An investigation was carried out to study the effects of abiotic stress factors on growth, physiology and total withanolide production in Withania somnifera (L.) Dunal. The abiotic stresses were provided in the form of three levels of light stress (25%,50% and 75% shade) and three levels of water stress (25%,50% and 75% FC) along with control under optimum conditions. Withanolide production was significantly affected by various stress factors. Maimum values for plant height (57.75cm), length of tap root (28.00cm) total dry matter production (28.08g/plant) and specific leaf area(93.40 cm2/g)were recorded in plants grown under 75% shade. The secondary metabolite withanolide was found to be significantly affect by abiotic stress factors and was also recorded maximum (64.75mg/g) in plants grown under 75% shade.
