Tiftuf vs New Breeds: Why Tiftuf is the Superior Couch Grass
It’s understandable to become enthused about the arrival of any new turfgrass. As specialists in the field and lovers of turf, it’s ingrained in our DNA to show a keen interest in innovative turf products that are released to the market.
Like any product intended to make a profit, marketing and hype frequently ignore the distinguishing features that make a new product deserving of such high expectations.
Fortunately, as turf experts, we understand that the true test of a new turf varieties strength is in the data. Extensive, independent, and Australian based turfgrass testing and trials, this is where we find our diamonds. Without these trials and this conclusive data, all we are left with is hot air.
New Breeds
New breeds of grasses like TifTuf Hybrid Bermuda, have prompted a rise to a wave of aspiring grasses wanting to be just like TifTuf. It’s a remarkable grass, with a level of hype that has been rarely seen in the Australian turf industry, except for the likes of Sir Walter DNA Certified Buffalo. What TifTuf Hybrid Bermuda has that those other grasses do not, is data and lots of it.
While US data can provide an excellent guide and help turf researchers decide which grasses to import and trial, it’s not until there is Australian data from trials conducted in all parts of the country that claims of performance can be substantiated.
The Data
STRI (The Sports Turf Research Institute) conducts world leading testing and research, developing innovative techniques to assess and improve turfgrass surfaces.
STRI conducted the most recent Australian based independent trial evaluating the “Performance of Bermuda (couch) grass cultivars under different shade, irrigation, and wear treatments.” These trials included all the commonly grown couch grass varieties available across Australia.
TifTuf Hybrid Bermuda was a clear stand out performer in this trial outperforming all other couch grasses in every one of the treatments assessed.
TifTuf:
- Had superior turf cover (thickness and growth) over the duration of the trial compared to all other grasses trialled
- Scored the highest NDVI (normalised difference vegetation index) which is a measure of appearance using a specialised scanning device.
This was not a surprise to those who have been studying this grass for the best part of three decades. TifTuf has been trialled in the NTEP (National Turf Evaluation Program) in the US, where TifTuf was in the top 25% performing couch grasses for overall quality 84.6% of the time.
TifTuf vs Tahoma 31
Another newly introduced couch grass that has recently received some attention in Australia, managed to reach just short of 70%; that grass was Tahoma 31.
TifTuf outperformed Tahoma 31 significantly, showing its superiority as a better quality turf grass. Tahoma 31 has experienced limited expansion since it was introduced to the North American market, even though it was released around the same time as TifTuf. TifTuf has over 6,000 hectares currently in production across the US, with Tahoma 31 much less.
Superior Drought Tolerance
TifTuf has shown the same growth in Australia, where it has been formally recognised as Smart Drop Certified for water efficiency. After many years of extensive independent testing and research, TifTuf Hybrid Bermuda (Couch Grass) is the first and only turf grass to receive this for drought tolerance in Australia or anywhere in the world.
A study into water absorption of turfgrasses was conducted at the University of Oklahoma in 2019. This study found that when unlimited water was provided TifTuf absorbed more water than any of the other grasses in the trial. While this sounds like a negative, these results served to substantiate that TifTuf is indeed different when it comes to its relationship with water.
When water is available, it absorbs and utilises the resource available. When water is minimal or during deprivation, TifTuf has the capacity to withstand the strain before stress sets in, because when the water does come, it’s ready to make the best use of it.
An analogy used by leading turf breeding experts is this: TifTuf is the top dog, give it water and it will lap it up like crazy, but it will be able to run for days. While the other dog laps up the water with less exuberance, once released into the paddock, it’s the first one to falter.
TifTuf Is Certified
There is currently over 250 hectares of TifTuf in production in Australia, including at our Turfco farms, with production doubling year on year. All TifTuf turf is certified by AusGAP, the Australian Turf Certification Program, to maintain purity and integrity. There are no other new or existing Hybrid Couch grass varieties protected with this certification.
With the superior traits of these new varieties being paramount, maintaining genetic purity is of the utmost importance. When you choose TifTuf, you can be assured you are receiving the genetically pure turf variety that possesses the superior traits that resulted in its selection above all others.
