Abstract

Barnyardgrass (Echinochloa crusgalli (L.) Beauv.) emerged in fields as early as May 3. The shortest period between seeding and emergence and between emergence and tillering was during the warmest period of the growing season. The number of days from emergence to heading and maturity decreased progressively for later seedings. The height of plants was greatest when the plants emerged early in the growing season. The highest number of tiller and heads per tiller were produced by plants emerging in July. Plants which emerged in May and June produced the highest yields. Barnyardgrass seedlings grown under 11-hr photoperiod and 16-hr photoperiod produced mature seeds in 52 and 84 days, respectively. Barnyardgrass grew best under wet soil moisture conditions.
