R. BREITHATJPT Superintendent INTRODUCTION The Harney Branch Station is maintained jointly by the State of Oregon, through the Oregon Agricultural College and Experiment Station.and the United States, through the F. S. Department of Agriculture, Officeof Cereal Investigations,History of the Branch Station and descriptive matter pertaining to soil, buildings, equipment, extent, and nature of the region served, etc., is given in former publications.* The work of the Branch Station has been planned and conductedon two general lines (1) Experimental, (2) Service.In the first instance, the object sought is the determination of the crops whichare practicable on dry land in Central Oregon ;the isolation, hy extensive varietal tests, of the best varieties of the best cropsimprovement of the best varieties ipossi- ble; and the cletermiiiation of the hest methods of productionthrough date- of-seeding and rate-of-seeding tests and experiments in soil tillage methods and crop rotations.In the second instance, service is rendered (1) by making known the results of these experiments through publications, direct correspondence in i'eply to inquiry, to visitors at the Branch Station and through the various agencies which now exist for thepurpose of carrying the results of Such work to the people it concerns.(2) By the increase of pure seed of the best and highest-yielding varieties of adapted crops and the distribution of the seed throughout Central Oregon by sale of it in moderate quantitios to good rarmers who grow' it for seed for themselves and their neighbors. Valuable assistanceantihelpful suggestions by members of the Oregon Experiment Stationstaff and the Office of Cereal Investigations have been given bothinrelationtothe experimental work reported here andinthe preparation of this manuscript.For this the author wishes to give full credit. Special acknowledgment is given Prof.I-I,D. Scudder for outlining the tillage and rotation experiments and other help givento Prof. Geo. R. M. A. Carleton and Mr. C. R. Ball for valuable suggestions given1-lyslop, Mr. occasions. on numerous CLIMATIC DATA Records of precipitation, temperature, evaporation, and wind velocity have been kept at the Branch Station since October, 1913.Previous 10 that time, records of precipitation and temperature had been kept at Burns, six miles vest of the Station. A careful analysis of climatic factors is essential to the most successful crop production.It is easier to fit practice to climate than climate to practice. PRECIPITATION The average annual precipitation recorded at Burns for the years 1904 to 1913, inclusive, is 12.62 inches.This is somewhat higher than w'ould Bulletin No. 119, Oregon Experiment Station. Report of the Barney Branch Station 1912-14. Farmers' Bulletin No. 800, U. S. Department of Agriculture. 6 DRY FARMING INVESTIGATIONS have been obtained at the location of the Branch Station as indicated by comparative rainfall records since that time at the two points.Since 1913, the annual precipitation both at Burns and at the Branch Station, has been very much lower than this figure. The five-year average yields as reported in this bulletin were produced on an average precipitation little more than eight inches per annum. This is a rather small amount of moisture for successful farming and probably less, in view of previous records at Burns, than average for the locality. The importance of good tfllage, however, and the use of early-maturing and drought-resisting varieties is obvious. Low precipitation in the fall is a chief limiting factor in the production of winter grain. L 1 FIG. 1.FARMERS' DAY: INSPECTION OF PLOTS; BIG BASKlT DIN- NER: STUNTS AND PROGRAM.
