Abstract: Excerpt from the report Introduction: The 1976 Corn Growth Research Project was carried out as part of the continuing effort to develop feasible within-year forecasting techniques. The objectives of this paper are to: 1) Discuss the form of the logistic growth model and its applicability to forecasting corn yields. 2) Describe the sampling, data collection and data handling techniques involved in the 1976 Corn Research Projects. 3) Discuss the analysis that was performed on this data. This discussion will include: a) The performance of the logistic model and two homoscedastic modifications when fitted using 1976 corn growth data from Iowa and Texas. b) The use of simulated growth data to observe various model characteristics. c) The use of the logistic model to forecast plant survival. 4) Make recommendations for future research.
