The present report may be said to constitute a history of yields of staple crops from Highmore Experiment Farm secured within the period 1912 to 1930 inclusive. These yields have been secured under the climatic variations that occurred within that period; from definite crop sequences or rotations. Results of this nature are the only reliable basis for land utilization. In a number of instances the "odds" indicate that increases or decreases in yield are the resultant effect of the rotation in which the given crop occurs. Crop producers inquire in effect whether the facts established about crop sequences and rotations can be formulated into rules which tell what crops to grow. Attempts to state such rules must be a matter of logical deduction, and not absolute proof. Such deductions are nevertheless the result of research and possess value both for what they say and what they refrain from attempting to conclude.
