abstract

• The effluent from aquaculture activities contains essential elements that can be used in agriculture. In this study, the effluent from tilapia (Oreochromis niloticus) production was used to fertilize garlic with four nitrophosphoric treatments: 1) no fertilization, 2) 40–20, 3) 80–40, and 4) 160–80 (kg·ha21 of N and P2O5, respectively). Treatment 3 resulted in the highest yield and better plant nitrogen levels. The effluent from tilapia aquaculture is a significant source of nitrogen and phosphorus. Hence, it is crucial to calculate the fertilization precisely based on the contributions of the soil and the effluent. However, the effluent did not provide significant levels of K, Mg, Fe, Cu, Mn, and Zn, which were adequately provided by the soil. The effluent did contain elevated levels of Ca and S due to the original water contents.
