Comparison of the relative performance of perennial ryegrass varieties under upland and lowland conditions

Autor: E. L. Jones, D. A. Davies, T. E. H. Morgan

Publikováno v: Grass and Forage Science. 40:323-330

Productivity, seasonal growth and persistence of 10 perennial ryegrass (Lolium perenne L.) varieties were assessed al an upland (305 m) and lowland (30 m) site in mid-Wales. Averaged over 3 harvest years (1979–81), mean dry matter (DM) production a

Variation in spring temperatures, grass production and response to nitrogen over twenty years in the uplands

Autor: T. E. H. Morgan, D. A. Davies

Publikováno v: Grass and Forage Science. 43:159-166

Large between-year variation was observed in spring air and soil temperatures at Pant-y-dwr Hill Centre (305 m altitude) from 1967 to 1984 and at Bronydd Mawr Research Centre (330 m) from 1985 to 1986 in Powys. The mean date of attaining T-sum 200°C
