| <h2>About OPheno</h2> | |
| <p> | |
| OPheno aims to unite the full spectrum of weed‑science knowledge—from academic research and field trials to industry observations and practical field experience. 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. | |
