As shown in Table 3, at the end of the experiment, the
main effects, the interaction between water and nutrient
stress, was significant for leaf nitrogen and phosphorus
concentration (P < 0.05), but had no significant effect on
potassium concentration. Nitrogen, and phosphorus
concentration was lower in the nutrient and nutrient-water
stressed plants compared to the control plant. The
highest decrease in nitrogen, phosphorus, potassium
concentrations were 11.4 and 27.4%, respectively. But
potassium concentration was increased under stress
condition.
