On glancing over the results obtained from the individual plots, the most striking feature is that 

 the highest and lowest yields are associated with the least and greatest percentages of Pit. The 

 highest yield was obtained from plot 5, with 1,050 Ibs. of fruit, and manured with superphosphate, 

 sulphate of potash, and ground limestone ; and the lowest yield from plot 1, with 662 Ibs. of fruit and 

 no manure. 



The greatest percentage of Pit was in plot 1, unmanured, and the least percentage hi plot 5, 

 manured, as above. So that the highest yield and the smallest percentage of Pit were associated in
