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