Davana is one of the commercially important aromatic crops grown in Karnataka state, India. Agro-ecological conditions of davana growing areas of Karnataka state was characterized and evaluated. Soil parameters were correlated with herbage yield, oil content and its quality to establish soil-site suitability criteria. To identify the suitable zones for davana cultivation elsewhere in Karnataka, a GIS based agro-ecological evaluation was carried out by using soil resource information (121 soil mapping units on 1:250 K scale) of Karnataka state. Each mapping unit was evaluated by matching soil-site suitability criteria with climate and soil parameters to identify the suitable areas for davana cultivation. Around 45.2 lakh ha area is highly suitable, 65.3 lakh ha is moderately suitable, and 54.2 lakh ha is marginally suitable for davana cultivation. Highly and moderately suitable areas need to be focused for expansion of davana as a component of major cropping or farming systems and also to establish forward and backward linkages.
