Abstract

Shallot is an important horticultural commodity which its productivity needs to be increased due to their imperative role in society. The solution offered in this research is the use of fish waste organic fertilizer that has high nutrient N, P, and K levels. This study aimed to evaluate the quality of organic fish waste fertilizer and its effect on shallot growth and yield. This research had been conducted in Bengkulu City from June to November 2025. Fish waste organic fertilizer was made using anaerobically fermented method using a local bioactivator made from bamboo shoots. A field study with a completely randomized design was conducted to test the effect of the application of different doses of organic fish waste fertilizer on shallot crop plants. The main results of this study proved that organic fish waste fertilizer had high nutrient contents of N, P, and K, totally 5.62%. this amount is exceeding the national minimum standard for organic fertilizer, which is 2.0%. The application of organic fish waste fertilizer increased the growth and yield of shallot. Shallot yields increased from 1,89 to 13.33 tons per hectare, respectively with doses of 0 and 15 tons per hectare of organic fish waste fertilizer. Local bioactivator and organic fish waste fertilizer have proven to be innovative solutions for increasing shallot productivity
