Plot Experiment

1. A small-scale plot experiment was conducted at the Hannah Institute for the 3-year period 1963–65, to study the comparative effect of applications of various mixtures of dung and urine (slurry treatments) on the yield and quality of an established S23 ryegrass and S100 white clover sward.

SUMMARYThe yield and quality of herbage produced by six grasses (perennial ryegrass, cocksfoot, timothy, rough-stalked meadow grass, tall fescue and Italian ryegrass) were examined both without irrigation and under two irrigation regimes. Water was applied according to the potential soil water deficit (potential SWD): the soil was either partially returned to field capacity (FC) after each cut or fully returned to FC whenever the potential SWD reached 25 mm. The swards were cut either at 3 (C3) or 6 (C6) week intervals over a 2 year period.Partial irrigation increased yields by 12–14% in the first year and by 36–58% in the second. Full irrigation produced little more growth than partial irrigation in the first year (maximum SWD, 188 mm) but increased yield by 78–93% in the second, very dry, year (maximum SWD, 311 mm). Under treatment C3 response per unit of water applied was similar with both partial and full irrigation, but under C6 the response was greater with partial (2·86 kg D.M./m3) than with full irrigation (1·79 kg D.M./m3).There were marked differences between the species in their ability to grow under drought conditions in the second year of the experiment. Without irrigation, roughstalked meadow grass and Italian ryegrass did not survive the drought. The performance of tall fescue was markedly superior to both perennial ryegrass and cocksfoot in these conditions. Of the surviving grasses timothy made least growth.

The Difference

SUMMARYYields and quality of herbage from a cocksfoot/white clover sward were compared over a 3-year period when cut repeatedly with a reeiprocating-blade mower to either 1 in or 2½ in from ground level or with a cylinder lawnmower to 1 in from ground level. The comparisons were made under two frequencies of cutting, namely five times per season at the ‘grazing’ stage, or three times at the ‘silage’ stage.Cutting to 1 in from ground level with the reciprocating-blade mower gave a greater total yield of dry matter and crude protein than did cutting to 2½ in with the same mower in the first year, when the average dry-matter yield difference was 10·7 %, but no significant differences were recorded in subsequent years. It is suggested that the difference noted in the first year was due mainly to the harvesting at the first cut in the season of the layer of herbage between 1 and 2½ in from ground level, and not to any differential effects of the treatments on stem and leaf development of the cocksfoot.Cutting to 1 in from ground level with the lawnmower gave smaller dry-matter yields than did cutting to 1 in with the reciprocating-blade mower at both stages of growth in the first year, but a slightly greater yield at the ‘grazing’ stage in the third year. The type of mower used affected the botanical composition of the sward.
