Summary
This field trial investigated the application of deep sea water as a nutrient supplement in multi-truss tomato cultivation using nutrient film technique, testing different treatment durations. Deep sea water treatment enhanced fruit enlargement during rapid growth phases and improved fruit quality characteristics (higher soluble solids, acidity, and dry matter) and yield compared to control cultivation, though some beneficial effects declined across successive trusses.
Regional applicability
This study was conducted in Indonesia and reflects tropical horticultural conditions. The findings may have limited direct applicability to United Kingdom protected cropping systems, which operate under different climate, photoperiod, and growing season constraints; however, the mechanistic findings on deep sea water micronutrient supplementation could inform nutrient film technique optimisation in UK glasshouse tomato production if localised trials were conducted.
Key measures
soluble solids content, acidity, dry matter content, cuticle thickness and resistance, fruit weight, number of fruits, organoleptic quality
Outcomes reported
The study measured effects of deep sea water (DSW) treatment on fruit development, yield, and organoleptic quality across multiple truss tomato cultivation. Key metrics included soluble solids content, acidity, dry matter content, cuticle thickness, and fruit yield (weight and number).
