Growth and Yield of Bujang Marantau Rice Variety (Oryza sativa L.) on Peat Land Due to Application of Fly Ash
Abstract
Rice production in Indonesia has declined in recent years, primarily due to the conversion of agricultural land into residential areas. Utilizing peatlands as agricultural land presents a viable alternative to address this issue. This study aimed to evaluate the growth and yield of the Bujang Marantau variety of rice in response to various doses of fly ash ameliorant applied to peatlands. The research employed a Randomized Block Design, which included four treatments with different fly ash doses: 0 tons/ha, 5 tons/ha, 10 tons/ha, and 15 tons/ha. Each treatment was replicated three times. Data were analyzed using the F-test at a significance level of 5%, followed by the DNMRT test at the same level if significant effects were observed. The results indicated that the application of fly ash significantly influenced the leaf area index; however, it did not have a notable impact on several growth and yield parameters, including plant height, root length, root volume, total number of tillers, number of productive tillers, Percentage of filled grains per panicle, weight of 1,000 grains, and yield per hectare. Fly ash should be applied at a dosage of 5-10 tons per hectare for peatland cultivation of the Bujang Marantau rice variety, as it is generally effective in enhancing plant growth and yield.
