Under the conditions of the least inputs such as no-chemical fertilizer, no-chemical insecticide, and no-weeding, this experiment was carried out to examine the effect of mixed-seeding date on growth of hairy vetch and radish, and on the status of weed occurrence. Radish was severely damaged by insects during the whole growth period. Many summer annual weeds emerged and grew vigorously when the seeding date was August 14, but rarely emerged when the seeding date was August 28.
