Abstract
The growth and yield of rice plants cultivated without puddling and levelling (NP) were compared with those of rice plants grown under a conventional tillage (CT) condition. There were differences in the tillering number, plant height, and leaf color between rice plants grown in NP and CT conditions. The rate of exudation from rice plants in NP was higher than that in CT conditions at the late growth stage. However, the yield of rice plants in NP was lower than that in CT, and the studies on cultural practices, such as plant spacing and the application rate and timing of fertilizer are necessary to acquire a high yield with a high quality under the NP condition.
