What these dates mean in Oklahoma

Planting usually runs about 74 days, from Apr 24 to Jul 6.

That start date is close to the middle of the 14 places in this data set that report sorghum planting dates (Apr 23).

Harvest usually runs about 85 days, from Sep 9 to Dec 2.

From the start of the planting window to the start of the harvest window is about 138 days in Oklahoma, a rough guide to how long the crop occupies the bed or field.

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