The application of growth regulators Gibberellic Acid (GA3) and Indole Acetic Acid (IAA) at panicle emergence stage/just at flowering stage affected the plant height, number of tillers per pot, sterility (%), number of spikelets per panicle and paddy yield significantly. Maximum reductions in sterility (%) was recorded in IAA and GA3 applied at panicle emergence stage as compared to check (control). The reason for this might be the delayed senescence and prolonged functionality of plant leaves, allowing the vital physiological processes of the plant like photosynthesis and translocating to carbohydrates for a longer period of time as compared to the pots where no growth regulator was applied.
