Effects of Nitrogen Concentration on Growth, Yield and Phytochemical Content of Persicaria minor Cultivated Using Hydroponics System

Persicaria minor or locally known as kesum from the family Polygonaceae is a common herbal plant found in Malaysia. Hydroponic cultivation of using deep water culture (DWC) system can be an alternative option for growers increasing crop yields. The method which liquid fertiliser solution given directly to roots without any medium and flow. study’s main objective was determine effects nitrogen concentration on growth, yield phytochemical content cultivated hydroponic system. Plants were grown under one four regimes experiment conducted side netted rain shelter. treatments comprised 200 mg/L, 100 50 mg/L 0 concentrations. arranged Randomized Complete Block Design (RCBD) with 4 replications. selected randomly harvested eight weeks after planting. supplemented gave best growth performance biomass yield. They produced highest height (78 cm) fresh (174 g per plant). Meanwhile plants Quercetin-3-glucuronide (Q3G) (98.261 mg/mL) Quercitrin (61.367 compound compared other treatments. However, treated concentrations exhibited major nutrients deficiencies symptoms die 3 Hence, it concluded that hydroponics’ obtain higher compound, recommended.
