seems that crop elevation also has effects on bioenergy crops- production at lower levels of sugar cane and energy cane crops is almost double than napier/napier hybrids. Whereas it's the opposite at higher levels. limited higher levels that remain frost free year may be a difficult, as well as a small market

Biomass yield was collected from 2011 to 2013. Sugarcane was harvested once. Energycane was harvested once a year and included one ratoon. Napier and napier hybrids were harvested every six months and included three ratoons. At elevations 90 and 305 m, sugarcane and energycane biomass yield were similar ranging from 72.8 to 82.0 Mg ha-1, but significantly greater than napier/napier hybrids at 49.1 to 53.8 Mg ha-1. At 915 m elevation, napier/napier hybrid yield was 52.4 Mg ha-1 and significantly greater than sugarcane and energycane yield at 24.9 and 28.9 Mg ha-1. The data indicate that sugarcane and energycane yield well in the lower elevation and napier/napier hybrids have the yield advantage at higher elevations.
