The yield parameters and cost economics of Withania somnifera were studied using Integrated Nutrient Management (INM) treatments. Withania somnifera is cultivated in around 10,780 ha with a production of 8429 tones in India. The annual demand of this herb increased from 7028 tones (2001-2002) to 9127 tones (2004-2005). The field experiment was conducted at the research farm of Department of Plant Physiology, College of Agriculture, Jabalpur during Kharif season of 2008-2009 (1^st year) and 2009-2010 (2^nd year), whereas the laboratory work was carried out in Quality Laboratory, College of Agriculture, Jabalpur. The soil of experimental field was sandy loam in texture with pH 7.5, EC 0.18 dsm^-1 having good drainage. Soil analysis revealed that available nitrogen was low (202.0 kg·ha^-1) whereas available phosphorus (16.25 kg·ha^-1) and potassium (236.0 kg·ha^-1) were in the medium range. The present paper shows how to determine the economics of varying INM treatments. Cultivation of W. somnifera in India is gaining popularity among farmers; however, due to poor soil fertility, and costly chemical fertilizers and pesticides its production is not economical or profitable.
