Other claims from this paper (15)

Intervention effect Fungicides did not affect total annual dry matter yields at any of the three sites.
Intervention effect Some fungicides slightly affected yield at some individual harvests.
Observation Slight crown rust occurred on perennial ryegrass at Hurley in autumn 1972.
Intervention effect Crown rust on perennial ryegrass was well controlled by oxycarboxin.
Intervention effect Crown rust on perennial ryegrass was slightly controlled by benomyl.
Intervention effect Yields of perennial ryegrass were not increased although crown rust was controlled by oxycarboxin and slightly by benomyl.
Observation Drechslera spp. seemed slightly more common where the rust was controlled.
Intervention effect At Hurley the ley yielded more with 400 kg N/ha than with 100 kg N/ha.
Intervention effect The extra nitrogen fertilizer did not damage the sward at Hurley.
Intervention effect The extra nitrogen fertilizer did not affect the amount of disease at Hurley.
Intervention effect At Aberystwyth the leys were not damaged by 400 kg N/ha.
Observation Yields at Aberystwyth were large.
Intervention effect On old pasture at Rothamsted, extra NK fertilizer never increased the yield of herbage.
Intervention effect On old pasture at Rothamsted, extra NK fertilizer once slightly decreased the yield of herbage.
Mechanism The authors suggest the yield decrease may have been because patches of sward failed to regrow where more fertilizer was applied.

Other claims from this paper (16)

Observation Lucerne yields were smallest in late summer and autumn.
Observation Lucerne yields were largest in late spring and early summer.
Intervention effect Treatments generally had little effect on the seasonal growth rhythm of lucerne.
Intervention effect Frequent cutting nearly always decreased lucerne yields compared with standard cutting.
Intervention effect The relative decrease in yield from frequent cutting was greater with wide spacing than with close spacing.
Intervention effect Wide-spaced lucerne plants yielded more per plant than close-spaced plants, except in late summer.
Intervention effect Wide-spaced lucerne plants yielded less per unit area than close-spaced plants, except in late summer.
Association Sowing time influenced lucerne yield only until the middle of the first summer.
Observation Number of stems per plant was smallest in autumn and winter.
Observation Number of stems per plant was largest in spring and early summer.
Observation Mean weight of each stem was smallest in autumn and winter.
Observation Mean weight of each stem was largest in spring and early summer.
Intervention effect Number of stems per plant was largest at wide spacing and generally increased throughout the experiment, compared with close spacing.
Observation At close spacing, maximum stem numbers were attained in the establishment year.
Observation Weight per stem showed greater seasonal variation than stem numbers.
Mechanism Low winter yields and low yields with frequent cutting could be largely attributed to small stem weights.
