e0“Tomato plants grown in rockwool at a salinity of 3 mS cm-1 were compared with those at 8 and 12 mS cm-1, where the higher salinities were achieved by addition of either major nutrients (N03-N, K and Ca) or NaCl”
e5“At both 8 and 12 mS cm-1, the acidity of the fruit juices was higher with added major nutrients than with NaCl, as was the total acid content per fruit”

Other claims from this paper (8)
- Intervention effect Increasing nutrient solution salinity progressively reduced tomato fruit yield (fresh weight) compared with 3 mS cm-1 in rockwool.
- Intervention effect Increasing nutrient solution salinity increased the proportion of tomato fruit graded as high quality (Class 1) compared with 3 mS cm-1.
- Intervention effect Salinity from added major nutrients and from NaCl gave similar tomato responses at 8 mS cm-1.
- Intervention effect At 12 mS cm-1, fruit number, dry weight per fruit and reducing sugar per fruit decreased compared with 3 mS cm-1.
- Intervention effect Added major nutrients adversely affected tomato vegetative growth at 12 mS cm-1 compared with NaCl.
- Intervention effect Added major nutrients reduced tomato fruit size, dry weight and sugar content at 12 mS cm-1 compared with NaCl.
- Intervention effect At 8 and 12 mS cm-1, fruit juice acidity was higher with added major nutrients than with NaCl.
- Mechanism Much of the increased fruit juice acidity under salinity is related to the reduced water content of the fruit rather than to the applied K level.
