Different lowercase letters within a column indicate a significant difference under each treatment according to the least significant difference (LSD) (0.05). The error term is SE. ns, not significant at the 0.05 probability level; * and **, significant at the 0.05 and 0.01 probability levels, respectively. V, variety; T, treatment.
