Contamination of rice fields due to industrial activities had an impact on reduced soil fertility, heavy metal contamination from industrial waste, and reduced rice yields. To overcomed this problem, this could be done by applied NPK Bio-organomineral tablet fertilizer. NPK Bio-organomineral tablet fertilizer was a modification of fertilizer made from urea, guano, palm oil empty fruit bunch charcoal, zeolite, activated charcoal, and biologically enhanced compost, turning the fertilizer into a slow-release form. The experiment aimed to investigate the impact of applied NPK Bio organomineral tablet fertilizer on harvest index, wet weight, dry weight and fertilization efficiency in the waste contaminated soil. This experiment was conducted from September 2023 to January 2024 at the Greenhouse Experimental Garden of Ciparanje, Jatinangor, and the Soil Fertility and Plant Nutrition Laboratory, Universitas Padjadjaran. The experimental design used was a Randomized Block Design (RBD) consisted of eight treatments and four replications, included control, NPK Phonska 100% recommendation 250 kg/ha, and 125; 250; 375; 500; 625; 750 kg/ha of NPK Bio-organomineral tablet fertilizer. The results of the experiment indicated that NPK Bio-organomineral tablet fertilizer had an impact on harvest index, wet weight, dry weight and fertilization efficiency in the waste contaminated soil. The optimal dose of NPK Bio-organomineral tablet fertilizer was 375 kg/ha, showed the most significant improvement on harvest index, wet weight, dry weight and fertilization efficiency in the waste contaminated soil.
