Projections of future climate change include a strong likelihood of a doubling of current atmospheric carbon dioxide concentration ([ CO 2 ]) and possible shifts in precipitation patterns. Drought stress is a major environmental limitation for crop growth and yield and is common in rainfed rice production systems. This study was conducted to determine the growth and grain yield responses of rice to drought stress under [CO 2 ]...

Future climate change is projected to include a strong likelihood of continued increases in atmospheric carbon dioxide concentration ([CO 2 ]) and possible shifts in precipitation patterns. Due mainly to uncertainties in the timing and amounts of monsoonal rainfall, drought is common in rainfed rice production systems. The objectives of this study were to quantify the effects and possible interactions of [CO 2 ] and drought st...
