Abstract

Silicon has been used in several ways to improve plant growth and development; however, there are few experimental results, especially for tropical grasses. Thus, the objective of this work was to evaluate the effects of applying calcium and magnesium silicate on the growth, structure, and herbage mass of Mombasa grass. A completely randomized design was used in a 3 x 3 factorial arrangement with 4 replications and 2 duplicates for replications. The experimental treatments corresponded to two doses of silicon (1,000 and 2,000 kg/ha) and control (0 kg/ha) over 3 growth cycles. The variables evaluated were plant height, number of tillers, specific leaf area, herbage mass, leaf mass, stem mass, the mass of dead material, and root mass. The application of silicate was not able to modify the variables studied. Considering the soil studied, the application of silicate is not recommended to increase the productivity of Mombasa grass, but similar longer-term studies are needed on soils with low Ca and Mg levels.
硅酸钙镁在蒙巴萨草的生产
硅已经在许多方面被用于改善植物的生长和发育;然而,实验结果很少,特别是对热带草。因此,本研究旨在评价施用硅酸钙和硅酸镁对蒙巴萨草生长、结构和牧草质量的影响。采用完全随机设计,3 × 3阶乘排列,4个重复,2个重复。试验处理为两个剂量的硅(1,000和2,000 kg/ha)和对照(0 kg/ha),超过3个生长周期。评估的变量为株高、分蘖数、比叶面积、牧草质量、叶质量、茎质量、枯死物质质量和根质量。硅酸盐的应用不能改变所研究的变量。考虑到所研究的土壤,不建议施用硅酸盐来提高蒙巴萨草的生产力,但需要在低钙和低镁土壤上进行类似的长期研究。
