This dataset contains the meteorological and yield data used in the study titled:

**"Complex relationship between crop yields and crop growing period: The shortened growing period before flowering contributes to yield increase in common buckwheat" (DOI: 10.1371/journal.pone.0322463).**

It includes:
- Daily meteorological records (temperature, precipitation, etc.)
- Buckwheat yield data from 1993 to 2020 in Japan
- Programs for analysing the data
