Abnormal uterine bleeding and its associated factors among reproductive-age women who visit the gynecology ward in Dilla University General Hospital, Southern Ethiopia, 2022

BackgroundAbnormal uterine bleeding, a frequent gynecological problem among women of reproductive age, significantly affects their health and quality of life. Despite its problem, research on its extent and contributing factors in Ethiopia is scarce. Hence, this study is designed to determine the magnitude and factors associated with abnormal uterine bleeding among women visiting Dilla University General Hospital, Dilla, Ethiopia.MethodsA cross-sectional study design was conducted with 380 women of reproductive age at Dilla University General Hospital. A systematic sampling method was employed to select the participants for the study. A structured interview administered questionnaire and checklist were used to collect the data. Stata V.14 software was used for cleaning, coding, ensuring completeness and accuracy, and further analysis. Bivariate and multivariable logistic regression analyses were used. Finally, the variables that have a p-value of < 0.05 were considered statistically significant.ResultsIn this study, the magnitude of abnormal uterine bleeding was 24.21% (95% CI, 20.14–28.79). History of sexually transmitted disease [AOR = 1.44, 95% CI: (1.33, 4.75)], history of anemia [AOR = 3.92, 95% CI: (1.20, 12.74)]., history of alcohol consumption [AOR = 2.49, 95% CI: (1.22, 5.06)], and perceived stress level [AOR = 1.30, 95% CI: (1.15, 1.69)] were found to be significantly associated with abnormal uterine bleeding.ConclusionsThe magnitude of abnormal uterine bleeding was 24.2% in the study setting. Factors such as a history of sexually transmitted disease, anemia, alcohol consumption, and perceived stress level were identified as significant risk factors for abnormal uterine bleeding. Addressing these factors is crucial for management. Further research and interventions targeting these risks are needed to enhance health outcomes. The study provides valuable insights for future interventions.

Workplace violence and its associated factors among nurses working in university teaching hospitals in Southern Ethiopia: a mixed approach

BackgroundWorkplace violence among nurses has increased dramatically in the last decade. Still, mitigation techniques have not been well explored; many studies used a quantitative research approach, and there is a knowledge gap on the current status of workplace violence. The aim of this study was to assess the prevalence of workplace violence and associated factors among nurses working at university teaching hospitals in the South Region of Ethiopia.MethodsAn institution-based cross-sectional study was conducted using a mixed approach. A random sample of 400 nurses was interviewed for the quantitative analysis, and nine key informants were interviewed for the qualitative analysis. Descriptive statistics were used to summarize the data. A logistic regression model was used to analyze the data. An adjusted odds ratio with a 95% confidence interval and a corresponding p-value &amp;lt; 0.05 was used to determine the association between variables. The qualitative data were transcribed and translated, then themes were created, followed by thematic analysis using Open Code version 4.02.ResultsThe prevalence of workplace violence was 61.3% within the last 12 months. Nurses working in emergency departments [AOR = 4.27, 95% CI: 2.21, 8.24], nurses working in inpatient departments [AOR = 2.58, 95% CI: 1.40, 4.72], the number of nurses in the same working unit from one to five [AOR = 2.36, 95% CI: 1.21, 4.63], and six to ten staff nurses [AOR = 2.12, 95% CI: 1.17, 3.85], nurses routinely making direct physical contact [AOR = 2.77, 95% CI: 1.55, 4.95], and nurses' work time between 6 pm and 7 am [AOR = 1.68, 95% CI: 1.00, 2.82] were factors significantly associated with workplace violence.ConclusionIn this study, the prevalence of workplace violence against nurses was high. We identified factors significantly associated with workplace violence among nurses. Interventions should focus on early risk identification, the management of violent incidents, and the establishment of violence protection strategies that consider contextual factors to reduce workplace violence.

Modelling Time to Recovery from Multidrug Resistant Tuberculosis in Southern Ethiopia

Introduction: Multidrug resistant tuberculosis (MDR-TB) is a global heath threat, resistant to key anti-TB drugs. It is ranked among the top 10 causes of death worldwide. Therefore, the current study investigated time to recovery from MDR-TB in southern Ethiopia. Data, Materials and Methods: Restrospective data from selected hospitals in SNNPR (January 2016 to December 2021) were analyzed. A cluster sample of 301 MDR-TB patients (131 NEMMCH, 121 BH, 49 AGH) was considered. Results: Among the 301 cases, 116 (38.5%) were censored. While 185 (61.5%) were recovered. Parametric shared frailty models were employed to account unobserved heterogeneity among the Hospitals and patients and AFT models were employed. the median recovery time of MDR-TB is 22 months. The clustering effect of frailty model was hospitals. Weibull-gamma shared frailty model was appropriate for this data. Conclusion: The final model showed that males have higher recovery rates than females. Extra pulmonary MDR-TB and Urban residency correleted with longer recovery times. The recovery rate increases with increasing baseline weight, education level, and occupation. But, the recovery rate decreases with smoking, co-morbidities, previous drug history, history of TB, and alcohol use Recommendation: All concerned bodies should be cognizant on the risk factors of MDR-TB in SNNP region By providing on early case detection and appropriate treatment of drug-susceptible MDR-TB, since it is essential to shorten the recovery time of MDR-TB patients in line with WHO guidelines

Prioritization of soil erosion-prone sub-watersheds using geomorphometric and statistical-based weighted sum priority approach in the middle Omo-Gibe River basin, Southern Ethiopia

ABSTRACT Soil erosion, a major factor contributing to land degradation, poses significant environmental challenges across sub-Saharan Africa, including Ethiopia. This study identifies erosion-prone sub-watersheds in southern Ethiopia's middle Omo-Gibe River basin using digital elevation model data, analyzed using a geomorphometric and statistically weighted sum priority approach in a Geographic Information System environment. Additionally, hypsometric analysis, lithology, land use/cover analysis, and field observations were integrated to enhance methodological reliability in assessing soil erosion patterns and subsequent land degradation in the basin. Results highlight sub-watersheds with varying degrees of erosion sensitivity, emphasizing morphometric parameters and landscape characteristics. Furthermore, hypsometric analysis confirms a moderate to high susceptibility of sub-watersheds to soil erosion. Moreover, half of the river basin consists of shrubland, encompassing scrubs, range lands, and small wooded areas. These are less efficient in mitigating erosion compared to forests, especially in the face of significant summer rainfall and ensuing runoff. Statistical prioritization identified 19 sub-watersheds, covering 43% of the basin's total area, as highly prone to soil erosion and land degradation. The study's findings are valuable for Ethiopian watershed management decision-makers, enabling informed resource allocation and targeted interventions to control soil erosion and protect water resources by utilizing the outputs of this study.

Self-care behavior and associated factors among adult heart failure patients in outpatient cardiac follow-up unit at Wachemo University Nigist Eleni Comprehensive Specialized Hospital, Southern Ethiopia

BackgroundHeart failure is a serious medical condition that occurs when the heart is unable to pump sufficient blood to meet the needs of the tissues. Good self-care is an essential behavior in long term management and maintenance of physiologic stability, better medical and person-centered outcomes. Poor self-care behavior deteriorates the outcomes of heart failure patients. However, there were no sufficient evidences that illustrate the topic in the country, including the study area.MethodologyInstitutional based cross-sectional study was conducted among 250 heart failure patients from July 5-August 4, 2021. All adult heart failure patients who fulfill the inclusion criteria and have appointment during study period were included in the study. Interview and medical chart review was used to collect data. Epidata version 3.1 and SPSS version 20 were used for data entry and analysis respectively. Bivariate and multivariable analysis was computed. The model fitness was checked by Hosmer and Lemeshow test.ResultsFrom the total patients, 240 were interviewed with the response rate of 96%. Among these, 140(58.3%) [95% CI: 52.6, 64.9] had poor self-care behavior. Age>54: 9.891 [2.228, 43.922], poor knowledge: 6.980[1.065, 45.727], depression: 4.973[1.107, 22.338], low social support: 6.060[1.373, 26.739], insomnia: 4.801[1.019, 22.622] and duration with heart failure <1 year: 5.782[1.438, 23.247] were factors associated with poor self-care behavior.ConclusionIn this study, more than half of participants attending at Wachemo University Nigist Eleni Comprehensive Specialized Hospital in outpatient cardiac follow-up unit had poor self-care behavior. Of the study variables, older age, poor knowledge, depressive symptoms, low social support, insomnia and short duration with heart failure were related with poor self-care behavior. Thus, the findings highlight importance of assessing level of self-care behavior and implicate direction to take action to enhance level of self-care behavior.

Early warning signals of the termination of the African Humid Period(s)

The transition from a humid green Sahara to today’s hyperarid conditions in northern Africa ~5.5 thousand years ago shows the dramatic environmental change to which human societies were exposed and had to adapt to. In this work, we show that in the 620,000-year environmental record from the Chew Bahir basin in the southern Ethiopian Rift, with its decadal resolution, this one thousand year long transition is particularly well documented, along with 20–80 year long droughts, recurring every ~160 years, as possible early warnings. Together with events of extreme wetness at the end of the transition, these droughts form a pronounced climate “flickering”, which can be simulated in climate models and is also present in earlier climate transitions in the Chew Bahir environmental record, indicating that transitions with flickering are characteristic of this region.

Determinants of urban households in the diversification of livelihood activities: The case of Wolaita zone in southern Ethiopia

Diversification of Livelihood Activities (DLA) is indeed crucial for populous countries like Ethiopia, where it serves as a strategy to mitigate food insecurity. Despite its significance, empirical studies focusing on DLA among urban households in Ethiopia are relatively scarce. Therefore, this study examines factors affecting urban households' participation in the DLA in selected towns of the Wolaita zone. The study used both primary and secondary data. A total of 310 sample respondents from three town administrations in the Wolaita zone: Areka, Boditi, and Sodo, were selected using a multi-phase sampling technique. The study used a survey questionnaire, Key Informant Interviews, Focus Group Discussions, and observations as methods for primary data collection. The collected data was analyzed using descriptive and inferential statistics. The results revealed that among the sampled respondents, 23.9 %, 28.4 %, and 33.2 % depend on on-farm, on-farm + non-farm, non-farm + off-farm activities, respectively, while the remaining 14.5 % diversify their livelihood activities through combinations of on-farm + non-farm + off-farm Livelihood Diversification Activities (LDA). The Multinomial Logot (MNL) model result shows that the participation of LDA in the study areas was positively and negatively determined by cooperative membership, development agent training, gender, education, home ownership, rural connections, household income, and technical skills that were found to be statistically significant at 1 %, 5 %, and 10 %. Therefore, the government should prioritize empowering the diversification of livelihood activities and develop policies and programs that support urban households’ livelihoods, with a specific focus on promoting off-farm and non-farm endeavors.

Early Postnatal Care Utilization and Associated Factors Among Women Who Give Birth in the Last Six Weeks in Hosanna Town, Southern Ethiopia, 2022.

Background: The early postnatal period is defined as the first 48 h to 7 days after delivery. The early postnatal visit is especially the most critical time for the survival of mothers and newborns, particularly through early detection and management of postpartum complications. Despite the benefits, most mothers and newborns do not receive early postnatal care services from healthcare providers during the critical first few days after delivery. Objectives: This study is aimed at assessing the prevalence of early postnatal care utilization and associated factors among mothers who gave birth within the last 6 weeks in Hosanna town, Southern Ethiopia, from April 20 to May 30, 2022. Method: A community-based cross-sectional study was conducted in Hadiya Zone, Hosanna town, Southern Ethiopia. A simple random sample technique was used to recruit 403 mothers who had given birth in the previous 6 weeks from a family folder. Data was collected through face-to-face interviews using a standardized questionnaire. Binary logistic regression was used to assess the association between outcomes and explanatory variables, and the strength of the association was interpreted using an odds ratio with a 95% confidence interval. In our study, p values of 0.05 were considered statistically significant. Results: The prevalence of early postnatal care utilization among mothers who gave birth within 1 week of the study area was 25.8% (95% CI: 21.7-30.0). No formal and primary educational level of husband (AOR = 0.05, 95% CI: [0.02, 0.16]), antenatal care follow-up (AOR = 2.13, 95% CI: [1.11, 4.1]), length of hospital stay before discharge (≥24 h) (AOR = 0.3, 95% CI: [0.16, 0.55]), and information about early postnatal care utilization (AOR = 3.08, 95% CI: [1.72, 5.52]) were factors significantly associated with early postnatal care utilization. Conclusion: In comparison to World Health Organization standards, the study's overall prevalence of early postnatal care utilization was low. Early postnatal care use was significantly associated with antenatal care follow-up, the husband's educational level, knowledge of early postnatal care use, and length of stay at the health institution following birth. As a result, the strength of health facilities is to improve service provision, information education, and communication.

The abundance and distribution of sandflies (with emphasis on Phlebotomus pedifer) (Diptera: Psychodidae) along the altitudinal gradient in Kindo Didaye district, Wolaita Zone, South Ethiopia.

Understanding the distribution patterns of medically significant sandflies is crucial for effective vector and disease control planning. This study focused on investigating the abundance and distribution of phlebotomine sandflies, specifically emphasizing Phlebotomus pedifer (Diptera: Psychodidae), the vector of Leishmania aethiopica responsible for cutaneous leishmaniasis in the highlands of southern Ethiopia. The study employed CDC light traps and sticky paper traps in various habitats, including human houses, farm fields, and rock cliffs, with and without the presence of hyraxes. The study was conducted along an altitudinal gradient in Kindo Didaye district, Wolaita Zone. A total of 7,994 sandflies belonging to 2 genera, Phlebotomus (26.1%) and Sergentomyia (73.9%), were collected. In the genus Phlebotomus, P. pedifer (74.1%) was the most abundant, followed by P. alexandri (18.05%) and P. gibiensis (7.85%). Altitude showed a strong positive association with the density and distribution of P. pedifer and a negative association with those of P. alexandri, P. gibiensis, and Sergentomyia spp. Furthermore, the study revealed distinct habitat preferences, with P. pedifer showing the highest mean density in hyrax dwellings, followed by human houses, and the lowest in farm fields. These findings provide valuable insights for planning targeted control measures against P. pedifer in both indoor and outdoor environments, particularly in the highland and midland areas of the study region.

Determinants of cardiovascular disease among type 2 diabetic patients attending diabetic follow-up clinic in Arba Minch general hospital, southern Ethiopia: an unmatched case-control study.

Cardiovascular disease (CVD) is a major cause of death and disability among patients with type 2 diabetes, especially in low-income and middle-income countries. Type 2 diabetes mellitus (T2DM) patients have a 2-4-fold increased risk of CVD. There is limited data about cardiovascular disease risks and its determinants among T2DM patients in Ethiopia. This study aimed to identify possible predictors of cardiovascular diseases among adults with T2DM in southern Ethiopia. A hospital-based unmatched case-control study was conducted at southern Ethiopia Arbaminch Hospital on 196 randomly selected patients with type 2 diabetes on follow-up (98 cases and 98 controls). The authors collected data using a structured interviewer-administered questionnaire, laboratory checklist, and additional document review of T2DM patients. A multivariable binary logistic regression was fitted to identify cardiovascular disease determinants, and the findings were presented using an adjusted odds ratio (AOR) with a 95% CI. The mean reported age (±SD) of the cases and the controls was 56.3.3 (±8.9) and 52.3 (±9.3) years, respectively. The two identified independent determinants of cardiovascular disease with AOR [95% CI] were hypertension [AOR=4.953, 95% CI (2.47, 9.93) and persistent urine albuminuria [AOR=12.9, 95% CI (3.98, 41.7)]. This study showed that having high blood pressure and persistent urine albuminuria are independent predictors of cardiovascular disease in T2DM patients. The current study setting needs an intervention for mitigating these cardiovascular disease determinants.

Evaluating the impacts of climate-induced east Africa's recent disastrous drought on the pastoral livelihoods

Recurrent droughts, exacerbated by the climate, are becoming the greatest threat to the people of eastern Africa. Eastern Ethiopia, as part of this region, is most affected by droughts and other climate-related shocks, as people there live mainly from pastoralism. In this region urgent action is needed to reduce extreme vulnerability and increase adaptive capacity. To bring about change, the development of proactive drought risk management and the adoption of appropriate measures are urgently demanded. In order to take take informed development actions, it is essential to identify the underlying problems and provide direction but few studies exist to date. Accordingly, this study was conducted to investigate the impact of the recent climate-induced drought disaster on pastoralists’ livelihoods and the socio-economic determinants of pastoralists’ vulnerability in southern Ethiopia. Mixed, positivist and post-positivist research approaches were used in the design of the study. Both random and purposive sampling procedures were used in this study to select the study sites and respondents or discussants. A questionnaire was used to collect objective data from the randomly selected 371 respondents, while focus group discussions, key informant interviews and observations were used as methods to collect subjective data. While objective data was collected using semi-structured questions, subjective data was collected were using unstructured or open-ended questions. Descriptive statistics were used to analyze the objective data, while the subjective data was analyzed using stepwise content analysis. The result shows that severe drought was the most important extreme episode in the area. In addition, the low adaptive capacity (0.29) combined with the high sensitivity (0.41) and exposure factors (0.36) indicate that pastoralists are highly vulnerable (0.49) to climate-related impacts. The index for catastrophic risk of drought episodes in the pastoralist community is scaled at 0.74. This indicates that the severity of drought can cause a 74% catastrophic impact on pastoralists’ lives, property, natural environment and livelihoods. On the other hand, water scarcity, biodiversity decline, fodder scarcity, female-headed households, price instability, recurrent droughts, weather-dependent livelihoods, poor availability of early warning information and poor access to market factors have had positive and significant impacts on high vulnerability and the resulting consequences. Policy makers are therefore encouraged to develop strategies to help pastoralists build adaptive capacity and reduce vulnerability to climate hazards. These can be implemented by improving access to water and pasture, by providing early warning information, by providing rangeland management, by diversifying livelihoods and by limiting factors that increase pastoralists vulnerability and their impacts on their climate-dependent livelihoods.

Characterization and Identification of Major Constraints and Potentials of Kiltu Sorsa Watershed, in Guji Zone, Southern Ethiopia

Ethiopia is a country seriously affected by different natural resource degradation that included soil, vegetation, biodiversity and water degradation and climate deterioration. The study was conducted at Adola Rede District of Guji Zone, in Southern Ethiopia. The objectives of the study were to document baseline information on socioeconomic aspects and to document major biophysical and socio-economic constraints and potentials of the study watershed. The survey data were collected using key informant interview, focus group discussions, semi-structured interviews and guided field observations. A total of 60 respondents were selected for semi-structured interviews by means of simple random sampling methods. The majority (65%) of the respondent households were practiced physical and biological soil and water conservation activities. However, about 35% of the sampled households were not practiced soil and water conservation activities due to lack of awareness, lack of materials and labor. In the study watershed five major constraints such as land and soil related constraints, production related constraints, institutional and infrastructure related constraints, livestock related constraints and socio-economic related constraints were identified. However, suitable agro-ecology, availability of labor force, youth and women associations and informal institutions were the major identified potentials in the study watershed. Therefore, by using the potentials/opportunities of the study watershed and through providing quality extension services and training on soil and water conservation practices it is possible to enhance farmers participation and technical limitations. Moreover, for sustainable watershed management of the study area different soil and water conservation structures are very significant in various land use system of the study watershed through active participation of the local communities.

Determination of Optimum Irrigation Scheduling for Onion (Allium Cepa L.) at Bena Tsemay District, Southern Ethiopia

The effective use of irrigation methods is crucial for increasing crop productivity and promoting thesustainable use of agricultural land. Therefore, increasing agricultural water productivity is one of the most importantways to counteract future water scarcity. A field experiment was conducted to determine the optimal irrigation regimefor onion cultivation in Bena Tsemay district for two consecutive years. The experiment was laid out in a randomizedcomplete block design with five irrigation treatments and four replications. The treatments included five levels ofirrigation regimes: 60%, 80%, 100%, 120% and 140% available soil moisture depletion levels. The results showed thatirrigation regimes had a significant effect on plant height, bulb diameter, marketable yield and total yield, with a p-value of less than 0.05. The highest marketable yield (30.72 kg/ha) was observed at 100%ASMDL, followed by (30.49kg/ha) at 80%ASMDL. However, irrigation at 140%ASMDL resulted in the lowest yields of both marketable and totalonion. The two-year combined analysis revealed that the highest (6.5 kg/m3) water productivity was recoreded at 100%ASMDL, followed by (6.45 kg/m3) at 80% ASMDL. In contrast, the lowest water productivity (3.21 kg/m3) wasrecorded at 140% ASMDL. Therefore, based on the results of the current trial, it is recommended that the use of 80%ASMDL for a furrow irrigation system, and in similar agro ecology is a crucial option to increase the yield and waterproductivity of onion

Aerobic vaginitis, bacterial vaginosis, and vaginal candidiasis among women of reproductive age in Arba Minch, southern Ethiopia

Reproductive tract infections (RTIs) are a persistent public health threat worldwide, particularly among women in low-income countries of Africa, including Ethiopia, where drug resistance is also a growing problem. It is crucial to address this problem to ensure women's health and well-being. A cross-sectional study was carried out among a cohort of 398 women of reproductive age who sought medical attention at the Gynecology Department of the Arba Minch General Hospital, southern Ethiopia, from January to June 2020. They were chosen through systematic random sampling, and a pre-tested structured questionnaire was used to collect the data. The collection of vaginal and/or cervical swabs were done to diagnose bacterial vaginosis (BV) and aerobic vaginitis (AV) using Nugent and AV score analyses, respectively. The swabs were subjected to standard microbiological culture techniques to detect the isolates causing AV and vaginal candidiasis (VC). The susceptibility profiles of the causative agents of AV were checked by the Kirby-Bauer disc diffusion technique. Descriptive and inferential statistical analyses were also done. Aerobic vaginitis was the predominantly diagnosed RTI (n = 122, 30.7%), followed by BV (n = 117, 29.4%) and VC (n = 111, 27.9%). The prominent bacteria of AV were Escherichia coli (n = 36, 34.2%) and Klebsiella pneumoniae (n = 30, 28.5%). The overall rate of multidrug-resistant (MDR) bacteria was 65.71% (n = 69). History of abortion (p = 0.01; AOR = 4.0, 95% CI = 2.1, 7.7) and the habit of using vaginal pH-altering contraceptives (p = 0.01; AOR = 4.7, 95% CI = 2.5, 8.8) have the greatest odds of RTI. The high prevalence of RTIs in our study warrants an urgent intervention to minimize the associated morbidities and complications. The overall rate of MDR bacterial isolates necessitates the implementation of an effective surveillance program in the study setting.

Inoculation of Erythrina brucei with plant-beneficial microbial consortia enhanced its growth and improved soil nitrogen and phosphorous status when applied as green manure

Erythrina brucei has been applied as a green manure to improve soil fertility in southern Ethiopia. It has been nodulated by indigenous rhizobia. The objectives of this study were to evaluate the effects of E. brucei inoculation with microbial consortia consisted of Bradyrhizobium shewense, Acinetobacter soli and arbuscular mycorrhizal fungi (AMF)on E.brucei growth, soil nitrogen and phosphorous status after application as a green manure.A field experiment was conducted by inoculating E. Brucei with different microbial consortia. E. brucei inoculated with the microbial consortia were grown for 150 days. Its shoot length was measured at 60, 90, 120 and 150 days after planting. Then, plants were uprooted and mulched as a green manure. The soil nitrogen, available phosphorous and soil organic matter analysis were done. The experimental design was completely randomized block design with eight treatments comprised of three replications. Inoculated treatments did not show a significant (p < 0.05) difference in shoot length in the first 60 days. However, shoot length was increased between 19.1 and 41.3 %, 10.5–43.4 % and 8.7–37.6 %, respectively at 90, 120 and 150 days. The soil organic matter was improved in both inoculated and un-inoculated treatments. The improvements in the soil organic matter of un-inoculated treatments may be due to the decomposition of un-inoculated plants biomass in the soil. The B. shewense inoculation improved the soil nitrogen by 17 %. The soil phosphorous was improved in 57 % of inoculated treatments. The inoculation of E. brucei with microbial consortia enhanced its growth and improved soil fertility when applied as a green manure. Inoculating the green manure legumes with symbiotically effective rhizobia and plant-beneficial microbes can enhance the growth of E. brucei and its nutrient uptake.

Pre-extension Demonstration and Popularization of Silk Production Technologies in South Ethiopia

The study was conducted in Shebadino, Tula and Wondogenet districts of Sidama regional state of southern Ethiopia from 2018 to 2023 with the objectives of to evaluate the performance of silk production technologies at various levels of silk production with stakeholders/beneficiaries. The study also aimed to create awareness and develop confidence among silkworm producers, development agents, agricultural experts and policy makers for wider dissemination. Nine kebeles’ (the lowest administrative level), were selected from three (3) districts for the purposes of this study. Five (5) farmers from each kebele were selected, totaling 45 farmers, for technology pre-scale up and promotion. Three rounds of theoretical and practical training were given to these farmers after they were selected. Training in the third round focused on managing row silk and cocoons after harvest, with a first round that covered broad knowledge and the importance of sericulture. Of the farmers who were chosen and trained, 95.6 percent were women who began raising silk worms, producing cocoons, and processing row silk. Each farmer received 30 kilograms of castor seed and 50 disease-free adult moths for pre-scaling up and promotion of the technology. During the first year of the study period, 90%, 50%, and 40% of the disease-free moths that were disseminated laid eggs and developed into cocoons at Shebadino, Tula sub city and Wondogenet districts respectively. Sericulture is very beneficial to young people, particularly women, in terms of providing a variety of employment options and viable income without affecting their regular agricultural activities or the existing sociocultural equilibrium. Sericulture technology with its package used, knowledge and skill of the farmers (users) on the technology upgraded, continuous follow up assured by DAs and experts. This study highlights the significance of sericulture for rural development and offers insightful information for its dissemination.

The impact of household wealth on soil organic carbon and nitrogen stocks in enset (Ensete ventricosum (welw.) cheesman) based farming systems in southern Ethiopia

Enset [Ensete ventricosum (welw.) cheesman] is a multi-purpose perennial crop that is an important keystone species for home garden agroforestry systems in Ethiopia and has great potential to increase resilience to climate change, sequester carbon and reduce net greenhouse gas emissions. Therefore, it could be an important crop to be grown more widely in the future. Carbon sequestration is in part due to application of large amounts of organic matter to enset. However, availability of organic matter for use in enset-based farming systems is likely to be related to wealth status of farmers. Because evidence on the influence of wealth on soil carbon is limited, this study assessed influence of household wealth on soil organic carbon, nitrogen and carbon dioxide emissions from enset-based farming systems in southern Ethiopia. Farmlands managed by resource rich farmers had significantly higher organic carbon in 0–20 cm soil depth (4.6 % and 5.8 %) than those managed by resource-poor farmers (3.7 % and 4.3 %). Total nitrogen followed similar trends. Results suggest that wealth status influences soil properties by determining organic inputs, highlighting the importance of livestock. Resource-poor farmers who do not own livestock should therefore take measures to obtain inputs from other sources, such as compost or vermi-compost.

Chickpea (Cicer arietinum L.) growth, nodulation, and yield as affected by varieties, Mesorhizobium strains, and NPSB fertilizer in Southern Ethiopia.

A significant legume crop in Ethiopia, chickpeas (Cicer arietinum L.) have several advantages, including high nutritional value and the capacity to improve soils deficient in nitrogen through biological nitrogen fixation using several endosymbiotic Mesorhizobium spp. strains. However, the host variety, the soil's capacity to hold nutrients, and the endosymbiont's innate physiological traits all affect how efficient the strains are. The primary obstacles to its cultivation in the research area are inadequate agronomic methods and low soil fertility [low nitrogen (N), low soil organic matter (OM), low accessible phosphorous (P), sulfur (S), and boron (B)], which results in ineffective nodulation. To evaluate the effects of NPSB fertilization and inoculation, a field experiment was carried out in Buchach Kebele's Cheha area during the primary cropping season of 2021/22. The trial included two chickpea kinds (Local and Arerti), two NPSB levels (zero and 121 kg NPSB ha-1), and four levels of Mesorhizobium strains (CP-M41, CP-EAL 029, CP-M20b, and un-inoculated control). A randomized complete block design (RCBD) was used to organize the treatments in a factorial form with three replications. In comparison to the single application and the control, the interaction impact of strains, NPSB fertilizer, and variety greatly increased nodulation parameters, growth parameters, yield, and yield components. The Arerti variety combined with the CP-M41 Mesorhizobium strain and NPSB fertilizer had the maximum grain production (3177.16 kg ha-1). It yielded 15.96%, 24.06%, and 37.93% more than the Arerti with CP-M41 strain, Arerti with NPSB, and the control treatments, respectively. The partial budget analysis of the study treatments showed that the Arerti variety with the combined application of 121 kg NPSB ha-1 and Mesorhizobium strain CP-M41 inoculation produced the highest net return (102,092.6 ETB ha-1) with an acceptable marginal rate of return (618%). It has been found that the CP-M41 strain and the Arerti variety, when combined with 121 kg NPSB ha-1 application, is a suitable treatment combination to achieve increased chickpea crop yield and profit in the studied area. However, the results need further validation in the farmer's field before recommending to farmers.
