U.S. Object Corn Yield Data For 2018
Corn for Grain Objective Yield Data The National Agricultural Statistics Service conducted objective yield surveys in 10 corn producing States during 2018. 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.
