Abstract:
Present investigation was carried out to study the “Effect of seed priming on germination and phenology of rice under anaerobic condition” during wet season, 2016-17. Experiment was laid out in randomized block design with three replication and two varieties Sambha Mahsuri and Sambha Mahsuri <em>Sub1</em> in<em> </em>cemented pond (size; 20×20×1.25 meter). Primed seeds were direct seeded and field was completely submerged/ flooded, upto 25-30 cm water depth was maintained for one month. Recommended dose of N, P and K @ 120:40:40 Kg ha<sup>-1</sup> was reframed with time schedule. Treatments comprised of (T<sub>1</sub>) Seed priming with GA<sub>3</sub> @ 25 ppm, (T<sub>2</sub>) Seed priming with GA<sub>3</sub> @ 50 ppm, (T<sub>3</sub>) Seed priming with JLE @ 2%, (T<sub>4</sub>) Seed priming with KNO<sub>3</sub>@ 0.5%, (T<sub>5</sub>) Seed priming with KCl @ 0.2%, (T<sub>6</sub>) Seed priming with NaCl @ 0. 5 %, (T<sub>7</sub>) Seed priming with IAA @ 0.2 %, (T<sub>8</sub>) Seed priming with CaCl<sub>2</sub> @ 0.1 %, (T<sub>9</sub>) Control with distilled water.Results indicated that all the priming treatments increased the germination percent, speed of germination, days to 50% flowering and days to physiological maturity however, effect of GA<sub>3 </sub>@ 50 ppm was found more pronounced on various parameters in both the variety but Sambha Mahsuri <em>Sub1</em> showed more response of seed priming as compared to that of Sambha Mahsuri.Seed priming with various chemicals and its concentration may be used as a tool to mitigate the adverse effect caused by anaerobic condition in rice or direct seeded rice early flooding in recurrent phenomena.
