Ageing is a universal physiological process that occurs in all living organisms and its impact on modern agricultural practice has become a major concern. Seed viability and seed storability are well predicted by accelerated ageing. The current research looks at how the different plant products influence the storability of greengram seeds through an artificially accelerated ageing test. Seed quality parameters viz., rate of germination, germination percent, root length, shoot length, dry matter production and vigor index were assessed in the laboratory for treated and control seeds. The germination percent of greengram seeds was decreased from 98 to 60 as the ageing progresses from 0 to 10 days in case of neem oil treated seed and to 46 percent in untreated seed. Neem oil treated greengram seeds deteriorated slowly and also decreased in values of other seed quality parameters of aged seeds such as root length from 9.8 cm to 7.16 cm, shoot length from19.2 to 17.40 cm, Dry matter production from 444.02 mg to 195.66 mg and vigour index from 2842 to 1009. As a result, Neem oil treated seeds degraded relatively slowly than other seeds, demonstrating that it is effective in reducing the negative effects of ageing while maintaining vigour and viability.
