Compost and Synthetic Fertilizer Affect Vegetative Growth and Antioxidants Activities of Moringa oleifera

Abstract

Moringa oleifera Lam, a highly valuable food commodity that has wonderful range of medicinal uses and possessing high nutritional value. A pot study was conducted to evaluate the combined effects of compost and N:P:K (21:17:17) on growth and antioxidative activities of moringa under greenhouse conditions. Compost and N:P:K fertilizers were applied separately and in combination including control (no fertilizer), 100 g Compost, 2 g NPK, 2 g+100 g (NPK+ Compost), 4 g +200 g (NPK+ Compost) and 6 g+300 g (NPK+ Compost). It was found that when moringa plants were fertilized with 2 g of NPK, it produced maximum plant height (44.79 cm), stem girth (6.33 mm), leaf score (342.40), number of branches (16.07) and crude protein (9.76 mg/g dry weight) contents. Carbohydrate, phenolics, flavonoids (291.25, 16.61, 2.019 mg/g dry weight) respectively were recorded in highest quantity in 100 g compost treated plant. The compost (100 g) treated plants also displayed promising antioxidant activities in terms of the IC50 and ICo.5 values. Therefore, it is concluded that the compost and NPK treatments can effectively improve the vegetative growth, biochemical, phytochemical and antioxidant activities of moringa plant.

Drumstick (Moringa oleifera) variation in biomass and total flavonoid content in Indonesia

“…Turkoglu et al (2007) also stated that the low IC50 value in the antioxidant activity test reflects the high antioxidant activity in a sample. The IC50 value of the leaf extract of all drumstick accessions in this experiment was much lower than the IC50 value of drumstick leaf extract reported by Anigboro et al (2019) of 3190 µg mL -1 and Sarwar et al (2017) amounted to 831.67 µg mL -1 to 1653 µg mL -1 . It means that the antioxidant activity of drumstick leaf extracts of all accessions used in this experiment was quite high, especially Sumatra accessions.…”

Respuesta al bocashi y a la lombricomposta de Moringa oleifera Lam. después de la poda

“…Por lo que la lombricomposta resultó ser el abono con mayor potencial para la producción de follaje. Mientras que Sarwar et al (2017) establecieron que dosis menores al 1% de N-P-K pueden incrementar tallos y follaje de moringa en 50% o más en un suelo franco sin fertilización.…”

Combined effects of provenance and NPK-fertilizer on nursery performance of kelor (Moringa oleifera) seedlings

“…NPK fertilization had a significant effect on diameter increasing [18,14]. The NPK fertilizer provided a quick supply of macronutrients (N, P, K) to the plants as compared to compost, from which the slow release of nutrients took place [19]. However, the statistical analysis also showed that there was a significant effect on the interaction of provenance and NPK fertilization.…”
