Technical Abstract: Elephantgrass (Pennisetum purpureum Schumacher) is a tall tropical bunch grass that produces high enough yields to being considered an excellent bio-energy feedstock for the lower South. However, previous studies have shown that production is not sustainable without fertilizer application and adequate soil moisture. The objective of this study was to determine the effects of N (three levels) and K (two levels) fertilizer and irrigation on ‘Merkeron’ elephantgrass at Shellman, GA. The yield one year after establishment did not vary among fertilizer treatments but was significantly greater for plots receiving 1.1 cm irrigation wk-1 (29 kg ha-1) versus rainfed (21.7 kg ha-1). Second year yields did not vary among fertilizer applications but was higher for 2.2 cm (35.4 kg ha-1) and 1.1 cm (33.4 kg ha-1) irrigation wk-1 versus rainfed (26.4 kg ha-1).
