Impact of Irrigation Timing on Maize Yield: Fewer Ears and Kernels with Single Sowing Irrigation

The yield differences observed among irrigation treatments were based on the number of ears and kernels (Fig.1), which is consistent with previous research indicating that a single irrigation at sowing stage reduces both ear and kernel numbers (Gao et al., 2022; Wang et al., 2018; Zhang et al., 2020).
