Abstract
Enteropogon ramosus is a summer-active (C4) native grass species found throughout Australia. It is a useful pasture species in some regions, but may adversely impact winter annual crop yield. Research was conducted into the emergence, survival and seed production of this species over 2 years, in a pasture-pasture or pasture-wheat rotation, in the Western Australian wheatbelt. Within the continuous pasture system, Enteropogon ramosus grew and set seed throughout the year. Minimum tillage cropping did not prevent growth or seed production of this weed, and wheat yield was reduced (21%; from 1.31 to 1.04 t haí1 ) through weed competition. However, a single cultivation event at the beginning of the 2 year research programme was sufficient to reduce emergence and prevent seed production by E. ramosus in both the pasture and wheat crop phase. Enteropogon ramosus is clearly a weed favoured by the minimum tillage system, and so in the absence of disturbance, herbicide options are required to control this species in wheat.
