The experiment was conducted in field and laboratory at Department of Genetics and Plant Breeding, Naini Agricultural Institute, SHUATS, U.P. during rabi season 2020, in order to standardize the best method of priming specific to tomato (var - Pusa Ruby). Tomato seeds are treated with same intensities of Magnetic field 100 mA for different durations i.e (1min, 5min and 10minutes), different intensities of electric field (100 mA, 125 mA, 150 mA for 1 min) and the combination of Magnetic(100 mT) + electric(100 mA for 2 min), Magnetic(100 mT) + electric(125 mA for 2 min), Neem leaf extract (3% for 7 hr), Cow urine (25% for 7 hr), Panchagavya (3% for 7 hr and 5% for 7 hr). It was found that all the treatments showed a significant difference with the control. In the present investigation T4 – Electric field treatment (100mA) exposure of 1 minute performed best results in field parameters like plant height (cm) 90 DAT, days to first flower initiation, number of flowers per cluster, days to first fruits set, number of fruits per cluster, number of fruits per plant, days to maturity, fruit weight (g), fruit yield per plant (kg), number of seeds per fruit, 1000 seed weight and in lab parameters like germination percentage, shoot length, root length, seedling length, fresh weight, dry weight, seed vigour index - I and seed vigour index - II followed by T6 – Electric field treatment (150mA) for 1 minute and T9 – neem leaf extract (3%) for 7 hours.Hence seed treatment of tomato seeds with electric field is the best treatment when compared to magnetic field and other pre-sowing seed treatments.
