Evaluation of Haricot Bean [Phaseolus vulgaris (L.)] Varieties for yield and yield Components at Ebinat and Tach Gayint Districts of South Gondar Zone, Northwestern Ethiopia

Background: Haricot bean is the most important food legumes in Ethiopia. However, low productivity is the major problem in South Gondar zone, which is mainly associated with lack of recently released high yielder varieties in the areas. The aim of this study was an attempt to identify suitable high yielder haricot bean varieties for the study areas and similar agro ecologies. Methods: This study was conducted during the rainfed season of 2021 and 2022 at Ebinat and Tach Gayint districts in South Gondar zone, Ethiopia. Four haricot bean varieties with one local check were used as a treatment and laid out in randomized complete block design with three replications. Result: Analysis of variance showed a highly significant variability among the varieties for days to maturity, pod length, pods per plant, seeds per pod, grain yield and 100 grain weight. All these traits showed a highly significant difference by location variations. Variety by location interaction also showed a significant variation on days to maturity, pods per plant,100 grain weight and grain yield. SER119 was found the highest yielder variety with mean yield of 2861.00, 2887.50 and 2231.59kg ha-1 at Burkoch, Fenta and Balarb locations, respectively. This variety has a respective yield advantage of 59.41%, 47.01% and 38.70% over the local check. Whereas, Awash mitin showed a highest yield at Daka (2285.70 kg/ha) and Anseta (1995.50 kg ha-1) locations with respective yield advantage of 33.96% and 39.95% as compared to the check cultivar. Therefore, SER119 and Awash mitin varieties could be recommended for Ebinat and Tach Gayint districts and similar agro-ecologies to each location.
