Effect of annual grass weeds in alfalfa establishment, yield and forage quality

Weeds can affect alfalfa establishment, productivity and forage quality but the magnitude of the impact has not been thoroughly studied. Over the past three years we have established studies to evaluate the impact of all of these factors during the establishment year as previous research has shown this to be the most sensitive to weed populations. While previous experiments have been conducted throughout the state, research in 2014 was focused at the Arlington research station to determine the impacts of annual grasses on alfalfa establishment.
