Phosphatase plays an important role in availing plant P from organic P sources but knowledge on this soil property, particularly in paddy root zones, is limited. This research was to evaluate activity of phosphatase in the root zones of paddy plants in different planting systems (direct seeded and replanting) employing pre-emergence herbicides. Even though the growths of paddy plants and weeds were greatly affected by herbicide treatments, the activity of acid phosphatase in the root zone of paddy plants was not influenced by weed management techniques. The direct seeded system was also not different with the replanting system in affecting the activity of acid phosphatase, except that the activity of acid phosphatase tended to be greater in the root zones of paddy plants in the replanting system when herbicides were applied.
