Abstract
Selection of appropriate varieties and quality seed to be planted is the most important steps in boosting agricultural production; failures to do so would result in loss of yield or market acceptability of crops. To ensure this demonstration of improved potato varieties were conducted in West and Kellam Wollega Zones of Oromia national regional state. Different participatory technology evaluations were employed to enable farmers to select the variety/varieties which fit their local conditions based on their own preference. The result obtained indicated that, the production of Belete variety can increase potato production by 56.26% and Gudane can increase potato production by 49.95% in Zones compared to the local practice. More importantly, farmers were enabled to select varieties based on their own criterion, Accordingly, the direct matrix ranking indicated Belete variety as their first choice with the total percentage of 42.32%, Gudane and Local second and third with total percentage of 38.62% and 19.05% respectively. Besides, the profitability analysis indicated higher profit was obtained from Belete variety followed by Gudane. Therefore, based on the agronomic yield under farmers’ management conditions and farmers’ preference to the varieties, extension service providers and other concerned bodies should give attention to increasing the adoption of improved Belete and Gudane varieties in the target areas to boost potato production.

Highlights
Result and discussion 3.1 Yield performance of demonstrated potato varieties The result obtained indicated that yield performance of Belete superiority over others varieties
Belete variety was selected first for its tolerance to disease, higher yield over other six varieties demonstrated in Amhara region (Asresie et al 2015) and Gudane was selected as the good cooking quality by the study conducted by Hailu et al, 2020
We conducted the demonstration of the two top performed varieties for validation under farmers’ management condition
Summary
2.3 Materials used Three varieties of potatoes namely Belete, Gudane and Local were used for this demonstration trial with recommended fertilizer rate of NPS 195 kg ha-1 and Urea 165 kg ha-1. 3. Result and discussion 3.1 Yield performance of demonstrated potato varieties The result obtained indicated that yield performance of Belete superiority over others varieties. Result and discussion 3.1 Yield performance of demonstrated potato varieties The result obtained indicated that yield performance of Belete superiority over others varieties This improved variety with improved management practices gave a tuber yield of 34.69-ton ha-1 followed by Gudane with magnitude of 33.29-ton ha-1(figure 1). The biggest tuber size (cm plant-1) was obtained from Belete variety, it was higher by 12.5% and 39.70% over Gudane and Local respectively (figure 3), coinciding with Jafar et al, 2020. The highest number of marketable tubers was obtained from Gudane variety with mean value of 13.92 followed by Belete and Local with magnitude of 11.91 and 10.35 respectively (figure 4). This difference could be attribute to the agro ecological and soil fertility difference between the locations
