Organic amendments effects on nutrient uptake, secondary metabolites, and antioxidant properties of melastoma malabathricum l.

Amelioration of soil acidity can boost soil fertility, hence increasing nutrient uptake, secondary metabolite, and its antioxidant potential. In the present study, the effectiveness of food waste compost and palm kernel biochar was assessed as soil amendments for Melastoma malabathricum L. grown in...

In the present study, the effectiveness of food waste compost and palm kernel biochar was assessed as soil amendments for Melastoma malabathricum L. grown in acidic soil conditions. A six-month greenhouse study was conducted using completely randomized design (CRD) with three treatment groups, including control plants (T1), plants amended with palm kernel biochar (T2), and plants amended with food waste compost (T3). Data analysis revealed that Melastoma malabathricum L. amended with T3 recorded the highest total chlorophyll content (433.678 +/- 13.224 mu g g(-1) DW), followed by T2 and T1. The increase in chlorophyll content was contributed by the increase in soil pH. This was shown by the positive significant correlations between soil pH and chlorophyll a (r(2) = 0.96; p <= 0.01) and chlorophyll b (r(2) = 0.778; p <= 0.01). In addition, the same treatment exhibited the highest total anthocyanin content (leaves; 36.1 x 10(-2) +/- 0.034 mg/g DW and root extract; 8.9 x 10(-2) +/- 0.020 mg/g DW), total phenolic content (stem extract; 4930.956 +/- 16.025 mg GAE/g DE), and total flavonoid content (stem extract; 209.984 +/- 0.572 mg QE/g DE). Moreover, this study also found that the highest antioxidant potential against 2,2-Diphenyl-1-picrylhydrazyl (DPPH) and 2,2-Azinobis (3-ethylbenzothiazoline-6-sulfonic acid (ABTS) radicals was exhibited by samples supplemented with food waste compost (T3), followed by palm kernel biochar (T2). This indicates that the soil amendments have the capacity to enhance the secondary metabolites that protect plants, therefore ameliorating Melastoma malabathricum L.'s response towards acidic stress, and resulting in better antioxidant properties. Furthermore, this study also recorded better nutrient uptake in T3. With the significantly higher levels of macronutrient in the soil, the food waste compost could enhance the nutrient properties, secondary metabolites, and antioxidant capacity of Melastoma malabathricum L. grown in acidic soil conditions.
