Abstract: The investigation on the effect of seed priming treatment on cumin [Cuminum cyminum (L.)] seed germination and growth was carried out at Seed Technology Laboratory, Department of Genetics and plant breeding, SDAU, Sardarkrushinagar, during Rabi 2019-20. Seeds of Gujarat Cumin-1, Gujarat Cumin-2, Gujarat Cumin-3 and Gujarat Cumin-4 were were treated with five treatments viz., Control, -1.4 MPa PEG, -1.0 MPa PEG, 0.2% KNO3 and 0.4% KNO3. The experiment was laid out in a completely randomized design (factorial concept) with three replications comprising five treatment combinations. The combined effect of pre-sowing seed treatment and varieties showed a significant effect on seed germination and growth of the seedling. The variety GC-4 was superior to the variety GC-1, GC-2, and GC-3. The analysis of data collected under laboratory conditions for the variety GC-4 and treatment T3 (-1.0 MPa PEG) combination revealed characteristics such as the highest germination percentage (80.81%), the longest root length (5.20 cm), the longest shoot length (4.61 cm), the longest seedling length (9.59 cm), the highest seedling fresh weight (216.40 mg), the highest seedling dry weight (11.81 mg), the highest seedling vigour index-I (812.47) and the highest seedling vigour index-II (952.70).
