Other names (PBR name, trademark, breeder code)
Oz-E-Green (protected by Australian Plant Breeder's Rights and United States Plant Patent), OZ TUFF® (registered trade mark of Robert Morrow)
The green couch variety selected from North Queensland is suitable for residential, commercial/industrial, parks and sportsfields. OZ TUFF® has shown to have improved wear tolerance than other turf species like blue couch and kikuyu and other green couch varieties. In a tropical environment additional fertility is required and integrated pest management (IPM) practices are warranted to keep couch mite under control, to achieve optimum turfgrass quality. Thatch production of OZ TUFF® is higher than other green couch varieties; however this provides protection of the crown (growing point) and reduces the occurrence of wear damage. Studies conducted by Australian Sports Turf Consultants to determine if growing ryegrass within the dense OZ TUFF® thatch layer was possible were successful. A dense ryegrass canopy was successfully grown even when applying the ryegrass seed using a Scott's SS-1 Professional Drop Spreader.
OZ TUFF® was ranked number 1 for its wear tolerance and recovery following wear studies conducted by the former Redlands Turf Research team for wear tolerance (Roche et. al, 2012). OZ TUFF® grows on a wide variety of soil types and can be watered with poorer quality water. Studies conducted by Poulter et al. (2010) from the Queensland Government identified that. OZ TUFF® continued growing within salinity levels at 30 dS/m (sea water is 54 dS/m). OZ TUFF® has a very short growing height and low level of inflorescence or seedhead production which helps to significantly reduce mowing requirements. OZ TUFF, Class 31, is a registered trade mark owned by Robert Morrow which has been protected since 15 Jun 2007 (trade mark no. 1180822) in Australia.
