Abstract: Furrow length and water flow rate had a significant effect on crop yield, crop water use efficiency and irrigation performance indicators. Therefore, objective the study was to determine optimum combination of furrow length and flow rate to enhance irrigation efficiency. Field experiment was carried out at Kersa woreda, Jimma Zone, South Western part of Ethiopia, during cropping season of 2019, 2020 and 2021 for three consecutive years using Belete potato variety as a test crop. The treatment comprised three furrow length (50, 30 10 m) and three flow rates (0.45, 0.67, and 0.89l/s) laid out in split plot design with three replications where furrow length used as the main plot and flow rate as sub-plot. Results of over year analysis showed that tuber yield, biomass yield and tuber diameter significantly affected by different furrow length and flow rates. The highest and lowest tuber yield was obtained from L2Q1 (39.49 t/ha) and L3Q2 (29.09t/ha) respectively. The highest Biomass yield of 35.75 ton/ha was obtained from L2Q1 treatments whereas the lowest (20.34t/ha) recorded from L1Q3 treatment. Interaction of furrow length and flow rate does not affect water productivity, water application efficiency and deep percolation ratio. Similarly furrow length was not significant (p>0.05) on water productivity of potato. However flow rate influences water productivity significantly (p<0.05). The water productivity for both furrow length and flow rate ranges from 0.41 to 0.45 Kg/m3. Both furrow length and flow rate had significant (p<0.05) impact on irrigation water application efficiency. The maximum water application efficiency was obtained from 30m furrow length (29%) and 0.67l/s flow rate (27%). Based on the current finding potato belete variety resulted in maximum yield at combination of 30m furrow length and 0.89l/s flow rate (L2Q1) using furrow irrigation.

Abstract: Faba bean (Vicia faba L.) is one of the major leguminous crops grown in the world. However, the national average faba bean yield is very low compared to its potential yield in Ethiopia, particularly in north eastern Ethiopia due to lack of organic fertilizer and insufficient number of indigenous Rhizobium. To achieve this objective, this green house experiment was arranged in CRD with three replications in the factorial combination of three levels of rhizobium strains (non-inoculated, RS-17 and RS-1035) and four rates of vermicompost (0, 5, 10 and 15 ton/ha) treatments. It was carried out from October 2020 to May 2021 using Dosha faba bean. All growth and yield parameters data were given to the analysis of variance (ANOVA) using statistical analysis software version 9.4. The result showed that the main effect of rhizobium strains enhanced growth parameters (nodule number, symbiotic effectiveness, and number of leaves per plant) while improving total biomass yield. Whereas, the main effect of vermicompost rate were predominantly on yield parameters (number of productive piller, number of pod per plant, number of seed per pod, straw yield, total biomass yield) while improving plant height and number of leaves per plant. On the other hand, the interaction effect of rhizobium strains and vermicompost rate affected plant height, number of leaves per plant, number of seed per pod, straw yield, and total biomass yield. Treatments that received combined RS-17 and 15 ton/ha vermicompost provided the maximum plant height (79.3 cm), number of leaves (70.5), number of seeds (3.75), straw yield (191.6kg/ha) and biomass yield (5.686 ton/ha). This implies that combined application of vermicompost and using inoculated seed can improve productivity faba bean at smallholder farmers’ level. Therefore, it is recommended to use integrated application of 15 ton/ha vermicompost and RS-17 inoculants to increase productivity of faba bean in the study area. Furthermore, the experiment should be supported by field studies on different area soils.

Abstract: Tomato is among the major horticultural crops cultivated under irrigated areas of Ethiopia now days. Considering this pre-extension demonstration and evaluation of adapted tomato technologies under irrigation was conducted through selecting few districts of Kelem and West Wolega Zones with the objective of demonstrating and evaluating the best performed tomato technologies. Two varieties of tomato (Melka Shola and Melka Salsa) were used for the demonstration and evaluation on farmers' field under their management condition. Essential data were collected from demonstration plots and were analyzed using simple descriptive statistical tools. The result indicates that Melka Salsa provided average yield of 389.5qt/ha while Melka Shola and local varieties provided 339.25qt/ha and 301.75qt/ha, respectively. The yield advantage of 29.08% and 12.43% were obtained from Melka Salsa and Melka Shola over the local variety, respectively. Participatory variety evaluation and selection techniques were used. During PVES farmers’ preferences feedbacks were collected and analyzed using pair wise and matrix rankings. FRG members and the trial farmers were invited in the demonstration field to evaluate the performance of the verities setting their own criteria. In the ranking, Melka Salsa variety was selected as the best performed variety than both the local and Melka Shola varieties. Accordingly, Melka Salsa variety was preferred and selected firstly by farmers for its high yielder, medium fruit size, fruit shape, plant canopy cover, early maturity, number of fruit per plant, number of fruit per pod and marketing quality. On the other hand, Melka Shola was selected secondly for its disease tolerance, large fruit size and medium yielder. Thus, Melka Salsa and Melka Shola varieties were recommended for scaling up in West and Kelem Wolega zones and similar agro-ecologies. Therefore, the offices of agriculture, cooperatives, unions and NGOs should multiply and provide the selected and recommended tomato varieties for those thirsty farmers in the study areas.

Abstract: Late blight of potato is the most economical disease which can result into crop failures if it is not properly managed early. So that, our objective was to update yield loss assessment on late blight disease of potato. The experiment was arranged in a randomized complete block design (RCBD) with three replications with a total of 5 treatments. All fungicides significantly controlled the disease at both early and late stage of the crop in comparison to the unsprayed plot. The minimum 151.7 AUDPC was recorded on the tretement was sprayed by fungicide supper plus. The lowest next three treatements were spayed by Mancozeb, Zorphic, and Redomil, were resulted 320.8, 350, 408 AUDPC respectively. The control treatment (water sprayed) had the highest AUDPC (1131.7). The highest mean tuber yield (34.4t/ha) was obtained from fungicide Zorphic followed by the standard fungicide (Redomil) which gave (30 t ha-1) whereas the control treatment gave 5.7 t ha -1. The highest yield loss (72.9%) occurred in the unsprayed plots of cultivar Jalenie compared with Zorphic fungicide sprayed plots. Generally all disease and yield parameter indicate that among the four fungicides spray; Zorphic was the most effective followed by Redomil Gold, Supper plus and Mancozeb sprayed plots. Thus based on the performance of fungicides for the management of late blight, potato yield and yield components, Supper plus and zorphic deserve to be considered as an alternate fungicide to the widely used fungicide Mancozeb and Redomil, respectivelly in the country.
