WebDec 1, 2024 · It is generally accepted that poor grain filling of rice plants under high nitrogen (N) input is due to increased competition for assimilates because high N rate usually results in large sink size with more spikelets per panicle. Starch in rice grains contributes 80–90% of the final dry weight of an unpolished grain (Yoshida, 1972; Duan and Sun, 2005).
