| Research Abstract |
Direct-sowing culture of paddy rice using non-woven fabric mulch is a new rice cultivation method in Japan. This technique was purposely developed for environmental conservation, low cost, weed control, and save labor, but it remains to be improved. This research was done to mechanize the application of the rolled mulch on the field, increase the work efficiency, and reduce the work load of the farmer. Multiple-laying system using a tractor and press roller for seedling establishment were manufactured and verified. Furthermore, research on the application amount and timing of nitrogen topdressing to increase in the grain yield were also investigated.
