Effect of salinity on seed germination of some tomato (Lycopersicon esculentum Mill.) varieties

Salinity adversely affects 20-30% of the irrigated area in the world. Tomato is sensitive to salinity. It is one of the most severe abiotic factors of many agricultural crops and it becoming the main problem in Ethiopia. This study was conducted to evaluate the effects of different salinity levels on the seed germination parameters of tomato varieties. It was laid out in a completely randomized design with three replicates. The treatment included four tomato varieties (Sirinka, Weyno, ARP D2, and Roma VF) and five salinity levels (1 dS m-1, 2 dS m-1, 3 dS m-1, 4 dS m-1, and control). Fifty seeds were placed in a Petri dish over a moistened germination paper for germination and seedlings and allowed to grow for 14 days. The germination rate, speed and energy of tomato seeds were significantly (p < 0.001) affected by the combined effect of variety and salinity. The shortest mean germination time, the highest mean germination rate, and the highest speed of germination were recorded in the ARP D2 variety in the control treatment. The lowest first and last days of germination, and the uncertainty of germination were recorded from ARP D2. However, an increase in the days of germination and in the uncertainty of germination, and a decrease in the germination index and total germination percentage trends were observed with increasing salinity levels. The highest level of salinity (4 dS m-1) affected the germination of tomato varieties. Among the four tested tomato varieties, ARP D2 and Roma VF were tolerant to salinity

Health care providers' awareness of breastfeeding practice recommendations during COVID-19 pandemic and associated factors in Northwest Ethiopia, 2021: A multicenter study.

BackgroundPrevention of coronavirus disease 2019 (COVID-19) transmission to newborns is one of the basic components of perinatal care in the era of the COVID-19 pandemic. As such, scientific evidence is compulsory for evidence-based practices. However, there was a scarcity of evidence on health care providers' awareness of breastfeeding practice recommendations during the COVID-19 pandemic in Ethiopia, particularly in the study setting.ObjectiveThe study aimed at assessing healthcare providers' awareness of breastfeeding practice recommendations during the COVID-19 pandemic and associated factors among healthcare providers in northwest Ethiopia, 2021.MethodsA multicenter cross-sectional study was conducted among 405 healthcare providers working in hospitals of Gondar province from November 15, 2020, to March 10, 2021. A simple random sampling technique was employed to select the study subjects. Data were collected via a structured-self-administered questionnaire. EPI INFO version 7.1.2 and SPSS version 25 were used for data entry and analysis respectively. Binary logistic regression analyses were done to identify associated factors and the adjusted odds ratio (AOR) with its 95% confidence interval (CI) at a p-value of ResultsThe healthcare providers' awareness of breastfeeding practice recommendations during the COVID-19 pandemic was 40.7% (95% CI: 35.9, 45.6). Working in a tertiary hospital (AOR = 3.69; 95% CI: 2.24, 6.08), using COVID-19 guideline updates (AOR = 3.34; 95% CI: 2.1, 5.3), being trained on COVID-19 (AOR = 2.78; 95% CI: 1.74, 4.47), owning a smartphone and/or a computer (AOR = 2.26; 95% CI: 1.39, 3.68), and perceiving that COVID-19 is dangerous (AOR = 1.78; 95% CI: 1.05, 3.01) were factors positively associated with healthcare providers' awareness of breastfeeding practice recommendations during the pandemic of COVID-19.ConclusionOnly two in five healthcare providers were aware of recommendations on breastfeeding practice during the COVID-19 pandemic and related to information of accessibility information on COVID-19. Therefore, expanding COVID-19 related information through the provision of COVID-19 training and guidelines to all levels of hospitals would improve health care providers' awareness of breastfeeding practice recommendations amid the COVID-19 pandemic

Effect of planting time on growth, yield components, seed yield and quality of onion (Allium cepa L.) at Tehuledere district, northeastern Ethiopia

Abstract Background Onion (Allium cepa L.) is member of the family Alliaceae and the most widely grown herbaceous biennial vegetable crop. Quality planting material is one of the major inputs to successful vegetable production. However, it is one of the major constraints in Ethiopia. Northeastern Ethiopia has suitable agro-climatic condition for onion seed production. However, onion seed production packages, including its appropriate planting time, are not yet determined. Evidences on effects of the different planting time on quality and yield level are not well explored. Therefore, this experiment was conducted at Jari small-scale irrigation scheme from September 2015 to April 2016 to determine an appropriate planting time for a better plant growth, yield components, seed yield and quality of Adama red onion variety. Methods The experiment was laid out in randomized complete block design with three replications. Treatments were nine planting dates: September 1st, September 16th, October 1st, October 16th, October 31st, November 15th, November 30th, December 15th and December 30th. Data were collected on growth, yield components, seed yield and quality parameters and analyzed using SAS version 9.2 statistical software. Results Analysis of variance revealed that plant height, number of leaves per plant, number of scapes per plant, scape diameter, scape height, days to 50% flowering and maturity, umbel diameter, number of seeds per umbel, 1000-seed weight, seed yield and germination percentage were significantly influenced by planting time. The highest seed yield (1032.7 kg/ha) and the highest germination percentage (94.3%) were recorded from bulbs planted early (September 1st). On the other hand, the lowest seed yield (29.7 kg/ha) and germination percentage (15.3%) recorded from bulb planted late (December). The correlation values explain the apparent association of the planting time parameters with each other and clearly indicated the magnitude and directions of the association and relationships. Conclusion The September 1st is recommended as appropriate planting time for onion seed production at Jari, northeastern Ethiopia

The role of nutrition‐sensitive agriculture combined with behavioral interventions in childhood growth in Ethiopia: An adequacy evaluation study

Abstract Objective The study aimed to investigate the role of nutrition‐sensitive and specific interventions along with nutrition education on child stunting during the first 1000 days in Ethiopia. Methods An adequacy evaluation study was used to see changes between the baseline and end‐line data after following for 1 year. A sample of 170 mother‐child pairs who had a 1‐year followed up was used to detect differences. We performed structural equation modeling to elucidate changes in feeding behaviors, socioeconomic status, water, sanitation and hygiene on child linear growth. Furthermore, the independent effect of covariates on child linear growth was handled using a general linear model. Results A total of 170 and 270 mother‐child dyads were interviewed at baseline and end‐line surveys, respectively. After about 1 year of intervention, the annual rate of stunting prevalence declined from 29.3% (95% confidence interval [CI] = 18.6, 42.7) to 16.4% (95% CI = 10.7, 24.2). There was a significant change in the mean of length‐for‐age Z‐score which changed from −1.18 to −0.45 (P < .034). Adjusting for the different constructs of the health belief model, child sex, age, feeding behaviors, and dietary diversity, one egg consumption per day was responsible for the most significant variability explained (36%) for stunting reduction. Conclusions Sustainable access to egg consumption for children below 2 years experienced a substantial reduction in childhood stunting. A combination of nutrition‐sensitive agricultural and direct nutrition interventions along with behavioral‐based education is a sustainable strategy in reducing and preventing child growth from faltering in the early life stages

Dietary diversity and associated factors among lactating women in Ethiopia: Cross sectional study

Introduction: Lactating women are more vulnerable to malnutrition due to increased physiological demands, the lactogenesis process, consuming an undiversified monotonous diet, and increased nutrient needs during lactation. However, meeting minimum standards of dietary diversity for lactating mothers is a challenge in many developing countries, including Ethiopia. As a result, the purpose of this study was to evaluate dietary diversity and associated factors among breastfeeding mothers. Method: A community-based cross-sectional study was conducted. A multistage sampling technique was used to get a total of 665 lactating mothers from their kebeles. Face-to-face interviews with a structured questionnaire were used to collect data. Data was entered into Epidata version 3.1 and exported to the Statistical Package for the Social Sciences version 23.0 for analysis. Bivariate and multivariable logistic regression models were used to identify the important predictors of maternal dietary diversity. Variables having p < 0.25 in bivariate analysis were fitted to multivariate analysis. The odds ratio, P-value < 0.05, and 95% CI were computed to show the association of variables. Result: A total of 665 lactating women participated, with a response rate of 96.2%. Only 163 (24.5 %) mothers satisfied the minimal dietary diversity criteria. Mothers' dietary diversity was significantly associated with their education status [AOR 5.173 (2.132–12.552)], head of household [AOR 3.822 (2.290–6.378)], family size [AOR 5.358 (2.838–10.116)], and meal frequency [AOR 3.379 (1.789–6.380). Conclusion: One in every four mothers met the dietary diversity standard. Concerned bodies should consider ensuring large-scale interventions that focus on the identified factors to improve dietary diversity practices

SARS-CoV-2 vaccination modelling for safe surgery to save lives: data from an international prospective cohort study

Background Preoperative SARS-CoV-2 vaccination could support safer elective surgery. Vaccine numbers are limited so this study aimed to inform their prioritization by modelling. Methods The primary outcome was the number needed to vaccinate (NNV) to prevent one COVID-19-related death in 1 year. NNVs were based on postoperative SARS-CoV-2 rates and mortality in an international cohort study (surgical patients), and community SARS-CoV-2 incidence and case fatality data (general population). NNV estimates were stratified by age (18-49, 50-69, 70 or more years) and type of surgery. Best- and worst-case scenarios were used to describe uncertainty. Results NNVs were more favourable in surgical patients than the general population. The most favourable NNVs were in patients aged 70 years or more needing cancer surgery (351; best case 196, worst case 816) or non-cancer surgery (733; best case 407, worst case 1664). Both exceeded the NNV in the general population (1840; best case 1196, worst case 3066). NNVs for surgical patients remained favourable at a range of SARS-CoV-2 incidence rates in sensitivity analysis modelling. Globally, prioritizing preoperative vaccination of patients needing elective surgery ahead of the general population could prevent an additional 58 687 (best case 115 007, worst case 20 177) COVID-19-related deaths in 1 year. Conclusion As global roll out of SARS-CoV-2 vaccination proceeds, patients needing elective surgery should be prioritized ahead of the general population.The aim of this study was to inform vaccination prioritization by modelling the impact of vaccination on elective inpatient surgery. The study found that patients aged at least 70 years needing elective surgery should be prioritized alongside other high-risk groups during early vaccination programmes. Once vaccines are rolled out to younger populations, prioritizing surgical patients is advantageous
