“As previously reported, no supply of nitrogen during the critical growth period in which the plant type after heading was predetermined made the rice plant decrease the number of spikelets per unit area, length of lower three internodes and upper three leaf-blades, but increase the amount of carbohydrates in straw at heading stage, and as a result of it, favoured ripening and prevented the plant from lodging.”
