Abstract:

To standardize the best concentration and duration of osmopriming of aged seed of chickpea variety, NBeG-3 with Polyethylene Glycol, an experiment was conducted in Factorial Completely Randomized Design with four replications. The seed was subjected to osmopriming with different concentrations of PEG 6000 viz., 0, -0.5, -1.0, -1.5 and -2.0 MPa for various durations viz., 3, 6, 9, 12 and 24 hours. The seed quality was assessed by testing for germination in between paper method and sand method. In both the methods of testing, concentration of PEG, duration of osmopriming and their interaction exhibited highly significant effect on germination, seedling length and seedling vigor index. Among all the concentrations used, seed primed with -0.5 MPa PEG recorded highest germination, root length, shoot length, seedling length, root / shoot ratio and seedling vigor index. Among the various durations, osmopriming for 6 hours showed highest improvement in seed quality. The interaction effect of seed priming with -0.5 MPa PEG for 6 hours also showed highest improvement in seed quality attributes.
