Impact of Nitrogen and Phosphorus Applications of Three Bioenergy C4 Crops on Biomass Production and Nutrient Balance

G. Siri Prieto
Arundo donax L. (Arundo D.) Pennisetum purpureum (Elephant G.), and Panicum virgatum (Switchgrass) are three perennial C4 crops which have been received particular attention during the last years as bioenergy crops. The experiment located in Uruguay, were established in 2007 to determine biomass production and nutrient balance on these three energy crops. A combination of four treatments of N and P (0 or 100 kg ha­1) were applied annually. Elephant G. yielded significantly more biomass...
