Comparison of maize grain yield, and lodging rate in 2018 (a) and 2019 (b) at varied planting densities. LD, MD, and HD represent low, medium, and high planting densities, respectively. Bars denote the SE of the mean (n = 3). ns, not significant (P > 0.05), ** and *** indicate differences of grain yield significant at 0.01and 0.001levels, # and ### indicate differences of lodging rate significant at 0.01and 0.001levels.
