Fish protein powder is a popular organic fertilizer today and is widely available and safe. Dora Agritech's enzymatic hydrolysis technology manufactures deep-sea fish protein into fish protein powder, which is easy to apply and post-formulate.
The Dora trial team applied fish protein to blueberries and measured the average fruit weight, soluble solids content, sugar-acid ratio, anthocyanins, flavonoids and vitamin C content after applying fish protein at different dilution ratios.
| Treatment Group | Average Fruit Weight (g) | Soluble Solid (%) | Total Sugar (%) | Total Acid (%) | Sugar/Acid |
| 300 Times Dilution of Fish Protein Powder | 2.3 | 13.3 | 11.4 | 0.7 | 16.2 |
| 500 Times Dilution of Fish Protein Powder | 2.4 | 15.8 | 12.1 | 0.5 | 17.2 |
| 1000 Times Dilution of Fish Protein Powder | 2.6 | 14.6 | 11.6 | 0.5 | 23.2 |
| Control Group | 1.8 | 12.3 | 10.3 | 0.8 | 12.8 |
Trial result shows the application of fish protein fertilizer can increase blueberry fruit size, soluble solids content and sweetness. Reduce acidity and increase sugar-acid ratio. In terms of vitamin C, flavonoids, and anthocyanin content, the combination of other biostimulants is needed to obtain higher quality.
The recommended dosage of Dora Fish protein powder is 800-1000 time dilution, with irrigation or foliar spray.
