Orchardgrass Grazing Response Dr. Ray Smith Laura Schwer Tom Keene

Methods Two similar orchardgrass plants were chosen from greenhouse. Both were managed the same for 6 months: Clipped ~once per month Supplied with good fertility (N,P, K) and water  

Methods Left plant simulates continuous grazing. Initially clipped to a 1 inch height Then clipped weekly for the next 4 weeks at a 1 inch height Right plant simulates rotational grazing. Initially clipped to a 3.5 inch height Then clipped again at 3.5 inches four weeks later Time lapse photography started at the beginning of the fifth week (day 29) for both plants. 

Day 1 (24 hours after clipping) 1” Continuous 3.5” Rotational

Day 2 1” Continuous 3.5” Rotational

Day 3 1” Continuous 3.5” Rotational

Day 4 1” Continuous 3.5” Rotational

Day 5 1” Continuous 3.5” Rotational

Day 6 1” Continuous 3.5” Rotational
