Laboratory and lath-house experiment were carried out at National Seed Quality Control Laboratory Center, and at Debre Zeit Agricultural Research Center lath-house, Ethiopia, respectively with the objectives to determine the effectiveness of seed priming and variety on seed quality and stand establishment. Experimental factors were three priming media [H2O, 0.5% KH2PO4, unprimed)] and six Chickpea varieties (DZ-10-4, Arerti, Habru, DZ-10-11, Akaki and Natoli) arranged in CRD with four replications. The laboratory results revealed significant differences (p<0.01) for all parameters except vigor index II, which was significant at (p<0.05) among different priming treatments and variety in seed germination, all seed vigor tests. The interactions of the main effect were significant (p<0.01) for all quality parameters excluding vigor index II, seedling shoot and root length and seedling dry weight. Significant correlations were also observed between emergence index and most of the vigor parameters. Moreover, water priming enhanced the germination and vigor index I of all varieties except DZ-10-4 and Habru; speed of germination of Arerti and electrical conductivity of all varieties tested. Hydropriming decreased electrical conductivity of seeds by 20% as compared to osmopriming. Therefore, it can be concluded that hydro priming can step-up economical benefit of chickpea growing farmers.
