Japanese millet (Echinochloa utilis Ohwi et Yabuno) is a promising rotational feed crop for poorly drained fields. Methods were studied for preventing millet from becoming a weed. 1) Fields at the heading time have individual plants bearing seeds capable of germination due to maturation rate differences. Seeds from those individuals are likely become weeds during the next crop rotation. 2) Although Japanese millet cut during the period between boosting stage and heading included plants that had become weeds, cutting during this growth period can prevent conversion. 3) It is feasible to cut medium-maturing and late-maturing 'Green Millet' at a time suitable for harvest after the rainy season, which is the growth period when there is no concern about the conversion. Suitable varieties are available for Toyama Prefecture. 4) A combination of cultural practices and herbicide control is more effective than cut during the growth period alone for preventing Japanese millet conversion to weed.
