About

I have always been interested about soil-plant interactions. An alarming rate of groundwater depletion is a major threat to future rice production throughout Asia, especially in India and China. Rice has evolved from a semi aquatic ancestor and has kept better adaptation to semi aquatic environments than to aerobic environments. Thus, rice crops generally suffer a yield penalty in aerobic soil when compared with flooded conditions.

In our team, we focused on variability in the rate of leaf appearance, caused by different watering conditions. Our working hypothesis is that this modification of leaf appearance rate is not just a simple consequence of the watering conditions among many others. On the contrary, this modification of leaf appearance rate would be the main trigger of many changes induced in the crop canopy by the different watering conditions.

Testimonial

In China, farmers are pressed for scientific and flexible water managements. These maintain yields and improve soil health. In water-save tillage systems, conventional tillage is replaced by AWD management, aerobic management, etc. Effects of water-save on rice and soil health are still unclear. The International Rice Research Institution (IRRI) is one of the authoritative institutions in rice research and is highly reputable worldwide. I believe that learning the concepts and methods of Long-Term Continuous Cropping Experiment (LTCCE) and water management in IRRI will help us improve future research.
