Protocols for measuring seed wt for immature corn kernels

Dear Freddie,

One method that might work is to weigh ears or representative segments of
ears at harvest, predry in an oven at 42 degrees Celsius for 48 hours,
reweigh dry ears to determine moisture loss, then exise as many predried
kernels as you need for determining moisture with an NIR machine. Total
moisture would be the sum of the first moisture reading plus the second
reading obtained from the NIR.

Best regards
