Purpose This study aims to investigate the genetic background of performance sensitivity to climate variation in Bonga and Menz sheep, with the goal of improving the efficiency and sustainability of sheep production under variable climate conditions. Design/methodology/approach T...

Evaluation of Integrated Soil and Water Conservation Measures on Soil Properties, Soil Loss and Maize Production in Western Hararghe Zone, Oromia, Ethiopia

This study evaluated the effects of integrated biophysical soil and water conservation (SWC) measures on soil properties, soil loss and maize yield in Daro Lebu district, West Hararghe zone, from 2020 to 2022. The experiment arranged in a randomized complete block design (RCBD) w...

Optimizing Spatial Arrangement and Variety Selection for Sustainable Maize–Common Bean Intercropping in Eastern Ethiopia

Addressing food security in land-constrained regions requires sustainable intensification practices. This study evaluated the effects of spatial arrangement and bean variety selection on productivity and economic returns of maize–common bean intercropping in East Hararghe, Ethiop...

Gene editing applications, opportunities and challenges for crop improvement in Africa a review

Gene editing, particularly CRISPR/Cas-based new genomic techniques (NGTs), offers significant opportunities for accelerated crop improvement in developing African countries, ensuring food security, livelihoods, climate resilience, and economic growth. This review critically evalu...

Spatio-temporal dynamics of phytoplankton community in relation to environmental variables in Lake Maybar, Ethiopia

This study investigated the spatiotemporal dynamics of phytoplankton communities and physicochemical water quality parameters in Lake Maybar across seasonal variations. Sampling was conducted from 2023 to 2025 at three sites to evaluate phytoplankton composition, abundance, and b...

Heavy metal levels in crop and livestock product in Ethiopia: a review

Heavy metal contamination in food is a growing public health concern due to its potential for chronic toxicity. In Ethiopia, several studies have reported elevated levels of heavy metals in cereals, vegetables, fruits, milk, and fish across different regions, particularly in indu...

The effect of drought on physiological and agronomic traits of tef [Eragrostis tef (Zucc.) Trotter]

Increased intensity and duration of drought as a consequence of global warming is resulting in increased crop failure and food insecurity. This is particularly prevalent in regions where agriculture is rain fed, as the resultant water deficit in crop tissues as a consequence of i...

Review on Epidemiology of Sheep Pox and Goat Pox in Ethiopia

This review summarizes the epidemiology, clinical characteristics, transmission, diagnosis, treatment, prevention and control of sheep pox and goat pox (SGP), with particular emphasis on Ethiopia. It synthesizes available evidence on disease occurrence, risk factors, transmission...

Effect of NPS and Urea Fertilizer Rates on Phenology, Growth and Yield Components of Bread Wheat (Triticum Aestivum L.) in West Guji Southern Oromia

Bread wheat ( Triticum aestivum L.) is one of the major food crops cultivated in West Guji and plays a significant role in ensuring food security in Ethiopia. However, low soil fertility and inadequate fertilizer application are among the major constraints limiting wheat producti...

Genotype × environment interaction and yield stability of food barley (Hordeum vulgare L.) varieties using AMMI and GGE biplot models

Abstract Background Barley is a crucial crop worldwide, but it faces significant production challenges due to limited adaptable varieties, poor management practices, and environmental factors. Food barley varieties often struggle in unfamiliar environments, leading to crop loss....

Postbiotics in functional foods: Emerging bioactive metabolites, mechanisms of action, gut microbiome modulation, and health benefits: A review

Postbiotics are preparations of inanimate microorganisms and/or their components that confer a health benefit on the host, as defined by the International Scientific Association for Probiotics and Prebiotics (ISAPP). They have emerged as a distinct category of functional food ing...

Integrated metabolomic and proteomic profiling reveals density-dependent variation in development and chemical composition of queen bee larvae

Queen bee larvae (QBL), a byproduct of royal jelly production, are gaining prominence as a functional food due to their health-promoting effects. Beekeepers routinely adjust queen cell numbers per colony to maximize the yield of royal jelly during commercial production, yet the i...

Collateral damage of the EU deforestation regulation on commodity supply chains in cocoa, coffee, palm oil, soy, and cattle value chains

The European Union Deforestation Regulation (EUDR), formally adopted as Regulation (EU) 2023/1115, seeks to reduce global deforestation by requiring deforestation-free and legally compliant supply chains for commodities including cocoa, coffee, palm oil, soy, cattle, wood, and ru...

Survey on the distribution and epidemiology of faba bean gall (Physoderma viciae) in South Wollo, North-Eastern Ethiopia: an emerging threat to faba bean production

Faba bean gall, a disease caused by Physoderma viciae, has emerged as a major constraint to faba bean production in the highland areas of northeastern Ethiopia. This study assessed the prevalence, incidence, and severity of faba bean gall across major faba bean-growing districts...

Multivariate analysis of urban agriculture farming system practices as a fresh food source for urban residents in Jinka town, southern Ethiopia
