Abstract

An experiment was designed with Randomized Complete Block Designed to investigate the effects of organic and inorganic nitrogen fertilizer at 90 kg N/ha on growth and leaf gas exchange in two varieties of Labisia pumila at 15 weeks after transplanting (WAT). In this study total biomass and photosynthesis (A) were significantly (P?0.05) different among all factor. The results indicated that chicken manure enhanced the net photosynthetic rate (11.10 µmol/m²/s), stomatal conductance (0.40 mmol/m/s) and transpiration rate (5.30 mmol/m²/s) of L.pumila significantly after 31 weeks of planting. Chicken manure and Gobi indicated higher accumulation on total phenolic and total flavonoid compared to NPK green and control. Organic fertilizers (chicken manure and Gobi) were positively influenced the leaf gas exchange and growth of L.pumila as compared to the NPK green and control. This study proved that organic fertilizer can produce a quality of L. pumila compared to NPK green. Based on the principle of organic fertilizer which is slowly release from organic fertilizer will limit the nutrient availability for plant growth and allocate more carbon to produce secondary metabolites.
