Field Performance Evaluation of Climbing Beans (Phaseolus vulgaris L.) Varieties for Agronomic Traits Under Pawe District, North-West, Ethiopia

Background and Objective: Adaptation and promotion of improved crop varieties was one of the best means to solve the shortage of widely adapted crop technologies. Therefore, the objective, of the study was to evaluate the adaptability and field performance of climbing bean varieties’ yield and yield-related traits with a full practice. Materials and Methods: Twenty-five climbing bean varieties with standard check, Dandesu, were involved in the study during the 2020 and 2021 cropping seasons with full packages of agronomic practices. Triple lattice design with three sets of replications applied. The agronomic traits evaluated were 50% days to flowering, 95% days to pod maturity, plant height, angular leaf spot, number of pods per plant, number of seeds per pod, hundred seed weight, adjusted grain yield per hectare and other yield-related agronomic characters. Results: There was a significant difference between treatments at (p<0.05 level). The highest grain yield was obtained from RWV1272 (1904.30 kg/ha) followed by CAB2 (1765.60 kg/ha) and SELIAN06 (1692.50) while the lowest grain yield was scored by CMKN1810 (805.10 kg/ha). The RWV1272 (17.29) scored the highest pods per plant whereas CMKN1551 scored the lowest (7.48); this implied the variety RWV1272 was a high grain yielder among the tested climbing beans for this study. Besides; the yield advantage of better-performing climbing bean varieties (RWV1272, CAB2 and SELIAN06) over the standard check (Dandesu) was 58.06, 46.55 and 40.48%, respectively. Conclusion: Based on the data collected, at field conditions, variation occurred among climbing bean varieties; therefore, the performance evaluation of climbing bean varieties was an indicator for future improvement of dry beans and recommended for further evaluation, demonstration and large-scale demonstration (LSD) purposes for the study area (Pawe District) and similar areas.
