The average yield per tree in the severely pruned plot is less than that in the unpruned, and 

 the amount of Pit is also considerably less in the latter. In the single unpruned tree the yield was 

 above the average, but the fruit was rather small. The Pit was practically a negligible quantity, 

 being only 1| per cent.

As will be seen from the above, the average yield per tree was invariably larger in the unpruned 

 plots, and the amount of Pit was smaller.
