A field experiment was conducted under rainfed condition to study the effect of light intensity on yield and quality of Sida cordifolia and to find out the optimum stage of harvest for higher root yield and quality. The experiment was laid out in randomized block design with three replications. There were nine treatments comprising of stages of harvest from six months after planting to fourteen months after planting at monthly intervals. The experiment on stage of harvest was repeated under direct sunlight and shaded situation to study the effect of shade. Observations on growth characters, yield attributes, fresh and dry yields were recorded. The results indicated that vigorous plants and higher fresh and dry root yields were observed under open compared to shaded condition. Under shaded situation, the plants took more time for dry matter accumulation and higher root yield was noticed at twelve months after planting and the yield was very low compared to that under open situation. With respect to ephedrine yield also, higher yield was noticed under hundred per cent sunlight. The maximum root yield and ephedrine content were recorded at eight months after planting and further delay in harvesting showed a sharp decline in both root yield and ephedrine content. The results indicated that Sida cordiflia cannot tolerate shade and the optimum stage of harvest is eight months after planting.
