Switchgrass (panicum virgatum L.), a viable option for second-generation renewable fuels, has an extended harvest window with optimal harvest affected by yield, storage losses and nutrient uptake. This research shows that optimal harvest occurs later than maximum yield for Haskell, OK and Fayetteville, AR with different fertilizer and switchgrass prices.
