Rice is essential for global food security, with its production significantly influenced by environmental factors during the heading-flowering stage. Recent advancements in computer vision and deep learning have improved plant phenotyping, with a study using YOLO v5, ResNet50, and DeepSORT models to automatically extract detailed panicle traits from time-series images, demonstrating high accuracy in panicle counting and precise estimation of heading date. The study also revealed the impact of nitrogen on rice panicle development, flowering duration, and grain filling initiation and duration, highlighting the potential implications for agronomic research and cultivation practices.
