MIXTURE: 100% perennial ryegrass
USAGE:
Renovation and/or construction of winter sports pitches
FEATURES & BENEFITS
RPR SPORT is a highly researched blend of four hard- wearing perennial ryegrasses for the renovation and construction of elite winter sports pitches.
Four years of dedicated wear trials at our research station Cropvale in Worcestershire, together with close analysis of BSPB Turfgrass Seed and the official French list as well as data from our breeding stations across the globe has delivered a blend focussed on four key traits for high performance pitches – wear tolerance, dark genetic colour, disease tolerance and recovery.
The wear trials at Cropvale are run annually in line with the football season and are assessed via an objective method called Digital Image Analysis (DIA). A camera box takes images of trial plots on a monthly basis and DIA enables the production of extremely accurate data on both wear tolerance and genetic colour for both cultivars and, critically, mixture formulations. Figure 1 summarises the process.
BSPB/STRI Turfgrass Seed 2021 data supports the Cropvale Research. Barcristalla and Barorlando are ranked #12 and #19, respectively, for mean performance under wear and #2 and #1 for autumn colour (in the top-50 varieties). Figure 2 illustrates this point. The two yellow dots are Barcristalla and Barorlando; both exhibit an excellent combination of colour and performance.
Barlibro is a Regenerating Perennial Ryegrass (RPR) that produces stolons as it establishes and grows. Figure 3 shows a Barlibro plant grown for a single seed at 15 months old. The stolons and new secondary branches of growth can be seen clearly. The lateral growth habit results in fast establishment between seeding lines and unparalleled capacity for recovery after and during wear.
