Influence of Various Seed Priming Techniques on Coriander's (Coriandrum sativum L.) Plant Growth

Abstract

The field experiment was conducted at the Vegetable Research Farm, Chandra Shekhar Azad University of Agriculture and Technology, Kanpur, Uttar Pradesh, India, during the Rabi seasons of 2023-24 and 2024-25. This study examined the impact of various seed priming techniques on the growth parameters of the Coriander variety Azad Dhania-1. A randomized block design was used in this experiment with three replications. The following treatments were used for the study, viz. T0- Control, T1- hydropriming for 24 hours soaking, T2-Vermi wash 15% for 24 hours soaking, T3- Cow urine 20% for 24 hours soaking, T4- Panchgavya 15% for 24 hours soaking, T5-Humic acid 20% for 24 hours soaking, T6-GA3 50 ppm for 24 hours soaking, T7-NAA 50 ppm for 24 hours soaking, T8- Cytokinin 100 ppm for 16 hours soaking, T9- KNO3 3% for 16 hours soaking, and T10-NaCl 0.5% for 16 hours soaking. The best results were obtained in T5 for field emergence 83.33 % (65.90), days to 50% flowering (88.50 days), plant height (114.19 cm), and Days to Maturity (127.33 days). The lowest field emergence (71.00%) was observed in T8, while the highest days to 50% flowering (95.50 days), days to maturity (131.50 days), and lowest Plant height (101.54 cm) were observed in T0-Control in the pooled.  According to the findings, priming with humic acid and then Panchgavya and KNO3 will promote higher emergence (%), plant height and early flowering while shortening the maturity period.
