The effects of tillage in autumn and spring, straw mulching and fertilization on weed communities were investigated in paddy field experiments in which the four treatments were repeatedly conducted from 1964 to 1967. Tillage treatments affected on the amounts of Alopecurus aequalis and Lobelia chinensis. The amounts of Alopecurus aequalis decreased considerably in plots where non-tillage were assigned in autumn and spring. Lobelia chinensis was remarkably supressed by the tillage treatment in autumn. And, it propagated well under the low fertilization level. Rice straw mulch affected only on the amount of Polygonum lapathifolium and decreased it. It was considered that herbicides used (paraquat and simazine) were very effective to Alopecurus aequalis under non-tillage condition.
