  1. Within a column for earthworm casting treatments in each year and for cultivars in 2017, data with the same letters are not significantly different at the 0.05 probability level (LSD test).
  2. EC0 and EC1 represent absence (0 kg m−2) and presence of earthworm castings (17 kg m−2), respectively.
  3. Data are the means across three N rates in 2016.
