A general agreement was found throughout pickings of the different 
treatments, the largest picking of the “normal” borders was always the 
second, that of the “heavy” borders the third, while from the “medium- 
heavy” borders the second and third pickings were about equal. It 
seems that the effect of more frequent applications of water tended to 
the later maturity of the crop.
