Modeling integrated soil fertility management for maize production in Kenya using a Bayesian calibration of the DayCent model.
(UoEm, 2024-07-04)Sustainable intensification schemes such as integrated soil fertility management (ISFM) are a proposed strategy to close yield gaps, increase soil fertility, and achieve food security in sub-Saharan Africa. Biogeochemical ... -
QTL mapping for pod quality and yield traits in snap bean (Phaseolus vulgaris L.)
(UoEm, 2024-08-12)Pod quality and yield traits in snap bean (Phaseolus vulgaris L.) influence consumer preferences, crop adoption by farmers, and the ability of the product to be commercially competitive locally and globally. The objective ... -
A Diallel Cross-Based Analysis of the Genetic Basis of Pod Quality and Pod Yield in Snap Bean
(UoEm, 2024-07-27)Snap bean (Phaseolus vulgaris L.) is among the leading vegetables in Kenya that is mainly grown for export with the potential to increase household income. There are few programs in Kenya that focus on breeding new ... -
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, ... -
Efficacy of Metarhizium anisopliae against the Greater Pumpkin Fly Dacus bivitattus
(UoEm, 2023-07-01)The greater pumpkin fly Dacus bivittatus (Bigot) is a fruit fly indigenous to Africa, which causes extensive damage to Cucurbitaceae. To control this pest, farmers rely on synthetic chemicals, often organophosphates, which ... -
A Guide for Soil Health and Fertility for Maize production in Kenya
(UoEm, 2023)The health of your soil is a fundamental aspect of successful farming. However, many arable soils in Kenya have degraded and lost fertility over recent decades1. This is expected because many soils were recently transformed ... -
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, ... -
Determinants for rainwater harvesting adoption: a case study of smallholder farmers in Murang’a County, Kenya
(UoEm, 2024-05-17)Rainwater harvesting has been practiced among smallholder farmers for centuries in many parts of the world. Recently, it has gained more attention due to the reported increasing water demand and the need for sustainable ... -
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 ... -
Garden Project Bears Fruit in School Display
(UoEm, 2023-11-11)Pine Bluff Junior High School recently displayed its garden during a visit by Karleah Harris, assistant professor for the Department of Human Sciences at the University of Arkansas at Pine Bluff, along with UAPB alumni and ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
Evaluating the surface functional groups on banana leaf petioles and the resultant biochar for potential adsorbance
