  1. aBolded values indicate statistical significance at α = 0.10
  2. bRice canopy coverage is from the 2022 Lonoke and Pine Tree site-years only due to excessive weed pressure and software limitations at other site-years. Echinochloa crus-galli density, panicle counts, and seed production is from 5 site-years.
