Effect of different orgopriming and foliar spraying treatments on seed yield and its components of coriander (Coriandrum sativum L.)

Coriander is one of the most essential spices in India. Coriander's extended germination period often delays crop establishment. The largest coriander-producing country, India must explore innovative agronomic practices to accelerate early growth and enhance overall productivity. So, a field experiment was conducted at Sagdividi Farm, Department of Seed Science and Technology, Junagadh Agricultural University, Junagadh, during the Rabi season of 2023-24 to evaluate the effects of orgopriming and foliar spray treatments on the growth and yield attributes of coriander variety Gujarat Coriander-3 (GC-3). The experiment was designed in a factorial randomized block design (FRBD), comprising six priming agents with control and three foliar spray treatments with a control, applied at 35 and 55 DAS (days after sowing). The results indicated that orgopriming with tender coconut water significantly increased field emergence by 25.37 %, plant height by 19.62 %, number of umbels per plant by 23.99 %, number of umbellate per umbel by 21.04 %, number of seeds per umbellate by 25.06 %, number of seeds per umbel by 19.58 %, 1000 seed weight by 12.04 %, seed yield per plant by 15.13 % and reduced number of days to 50 % flowering by 12.38 % as compared to control. Foliar spraying with Jivamrut (10 %) significantly increased plant height by 5.80 %, number of umbels per plant by 8.98 %, number of umbellates per umbel by 8.75 %, number of seeds per umbellate by 19.38 %, number of seeds per umbel by 12.02 %, 1000-seed weight by 8.57 % and seed yield per plant by 9.42 % compared to the control. The interaction of Bijamrut (10 %) priming and Jivamrut (10 %) foliar spraying produced the highest plant height with an increase of 40.48 % compared to control. Therefore, priming coriander seeds with tender coconut water and foliar application of Jivamrut (10 %) can enhance seed yield and its related traits.
