The purpose of the research reported in this thesis was to compare the utilization of nitrogen and other nutrients by corn and sorghum as influenced by nitrogen fertilization under optimum moisture conditions. By measuring vegetative yield and nutrient uptake by these two crops, it was hoped that the efficiency of corn and sorghum as well as basic information on the rate of nutrient accumulation by these two crops as modified by time and rate of nitrogen application could be compared.

Field experiments at the Mead and North Platte Experiment Stations were established for a three year study of continuous cropping under the same treatments annually. Nitrogen applications of 60 and 120 pounds per acre are made at three times, spring pre-plant, planting time and summer sidedress.
