What these dates mean in Missouri

Planting usually runs about 61 days, from Mar 1 to Apr 30.

That start date is about 30 days earlier than the middle of the 24 places in this data set that report spring oats planting dates (Mar 31).

Harvest usually runs about 43 days, from Jun 20 to Aug 1.

From the start of the planting window to the start of the harvest window is about 111 days in Missouri, a rough guide to how long the crop occupies the bed or field.

Frost-date caveat: these are published ranges for Missouri. A northern or high-elevation site will run later than a southern or low one, and a cold wet spring can push planting past the window. Frost dates and local conditions vary; NASS state-level usual dates from 20-year progress data (Oct 2010 edition), begin ~5% and end ~95% complete. Check your last spring frost and soil temperature, and confirm with your county extension office.
