| dc.description.abstract | Application of ameliorant on peat soil is important to do for improvement the soil quality for supporting plant growth. The aims of this research is to compare paddy’s response on peat soil with applying 700℃ burned dolomite-trass mixture with trass, steel slag, dolomite and its combinations. This research use randomized complete design that included of control, 50% NPK, 5% steel slag, 5% trass, dolomite (2.5%, 1.9%, and 1.3%), 5% 700℃ burned dolomite/trass (0.5:1, 0.75:1, and 1:1), and 5% combination of steel slag and dolomite-trass 1:1 (25:75, 50:50, and 75:25). Each treatments is perfomed in three replications. The result showed that application the combination of steel slag and 700℃ burned dolomite-trass 1:1 (25:75) was better to increase soil pH, plant height, tiller, and dry weight of plant than the other treatments. Beside that, application the combination of steel slag and 700℃ burned dolomite-trass 1:1 (25:75) is also better to increase N, P, K, Ca, Mg, Fe, Cu, and Zn uptake and also to increase the RAE of N, P, and K than the others. | en |
