Kalmegh (Andrographis paniculata Nees) is an important medicinal crop widely used in allopathic and traditional system of medicine in India. The present study evaluated fourteen accessions of kalmegh (Andrographis paniculata) under the subtropical conditions of Jammu, India, aiming to identify genotypes with superior accessions of Kalmegh. The experiment was conducted at the Agroforestry Experimental Farm, Sher-e-Kashmir University of Agricultural Sciences and Technology, Jammu, using a randomized block design. Substantial variability was observed across accessions for traits including plant height, number of branches, plant spread, number of leaves, and herbage yield., Accession IC-622552 achieved the highest dry herbage yield per hectare (31.41 q ha⁻¹), closely followed by IC-622554 (29.07 q ha⁻¹). Both accessions also excelled in key growth parameters, including plant height, plant spread, number of branches, and fresh herbage weight per plant. The findings underscore the potential of IC-622552 and IC-622554 as promising candidates for enhancing medicinal plant production and supporting agricultural diversification in Jammu’s subtropical climates.
