Cyclicity of farm crop yield


, : Cyclicity of farm crop yield. Soviet Agricultural Sciences ( 12): 43-46

A mathematical model predicting the year-to-year variability in crop yields was developed using a Fourier series of harmonic variations. An analysis of yield variability was made in Belgorod region with winter wheat Mironovskaya 808 and Belgorodskaya 5 and with spring barley Nutans 518.
