The primary purpose of this study was to find a morphological explanation for increased biomass in response to improved soil fertility in old stands of northern upland cultivars of switchgrass in the northern Great Plains and North Central USA. Therefore, requisite objectives were to determine the: 1) biomass yield response to N fertilizer in 10-yr-old stands of ‘Summer’ and ‘Sunburst’ switchgrass in the northern Great Plains and in a 5-yr-old stand of ‘Cave-In-Rock’ switchgrass in the North Central USA, and 2) relative importance of the causal morphological components as determinants of increased biomass yield in those stands.
