360 SOUTHERN FIELD CROPS 



the plants were spaced 16 inches apart, the rows being Z\ feet 

 wide ; in rows 4 feet wide, larger yields were obtained when the 

 spaces between plants were 12 or 16 inches than when the space 

 was greater. In the coast region of North Carolina at the 

 Edgecomb Test Farm, nearly similar results were obtained with 

 the Russell variety.
