Abstract:
Tomato is the most important horticultural crop in the world. The yields for this crop are highest in
Southeastern Spain. In this work we studied a commercial variety of tomato, with different soilless
culture systems (deep flow technique, nutrient film technique, and the perlite substrate) and three
levels of salinity (2.2, 6.3, and 10.2 dS·m−1) typical of Southeastern Spain. The irrigation management
was carried out for optimizing the water use efficiency. Alterations in the water status of the plants,
Cl− and Na+ toxicity, and nutritional imbalances altered the vegetative growth and physiology of
the plants. The marketable yield was affected by both soilless culture system and salinity. Regarding
the soilles culture system, yield decreased in the order: deep flow technique > perlite > nutrient film
technique. The salinity treatments improved the fruits quality by increasing the total soluble solids and
titratable acidity. Plants cultivated with the nutrient film technique had the highest concentrations of
Cl− and Na+ and the highest Na+/K+ ratio. The concentrations of Cl− and Na+ in the plants were not
related directly to the yield loss. Therefore, the influence of the toxicity, osmotic effect, and nutritional
imbalance seems to have been responsible for the yield loss.
