Total annual cumulative emergence (% ± SE) during the first year after burial of 30 rare arable plants from seeds sown in tilled and no-till plots, the tillage treatment; trials repeated for two consecutive seasons (S1, 2012/13; S2, 2013/14), the season treatment.

Soil disturbance was performed in early autumn in tilled plots. The 2nd through 4th columns represent significance for main effects and interactions on emergence analysed by GLM. Values followed by the letter a were significantly higher after analysing each season separately for tillage treatment due to significant interactions.
