FIELD CROPS. 



Report on field crops, J. H. Shepperd and A. M. Ten Eyck {Xorth Dakota Sta. 

 Rpt. 1901, 2)p- 44-S9, 98-104, 106, 107, fig. 1).—A general description is given of the 

 work of the agricultural department for 1901, and the results obtained in the differ-

Wlieat. — A field trial was made of 3<S varieties, of which 17 were macaroni wheats. 

 Aronautka, a macaroni variety, headed the list with a yield of 34 bu. per acre. 

 Among the blue stem varieties American, closely seconded by Selected Haynes, 

 stood first in yield. Among the Fife varieties Minnesota No. 285 stood first. The 

 average yield for 8 years of blue stem varieties was 24.9 and of Fife varieties 24 bu. 

 per acre. The average yield of the 5 leading varieties in each class in 1901 was 33.1 

 bu. per acre for macaroni wheats, 29.7 for blue stem varieties, and 27.6 for Fife varie- 

 ties. For the 3 seasons that macaroni varieties have been grown at the station they 

 have twice given better yields than the other wheats. In 1901 sowing at the rate of
