Hydroponic tomato cultivation using organic fertilizer from bonito fish-based soluble
Organic fertilizer used in hydroponic systems often causes a phytotoxic phenomenon that could inhibit the plant growth.
However, processing the organic material by using a multiple parallel mineralization (MPM) method could efficiently allow the decomposition of organic materials without the accumulation of phytotoxins and dissolved oxygen deficiency in a hydroponic culture system.
Organic material from dried bonito production waste could be the nitrogen source for organic fertilizer generation.
In this research, the effect of organic fertilizer from bonito fish-based soluble and conventional chemical nutrient solution in the yield and quality of tomato plants in the greenhouse were compared.
There were no significant differences in the total yield plant‑1, total dry matter (TDM), sugar content, and fruit quality (GABA and lycopene) between organic and chemical treatment, except for citric acid in tomato fruits.
Where the total yield plant‑1 produced by organic fertilizer was 96.2% from conventional chemical fertilizer production.
Therefore, with the better environmental impact, organic hydroponic production by using bonito fish-based soluble can compete with conventional fertilizer production.
