farmers grapple with many challenges, key among them drought. Research in identifying maize lines that are tolerant to water deficit and that ... -

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 ... -
