Russian wildrye plants were clipped at all possible combinations of three clipping dates (April 15, May 15, June 15) at two intensities (35 and 65% harvest of current year's growth). From 1974-1977 increasing frequency and intensity of defoliations increased total biomass removed over the 4-year period. There was no trend for reduced yield over time with any clipping treatment. However, percent plant crown alive (1976-1978) and end-of-season standing crop (1978) both indicated that increasing frequency and/or intensity of defoliation decreased plant vigor.
