Most crop production functions are reported as linear functions even though everyone knows they are not. The few examples of non linear crop production functions that exist in the literature are usually quadratic. As the need to know and display the correct shape of the actual function becomes greater, a mathematical expression of the function also becomes desirable. Research at the Water Studies Center, King Faisal University, indicates that the shape of several crops closely resembles the traditional hydrograph which has been represented by the expansion of the Meixner Function. This paper describes how this can be done with an example from actual data.
