RESULTS AT BURNS, OREG. 
The Harney Branch Experiment Station is located near the town 
of Burns in the bed of an ancient lake now known as the Harney 
Valley. The soil varies from a silt loam to a very fine sandy loam. 
The altitude of the station is 4,100 feet, which is about that of the 
valley floor and lower than that of the plateau of south-central 
Oregon. The average annual precipitation during the past 12 years 
has been 11.7 inches. The station is conducted cooperatively by 
the Oregon Agricultural Experiment Station and the Office of Cereal 
Investigations. 
The station was established in 1912, and the first crop was grown 
in 1913. Data covering the experiments of four years are given in 
Table XXIX. The principal facts are illustrated in figure 13. Four 
durum varieties were grown during the first three years, but only one 
of these, Kubanka, C. I. No. 1354, was continued in 1916. In the 
3-year period, Kubanka, C. I. No. 1354, was outyielded by all three of 
the other durums, the lead of Marouani being 3.7 bushels. In the 
same period Marouani was exceeded by all five varieties of common 
wheat in quantities ranging from 5 to 10 bushels per acre. The same 
fact holds true in the 4-year average, where Kubanka is the only 
durum and the yields of the common wheat exceed that of Kubanka 
by 8 to 1 1.5 bushels per acre. 
Table XXIX. — Annual and average yields of four varieties of durum wheat and seven 
varieties of common wheat grown at the Harney Branch Experiment Station, Burns, 
Oreg., during periods of varying length in the four years from 1913 to 1916, inclusive.
