| Abstract/Contents: | "The effects of cutting height (20 and 44 mm), frequency (once every 2 weeks April-September inclusive and twice a year) and seed rate (250 and 20 kg ha-1) on the water use and herbage yield of perennial ryegrass swards, for 3 years after sowing, were compared. Frequent cutting and a low cutting height reduced water use in the first year only. In later years infrequent cutting led to higher yields and higher water-use efficiencies, but did not affect total water use or the shape of the soil water profile. Seed rate influenced sward composition and the pattern of water use, but not total water use. The swards from the low seed rate had a lower stubble biomass and tiller density, and extracted relatively more water at depths of 75 and 85 cm and less at depths of 15 and 35 cm, than the swards derived from the high seed rate. The ratio of actual:potenital evapotranspiration was reduced as the soil water deficit increased and was lowest in the summer after a dry spring. Cutting height and frequency during summer were shown not to be effective methods of either conserving water or manipulating the effective rooting depth of an established sward." |
