EVALUATION OF WEAR DURING WINTER DORMANCY ON THE ROTATIONAL TRACTION OF HYBRID BERMUDAGRASS
Due to a prolonged drought (1997-2009),many sportsfields in southeastern Australia were converted from C3 grasses to C4 grasses,which includes hybrid bermudagrass (Cynodon dactylon (L.) Pers.x C.transvaalensis Burtt Davy).The ability of hybrid bermudagrass to provide adequate traction after wear was unknown,especially during winter when it was in dormancy.Therefore,two field trials were conducted to quantify rotational traction at increasing levels of simulated traffic and groundcover depletion,one in summer and the other in winter.The results were similar in each case.Peak torque exceeded 80 Newton-metres (Nm) with full or nearfull grass cover,and was reduced as groundcover was depleted by simulated traffic.However,peak torque was still within an acceptable range of 43 to 55 Nm even when the turf surface was worn to within 2 - 7% groundcover.Although such a badly worn surface may not be aesthetically desirable,the field trials demonstrated that hybrid bermudagrass can provide adequate traction with severe groundcover depletion,even in winter.
