The data reported in this paper have been secured in the course of studies on the irrigation of pears carried on cooperatively by the U. S. Department of Agriculture and the Oregon Agricultural Experiment Station near Medford, Oregon. All of the work in 1930 and 1931 and the irrigation and soil moisture studies in 1932 were conducted by R. A. WORK under the direct supervision of M. R. LEWIS. Detailed studies of fruit growth and tree response were conducted in 1932 by W. W. ALDRICH. The method of interpreting the data as reported in the present paper has been developed by the senior writer.
Presented for publication as technical paper no. 207 with the approval of the Director as a contribution from the Medford Branch Experiment Station, Oregon Agricultural Experiment Station.
