U.S. Objective Corn Yield Data - Jan 2015
Corn for Grain Objective Yield Data
The National Agricultural Statistics Service conducted objective yield
surveys in 10 corn producing States during 2014. Randomly selected plots in
corn for grain fields were visited monthly from August through harvest to
obtain specific counts and measurements. Data in this table are rounded
actual field counts from this survey.
