One farmer asked our agronomists how to get a yield estimate before harvest. Farm Journal Associate Field Agronomist Missy Bauer answers in episode 8 of Corn College TV.
· Measure out a 1000th of an acre.
· Count the ears.
· Pull 3 to 5 ears randomly to do kernel counts.
Then, here is the formula:
(Avg # of ears) x (Avg. Rows around) x (Avg. kernels long)
“You have to decide where up to start and stop counting kernels,” Bauer says. “I usually start about two rows up and at the tip, I back off a couple of rows as well because they aren’t good complete rows around. “
Bauer cautions this formula isn’t 100% accurate.
“It doesn’t take into consideration kernel fill or depth, which could be 10 to 15% difference,” she says.
