What these dates mean in Nebraska

Planting usually runs about 35 days, from Jun 1 to Jul 5.

That start date is about 18 days later than the middle of the 9 places in this data set that report sunflowers planting dates (May 14).

Harvest usually runs about 36 days, from Oct 1 to Nov 5.

From the start of the planting window to the start of the harvest window is about 122 days in Nebraska, a rough guide to how long the crop occupies the bed or field.

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