USDA - Objective Yield Data for Corn
Corn for Grain Objective Yield Data The National Agricultural Statistics Service is conducting objective yield surveys in 10 corn-producing States during 2016. 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.
