Weed control is one of the important and difficult practices in environment-sound agriculture. This study was conducted to establish environment-sound weed control in paddy fields using rice bran pellet. Application of rice bran pellet at a rate of 13 Mg reduced weed occurrence by 4669% without using any chemical herbicide. However, rice bran application at a rate of greater than 2 Mg increased protein content in milled rice and decreased palatability value. Therefore, fertilization rate before transplanting needs to be reduced from = 55-45-40 kg to 28-23-20 kg , in order to decrease protein content and increase palatability value without decreasing rice yield. Pyroligneous acid and brown rice vinegar had a relatively weak activity to inhibit weed emergence compared with rice bran. When butachlor herbicide was applied at a rate of 0.75 kg , 50% of recommended rate, co-application of rice bran pellet at a rate of 1 Mg enhanced weed control value from 63% to 75%.
