| Outline of Final Research Achievements |
This study was conducted with the object of analyzing the possibility of cropping system in rice and soybean in Swamp which spreads in Indonesia. With a selection of resistant rice variety on iron toxicity and to revealed mechanisms on iron detoxification and absorption inhibition from QTL analysis. In addition, proposed to avoid failure due to flooding conditions effective fertility management practices. Furthermore we demonstrated a ratoon cropping system with high potential. To clarify the physiological mechanisms cause the salt injury in soybean, and usefulness of the salt tolerance of near-isogenic lines in revealed. On the other hand, the ｗithering of rice in acid soils was triggered by low pH and also discussed some of the causes of the formation of sulfate acidic soils.
