Abstract
Ashwagandha (Withania somnifera L. Dunal) is a drought-hardy medicinal herb widely utilized in Ayurvedic and tonic medicine. Ashwagandha naturally grows in arid to semi-arid phytogeographic regions of Rajasthan. It requires conservation due to the over-exploitation of the natural population by local nomads and traders. Therefore, experiments were conducted in two agro-climatic zones IIA and III from their natural habitats. The impact of agro-climatic zones was studied and landrace ‘Nagori’ harvested from agro-climatic zones IIA had solid, brittle, pencil-thick roots rich in starch and total withanoloids. The microclimate, sandy soil, root thickness, root yield, starch content and root brittleness have a positive relationship. It might be due to a particular microclimate (agro-climatic zones IIA); sandy soil is rich in available potash and boron nutrient ions. The powdering and extraction industries prefer such root quality. Overall, the region-specific cultivation of landrace ‘Nagori Ashwagandha’ could be promoted for quality root production and farmers’ sustainability in the sandy soils of Central to Western Rajasthan.
