Impact of Organic and Inorganic Fertilizers Application on the Phytochemical and Antioxidant Activity of Kacip Fatimah (Labisia pumila Benth)

Abstract

Abstract:A study was conducted to compare secondary metabolites and antioxidant activity of Labisia pumila Benth (Kacip Fatimah) in response to two sources of fertilizer [i.e., organic (chicken dung; 10% N:10% P 2 O 5 :10% K 2 O) and inorganic fertilizer (NPK green; 15% N, 15% P 2 O 5 , 15% K 2 O)] under different N rates of 0, 90, 180 and 270 kg N/ha. The experiment was arranged in a randomized complete block design replicated three times. At the end of 15 weeks, it was observed that the application of organic fertilizer enhanced the production of total phenolics, flavonoids, ascorbic acid, saponin and gluthathione content in L. pumila, compared to the use of inorganic fertilizer. The nitrate content was also reduced under organic fertilization. The application of nitrogen at 90 kg N/ha improved the production of secondary metabolites in Labisia pumila. Higher rates in excess of 90 kg N/ha reduced the level of secondary metabolites and antioxidant activity of this herb. The DPPH and FRAP activity was also highest at 90 kg N/ha. The results indicated that the use of chicken dung can enhance the production of secondary metabolites and improve antioxidant activity of this herb.

Antioxidant content of Tomatoes (Lycopersicon esculentum cv MT1) treated by different type of Pesticide, Fertilizer and growth medium in Compost

“…Though other researchers and co-workers showed that chicken dung 17 and sludge 18 can resemble soil conditioner and able to improve the nutrient supply in the soil for sunflowers, our finding showed the compost was not able to contributed towards TPC, DPPH and FRAP analysis. Our findings were also in contrast with 12 which showed the usage of fertilizer could enhance the production of secondary metabolites and improve antioxidant activity (DPPH and FRAP) of Labisia pumila herb. This may be due to different species of plants, fertilizer and the origin of the compost applied in the growth of plant.…”

“…Whereas, fertilizer is used to support plant growth and yield. Application of organic manures along with chemical fertilizer was possible and reported by several researchers and co-workers 12,13 . While, application of EFB along with chemical, or organic or both chemical and organic fertilizer has not reported in tomato.…”

Influence of organic and mineral fertilizers on the antioxidants and total phenolic compounds level in tomato (Solanum lycopersicum) var. mongal F1

“…(Ibrahim et al, 2013). Furthermore, the use of organic manure increases soil fertility by improving its physical, chemical, and biological properties (Khalil et al, 2007).…”

Impact of different fertilizers on some phytochemical constituents and biological activities of Beta vulgaris L. leaves

“…Food and Agriculture Organization of the United Nations (FAO) developed a strategy named Integrated Plant Nutrition System (IPNS) to promote crop and soil productivity through the use of a balanced combination of chemical, organic and biofertilizers. Moreover, the consumers, nowadays, are greatly cocerned with the harmful effects of plant chemical fertilizers on their health, as well as polluting the environment [4]. The impact of different fertilizers on production of secondary metabolites in plants is not widely studied, yet some authors suggested that organic fertilization can enhance the production of these metabolites versus inorganic fertilizers [4][5][6][7].…”

As no studies could be traced concerning the efficacy of various fertilizers on beet greens metabolites and in a continuation to our previous study regarding evaluation of the effect of different fertilizers on growth and bioconstituents of red beet bulbs [8], thus, the present work aimed at investigating the impact of fertilizers on some growth parameters, phytochemical constituents and biological activities of the beet leaves.…”
