Abstract: This report examines the operational practicality of using a destructive counting procedure to obtain plant component counts for the soybean objective yield survey. The study was begun in 1978, and results of the analysis using 1978 and 1979 data are found in ESS Staff Report AGESS801218 entitled, "Soybean Objective Yield Destructive Counting Study" by Dwaine C. Nelson. The present report presents the results using only data collected in Illinois, with special emphasis on 1980 data. The plant component counts obtained from the two methods (destructive and the current nondestructive methods) and the forecasting abilities of the two methods are compared. Methods of modifying the destructive count forecasting models with the hope of improving them are also examined.
