Switchgrass (2 of 3)

Caption

This plot shows the yields of three switchgrass varieties, or cultivars -- Kanlow, Cave-in-Rock and Southlow -- and a mixture of the three. The mixture is either the highest yielding or approximately equal to the highest yielding crop each year, closely following the Southlow crop in 2014. These measurements are from plots without added fertilizer (nitrogen inputs).
