From 15 to 20 pounds of seed of the white mustard are required to! 

 sow an acre, which in the climate of California yields in a few months! 

 a harvest of 1,400 pounds of seed. The plant matures its seeds well,i 

 even in the desert tracts of central Australia. It can be grown in shal- 

 low soil, even on land recently reclaimed from swamps, but it prefers 

 clayey ground. The stalks and foliage after the seed harvest serve as 

 sheep fodder. The plant can be employed with great advantage as green 

 manure. (Adapted from Mueller, Select Extra-Tropical Plants, p. 82.)
