Enhancement of plant growth is an important effect of the rising concentration of atmospheric CO{sub 2}. Crops vary in response to elevated CO{sub 2}. Growth often appears greater in C{sub 3} plants than in C{sub 4} plants. But relatively little work has been done with C{sub 4} plants, and most of it has been with corn. The few existing C{sub 4} data conflict. Some studies indicate that the yield of C{sub 4} plants at elevated CO{sub 2} is about one-fourth that of C{sub 3} crops, but other studies show that C{sub 4} plants with increased CO{sub 2} yield at a rate the average for all crops
