e1“Heavy (H) and light (L) fall (F) grazing intensities caused lower ( P < 0.05) grain yields compared to controls (C) in 1983 to 1984 (2.94[F‐L] and 2.53 [F‐H] vs. 3.51 [C] Mg ha −1 )”
e3“mixed results with fall‐only, spring‐only, and two levels of fall and spring grazing in 1985 and 1986 (2.41 [F‐L], 1.37 [S‐L], 1.80 [F,S‐L], and 1.46 [F,S‐H] vs. 1.90 [C] Mg ha −1 )”

Other claims from this paper (9)
- Intervention effect Light fall grazing lowered grain yield compared with controls in 1983 to 1984.
- Intervention effect Heavy fall grazing lowered grain yield compared with controls in 1983 to 1984.
- Intervention effect Spring grazing lowered grain production non-significantly in 1984 to 1985.
- Intervention effect Grazing decreased the number of spikes per square metre.
- Intervention effect Grazing lowered straw yields in all three years.
- Intervention effect Harvest index of grain was nearly always higher for grazed wheat.
- Association Weather differences affected grain production between years more than grazing stresses within a year.
- Observation Yield components were influenced inconsistently by the grazing treatments.
- Intervention effect Moderate grazing did not damage TAM W-101 grain yield when trampling was avoided.
