Abstract
Taka (Tacca leontopetaloides) is a herb plant that grow in sandy soil structure of coastal area. The tuber of Taka has quite high nutrient content mainly carbohydrate. Nowadays, the utilization of Taka tuber is limited due to low its availability. This research aimed to obtain the fertilizer method to enhance the production and nutrient content of Taka tuber. The research was conducted in the field using Randomized Block Design with 6 treatments i.e. without any fertilizer as a control, manure only, manure combined with inorganik fertilizer (NPK) 50%, manure combined with NPK 100%, manure combined with biofertilizer and NPK 50%, and manure combined with biofertilizer and NPK 100%. All those treatments were replicated 5 times. The result showed that the highest production of Taka tuber was in plant treated with manure combined with biofertilizer and NPK 50%. However, biofertilizer could not enhance the nutrient content of Taka tuber.
