Effect of Halo, Osmo and Hydro-Priming on Yield and Yield Related Traits of Common Bean at Raya Valley of Tigray Region, Ethiopia
Résumé
This study was carried out in order to evaluate effect of seed priming on seed yield and yield components of common bean (Phaseolus vulgaris L.) at Tigray region, Mehone agricultural research center. Low quality seed causes poor seedling emergence, which is one of the biggest barriers to closing the enormous yield gap, particularly in environments that are prone to drought. In order to assess the impact on germination and yield of the Nasr variety of common bean, hydro, osmo, and halo priming methods were applied, along with priming durations of 6, 12, and 18 hours using RCBD design. ANOVA analysis showed that between all experimental traits there was significant difference. Minimum emergency date (6.94) was recorded by priming with potassium nitrate and priming duration of 18hr (7.11). The shortest (77.77) and longest date (82.44) flowering date was registered by priming with manitol and water respectively. Maximum value of Pod per plant, seed per plant and seed yield was obtained from hydro priming and 6hr priming duration. In general this study reveal that seed priming enhance seed germination quality and improve the yield and yield related traits so that accelerate over all yield and yield related of the common bean.
