Ameliorants formulation to increase rice yield in wetlands in Sijunjung District West Sumatera. The average yield of lowland rice in West Sumatra is still low due to low land fertility in the area of rice production centers. Low soil quality is characterized by low nutrient content, low organic matter, and high soil acidity. Improvement of soil quality can be done by managing soil enhancer such as providing organic materials, liming, zeolite applications, and balanced fertilization concepts. The study was conducted from June to October 2015 in Sei Langsek Village, Sijunjung District, West Sumatera. The experiments were arranged in a Two-Factor Randomized Block Design with 4 replications. As the first factor are three formulations of soil ameliorants, namely: 1) F1 (25% cow manure, 50% harzburgite, 25% zeolite, 0% dolomite); 2) F2 (50% cow manure, 25% harzburgite, 15% zeolite, 10% dolomite); 3) F3 (75% cow manure, 15% harzburgite, 5% zeolite, 5% dolomite); F4 (100% cow manure). As the second factor is the dosage of soil ameliorant, namely: 2.5; 5.0; 7.5; and 10 t/ha. Without soil ameliorant was used as a control, so the combination of treatment amounted to 17 treatments. The results showed that the highest yield (6,160 kg GKG/ha) was obtained at F3 treatment with a dose of 5 t/ha followed by F2 treatment with a dose of 2.5 t/ha (5,740 kg GKG/ha). Based on the regression analysis, a more efficient soil ameliorant formulation for low productivity paddy fields in Sijunjung district was F2 with a maximum dose of 4,391 kg/ha.
