Mixtures 1 and 2 (Fig 1) show the excellent performance achieved with the use of innovative species, allowing for adequate establishment time. Mixtures 3 and 4 are more commonly used for stadium pitches either as seed or turf. The results revealed that innovative species can offer improved performance in these conditions. Although these slower-establishing species may not be considered as a choice for overseeding for short renovation windows, they can

be either custom grown as turf for renovation (available from accredited growers) or used in a seed mixture for new constructions. Rooting depth capability is important for stabilisation and for healthy plant growth, but root mass near the surface is also important to minimise divoting and scars. Tall fescue has a deep rooting capability and is naturally more adapted to growing in these conditions. RTF (rhizomatous tall fescue) also has the added value of producing rhizomes for both recovery

and tensile strength. Tufted hairgrass is naturally adapted to shade and has the capability of producing a very dense root system.
Individual cultivars within a species also exhibit significant differences, in this instance perennial ryegrass. For perennial ryegrass (Fig
2), the trial also demonstrates that in addition to the characteristic of excellent wear tolerance it’s also essential to identify those cultivars which can perform in combined shade and wear. It is important to consider
that a ‘highly rated’ cultivar for wear in the open field may not necessarily perform in a combined shade and wear situation, while a ‘lower rated’ open field cultivar may offer superior performance in combined shade and wear situations.
The trial also highlighted that cultivars which are more susceptible to leaf spot are the ones with poorer performance in this trial. There were also seasonal variations, with some cultivars performing better in the winter months and others
