Abstract
To clarify the effects of cutting height and interval on stubble, root, and regrowth of palisadegrass (Brachiaria brizantha (A. Rich.) Stapf) cv. MG5 under a no ear emergence condition, we conducted pot experiments. The four cutting treatments combined two cutting height (10 and 20 cm) and two levels of cutting interval (2 and 4 week) and a control plot without cutting were prepared. The growth rate of more than 5 cm from the ground, aboveground biomass of less than 5 cm from the ground, the underground biomass, and the number of stems were investigated. Results show that, from four weeks after first cutting, the growth rate, the aboveground biomass and the underground biomass of the control showed maximum values. Those of 10 cm and 2 week treatment showed minimum values. A higher cutting height and a longer cutting interval increased the growth rate, the aboveground biomass, and the underground biomass. Decrease of the aboveground biomass and underground biomass of 10 cm and 2 week treatment suggest that palisadegrass is unsuitable for low height and frequent cutting.
