Research interests

My research interest is firstly mechanisms of crop production in relation with resource utilization, responses to climate, and adaptation to abiotic stress under various environmental and managemental conditions. I am currently working on crop production with relation to symbiosis with arbuscular mycorrhiza under different environmental and managemental conditions.

My second research interest is diversity and heterogeneity of agroecosystems in both large and small scales. The heterogeneity of agroecosystem within a target area is small scale environmental variation, which would be related with success and failure of extension of new technologies, becoming as a source of gap between farm yield and potential yield. I have been investigating diversity of rice ecosystems such as rainfed lowlands, deepwater rice, tank irrigation rice, delta rice, and taipa rice.

My third research interest is sustainability science. Sustainability has social component, and sustainable agriculture cannot be attained where social injustice prevails. Extension of technologies can be studied as a decision of how to utilize new and traditional technologies, including perception of people.
