Abstract:
Coriander is a vital spice crop in India, but its prolonged germination often delays crop establishment. As the world’s leading producer, India must adopt innovative agronomic strategies to enhance early growth and overall productivity. To address this, two experiments-one in the laboratory and one in the field were conducted during the Rabi season of 2023–24 at the Seed Testing Laboratory and Sagdividi Farm, Department of Seed Science and Technology, Junagadh Agricultural University, Junagadh. The study aimed to evaluate the effects of orgopriming and foliar spray treatments on seed quality, growth and yield of the coriander variety Gujarat Coriander-3 (GC-3). Six seed priming treatments were tested under both lab and field conditions, while the field experiment also included foliar spraying treatments as a second factor. Among priming treatments, tender coconut water significantly enhanced germination (81.25%), root length (6.08 cm), shoot length (8.31 cm), seedling length (14.39 cm), seedling fresh (397.70 mg) and dry weight (32.18 mg) and seedling vigour indices (1168.97 and 2614.51). In field performance, it also improved field emergence (82.33%), plant height (76.39 cm), number of umbels per plant (20.88), umbellets per umbel (8.17), seeds per umbellet (10.68), seeds per umbel (61.44), 1000-seed weight (12.56 g), and seed yield per plant (12.48 g) and led to earlier flowering (50.50 days). Among foliar sprays, Jivamrut (10%) significantly increased all growth and yield parameters compared to the control. The highest plant height (80.97 cm), with a 40.48% increase over control, was recorded with the interaction of Bijamrut (10%) priming and Jivamrut (10%) foliar spray. Thus, seed priming with tender coconut water and foliar spraying with Jivamrut (10%) can substantially improve the seed quality and yield of coriander.
