The purpose of this study was to investigate the effects of different plough rotation patterns on soil fertility, crop yield and income. The test treatments were six different plough methods of rotation mode. The results show that the best rotation model income suitable for the northern region was to plant forage corn without tillage in the first crop season, followed by green manure crop Sesbania aegyptica without tillage in the middle crop season, early maturing rice varieties in the second crop season, and wheat growing without tillage in the winter crop season. The net income reached NTD 56,970 per hectare.
