| Outline of Final Research Achievements |
Tree growing paddy field in tropical Asia where the number of trees has been reducing in paddy floor but are increasing on levee, has still an important role as providing materials for livelihood in tropical rain-fed rice growing villages. It should be noted that some kind of planted trees become obstacles for rice yield. Termites and their mounds are also contributing to agricultural production and village life. The fertile soil of mound is made by the interaction of termite activity with tree growth on the mound. Digging and removing whole mound in paddy field become popular for celery production in Thailand, however, mounds will disappear after 10 years there. Some villagers are using mound soil for manure taking care of regeneration of mound. Digging in small part of outer wall of mound stimulates regeneration by termites according to an experiment. It should be payed attention that extremely poor growth of rice is caused on the site after mound removing in paddy field.
