Description
Low inputs and sustainability are the major concerns in bioenergy crop production (Reijnders 2006). Erianthus spp. is a relative of sugarcane and is a perennial crop with high dry matter production (Matsuo et al. 2003). It is expected to become a cellulosic bioenergy crop. However, its fertilizer requirements are still unknown because erianthus has a highly developed root system (Matsuo et al. 2003), and appears to absorb nutrients from the subsoil layer, which is hardly used by other crops. Therefore, it is necessary to experimentally restrict fertilizer application and maintain the rhizosphere to clarify the fertilizer requirements.
In this study, we grew Erianthus (Erianthus arundinaceus) in pots and restricted nitrogen (N), phosphorus (P), and potassium (K) fertilizer application to evaluate the fertilizer requirements.
