The experiment was conducted at the International Rice Research Institute (IRRI) Farm, wet season. Aqueous solutions of 10,1000 and 500 ppm of IAA, NAA and 100 ppm of GA3 and 2, 4-D were sprayed at the rate of 300 liters of spray volume per hectare at flowering and late milk stage. The application of IAA, NAA, GA3 and 2, 4-D to the main crop at 10,100 and 500 ppm during the flowering and late milk stages had no beneficial effects on ratoon rice.
