Common bean in sub-Saharan Africa is an important crop for food security and nutrition. It plays a big dietary role to both rural and urban households. It is a major food and cash crop in Ethiopia and has substantial national economic. It is often grown as cash crop by smallholder farmers and used as a major food legume in parts of the country where it is consumed in different types of traditional dishes. The value of haricot bean in terms of economic return and food security increases with the
... use of recently adapted varieties that have better yield and resistance to disease and moisture stress whereas the improved varieties are lacking in the study areas. Therefore, participatory demonstration of improved haricot bean technologies was conducted in two potential midland districts of Guji zone in 2020. The main objective of the study was to popularize improved haricot bean variety at midlands of Guji zone. Adola Rede and Wadera districts were selected based on their potential to grow haricot bean and two peasant associations from each district were selected in criteria of their accessibility. Participatory approach was followed to implement the activity. 15 farmers of gender inclusive were established as FRG at each peasant association. From one FRG, three experimental farmers were nominated based on their consent to provide sufficient and suitable land for experiment. An improved haricot bean of Ibbado variety with one commercial variety was planted on selected farmers' land with a single plot size of 10 m x 10 m. Recommended seed rate of 100 kg ha -1 with a spacing of 40 cm and five cm between rows and plants were used respectively and an inorganic fertilizer (NPS) rate of 100 kg ha -1 at planting time. Farmers, DAs, SMSs, and different stakeholders were participated on organized training, field visit &joint monitoring and evaluation and field day on which two-way communication encouraged and experience was shared. Quantitative data such as yield and knowledge change of the farmers were analyzed using independent t test and paired sample t test respectively whereas farmers' feedbacks were analyzed qualitatively. Costs and income gained were analyzed using excel. The result of this study showed that mean difference in knowledge score before and after experiment was significantly higher. An average yield of, 23 quintals ha -1 and 12.4 quintals ha -1 for improved haricot bean and commercial respectively. The improved variety also revealed a yield advantage of 85.48% and incremental benefit cost ratio of 19.27 over the commercial. Therefore, recommended for up scaling. However, there is a need for seed of Ibbado variety. So, BoARC should focus on multiplying improved haricot bean of Ibbado variety. Any seed multiplier organizations like unions and cooperatives should give due emphasis for Ibbado seed.
