An field experiment was conducted during kharif 2017 at ZAHRS, Brahmavara to examine the response of two rice establishment methods viz., Conventional method (20 cm × 10 cm) and SRI method (25cm × 25 cm) with five dates of transplanting viz., 3rd week of June, 1st week of July, 3rd week of July, 1st week of August and 3rd week of August. Observations were recorded in 15 days interval until crop reaches physiological maturity. The experiment was conducted by using split plot design and the treatments were replicated thrice. Results indicates that significantly higher dry matter accumulation of rice was observed in SRI method of establishment as compared to conventional method of establishment and among the dates of transplanting, 3rd week transplanting has recorded higher dry matter accumulation, efficiencies like heat use efficiency, photo thermal use efficiency and helio thermal use efficiency at physiological maturity. Higher radiation use efficiency in 3rd week of transplanting might be due to better conversion of light energy in to dry matter and better yield as compared to delay transplanting.
