The scarcity of water in the Mediterranean area has frequently led to the use of saline water for irrigation. Container grown ornamental production has relatively high rates of water and nutrient loss from fertigation. A better understanding of water and nutrient use efficiency with water that has elevated levels of saline could reduce runoff water and its environmental impact. Fern leaf lavender (Lavandula multifida) plants were grown for 8 weeks in plastic containers with a sphagnum peatmoss and perlite substrate (80:20 by volume) to evaluate the effect of saline water [2.0 (T1 or control), 4.5 (T2), or 7.5 (T3) dS m] on water and nutrient uptake efficiency. Leachate was collected to determine runoff volume and composition which included nitrate-nitrogen (NO3 -N), phosphate-phosphorus (PO4 -P), and potassium (K) concentration. Plant dryweight (DW) and nutrient content were determined in plants at the beginning and at the end of the experiment to establish the nutrient balance. Increasing salinity levels of irrigation water did not significantly reduce either the plant DW or the water use efficiency (WUE). Based on nutrient balance, the increasing salinity (2.0 to 7.5 dS m) affected the plant nutrient uptake efficiency, which decreased 28% for N, increased 26% for P from the lowest to highest sodium chloride levels; whereas K did not show a clear trend. Nutrient runoff increased (28% N, 9% P, and 27% K) to the environment from the lowest to highest sodium chloride levels.
