| Outline of Final Research Achievements |
Flood- and drought-adaptive mixed cropping systems are effective in semi-arid regions. However, very few studies in crop science have focused on the environmental stress response of mixed crops. The objective of this study was to evaluate the stress response of mixed crops under various water conditions.
This study quantitatively showed that (1) the water condition in the early growth period affects the productivity of major crops in a semi-arid region, (2) mixed planting with pearl millet mitigates the drought stress of sorghum, and (3) mixed planting with rice mitigates the flood stress of soybean. In addition, the oxygen released from the rice root may mitigate the flood stress of upland crops, and the ability of oxygen release varies among cultivars.
