| Rice seed germination and seedling establishment of the vigorous seedling is an important juncture life cycle in plant, and it decides the success of crop cultivation. Static or pulse magnetic field exposure rice seed lots is known to change and stimulate the biological, and biochemical utilization. The current work aimed to enhance the rice seed germination, seedling establishment as affected by carry over seed and static or pulse magnetic field at initial germination, in addition the physiological mechanism of seed age, seedling vigor and competitiveness. The field experiment was conducted with two rice seed lots viz., fresh and old seed and five magnetic field treatments viz., T1: Control, T2: 50 (Millitesla) mT static 2 hours, T3: 50 mT 5 min 2 hours pulse, T4: 100 mT 2 hours static, and T5: 100 mT 5min 2 hours pulse. Results indicated that all measured parameters were over nonexposed. Highly significant differences among magnetic field treatments which exposure seeds to 50 mT for two hours performed better germination percentage and seedling length whereas, minimum was noticed under control. In respect of seed quality parameters, significantly higher seed germination, shoot length, root length seedling length, seedling dry weight, seedling vigour index 1, seedling vigour index 2, field emergence and proline content were recorded in the 50 mT for 2 hours in static and pulse. A highly significant correlation was obtained between vigour tests and field emergence. Magnetic field could be a promising technique to improve rice establishment and productivity with fresh and aged seeds. | ||||
