The sorghums may be divided into two classes : ( 1 ) The sweet or 

 saccharine varieties, of which amber or orange cane is mostly grown, 

 and (2) the non-saccharine or grain sorghums, which are smaller 

 and have pithy stems, with but little sweet juice (Fig. 34). Sweet 

 sorghum is grown primarily for forage and, to a limited extent at 

 the present day, for the production of syrup. The non-saccharine 

 sorghums are grown both for grain and for forage. The grain sor- 

 ghums are represented in this country by kafir corn, durra, and 

 milo maize, and a few other varieties of minor importance. Different 

 strains of each of these are grown and possess different characteris-

 and forage to farmers in the western United States. From left to right: 1 and 2, yellow

tics that make them of special value under varying conditions. The 

 mam cultivated strains are: White and black kafir, white, brown, 

 and Sudan durra, and yellow milo. The kafirs and milo occur in 

 standard and dwarf varieties. White durra is also called Jerusalem 

 corn; brown durra, Egyptian corn, 10 and Sudan durra, feterita. 

 The grain sorghums are valuable forage and grain plants, especially 

 suited to a dry and hot climate. The most striking characteristic of 

 the grain sorghums is their ability to withstand drought, and to 

 make a good growth with but little or no rainfall. After periods 

 of protracted drought, they will resume growth as soon as water

 corn or Gypcom.
