Optimizing Seed Priming Duration and Copper Levels for Coriander (Coriandrum sativum L.) Germination and Vigour

An experiment was carried out in the STR Laboratory, Jawaharlal Nehru Krishi Vishwa Vidyalaya, Jabalpur, MP, during the Rabi season of 2022–2023 to determine the impact of seed priming time and copper levels on seed germination and vigour characteristics of the coriander seedlings.

The experiment was laid out in completely randomized design (CRD) with three replications and 12 treatment combinations of Copper levels (0, 300, 400 and 500 ppm) and soaking duration (14, 16 and 18 h).

The outcomes demonstrated that priming treatments had a noteworthy impact on seedling germination and vigour traits. Significantly higher germination (82%), least mean germination time (7.9 days), maximum germination index (22.83), longest radicle (17.30 cm) and plumule length (13.09 cm), maximum vigour index-I (2374.05 cm) and vigour index-II (12.29 g) and lowest mortality rate (18%) was observed when seeds were primed with Cu @ 500 ppm soaking for 16 h. Success of crop production depends on quality of seeds and it’s germination percentage. Quality of seed susceptible to diverse climatic conditions resulting poor vigour and germination. Since availability of quality seed of coriander is very low, seed priming is an excellent technique which improves germination and better crop stand.
