What these dates mean in South Dakota

Planting usually runs about 51 days, from May 11 to Jun 30.

That start date is about 18 days later than the middle of the 14 places in this data set that report sorghum planting dates (Apr 23).

Harvest usually runs about 58 days, from Sep 21 to Nov 17.

From the start of the planting window to the start of the harvest window is about 133 days in South Dakota, a rough guide to how long the crop occupies the bed or field.

Frost-date caveat: these are published ranges for South Dakota. 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.
