SUMMARY In lettuce, results of three experiments showed that between 60 and 90 % of the variation in mature head weight and the date of head maturity could be accounted for by variation in the date of seedling emergence. Sowing pre‐germinated seeds using a fluid drill considerably reduced the time spread of both emergence and maturity compared with size‐graded natural seed sown conventionally.
