 Table XV. — Total Yield of Htjubaedston Apple Trees. 



In the following table the average amount per tree of the 

 different classes of fruit is shown for each of the treatments. 



Table XVI. — Average Yield per Tree op Graded Fruit from Hub- 



BARDSTON TREES.

Total picked fruit 8.56 8.20 



Barrelled fruit 7.50 6.60 



Culls 1.06 1.06 



Drops 5.00 4.75 



Total yield per tree 13.56 12.95 



The apparent average loss per tree from spraying in bloom 

 was nine-tenths of a bushel of marketable fruit, but including 

 all grades it was only six-tenths of a bushel. With trees stand- 

 ing 30x30 feet apart, making 48 trees per acre, the loss of mar- 

 ketable fruit at this rate amounts to 43 bushels per acre. This 

 fruit would have readily sold at picking time for $1.25 per barrel 

 so that the apparent loss in yield might be conservatively esti- 



' It should be noted that tree No. 18 of Row 2 was somewhat smaller than 

 the other trees under experiment: also tree No. 16 of Row 3 and tree No. 16 

 of Row 4 had but a medium amount of bloom. If these are excluded the 

 average yield per tree of those sprayed in bloom Is 13.56 bushels and the 

 average per tree for trees not sprayed in bloom is 14.91 bushel per tree. In 

 this case the average for trees sprayed in bloom is 1.35 bushels per tree 

 less than for trees not sprayed in bloom.
