Outline Activities
“Understanding the ecophysiology of tropical crops and its application for agricultural production.” My research focuses on tropical and subtropical crops (mainly yams and rice) to elucidate eco-physiological traits that can contribute to improved agricultural productivity, and to establish new cultivation systems based on them. In addition, through international joint research with Vietnam and other Southeast Asian countries, we are involved in development of new crop varieties adapted to local environment and in creation of high crop production systems. By promoting tropical crop science research, we would like to give back the results obtained to agriculture in tropics and subtropics in the future.
