Abstract:

Two different clones of Giant reed (Arundo donax L.) were compared over 8 years (2004­2011) for crop yield, energy and greenhouse gas balances. In Extremadura Region (Spain), three different irrigation treatments (100% Etm restoration, 50% Etm restoration and no irrigation), and two clones (local clone and Rabuiese) were evaluated in a split­plot experiment. In the eighth year of the field experiment (2010­2011) no irrigation was applied in all treatments. Results showed high above­ground biomass yield over a period of 8 years for Giant reed even in no irrigation plots (23.4 t ha­1 of dry matter on average for local clone). The highest crop dry yield was for the local clone and 100% Etm restoration (34.0 t ha­1). Moreover, Arundo donax L. is characterized by a positive energy and greenhouse gas balances. Results confirm high Giant reed biomass yield and favourable energy and greenhouse gas balances, even in cultivation characterised by limited water input.
