Outline of Final Research Achievements

This study aimed to evaluate the effect of no-paddling to the soil physical and chemical properties of upland field converted from paddy field, and assess the change of soil properties to growth and yield of soybean. The no-paddling improved the soil physical and chemical properties of upland field converted from paddy field such as water permeability, fertility and soil tilth. The leaf expansion, leaf color and dry matter production of the soybean grown under the field after no-paddling paddy field were superior to that grown under the field converted from paddy with paddling. The yield of soybean increased by 11.1% in the upland field converted from no-paddling paddy field. These results showed that the no-paddling was effective to improve soybean production under rice－soybean crop rotation system.
