EFFECT OF FOLIAR APPLICATION OF GIBBERELLIC ACID ON SEED SET AND YIELD CONTRIBUTING CHARACTER IN HYBRID RICE

摘要

A study was conducted to see the effect of foliar application of gibberellic acid on seed set and yield contributing characters in hybrid rice. The results indicated that there was significant differences between the treatments for various characterswith GA_3 application. There was significant increase in panicle bearing tillers plant panicle length, no. of spikelets per panicle, spikelet fertility, test weight, panicle exsertion, grain yield with each increment of GA_3 application upto 100 g/ha. Although higher doses of GA_3 application increased panicle exsertion. outcrossing percentage and seed yield/plant.
