Technical Abstract:
Increases in crop yield are due to changes in the genetic efficiency in the use of inputs. However, there are constraints on efficient use of resources, e.g., water, nitrogen, solar radiation, that limit consistent high yield response. The interactions of water, nitrogen, and light form a basis for understanding how crop production efficiency can be improved. Carbon dioxide is an input into crop production that has been overlooked and understanding this environmental component will help identify barriers to high yield production. Increasing crop production efficiency is a key to increasing crop yields.
