More than sixty percent of the world’s population eats rice as staple food, making it both the most significant food in terms of human nutrition and calorie consumption. Poor field germination capacity, imminent water constraints, rising labour expenses and the continuously growing world population force us to make a better decision in order to ease the food crisis and increase rice output. For increasing seed vigour, synchronising germination, fostering the growth of seedlings, and increasing yield in a variety of crops, seed priming is an effective and useful technique. Pre-soaking seeds before planting encourages quick germination and growth, especially under difficult environmental circumstances. Abiotic stresses like drought, salinity, heat, cold, and heavy metals are commonplace for plants and cause complex reactions that lower crop yield and growth. It is commonly known that phytohormones regulate the growth and development of plants. They are also crucial chemical messengers that enable plants to function when they are under a variety of stressors. Through seed priming, plants can develop a greater ability to quickly and efficiently withstand a variety of stresses. So, phytohormones as seed priming have become a crucial strategy for reducing the negative effects of abiotic stress. Keeping these points in view, the present study was carried out with phytohormone priming materials. The research programme was formulated with seven priming materials on laboratory conditions with the objective of optimizing the appropriate concentration of GA3 and Kinetin for better performance. Distinct findings were noted like germination parameters, different vigour and seedling parameters. Highest germination percentage (98.33), Vigour index-I (2599.933), and Vigour index-II (1445.767) was observed in 50 ppm GA3. Seed priming with 50 ppm GA3 was found very effective for seed germination, vigour, and seedling parameters. So, from this experiment, 50 ppm GA3 was superior executant hormonal priming as it enhanced seed yield and most of the prime yield attributes.

Phytohormone priming of seeds breaks dormancy and increases viability, ensuring hermonized germination. For rice, seed priming with phytohormones has become a successful seed treatment technique; however, there are still limitations to this approach, and treatment conditions and techniques vary from phytohormone to phytohormone. For instance, if seeds are exposed to a hormonal solution for an extended period of time during priming, they may lose their ability to withstand desiccation, which lowers their viability. The primed seed with GA @ 50 ppm had the best germination, vigour, and seedling characteristics among all the priming materials. It could therefore be chosen as the hormonal priming material with the best performance. The beneficial effects of GA @50 ppm on germination, seedling growth, and development were noted; these findings may be the main reason to recommend seed priming with GA @ 50 ppm for the establishment of rice crops.
