Household's socio-economic factors influencing the level of adaptation to climate variability in the dry zones of Eastern Kenya
(Elsevier, 2015-11)Climate variability has a negative impact on crop productivity and has had an effect on many small-holder farmers in the arid and semi-arid lands (ASALs). Small-holder farmers in Eastern Kenya are faced with the constraint ... -
Humidity Control System for Wine Maturation Structures
(2013-12-13)Abstract. Fogging systems can be used to maintain the high humidity required in wine aging structures at acceptable levels during the day and as long as temperature inside the wine maturation store is rising. However, as ... -
Identification of Elsinoë phaseoli causing bean scab in Kenya and evaluation of sporulation using five adapted techniques
(UoEm, 2024-06-07)This research addresses the presence of Elsinoë phaseoli in Kenya, where information on the biology of this pathogen remains scarce. Employing a multifaceted approach, the study demonstrates the steps taken to isolate, ... -
Identifying Morpho-Physiological Characteristics Associated with Drought Tolerance in Selected Chikpea Germ Plasm in Nakuru and Baringo Counties, Kenya
(2013-11)This paper examines the morpho-physiological characteristics of chickpea associated with drought tolerance based on a study of selected chickpea lines under field conditions in Nakuru and Baringo counties in Kenya. Drought ... -
Identifying Morpho-Physiological Characteristics Associated with Drought Tolerance in Selected Chikpea Germ Plasm in Nakuru and Baringo Counties, Kenya
(2013-11)tolerance based on a study of selected chickpea lines under field conditions in Nakuru and Baringo counties in Kenya. Drought has been spreading to more land in Kenya over the years due to climatic change attributed to ... -
Impact of reduced tillage and crop residue management on soil properties and crop yields in a long-term trial in western Kenya
(2015-11)Sustainable farming practices are required to address the persistent problems of land degradation and declining crop productivity in sub-Saharan Africa (SSA). Approaches such as reducing tillage and retaining crop residues ... -
In Vitro Control ofPhytophthora infestans and Alternaria solani Using Crude Extracts and Essential Oils from Selected Plants
(Hindawi, 2020-07)Tomato production is constrained by fungal diseases especially the early and late blight caused by Alternaria solani and Phytophthora infestans, respectively. Control of the two diseases is usually by use of synthetic ... -
Inoculated Soybean Yields Response to Nitrogen and Phosphorus Application
(SCIENCEDOMAIN international, 2016)Inherent low soil nitrogen (N) and phosphorus (P) is one of the major hindrances of increased soybean productivity in Malawian soils. Although, inoculation of legumes with rhizobia, has been advocated for decades as a ... -
Inoculum sources and management of bean scab caused by Elsinoë phaseoli
(UoEm, 2024-06-24)Bean scab caused by Elsinoë phaseoli is a major challenge to common bean cultivationin Kenya. However, knowledge about its epidemiology and management is limited.This study conducted three experiments in Kakamega, Kenya, ... -
Integrated Soil Fertility and Water Management Practices for Enhanced Agricultural Productivity
(UoeM, 2023-06-23)Declining agricultural productivity has been a challenge worldwide and especially in Sub-Saharan Africa (SSA). Low agricultural productivity has been attributed to factors such as poor farm management practices, soil ... -
Inter-seasonal Effects on Selected Maturity Parameters of DK8031 Maize Grown under Varying Irrigation and Nitrogen Levels in Embu County, Kenya
(2017-07)Maize is a staple food and a source of carbohydrates to a large proportion of people in Kenya. The performance of crop plants such as maize depends on a number of factors such as climate, soil characteristics and plant ... -
Introgressing Photoperiod/Thermo-sensitive Genic Male Sterile Gene into Basmati 370 Rice
(UoEm, 2025-01-08)The emasculation of male gametes in pollen-recipient parents among self-pollinated crops (rice) is key to producing quality hybrid rice seeds. One of the emasculation tools in rice breeding is the photoperiodthermo sensitive ... -
