Summary

Two field experiments were made to examine differences in wheat variety response to applied superphosphate. In the first experiment, conducted under dry conditions, both yield and yield response to superphosphate were low; in the second experiment some semi-dwarf wheats showed a greater response than standard-height wheat varieties. The semi-dwarf wheats had a greater proportion of plant phosphorus in the reproductive sections of the plant at maturity. The semi-dwarf variety Israel M 68 also showed the greatest increase in root production following the application of superphosphate.
