What these dates mean in Mississippi

Planting usually runs about 60 days, from Apr 19 to Jun 17.

That start date is about 15 days earlier than the middle of the 31 places in this data set that report soybeans planting dates (May 4).

Harvest usually runs about 61 days, from Sep 10 to Nov 9.

From the start of the planting window to the start of the harvest window is about 144 days in Mississippi, a rough guide to how long the crop occupies the bed or field.

Frost-date caveat: these are published ranges for Mississippi. 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.
