Extract

1. An experiment was conducted in 1959 and 1960 on a rye-grass-white clover sward under a ventilated Dutch light structure to study the influence of the following treatments in all combinations. Cutting to within 1 in. or within 3 in. of ground level, cutting six times per year as for grazing or four times a year as for silage, applying water to restore the soil to field capacity (a) when the soil moisture tension at 1 ft. depth reached 10 cm. Hg, or (6) when the soil moisture tension at 1 ft. reached 50 cm, Hg, or (c) once only in the growing season. Observations were made on the effect of the treatments on the yield and seasonal distribution of herbage dry matter, the clover content, the crude-protein and crude-fibre content, and the root weights.
