Abstract
The experiment entitled “Effect of gibberellic acid on seed production of coriander (Coriandrum Sativum L.) was conducted during Rabi season of 2016 -17 at Research Farm of the Department of Vegetable Science, CCS Haryana Agricultural University, Hisar. The seed material used for the investigation was varieties Hisar Sugandh (DH-36) and Hisar Bhoomit (DH-228). 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). Sixteen treatment combinations laid out in Randomized Block Design were replicated thrice making total of 48 plots. Based on the experimental results, it was concluded that application of gibberellic acid improved the growth, yield and quality of coriander seeds. Seed soaking + Spray at leaf stage + Spray at 50% flowering stage was the right combination for gibberellic acid application to improve the growth and yield of coriander and the quality of coriander seed. In case of spray at two stage, (Seed soaking + Spray at leaf stage) was the right combination to improve the biological yield, whereas, (Spray at leaf stage + Spray at 50% flowering) was the right combination to improve the seed yield and quality like test weight, germination (%), vigor index-I and vigor index-II. With the combination of Seed soaking + Spray at leaf stage + Spray at 50% flowering, the variety Hisar Sugandh found better for seed yield.
