Description

Perennial ryegrass-white clover (Lolium perenne-Trlfollium repens) swards of 3 clover cultivars were studied at a lowland (30 m) and upland (340 m) site in mid Wales over 3 years (1989-91). Lamb production from small-leaved Aberystwyth S 184 at 1021 kg/ha was 25% and 1191, more than from small-leaved Ac3351 and medium-leaved Grasslands Huia respectively. The relative lamb output from Huia was poorer at the upland location. Clover production, survival and morphology under a number of cutting heights and frequencies were different from those in the continuously stocked pastures. Cutting every 10 days at 2-3 cm resulted in poor clover and ryegrass persistence. Harvesting every 21 days or 42 days at 3-4 cm underestimated the productivity of the small­leaved cuttivars, especially that of the more prostrate Ac 3351. The results highlight the problems associated with small-plot cutting evaluation of white clover cultivars.

Relative Productivity and Persistense of White Clover Cultivars Under Cutting or Continuous Stocking by Sheep
