RYE 157 



Experiment Station indicated that Dean, St. Johns, 

 Petkus, and Schlanstedt were the best of ordinary varieties. 

 Nevertheless Minn. No. 2, a selection from Swedish, 

 bred at the station, continually exceeded these varieties 

 in yield, and made twice the yield an acre of rye through- 

 out the state, in a trial of 10 years (Boss, 1910, pp. 6-7). 

 In Wisconsin the varieties Ivanov and Petkus have given 

 good results. At the Ottawa, Canada, Experiment Farm, 

 spring rye, Ottawa Select, and the winter varieties, 

 Dominion, Thousandfold, and Mammoth White, have 

 done well. In the southern states, Abruzzes, grown as a 

 winter rye, has done best (Figs. 5054). 



Rye being cross-fertilized, the varieties are not numer- 

 ous. In this country there are commonly in use just the 

 two designations spring and winter. Rye makes a hardier 

 winter crop than wheat, so that spring rye is rather rare.

150. Requirements of rye. While rye does best on 

 clay or sandy loam, it is better adapted to a poor soil 

 and an unfavorable climate than either wheat or barley. 

 The soil should be well drained. Rye will stand consid- 

 erable acid in the soil, and is a good crop for heather and 

 marsh lands being reclaimed. Rye requires a smaller 

 total quantity of heat for full development than wheat, 

 and therefore matures sooner.. This advantage of rye
