The impact of different nitrogen sources and levels on andrographolide accumulation and partitioning was investigated in Andrographis paniculata (Burm. F.) Wall. ex. Nees. Nitrogen application @ 40 kg/ha resulted in maximum active principle (Andrographolide) accumulation in roots and above ground plant parts. Significantly maximum andrographolide yield was noted with 40 kg N/ha in the form of castor cake (67.40 kg/ha) and the minimum in control (31.50 kg/ha), while biomass yield was maximum with 40 kg N/ha supplied as urea (2185.19 kg/ha) and minimum in control (1601.85 kg/ha).
