In the present investigation, seeds of Nigella sativa were subjected to various treatments to achieve early germination by breaking dormancy. The highest germination percentage for N. sativa seeds (93%) was achieved with pre-soaking treatment for 6 hours. It was followed by 84% with IAA. The seeds kept as control germinated to the tune of 59%. The scarified and GA3 treated seeds exhibited 55% germination each, whereas thiourea, H2SO4 and hot water treated seeds showed 45% germination each. The stratified seeds, those subjected to alternate high and low temperature, KNO3, mechanically injured and those subjected to electric current, coumarin and brassinolide showed 46%, 42%, 33%, 51% , 31%, 31% and 75% germination respectively. Thus, for achieving higher germination percentage of N. sativa, pre-soaking of the seeds for 6 hours is the best option.
