Studies were made to traceout the relationship between seed size and duration of acid scarification in tamarind seed for removal of hard seededness without affecting the quality of seed, The experiment was formulated with different size grades (27/64", 25/64" and 23/64" round perforated metal sieve) and various durations (20, 15 and 10 minutes) of acid scarification with commercial sulphuric acid @ 200 ml kg of seed. The study revealed that seed size and durations of acid scarification are positively related, where bigger sized seed require 20 minutes of acid scarification while it reduced to 15 and 10 minutes with medium and smaller sized seeds, respectively.
