19171 FIELD CROPS. 641 



and 49.2 bu. per acre, respectively. Duty-of-water experiments with spring 

 barley extending over the period of 1910-1914, inclusive, indicated the use of 

 approximately 1.5 acre-feet of water per acre as suflBcient. 



The Utah and Tennessee winter barleys yielded 69.7 and 60.8 bu. per acre, 

 resfpectively, for a 2-year average. Duty-of-water experiments with winter 

 barley extending over the 3-year period of 1913-1915 gave the best results with 

 one irrigation of about 0.43 acre-foot of water per acre applied just before 

 heading. 



The leading varieties of oats included Swedish Select, Wisconsin Pedigree 

 No. 1, and Silver Mine, with average yields of 96.6, 96.5, and 96 bu. per acre, 

 respectively. 



Duty-of-water experiments with oats indicate that the oat crop requires ap- 

 proximately 1.75 acre-feet of water per acre. 



Yields of winter grains in Illinois, W. L. Buelison and O. M. Allyn 

 (Illinois Sta. Bui. 201 (1911), pp. 96-110, figs. S).— Field tests with winter 

 varieties of wheat, rye, and barley conducted at DeKalb (DeKalb Co.), Urbana 

 (Champaign Co.), and Fairfield (Wayne Co.) are reported and briefly discussed. 

 The results of the wheat variety tests conducted at Cutler (Perry Co.) and 

 previously noted (E. S. R., 19, p. 1035) are summarized, and tests with rye, 

 barley, emmer, and oats reported for the winter of 1915-16. The data are 

 presented in tabular form. 



The winter wheat variety tests at DeKalb were begun in 1907 and Dav.'son 

 Golden Chaff employed as a standard of comparison. Turkey Red is deemed the 

 principal high-yielding variety for northern Illinois, while other high-yielding 

 varieties grown for a minimum of three years include Turkey 9-233, Malakoff 

 5-458, Minnesota Reliable, Wheedling 5-464, Kharkof, and Malakoff, with aver- 

 age yields of 37.2, 36.7, 36.1, 35.2, 32.6, and 31.4 bushels, respectively. Turkey 

 Red has given a 7-year average yield of 35.4 bu. per acre. 



Winter barley all winterkilled. Average yields of 55.5 and 47 bu. per acre, 

 respectively, were secured from four tests each of Petkus winter rye and 

 Wisconsin Pedigree rye. 



Variety tests with winter wheat at Urbana were begun in 1904, using Turkey 

 Red as a standard variety. The average yields of the leading varieties tested 

 five years or more were as follows: Turkey Red 42.4 (12 years), Malakoff 42, 

 Fultz, 42.1, Hungarian 39.7, Pesterboden 41.8, Beloglina 40.4, Kharkof 42.6, and 

 Dawson Golden Chaff 39.5 bu. per acre. Other promising strains for central 

 Illinois are Turkey Hybrid 509 and Dawson Golden Chaff 9-225. 



Tests with winter wheat at Fairfield were begun in 1906, using Fulcaster as 

 a standard variety. The following varieties have given the highest average 

 yields on a percentage basis for a minimum of three years : Fulcaster, Economy, 

 Missouri Pride, Indiana Swamp, Wheedling, Harvest King, Rudy, and Poole, 

 with 15.9 (10 years), 16.9, 15.8, 14.9, 14.5, 14.3, 12.3, and 12 bu. per acre, respec- 

 tively. Fulcaster was outyielded several years by Economy, Wheedling, Mis- 

 souri Pride, and Harvest King. The hard wheats such as Turkey Red and 

 Kharkof did not prove to be adapted to southern Illinois conditions. 



The following results were secured with winter grain at Cutler in 1916 : 

 Wisconsin Pedigree rye 43.4 bu.. Wing Black rye 46.8 bu., Salzer winter barley 

 22.7 bu., Michigan winter barley 17.5 bu., and Winter emmer 52 bu. Winter 

 oats did not prove hardy. 



The characteristics of the winter wheat varieties tested at DeKalb, Urbana, 

 and Fairfield are noted in tabular form.
