Effect of Sowing Dateson Morphological Characteristics, Root Yield and Chemical Composition of the Root ofWithania Somnifera Grown in the Semi-Arid Regions of Andhra Pradesh, India

The present study was undertaken to study the effect of sowing date on morphology, yield and chemical composition of root of Withania somniferagrown in the semi arid regions of Andhra Pradesh, India. The experiment was carried out in the research farm of Central Institute ofand Aromatic Plants (CSIR-CIMAP) , Research Centre, Hyderabad, India during 2009-2011. The experimental material included two morphologically differen t ashwagandha cultivars i.e. Poshita [variety developed by CIMAP] and Nagore [local variety g
