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...

This article analyzes economic tradeoffs among harvest date, fertilizer applied, nutrient removal, and switchgrass yield as they vary with respect to input and output prices. Economic sensitivity analyses suggest that higher biomass prices lead to earlier harvest. Optimal harvest time occurs...
