Abstract: The experiment was conducted to study the effect of gibberellic acid on seed quality of coriander (Coriandrum Sativum L.) cv. Hisar Sugandh and Hisar Bhoomit. In the present experiment, gibberellic acid concentration 50 ppm was sprayed at three different stages of crop growth (Seed soaking, Spray at leaf stage and Spray at 50% flowering stage). Gibberellic acid was sprayed in eight treatment combinations of three stages. Based on the experimental results, it was concluded that application of gibberellic acid improved the quality of coriander seeds. Test weight, germination percentage, Seed vigor index-I and Seed vigor index-II were observed maximum with (Seed soaking+ Spray at leaf stage+ Spray at 50% flowering stage) followed by (Spray at leaf stage+ Spray at 50% flowering stage). Among both the varieties, the variety Hisar Bhoomit found better for germination per cent while Hisar Sugandh performed better for test weight, vigor index.
