THE question of what kind and amount of fertilizer will bring about the most economical returns from various crops is constantly being asked of agronomists wherever commercial fertilizer is used. The necessary information for a sound answer is often lacking. This is especially true when corn is the crop under inquiry. The attempt to find the most efficient kind and amount of fertilizer for corn has been the objective of many experiments. The results have differed a great deal depending upon the location of the experiments, soil type, weather conditions and other • factors. The only practical solution seems to be continued studies under as many representative conditions as possible on which to base recommendations. These recommendations will change necessarily as new corn varieties are developed, new fertilizers become available, and new technics of fertilizer usage and crop management are introduced. In the study reported here, information was obtained on the effect of various amounts of nitrogen, phosphoric acid, and potash applied in the fertilizer on two varieties of silage corn grown at the Rhode Island Experiment Station.
