 Jute, sisal, and manila hemp are obtained from plants grown 

 mostly in other countries. 



7. Forage Crops. — The term forage crop is used for a good

 hay, fodder, stover, straw, silage, or pasture. Crops that are 

 employed for other purposes may also be used as forage crops. 

 For example, wheat is raised principally for its grain, but it 

 may be cut green and made into hay and thus become a 

 forage crop. Forage crops will be more fully explained in 

 another chapter. 



8. Miscellaneous Crops. — There are many other crops 

 that are raised on the farm that we cannot so easily classify. 

 Some of them are : tobacco, broom corn, hops, mint, tomatoes, 

 etc. These have to be considered separately.
