Abstract

This study aims to evaluate the effect of various doses of coal fly ash ameliorant on the growth and yield of several local rice varieties of West Sumatra on peatlands. Peatlands that have low fertility, high acidity, and limited nutrient content are the main challenges in rice cultivation. Fly ash, which is waste from coal combustion, is used as an ameliorant because it contains silica and other minerals that can improve soil structure, increase pH, and provide nutrients. The four rice genotypes used were Bujang Merantau, Kuriak Supayang, Redek, and PB 42, with four doses of fly ash (0, 5, 10, and 15 tons/ha). The study was conducted using a split-plot design, with the results showing that fly ash increased soil pH from 3.83 to 6.65, improved water content, and increased C-organic content. The optimal dose of fly ash was 10 tons/ha, which supported plant height. 2. Genotypes Redek and Bujang Merantau showed the best results in the number of filled grains per panicle and yield weight per hectare at this dose. The provision of higher doses still needs to be evaluated further. This study concluded that the combination of varieties and the right dose of ameliorant has the potential to increase local rice productivity on peatlands sustainably.
