230 EXPERIMENT STATION RECORD. 



FIELD CROPS. 



Experimental work [with field crops] {Orcg. Agr. Col. Bui., 1. ser., 1911, 

 No. JfS, pp. 5-27, 35, 86, SS-J/O, figs. 16). — Work at the eastern Oregon substation 

 is here reported. 



In a test of 6 varieties Sixty Day and Shadeland Challenge oats yielded 41.68 

 and 38.40 bushels per acre, respectively. Among 8 varieties tested during the 

 period 1907-1909 the 3-year average yields of Improved American and Silver 

 Mine were 83.85 and 77.52 bushels per acre, re.spectively. 



In a test of 12 barley varieties Beardless and Getekoun produced the highest 

 yields of 56.45 and 41.47 bushels per acre, respectively. In a much more exten- 

 sive test it was observed that the dark-colored barleys were the heaviest yielders, 

 and " that 30-8, 30-18, and 30-24 are probably the most promising." The com: 

 parative yields of 50 of the station's new hybrid barleys are graphically indi- 

 cated. 



Alaska and durum wheat under field conditions yielded 16.86 and 14.94 bushels 

 per acre, respectively. The station has produced a hybrid which unites the high 

 yielding qualities of Fortyfold and the nonshattering qualities of Little Club 

 besides giving the milling test desired. 



In a field test of 5 varieties of field peas White Marrowfat produced the high- 

 est yield of 13.39 bushels per acre and was regarded as a promising variety. In 

 another test of 55 varieties, conducted in cooperation with this department, 

 Brown B produced the highest yield. 



The Half Sugar mangel yielded 25.09 tons of roots and 5.59 tons of tops per 

 acre, while clover yielded nearly 2 tons of hay, 228.94 pounds of seed, and over 

 1^ tons of straw per acre, with a total estimated value of $60.13 per acre. Dwarf 

 Essex rape proved less hardy than kale, and the latter yielded 42 tons of sum- 

 mer forage per acre in a field test. A field test of seed flax produced an un- 

 satisfactory j'ield of 11.92 bushels per acre. 



lu attempts to control mustard in oats the field sprayed with iron sulphate 

 yielded 38 bushels per acre as compared with 42.86 bushels on the untreated 

 field, find 42.25 bushels on a field cultivated by a weeder, which thoroughly 

 stirred the surface soil without apparent injury to the grain. The yield of 

 mustard seed per acre was 12.65, 26.05, and 22.11 bushels per acre, respectively, 

 after the 3 treatments. 



In a test of 20 varieties of potatoes Nohoot produced the highest yield of 

 252.73 bushels ]ier acre. In a test of 10 varieties Salina Burbank potato pro- 

 duced the maximum yield of 258.8 bushels per acre. Three varieties of field 

 corn failed to ui.aure ears, but Yellow Dent matured about a dozen ears. 



Summary of fi.ve years' results of cooperative tests of varieties of corn, 

 wheat, oats, soy beans, and cowpeas, 1906-1910, A. T. Wiancko and C. O. 

 Ceomee {Indiana Sta. Bui. 149, pp. 3-23, fig. 1). — This bulletin summarizes the 

 results of the variety tests previously noted (E. S. R., 22, p. 725), and reports 

 the results secured in 1910, the yields being reported by sections of the State 

 numbered as in former years. Brief descriptions are given of the varieties 

 tested for two or more years, and the summaries include the results obtained in 

 3,731 tests covering various seasons and every soil type represented in the State. 



The table following presents the highest yields secured in each of the geo- 

 graphical sections.
