ficient quantities are normally translocated to the developing gynophores 

 to insure well-developed kernels. The studies have further shown that 

 calcium may be absorbed directly by the developing pods and have 

 indicated that for proper kernel development it is very important that an 

 adequate supply of calcium be present in the zone in which the fruit are 

 formed. 



By using a technique in which the runners on one side of the plant 

 could "peg-down" in one medium and the fruit on the other side of the 

 plant could develop in a dififerent medium, Brady (36) was able to

demonstrate quite clearly the importance of proper placement of calcium. 

 Figure 5 shows that an abundance of well-developed pods were formed on 

 the side of the plant which had received calcium while relatively few 

 healthy fruit were produced on the other side in a medium which had not 

 been supplied directly with calcium. This work clearly shows that calcium 

 is not readily translocated from one part of the plant to the other. Other 

 data (table 6) reported by Colwell and Brady (45) demonstrate the im- 

 portance of proper placement in the use of calcium-bearing materials for 

 peanuts in a low-calcium environment. Gypsum supplied to the rooting 

 zone did not adequately meet the demands of the developing fruit ; how- 

 ever, large increases in shelling percentage and yield were observed 

 when the gypsum was applied to the fruiting medium. Obviously, for
