Intervention effect Early sowing increased winter barley yield by 79·8% in the first year.
Intervention effect Early sowing increased winter barley yield by 53·9% in the second year.
Intervention effect Late sowing approximately halved plant emergence.
Observation Late-sown plants had more tillers, more grains per ear and larger grain, but these did not compensate for thinner stands.
Observation Extra tillering and larger ears generally compensated for fewer plants in contemporaneous crops.
Intervention effect April nitrogen gave the best yield in early and late crops in 1975–6 and late crops in 1977–8.
Intervention effect March nitrogen gave the best yield in early-sown crops in the second year.
Intervention effect March nitrogen increased ear number in early-sown crops.
Intervention effect Nitrogen application date did not influence ear number in late-sown crops or grains per ear in any crop.
Observation Mildew developed on early and late crops throughout the mild 1975–6 winter.
Intervention effect Single autumn, winter or early spring tridemorph sprays increased yield by 6·3–7·6%.
Intervention effect Two sprays had an additive yield increase.
Intervention effect Late spring spray had no significant effect on yield.

Intervention effect The row-spacing impact on yield was greater at 48 or 50 cm than at 36 cm.
Intervention effect Rigid ryegrass competition reduced barley grain yield at two of four sites.
Association The weed competition effect on barley yield was the same at narrow and wide spacing at both locations.
Association At one location cultivar modified the weed competition impact.
Intervention effect Wide barley rows increased rigid ryegrass biomass production.
Intervention effect Wide barley rows increased rigid ryegrass tiller number.
