| description | Comparative Effects of Chromolaena odorata L. King R.M. & H.E. Rob Ashes and a Soluble Mineral Fertilizer (NPK 15 15 15) on the Growth and Yield of Guinea Sorrel (Hibiscus sabdariffa L.). The low levels of nutrients observed in the lateritic soils of Gabon are a concern. A trial conducted in vegetation pots was laid out in a Fisher randomized complete block design with 20 treatments and 3 replicates. The experiment aimed at comparing the growth and yield of Hibiscus sabdariffa L. under different fertilization modalities: a water soluble mineral fertilizer (NPK 15-15-15) added at four doses (0-0-0; 16-7-13; 19-8-16; 23-10-19 mg.kg-1 soil); Chromolaena odorata ashes at 0; 500; 667; 834; 1000 mg.kg-1 soil; and comparing the interactions between ash doses (C) and NPK doses (M). The C. odorata ash supply increased significantly the diameter of the stems, the height of the stems and the leaf area up to a dose of 667 mg.kg-1 soil. Among the compared doses, the one of 23-10-19 mg.kg-1 soil (M3) induced the highest effect on the plant growth parameters. The highest growth (167±68 g. fresh vegetal matter per pot) was obtained with the combination of 667 mg.kg-1 ashes at and 19-8-16 mg.kg-1 NPK (C2M2). |
