The following diagram shows the relative yield of the varieties 

 fruited under field culture, and the yield per acre computed from the 

 yield per row covering 900 square feet. It will be seen that the 

 results in the field do not quite agree with those obtained in the plots 

 which may be in part explained by a slight difference in the soil 

 conditions and in part by a little more thorough cultivation in the 

 latter than in the former.
