Variouse?orts have been made to increase the productivity of Indonesian peatlands, one of which is by adding salted ?sh waste and cow manure. This research was carried out on a plastic house scale from October 2017 to January 15, 2018, in Pelalawan District, Pelalawan Regency, Riau. This research was carried out on a plastic house scale from October 2017 to January 15, 2018, in Pelalawan District, Pelalawan Regency, Riau. This research was arranged in a Completely Randomized Design (CRD), consisting of eight treatments, namely L0 = Control, L1 = 1.5 ton.ha-1of ?sh waste, L2 = 2.25 ton.ha-1of ?sh waste, L3 = 7 ton.ha-1of cow manure, L4 = 15 ton.ha-1of cow manure, L5 = 1.5 ton.ha-1of fish waste + 7 ton.ha-1of cow manure, L6 = 1.5 ton.ha-1of fish waste + 15 ton.ha-1of cow manure, L7 = 2. 25 ton.ha-1of ?sh waste + 7 ton.ha-1of cow manure, and L8 = 2.25 ton.ha-1of ?sh waste + 15 ton.ha-1of cow manure. The results showed that the application of cow manure and salted ?sh waste could increase soil pH, total NPK, and NPK uptake. The application of 2.25 ton.ha-1of ?sh waste and 15 ton.ha-1of cow manure resulted the best results in soil pH, total NPK, and NPK uptake, therefore it is recommended for the cultivation of lowland rice on peat soil. |
