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 11.5 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.
