Harvesting nature's bounty: exploring the ethnobotanical landscape of wild edible plants in the Awi Agäw community, Northwestern Ethiopia

by Alemu Tsega and Belsti Atnkut

Journal of ethnobiology and ethnomedicine, May 30, 2024

Ethiopia boasts a great diversity of wild edible plant species (WEPS), but millions of its citizens still suffer from chronic hunger every year. In this context, we here document the use and conservation of WEPS in the Awi Agäw community, Northwestern Ethiopia. Methods We performed a cross-sectional study from October 2021 to June 2022. Ethnobotanical and conservation status data were collected via semi-structured interviews, focus group discussions, field walks and market surveys. A total of 374 respondents from three districts (Guangua, Jawi and Ankasha) were purposely selected for the study. Descriptive statistics, including preference rankings, frequencies and direct matrix rankings, were employed for the data analysis. Results We identified a total of 39 WEPS plant taxa distributed among 26 families and 32 genera. The Moraceae and Rosaceae had the greatest numbers of plants, with five and three species, respectively. The WEPS are regularly consumed in the study area to alleviate hunger. However, threats such as habitat loss, agricultural expansion, deforestation for firewood and other reasons, and pesticide use threaten WEPS availability. Conclusion Therefore, community-based conservation interventions need to be encouraged to safeguard WEPS and associated traditional knowledge. Furthermore, nutritional quality analysis is recommended for the selection of promising WEPS candidates.

Genotype-by-environment interaction and stability analysis of grain yield of bread wheat (Triticum aestivum L.) genotypes using AMMI and GGE biplot analyses

various environmental constraints and yield reduction associated with adaptation. To identify
adaptable genotypes, a total of 12 bread wheat genotypes (G1 to G12) were evaluated for their
genotype-environment interaction (GEI) and stability across three different environments for two
years using Additive Main Effect and Multiplicative Interaction (AMMI) and genotype main effect
plus genotype-by-environment interaction (GGE) biplots analysis. GEI is a common phenomenon
in crop improvement and is of significant importance in genotype assessment and recommendation. According to combined analysis of variance, grain yield was considerably impacted by
environments, genotypes, and GEI. AMMI and GGE biplots analysis also provided insights into the
performance and stability of the genotypes across diverse environmental conditions. Among the
12 genotypes, G6 was selected by AMMI biplot analysis as adaptive and high-yielding genotype;
G5 and G7 demonstrated high stability and minimal interaction with the environment, as evidenced by their IPCA1 values. G7 was identified as the most stable and high-yielding genotype.
The GGE biplot’s polygon view revealed that the highest grain yield was obtained from G6 in
environment three (E3). E3 was selected as the ideal environment by the GGE biplot. The top
three stable genotypes identified by AMMI stability value (ASV) were G5, G7, and G10, while the
most stable genotype determined by Genotype Selection Index (GSI) was G7. Even though G6 was
a high yielder, it was found to be unstable according to ASV and ranked third in stability according to GSI. Based on the study’s findings, the GGE biplot genotype view for grain yield
identified Tay genotype (G6) to be the most ideal genotype due to its high grain yield and stability
in diverse environments. G7 showed similar characteristics and was also stable. These findings
provide valuable insights to breeders and researchers for selecting high-yielding and stable, as
well as high-yielding specifically adapted genotypes.

It is a lifesaving practice for people who have lost ample volumes of blood as a result of accidents, obstetric and gynecological bleeding, severe anemia, and cancer. Aim: This study is aimed at assessing knowledge, attitude, practice, and associated factors toward voluntary blood donation in Chagni, Dangila, Injibara, and Jawi towns. Subject and Methods: A community-based cross-sectional study design and multistage sampling technique were employed. The data was analyzed using SPSS version 26. Both descriptive statistics and the multivariate logistic regression model were employed to determine the significance. The association between blood donation knowledge, attitude, practice, and sociodemographic variables was tested using multivariate logistic regression. Results: In Chagni, 110 (55.6%), Dangila, 162 (79.0%), Injibara, 139 (73.5%), and Jawi, 165 (64.5%), towns had adequate knowledge regarding voluntary blood donation. In Chagni, 141 (74.6%), Dangila, 170 (66.4%), Injibara, 168 (82.0%), and Jawi, 148 (74.7%), towns had an adequate attitude regarding voluntary blood donation. In Chagni, 28 (14.1%), Dangila (15.3%), Injibara (29.3%), and Jawi (12.3%), towns practiced voluntary blood donation. Respondents' sex, education level, and age were found to be significantly associated with knowledge, attitude, and practice of blood donation. Those who had a degree and above were more likely (AOR = 9 239, 5.789, 5.468, and 9.72 at 95% CI) to know about blood donation relative to those who could not read and write in Chagni, Dangila, Injibara, and Jawi, respectively. Conclusion: The majority of respondents had adequate knowledge and attitudes toward blood donation but had lower practices toward voluntary blood donation.

Evaluation of tomato (Lycopersicon Esculentum Miller) varieties for nematode and ralstonia diseases resistance and productivity

The objective of this study was to evaluate tomato varieties for nematode and Ralstonia diseases resistance and productivity. The experiment was conducted under a complete randomized design experiment with three replications at Hawassa University shade house. Four varieties of tomato were inoculated with nematode (Meloidogyne incognita), Ralstonia solanacearum and mixed bacteria (Bacillus subtilis, Pseudomonas) in single and in combination of them with a total of six treatments. The multivariate analysis of variance showed a signifi cant effect both for varieties and treatments for most yield and growth parameters except for unmarketable fruit yield per plant and weight of unmarketable fruit per plant. Tomato var. Venise produced the highest total yield (7556.33g) whereas Galilea variety gave the lowest total yield (2656.4g). Based on the yield performance, nematode and ralstonia resistance rating, Venise was found to be the best tomato variety followed by Awassa for disease resistance and productivity. Variety Galilea was severely affected by Meloidogyne incognita as well as by the Ralstonia solanacearum and produced the lowest marketable fruit percentage. None of the tomato varieties was found highly resistant (0 % disease severity) to Meloidogyne incognita and Ralstonia solanacearum. Therefore, there is a need to develop nematode and Ralstonia-resistant tomato varieties.
