| Abstract: |
| This paper is based on the data obtained from the studies on the relationship between the biological characteristcs of wheat and the clim- atic conditions in the region.A model which emphasigen more on the term of time trend as a factor in yield forecasting is formulated and has been applied to forecasting wheat yield in the past years with favorable results. It is advisable for the local agricultural production departments to apply this model to forecasting wheat yield. |
