Interactive Effects of Planting Density and Nitrogen Rate on Maize Root Architecture, Soil Nitrogen Cycling, and Water and Nitrogen Use Efficiencies

Optimizing planting density and nitrogen (N) application is essential for sustaining maize yield while reducing water use and N inputs. However, their interactive effects on belowground root development and the soil N environment remain poorly understood. A two-year field experim...

Missing-Depth-Tolerant Oriented Object Detection for Day-Night Apple-Harvesting Perception

Apple-harvesting perception must remain usable when depth measurements are unavailable. This study evaluates a single four-channel YOLOv8s-OBB detector that accepts RGB-D input when depth is available and RGB-Z input, with a zero-filled fourth channel, when depth is absent. Train...
