| Summary: | Background and Objective: Gynura procumbens (Lour.) Merr., is a herbaceous plant of the Asteraceae family and the phytochemical
contents of this plant play a significant role in health benefits. Optimizing fertilizer application is among the key strategies in enhancing
the growth and phytochemical content of Gynura procumbens. Thus, the experiment was conducted to evaluate the effects of
chicken manure rates on growth, physiological characteristics and phytochemical contents of leaves of Gynura procumbens.
Materials and Methods: The research was structured using a Randomized Complete Block Design (RCBD) with the inclusion of four
replicates. The experiment consisted of five fertilizer rates of processed chicken manure, ranging from 0, 100, 200, 300 and 400 kg haG1
and applied in two split applications. The study was conducted from January until March, 2017. Results: The highest plant growth and
total dry matter were recorded at application of 300 to 400 kg haG1 fertilizer. As the fertilizer rate increased, there was a noticeable decline
in total phenolic content, total flavonoid content, antioxidant activity and chemical markers. A significant interaction between the fertilizer
rate and leaf maturity on kaempferol-3-glucoside and kaempferol-3-rutinoside content was also observed. Young leaf was found to
contain higher chemical markers. Conclusion: Considering the plant growth and phytochemical contents, the application of 300 kg haG1
was recommended as the optimum fertilizer rate for G. procumbens. |
