cotton or corn and dug. Higher yields were obtained, however, when 

 the hogged peanuts were grown in rotation with a fertilized crop of corn 

 or cotton. The yield of corn grown in rotation with hogged peanuts was 

 some 17 bushels greater than when rotated with dug peanuts. Cotton 

 yields were also much greater in rotation with hogged peanuts. The
