Effects of Methods and Rates of Phosphorus Fertilizer Application and Planting Methods on Yield and Related Traits of Maize (Zea mays L.) on Soil of Hawassa Area
An experiment was conducted to determine optimum rate and efficient method of phosphate fertilizer application and planting arrangement in maize at Hawassa. The treatment included one and two seeds per hill planting, spot and strip method of P fertilizer application and P levels of ĂÂ 0, 23, 46, 69 and 92 kg P2O5/ha. The results showed that higher mean values were obtained with one seed per hill planting which gave 5.1% grain yield advantage over two seeds per hill planting. Strip method of application had highly significant effect on grain yield and had 25 % yield advantage over spot method. However, P fertilizer rates had no significant effect and were negatively correlated with grain yield (r2 = -0.7). One seed plating per hill planting is recommended whereas applying P fertilizer beyond 20kg P2O5/ha is not advisable for production of maize at Hawassa and surrounding area
Age at sexual initiation and factors associated with it among youths in North East Ethiopia
Background: For behavioral as well as physiological reasons, early sexual debut increases young peoples' risk for infection with HIV and other STIs. Youths who begin sexual activity early are more likely to have high-risk sex or multiple sexual partners and are less likely to use condoms. It is crucial to understand the factors associated with early sexual initiation in a broader context for designing and implementing effective interventions targeting youth. Objective: The objective of the study was to determine the median age at first sexual intercourse and the associated factors of sexual initiation among rural and urban youths (age 15- 24 years). Methods: A comparative cross sectional study was conducted between, March 1 -15, 2008, in Dessie town and Dessie Zuria Woreda. To draw a total sample of size 1294 (647 urban and 647 rural), a multistage cluster sampling was used. Bivariate and multivariate analyses were employed. Moreover, Kaplan Meier survival analysis was used to estimate the probability of sexual initiation at various age stratified by residence and sex. Result: About half, 51.3% of the youths have ever had sex. Rural youths initiate sexual intercourse at lower age than their urban counterparts with mean (±SD) (16.49+2.11) for rural and (17.18+2.32) for urban youths. The median age at sexual debut was 16 years for rural and 17 years for urban. The hazard ratio for sexual imitation was significant (AHR [95% CI] =1.45 [1.19, 2.55]. Multivariate analysis showed that being female by gender (AOR [95% CI]=1.56 [1.11, 2.19]), chewing Khat (AOR [95% CI] = 2.05 [1.05, 3.96]), drinking alcohol (AOR [95% CI] = 2.16 [1.12, 4.18]), watching pornographic materials at age < 18 years (AOR [95% CI] = 24.13 [3.28, 177.80]) and being less connected with parents (AOR [95% CI] =2.30 [1.35, 3.91]) were associated with early sexual initiation. Conclusion and Recommendation: Early sexual initiation prevails more in rural than urban youths. Delaying sexual debut can be achieved through well designed sexual education programs at earlier life. Strengthening the norm of virginity should be advocated. Equally, ways to access condoms and other contraceptives especially to rural youths should be sought for those who already initiate sexual intercourse.
Prevalence of major sheep diseases and analysis of mortality in selected model sheep villages of south Gondar administrative zone, Ethiopia
A cross sectional and retrospective case study design were carried out from May 2008 to April 2012 in model sheep villages of Farta and Lay Gaint districts with the objective of identifying major sheep diseases, to assess the magnitude of sheep mortality and recommend disease and mortality control options in the study areas. Retrospective study was employed for 184 (89 from Farta and 95 from Lay Gaint) diagnosed sheep from case registration book of respective woreda and kebele veterinary clinics to collect information about the prevailing sheep diseases in the study areas. Among major sheep diseases, Respiratory Disease Complex (RDC) (38.6%), Enteritis (22.6%), Fasciolosis (19.6%), Generalized septicemic condition (GSC) (13.0%), Sheep pox (12.0%), Foot rot (2.2%) and Orf (1.1%) were commonly diagnosed ovine diseases in the study areas. Ninety four (94) questionnaires were administered to sheep producers to understand sheep management practices, identifying major sheep production constraints and to assess the magnitude of sheep mortality. A total of 242 fecal samples were collected for the analysis sheep internal parasites. The major identified internal parasites of sheep were Strongyle spp (43.0%), Paramphistmum (21.5%), Fasciola (20.2%), Tricuris (8.3%), Monezia (8.3%), Coccidia (5.0%) and Schistosoma (1.7%). A significant differences (P<0.05) was observed in Fasciolosis across study districts which showed higher prevalence of Fasciola (14.5%) from Farta and relatively lower (5.8%) from Lay Gaint district. EPG count shown that, 83.6% of sheep positive with nematode was categorized in the range of light infection (50-800 EPG) which depicts the level of nematode infection in the population was lower. Comparison of sheep mortality over years and breed shown that, higher (26.4%) and lower (6.3%) mortality was recorded from all sheep breeds (Washera, Farta and Cross) in the year 2009 and 2012 respectively. In conclusion, the present high mortality rate and prevalence of sheep diseases were high to cause momentous economic losses in the study area. Therefore, strengthening the control effort was suggested.Key words; Farta sheep, Model sheep villages, Ovine disease, Washera sheep, Mortalit
Yield Gaps of Major Cereal and Grain Legume Crops in Ethiopia: A Review
In Ethiopia, smallholder farmers are responsible for most food production. Though yield levels in grain crops have improved greatly over the years, they are still much lower than their potential. The source of yield improvements and the causes of those yield gaps are not well understood. To explain the drivers of yield gaps and current sources of yield improvements in four major cereals (teff, maize, wheat, and sorghum) and three grain legumes (faba bean, common bean, and soybean), we accessed the databases of the Global Yield Gap Atlas, the Food and Agriculture Organization of the United Nations, and the Central Statistical Agency of Ethiopia. Refereed journal articles and grey literature were sought in online databases using keywords. The results showed large increases in production of grain crops with little or no increase in areas of production. The yield increases were primarily attributed to genetic gain rather than agronomic improvements. Farmersâ yields remain far lower than those from on-farm trials and on-station trials and the calculated water-limited yield potential. Currently, yields of wheat, maize, sorghum, and common bean in Ethiopia are about 26.8, 19.7, 29.3, and 35.5% of their water-limited yield potentials. Significant portions of the yield gaps stem from low adoption and use of improved varieties, low application of inputs, continual usage of un-optimized crop management practices, and uncontrolled biotic and abiotic stresses. Proper application of fertilizers and use of improved varieties increase yield by 2 to 3 fold and 24â160%, respectively. Cereal-legume intercropping and crop rotation practices increase yield while reducing severity of pests and the need for application of synthetic fertilizers. In contrast, abiotic stresses cause yield reductions of 20â100%. Hence, dissection of the water-limited yield gap in terms of technology, resource, and efficiency yield gaps will allow the prioritization of the most effective intervention areas
Enabling equitable collective action and policy change for poverty reduction and improved natural resource management in the Eastern African highlands:
"The role of local and external institutions in natural resource management (NRM) is gaining attention in the literature, fostering greater understanding of the relationship between collective action and poverty, collective action and equity, and the conditions under which collective action institutions take root. It has also led to increased understanding of how uncritical practices by external development institutions can propagate social inequities in NRM. Yet little research has been conducted to understand how to foster local collective action institutions where they are absent, or to improve institutional practice. This research integrates empirical and action research in an effort to generate âworking solutions' to problems facing rural communities in their efforts to manage their natural resources in the highlands of Ethiopia and Uganda. Following a brief introduction to the literature and the research, findings are presented according to two distinct phases of research. Data are first presented on existing forms of collective action, the influence of local and external institutions on economic development, and NRM problems that persist despite their negative livelihood consequences. Action research themes selected from a list of identified problems are then presented in greater detail, with lessons learnt thus far in attempting to overcome institutional barriers to improved NRM. The paper concludes with a discussion of the implications of findings for research, institutional practice, and policy." authors' abstractNatural resource management, Collective action, Equity, Livelihoods, East African highlands, Gender, Environmental management,

Anxiety and depression among cancer patients in Ethiopia: a systematic review and meta-analysis
IntroductionAnxiety and depression are among the common comorbidities of people diagnosed with cancer. However, despite the progress in therapeutic options and outcomes, mental health care and support have lagged behind for cancer patients. Estimating the extent and determinants of mental health disorders among cancer patients is crucial to alert concerned bodies for action. In view of this, we aimed to determine the pooled prevalence and determinants of anxiety and depression among cancer patients in Ethiopia.MethodsRelevant literatures were searched on PubMed, African Journals Online, Hinari, Epistemonikos, Scopus, EMBASE, CINAHL, Cochrane Library, and Gray literature sources. Data were extracted into an Excel spreadsheet and analyzed using STATA 17 statistical software. The random effect model was used to summarize the pooled effect sizes with their respective 95% confidence intervals. The I2 statistics and Eggerâs regression test in conjunction with the funnel plot were utilized to evaluate heterogeneity and publication bias among included studies respectively.ResultsA total of 17 studies with 5,592 participants were considered in this review. The pooled prevalence of anxiety and depression among cancer patients in Ethiopia were 45.10% (95% CI: 36.74, 53.45) and 42.96% (95% CI: 34.98, 50.93), respectively. Primary and above education (OR= 0.76, 95% CI: 0.60, 0.97), poor social support (OR= 2.27, 95% CI: 1.29, 3.98), occupational status (OR= 0.59; 95% CI: 0.43, 0.82), advanced cancer stage (OR= 2.19, 95% CI: 1.38, 3.47), comorbid illness (OR= 1.67; 95% CI: 1.09, 2.58) and poor sleep quality (OR= 11.34, 95% CI: 6.47, 19.89) were significantly associated with depression. Whereas, advanced cancer stage (OR= 1.59, 95% CI: 1.15, 2.20) and poor sleep quality (OR= 12.56, 95% CI: 6.4 1, 24.62) were the factors associated with anxiety.ConclusionThis meta-analysis indicated that a substantial proportion of cancer patients suffer from anxiety and depression in Ethiopia. Educational status, occupational status, social support, cancer stage, comorbid illness and sleep quality were significantly associated with depression. Whereas, anxiety was predicted by cancer stage and sleep quality. Thus, the provision of comprehensive mental health support as a constituent of chronic cancer care is crucial to mitigate the impact and occurrence of anxiety and depression among cancer patients. Besides, families and the community should strengthen social support for cancer patients.Systematic Review Registrationhttps://www.crd.york.ac.uk/prospero/, identifier CRD42023468621
