Evaluation of different fertilizer sources for sustainable carrot production in Tehuledere district, northern Ethiopia.

The demand for organic agriculture has been growing due to concerns about the environmental and health impacts of chemical-intensive farming. The study aimed to investigate the effects organic fertilizers on carrot (Nantes) growth and yield in Tehuledere district. The experiment was conducted at two sites (Gobeya and Libannos) using four fertilizer types (vermicompost, conventional compost, mixture of the two, and inorganic fertilizer) and a control.

Harnessing genome-wide genetic diversity, population structure and linkage disequilibrium in Ethiopian durum wheat gene pool.

Yanyang Liu, Henan Academy of Agricultural Sciences (HNAAS), China; Landraces are an important genetic source for transferring valuable novel genes and alleles required to enhance genetic variation. Therefore, information on the gene pool's genetic diversity and population structure is essential for the conservation and sustainable use of durum wheat genetic resources. Hence, the aim of this study was to assess genetic diversity, population structure, and linkage disequilibrium, as well as to identify regions with selection signature.

Marker-trait association analyses revealed major novel QTLs for grain yield and related traits in durum wheat.

The growing global demand for wheat for food is rising due to the influence of population growth and climate change. The dissection of complex traits by employing a genome-wide association study (GWAS) allows the identification of DNA markers associated with complex traits to improve the productivity of crops. We used GWAS with 10,045 single nucleotide polymorphism (SNP) markers to search for genomic regions associated with grain yield and related traits based on diverse panels of Ethiopian durum wheat.

Multivariate analyses of Ethiopian durum wheat revealed stable and high yielding genotypes.

Improving crop adaptation and stability across diverse and changing environmental conditions is essential to increasing grain yield per unit area. In turn, this contributes to meeting the increasing global food demand. Nevertheless, a number of factors challenge the efficiency of crop improvement programs, of which genotype-by-environment interaction (GEI) is one of the major factors.

COVID-19 knowledge, attitude and frequent hand hygiene practices among taxi drivers and associated factors in urban areas of Ethiopia.

Background: Although several studies have been conducted on COVID-19 knowledge, attitude and prevention practices among healthcare workers and the general population, there has not been any study among taxi drivers in Ethiopia, including Dessie City and Kombolcha Town, the lack of which hinders providing evidence-based interventions to this target group. Thus, this study was designed to contribute to proper planning of COVID-19 intervention measures among taxi drivers in Dessie City and Kombolcha Town, Ethiopia.

Methods: A cross-sectional study was conducted among 417 taxi drivers in Dessie City and Kombolcha Town during July to August, 2020.
