An experiment was conducted to study the effect of nitrogen and farm yard manure (FYM) on some physiological, biochemical parameters and quality of root of medicinal plant ashwagandha at pre-flowering and post-flowering stages. Significant differences in pigment content (chlorophyll and carotenoids) were observed in both pre and post-flowering stages. The total phenol and ortho-dihydric phenol content decreased with the application of nitrogen in pre-flowering stage, but increased with the application of nitrogen at post-flowering stage. The activity of polyphenol oxidase(PPO) showed an increasing trend with the application of nitrogen in pre-flowering stage and mixed trend in post-flowering stage. The highest grade of roots B, C and D were formed at all applied nitrogen levels. The quality of root based on the alkaloid content was found to be better at low nitrogen level (No and N 20 ) and FYM. However, the root yield was maximum 20 kg N ha -1
