Recently with increase tendency of direct sowing cultivation, lodging problem which affect to the high quality rice plant is again raising its ahead. In order to reduce this lodging problem there is a chemical method which uses plant growth retardant. This experiment was conducted to evaluate the effect of lodging reduction as affected by plant growth retardant which is IBP-Metconazole (IPM) in direct-seeded rice on flooded paddy field. IPM treatment carried out 50, 40, 30 days before heading. Hexaconazole treatment carried out 30 days before heading. IPM treatment 30 days before heading resulted the shortest plant culm among the IPM treatments. 4 internode length was shorter by 3.75㎝ in IPM treatmenst than in control. breaking strength was not a difference from between IPM treatments but breaking strength was significantly increased by IPM treatments than control. IPM treatments increased yield 10~11% as compared with control. The protein contents of flag leaves by 2-DE were visually higher in the plot treated with the IPM application than in the plot control plot. The proteome approach to elucidate the mechanism which inhibited gibberellin synthase will be future performed in the on-going research.
