One purpose of this study was to partially evaluate whether demand for nitrogen by sorghum was greater than the soil could supply at selected developmental stages under normal field conditions. Flexibility in nitrogen application through a subsurface irrigation system provides a practical means of testing for differences in yield and protein production per unit area due to the number and size of nitrogen applications and the stage of growth at the time of nitrogen application. Potential nutritional and genetic yield limitations at different developmental stages in the life cycle of sorghum could be investigated using a sub-irrigation system as well.
