Background: Ginger bacterial wilt is the most destructive disease that causes qualitative and quantitative rhizome yield losses in Ethiopia. Field studies were conducted to assess yield loss caused by bacterial wilt of ginger in different wilt management systems at Teppi and Jimma, Ethiopia, during 2017. Management systems were host resistance (Boziab and Local) and cultural practices (lemon grass, potassium fertilizer and soil solarization), which were applied as sole and in different levels of integrations. The experiments were factorial arranged in a randomized complete block design with three replications. Disease, growth, yield and yield-related data were collected from central rows of each experimental plot. Data were subjected to analysis of variance using linear general model (GLM) procedure of SAS version 9.3. Mean separation was made using least significant difference test. Correlation among parameters and linear regression of rhizome yield versus final wilt incidence were computed using Minitab 14 statistical package. Results: Analysis of variance indicated that variety, cultural practices and variety × cultural practice interaction effects significantly reduced wilt incidence and increased rhizome yield and its components. Variety Boziab recorded relatively more yield and yield components than the Local variety. Rhizome yield gains of about 51.4% in Local and 51.9% in Boziab at Teppi and 39.4% in Local and 49.1% in Boziab at Jimma were obtained due to integrated application of lemon grass with soil solarization and soil fertilization. The mean relative yield loss calculated for control plots due to bacterial wilt ranged from 51.4 to 51.9% at Teppi and 39.4 to 49.1% at Jimma. The lowest relative yield loss was computed from plots treated with either lemon grass with soil fertilization and solarization or lemon grass with soil fertilization. Final wilt incidence was inversely and highly significantly (P ≤ 0.001) correlated (r = − 0.90** and − 0.88**) with rhizome yield of Boziab and Local, respectively, at Teppi. The slope of the regression line also estimated that for each unit increase in percent of final mean wilt incidence, there was a rhizome yield reduction of 0.18 t ha −1 for Boziab and 0.19 t ha −1 for Local variety at Teppi. Similar trends were observed at Jimma. Moreover, the most integrated treatment provided higher net benefit with optimum marginal rate of return than others. Conclusion: The overall results indicated that integration of host resistance with cultural practices reduces yield loss, improves ginger productivity and significantly reduces bacterial wilt epidemics, and thus, it is recommended in the study areas and other related agroecologies.

Coffee Arabica is an essential commodity to the livelihood of millions of Ethiopians and its quality had critical importance to the coffee industry. A study was conducted to evaluate coffee quality attributes of nine newly released coffee cultivars subjected to open sun (direct sun light) and lath house-drying methods. The experiment was designed in complete randomized design factorial with two factors (cultivars and drying methods). Coffee cultivars were (Gawe, Dessu, 744, 7440, 74148, Gesha, Merdacheriko, Wushwush and Catimor J-19) prepared using wet (washed) processing method during harvesting of 2017/18 cropping season, which were collected from different altitude of south west, Ethiopia. Cup quality was evaluated by a team of certified panelists at Jimma agricultural research center coffee processing and quality analysis laboratory. The highest value in most cup quality attributes were record in cultivars of Gesha and 74148. Similarly, cultivars of 744 and 7440 were highest in all cup quality parameters. Net lath house drying method was better in all cup quality attributes. Effect of drying method was significant difference (P<0.05) on cup quality parameters such as aromatic quality, astringency, bitterness, body and flavor. The interaction effect of cultivar and drying method shown significant difference (P<0.05) on cup quality parameter except aromatic intensity. In the future to improve and maintain coffee quality different drying method should be practiced.

The aims of this study were to determine appropriate time and efficient techniques of harvesting methods for Panicum Coloratum forage. The experiment was designed in randomized complete block design (RCBD,) in 4x4 factorial combinations of harvesting methods (mowing, sweating, shaking and sweeping) and time harvesting (14 th , 21 th , 28 th and 35 th days) after full anthesis. The experiment was replicated four times. The Results revealed that the mean number of inflorescences per M s , number of racemes per inflorescence, number of spikelet per raceme f were significantly different across the years. Seed yield and seed germination percentage were affected by different harvesting methods and time of harvesting and also influenced by their interactions. The sweating method gave more seed yield 633 and 618kg/ha on the 28 th and 35 th days of harvesting with 66 and 64 germination percentages respectively. In conclusion, smallholder farmers or commercial seed producers can produce optimum seed yield and quality by sweating method at 28 or 35 days of harvesting after full anthesis.
