ol plant food romovcd or added to the soil as a result 

 of the two systems being tested by the experiment. 



It is phinned to make more tests in the future on 

 this question, and the cunudative effect of both systems 

 on the productive (juality of the soil will be reported 

 later. 



Amount oi- Peanuts Required to Produce One Pound 



OF Pork. 



One of the striking results in both years' tests is 

 the small amount of peanuts required to produce one 

 pound of pork. The 1917 crop yielded 1107 pounds 

 (39.5 bu.) of peanuts to the acre and produced 668.2 

 pounds of pork. One pound of pork was produced on 

 1.65 pounds of peanuts plus forage. The 1918 crop 

 yielded 846 pounds (30.2 bu.) of peanuts to the acre and 

 produced 416 pounds of pork. One pound of pork was 

 produced on 2.03 pounds of peanuts plus forage. The 

 average amount of peanuts for the two tests to produce 

 one pound of pork is 1.84 pounds. As the entire crop 

 was grazed by the hogs the peanuts were a supplement 

 to the forage crops, as the hogs ate a considerable 

 amount of peanut vine, Florida pursley, and weeds. 



In Bulletin No. 93 published by this Station, Prof. 

 J. F. Duggar states as the result of an experiment con- 

 ducted by him in 1897 that: "When fed to pigs in pens 

 only. 2.8 pounds of unhulled Spanish peanuts were 

 required to produce each pound of increase in live 

 weight." 



Carrying Capacity or One Acre of Peanut Pasture. 



The length of time one acre of peanuts will carry a 

 certain number of hogs will depend on the size of the 

 hogs and upon the yield of the crop. The following 

 table shows the average initial and average final 

 weights of the hogs and the yield of peanuts in the two 

 tests :
