Yield Potential and Nitrogen Requirements of Miscanthus × giganteus on Eroded Soil

Core Ideas Miscanthus’s performance on eroded claypan soils was comparable to other more productive soil. Only 4 of 12 site‐year combinations required fertilizer N to maximize Miscanthus yield. Nitrogen priming had no benefit and the constant rate of 67 kg N ha −1 yr −1 was the lowest that maximized total yield. Relative leaf chlorophyll concentration in June is a reliable indicator of yield response to N. Miscanthus × giganteus yield and...
