highly significantP ≤ 0.01
Two-way ANOVA indicated that field capacity had a highly significant effect on all growth parameters (F = 15.91–32.7, P ≤ 0.01), while the treatment effect was significant for shoot fresh and dry weight as well as root fresh weight (F = 12.3–14.2, P ≤ 0.01), but not for root dry weight alone (F = 0.22, P = 0.804).
