Applying a nutrient solution with high EC
has been a common commercial practice to improve fruit quality of cherry
tomato. However, rapid yield reduction associated with continuous
high salinity stress to the plants is considered as problematic. The
objective of this experiment is to determine whether manipulating the drip
EC can sustain quality attributes (Brix %, acidity, fruit firmness), while
maintaining yield especially later in the crop season. Two selected
cultivars are examined and grown hydroponically with three separate EC
treatments. The EC treatments consist of a low EC, high EC and a
combination of high EC or low EC. Future trials include manipulation of EC
according to plant responses and greenhouse environments to provide a more
precise and effective application of EC treatment.
