Sida cordifolia commonly known as Indian ephedra belongs to family Malvaceae. The present paper highlights the effects of temperature and light exposures on the seed germination of Sida cordifolia. Seeds of Sida cordifolia were germinated temperature 400C. The maximum seed germination % was recorded at 12 hours storage in refrigerator at 5-7 0C and 12 hours in oven at 100 0C. Blue light accelerates germination percentage. The best results were obtained during rainy and summer seasons while in winter seasons the percentage of germination becomes low.
