Dunal)” was conducted at Medicinal and Aromatic Plants Research Station, AAU, Anand during the year 2017-18. The objectives of the experiment were to identify the superior chemicals/growth regulators to obtain optimum germination and morpho-physiological parameters of Ashwagandha. The experiment was carried out under laboratory and field conditions. The laboratory experiment was laid out in completely randomized design while the field experiment was laid out in randomized block design. Each experiment consists of eleven treatments with three replications. The variety used for the present investigation was Gujarat Anand Ashwagandha – 1. The seeds were subjected to eleven treatments consisting of soaking in plant growth regulators, (GA3 and kinetin, each of 250 and 500 mg/l for 6 hours), cow urine (soaking with 6 and 12 hours), chemicals (NaNO3 and KNO3, each of 4000 and 8000 mg/l for 6 hours) and soaking in distilled water for 6 hours as control.EnglishThesis
