U.S. Objective Corn Yield Data for 2024
Corn for Grain Objective Yield Data
The National Agricultural Statistics Service conducted objective yield
surveys in 10 corn producing States during 2024. Randomly selected plots in
corn for grain fields were visited monthly from September through harvest to
obtain specific counts and measurements. Data in these tables are rounded
actual field counts from this survey.
