The experiment was conducted in laboratory and field together at Department of Genetics and Plant Breeding, SHIATS, Allahabad, U.P. during kharif (2014), in order to standardize the best method of priming specific to cluster bean. Four methods of priming viz., osmopriming, hydropriming, halopriming, and solid matrix priming were evaluated by screening a range of durations and concentrations viz., T0-Unprimed Control, T1 Distilled water hydration (for 18 hrs), T2 Polyethylene glycol 6000 (25%) hydration (for 20 hrs), T3-KNO3 (3%) hydration (for 22 hrs), T4-NaCl (3%) hydration (for 22 hrs), T5-Isabgoal gel hydration (for 24 hrs). It was found that all the priming methods showed significant differences with the control and the highest germination %, seedling length, weight and vigour index were observed in T2 for PEG 6000 priming for 20 hrs. The study helps to improve the quality of seeds with the help of seed priming treatments which are cost effective and economic, non toxic and eco friendly
