310 FORAGE CROPS 



can be grown wherever rutabagas are grown, and 

 will thrive if treated as described for the latter 

 crop. In the naiddle West where rutabagas have a 

 tendency to run to necks and form little root, 

 this crop is a very good substitute. So far as now 

 known, in New York the yields of the two crops 

 are about the same, but both yielded less than 

 mangels on the experiment station grounds. In 

 addition to being quite a free-growing crop, it has 

 the following advantages over rutabagas: 



"1. It is not so subject to clubroot or finger- 

 and-toe {Plasmodiophora brassicce) , and some other 

 diseases. 



"2. It withstands drought better. 



"3. It can be grown on heavier soil, as clays, 

 and does admirably on muck land. 



"4. It stands well out of the ground and can be 

 readily pastured by sheep if desired. 



"5. It has not been known to cause taint of 

 milk when fed to dairy cows. 



"6. It is I'ather better than the rutabaga in with- 

 standing frost. 



"7. It may be grown where the climate is too 

 warm for the best development of the rutabaga. 



"8. The leaves are as valuable as the stem. 



"Among well-known varieties are the White 

 Vienna (Fig. 59) , Purple Vienna, Short-top White, 

 Goliath, Carter Model."
