e0“Across two years, the results showed that the combined use of N and K on superior and inferior spikelets significantly increased their weight by 1.29 mg and 2.31 mg, their maximum grain filling rate by 0.24 mg d −1 and 0.07 mg d −1 , and their average grain filling rate by 0.21 mg d −1 and 0.06 mg d −1 , respectively, in comparison with the control (N0K0) treatment.”
