Effect of Gibberellic Acid on Growth and Seed Yield of Coriander (Coriandrum sativum L.)

Abstract

The experiment was conducted to study the effect of gibberellic acidon growth and seed yield of coriander (Coriandrum Sativum L.) cv. Hisar Sugandh and Hisar Bhoomit. In the present experiment, gibberellic acid concentration 50 ppm was used at three different stages of crop growth (seed soaking, spray at leaf stage and spray at 50% flowering). 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 growth, yield 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. 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. With the combination of Seed soaking + Spray at leaf stage + Spray at 50% flowering, the variety Hisar Sugandh found better for seed yield.
