A Comparison of Annual Versus Average Optima for Fertilizer Experiments

John P. Doll

American Journal of Agricultural Economics, 1972, vol. 54, issue 2, 226-233

Abstract: Seven annual production functions estimating corn response to applied nitrogen and plant population were derived for three locations in Missouri. Annual optima varied widely about input amounts that maximized average profits for the seven-year period but, except for extreme cases, resulting average profits differed little from the maximum average profit.
