Projected annual average harvestable yield of M. x giganteus in the third year after planting based on weather data for each of the past 30 years, and soil moisture and soil depth gridded across the 48 contiguous states. [Figure courtesy of Fernando Miguez and Germán Bollero using a model parameterized as described previously] Projections agreed closely with prior measurements. After planting, annual average harvestable yields would be expected to increase for the first 3 years and then remain more or less constant for several further years (10, 27). In contrast to maize, projected yields are higher to the south and east of the cornbelt.
