Crop Calendars

When a crop is usually sown and harvested, by jurisdiction.

Windows are transcribed from official agricultural statistics at the granularity the source publishes — begin, most-active and end dates per jurisdiction. Nothing here is generalised from a national average, and no date was derived from a seasonal description.

Where a crop has distinct winter and spring forms, they are kept separate: conflating them would put an autumn sowing date on a spring crop.
