Growth rate study of mangrove using hydroponic installation system with mol nutrient at Central Processing Plant (CPP) Senoro Banggai Regency - Central Sulawesi

Abstract

Mangrove plantation is a biodiversity-environmental programs of JOB Tomori that had started since 2012. A total of 117.000 mangrove seedlings were successfully planted. Some innovations programs, more effective and beneficial, had been also carried out. One of it was 5 months experiment by growing mangrove in Hydroponic installation and polybag. Two parameters measured during the study 1) Seedling length and 2) number of seedling leaves. Results showed that additional length of seedling has vary in range with the highest length found on seedling that placed on the natural habitat area which reached 4.4 cm per week, while the highest number of leaves also found in the natural habitat area which reached until 10 leaves per month. Preliminary conclusion has been taken that mangrove that planting in hydroponic installation system using MOL (Local Microorganism - Natural Fertilizer) as nutrient can increase and speed up of seedling growth rate by 30 - 35% with a 100 % of survival rate.
