| <h2>About OPheno</h2> | |
| <p> | |
| OPheno aims to unite the full spectrum of weed‑science knowledge—from academic research and field trials to in-season field observations. By providing an open and shared home for emergence andphenology data, OPheno encourages collaboration, improves transparency, | |
| and accelerates the development of models and tools that depend on | |
| reliable, comparable observations. All datasets hosted under OPheno follow | |
| open‑science principles and aim to support anyone interested in | |
| understanding or predicting weed development. | |

| <!-- CONTRIBUTE --> | |
| <section id="contribute"> | |
| <h2>Contribute</h2> | |
| <p> | |
| Contributions from researchers, practitioners, and the community are the | |
| heart of the project. If you have observations related to weed emergence | |
| or phenology, please submit them via the | |
| <a href="https://huggingface.co/spaces/OPheno/OPheno-Submission-Portal" | |
| target="_blank" rel="noopener">portal</a>. | |
| The maintainers will review and, when feasible, curate contributions into | |
| the public datasets. Every submission not ready for curation remains | |
| accessible in the submission portal folder for transparency and future | |
| iteration. | |
