The time taken for 50% seeds to germinate (t½) was computed from germination profiles generated from triplicate plates with 100 seeds each sown on moist cotton containing distilled water (DW) or Arnon Hoagland media (M) with or without N as specified in the titles of the columns. The ranking was based on the t½ values obtained in medium with nitrate (first column), which corresponds well with other N treatments.
