Poa pratensis L. as a turfgrass in Britain1

Abstract

Eight cultivars of Poa pratensis L. were examined under conditions of establishment and low management typically encountered on school and local-authority playing fields in Britain. Poa pratensis L. was grown alongside and in mixtures with turfgrasses normally used in Britain on sports fields where the winter games of soccer and rugby are played. The time of emergence was similar for all turfgrasses examined. Lolium perenne L. ‘S.23’ reached a height of 5 cm 14 days before any of the examined cultivars of Poa pratensis L., indicating a much more rapid rate of establishment. When sown in a 6:1 seed number ratio with Lolium perenne L. or in a 2:1 seed number ratio with Phleum pratense L. and at an overall seeding rate of 24 g/m2, Poa pratensis L. failed to establish.

Two severe infections of rust affected only Poa pratensis L. The most resistant cultivar was ‘Baron.’ ‘Nugget’ and ‘Arista’ were virtually eliminated by the infections. ‘Fylking,’ although infected, recovered well.

Rugby was played over the trial plots throughout a winter period and there was no evidence that Poa pratensis L. cultivars tolerated wear less well than cultivars of the other turfgrass species examined.

The evidence produced suggests that the main obstacles to the success of Poa pratensis L. as a turfgrass in Britain are its slow rate of establishment and disease susceptibility, rather than intolerance of wear.
