The most constraints of tef productions are lodging, drought, low yield cultivars; insect and disease affected the growth of tef. These, factors causes inconsistence performance yield due to GEI. The objective was to evaluate tef genotypes on their yield performance, stability and parametric stability to select most independent and informative statistics method. The experiment was conducted at four locations for two seasons; with design of RCBD three replications, two standard checks and 19 tef genotypes. Data was collected on grain yield and analyzed by R software and STABILITYSOFT. The analysis of variance for the combined mean of grain yield showed that there was significance difference (P<0.001) between genotypes, environments and GEI. Yield performance was influenced by Environments and GEI. The mean grain yield of genotypes over GEI varies from 820.94kg/ha to 2438.90kg/ha, while the genotype grain yield was ranged from 1382 to 1989kg/ha. G19, G17 and G6 were identified the higher grain yield performance over seven environments. Whereas, G8 and G11 were the lowest yielding tef genotypes. Nine parametric methods and GGE biplot were used to evaluate the stability of the genotypes. G19 was the most stable following G17 and would be grown for unfavorable growing environments. However, G6 was stable for favorable environmental condition. G19 and G17 had static stability and fitting for area faced with erratic rain fall. Even though, parametric stability did not show a positive and statistically significant correlation with mean yield the Mean variance component (θi) is selected with GGE biplot for evaluation of tef genotypes in the development of cultivar. Effective selection of variety would be best if mega-environment, representative and discriminating testing areas are identified.

Background: Disposal of pharmaceutical waste among patients is a global challenge especially in developing countries like Ethiopia. Improper medication disposal can lead to health problems and environmental contaminations. Therefore, the present study aimed to assess disposal practices of unused medications among patients in public health centers of Dessie town, Northeast Ethiopia. Methods: A descriptive cross-sectional study was conducted among 263 patients in four public health centers of Dessie town, Ethiopia from March to June, 2019. Face-to-face interviews using structured questionnaires were used to collect data from each study subject. Results: The majority of the respondents, 224 (85.17%) had unused medications at their home during the study period. The most commonly reported disposal method in the present study was flushing down into a toilet 66 (25.09%). None of the respondents practiced returning unused medications to Pharmacy. Moreover, 85 (32.31%) of the respondents reported never disposing their medications and believed that it is acceptable to store medications at home for future use. Conclusion: In the present study, there was a high practice of keeping medications at home and most of the disposal practices were not recommended methods. In addition, most of the respondents did not get advice from pharmacists and other health care professionals on how to dispose off unused medications. Hence, there is a need for proper education and guidance of patients regarding disposal practices of unused medications.

Abstract This study evaluated the interaction between the stage of maturity of Eragrostis tef (teff) grass and supplemental energy source on ruminal fermentation characteristics and nitrogen (N) utilization. Six ruminally-fistulated beef heifers were used in a 3 × 3 split-plot design (21 d periods). The whole plot factor was stage of maturity of teff hay [early- (EH) or late-heading (LH)], and the subplot factor was supplemental energy source [no supplement (CON), rolled corn grain or beet pulp pellet (BP)] fed at 0.5% of body weight. Feed intake was measured daily. Indwelling pH loggers were used to measure ruminal pH (d 14 to 21) and ruminal fluid was collected from d 19 to 21 to determine fermentation characteristics, as were feces and urine to measure N excretion. Data was analyzed using PROC MIXED in SAS. There was no stage of maturity × supplement interaction for all measurements (P ≥ 0.17). Although dry matter intake (DMI) tended to be greater (P = 0.07) for heifers fed EH than LH hay, it did not differ (P = 0.88) across supplements. Ruminal acetate concentration tended (P = 0.098) to be greater for EH than LH heifers, whereas butyrate, isobutyrate, and isovalerate concentrations were greater (P ≤ 0.045) for BPP than CON heifers. However, the duration and area pH &lt; 6.2 and 5.8 did not differ (P &gt; 0.12) across treatments. Except for microbial N flow, which was greater (P &lt; 0.01) for EH than LH heifers, there was no stage of maturity or supplement effect (P ≥ 0.14) on measures of N utilization. In summary, feeding teff hay harvested at the EH than LH stage of maturity increased DMI and microbial N supply, whereas feeding corn and BP as energy supplements to beef heifers had no effect on ruminal pH.
