Abstract: The experiment was conducted in Post Graduate Laboratory, Department of Seed Science and Technology, Acharya Narendra Deva University of Agriculture and Technology, Kumarganj, Ayodhya-224229. U.P. during Kharif 2017 & 2018 in order to standardize the best method and or doses of priming in three cultivars viz., NDR-2064, Shusk Samrat and Shabha Sub-1 of rice. Dry (Moisture, 11-12%) and uniform seed of all three varieties were subjected to GA3 @ 200 and IAA @ 50 ppm (hormonal priming), KNO3 @ 200 ppm and KCL @ 200 ppm for 12 and 16 hrs. in Completely Randomized Design with three replications. Untreated seed of each variety was served as respective control. It was found that all the priming treatments enhanced significantly seed quality parameters viz., seed germination (%), speed of germination, root length (cm), shoot length (cm), seedling length (cm) and vigour index in comparison to their respective control. These seed quality parameters were significantly enhanced with hormonal priming (GA3 @ 200 ppm) followed by halopriming (KNO3 and KCL @ 200ppm) irrespective of the all three cultivars over 12 and or/16 hrs of priming. These seed priming treatments being cost effective and comparatively eco-friendly need to be exploited for befitting the rice cultivation.
