- Intervention effect The standard deviation of reference spacings increased from 6 to 12 km/h.
- Intervention effect Precision increased as planting speed rose from 6 to 12 km/h.
- Method / resource UAV and manual spacing measurements differed by less than 1 cm in 2022, less than in 2023.
- Method / resource Point cloud spacing correlated strongly with manual measurements.
- Method / resource The proposed method is suitable for measuring maize spacing.
- Intervention effect In 2022, grain yield did not differ across speeds.
- Intervention effect In 2022, ear parameters did not differ across speeds.
- Intervention effect In 2023, yield was greater at 6 and 9 km/h than 12 km/h.
- Intervention effect In 2023, kernel mass per ear was greater at 6 and 9 km/h than 12 km/h.
- Association Each 1 cm increase in spacing was associated with 0.73 g more kernel mass per plant.
- Association The spacing associated kernel mass increase corresponded to 58 kg/ha more yield.
