166 THE PEANUT— THE UNPREDICTABLE LEGUME 



may not be pronounced, it is reasonable to expect increased yields of 

 peanuts through the introduction of better varieties, by the more 

 effective control of diseases and insect pests and through the adoption of 

 better cultural practices such as the use of closer spacing. As such 

 yield increases are realized and as more nutrients are j-emoved from the 

 soil by the harvested crop, the problem of maintaining the fertility of 

 the peanut soils will undoubtedly become increasingly acute. It is likely 

 that more fertilizers may eventually have to be applied to peanuts or 

 to the other crops grown in the rotation if the productivity of peanut 

 soils is to be maintained.
