40S KlEPOKT OF THE HORTICULTURAL DEPARTMENT OP THE 



blossoms failed to set yet enough did set to provide a consider- 

 able crop of fruit. 



Yield of fruit. — The Greening trees under experiment suffered 

 the loss of so much of their fruit in the wind storm of September 

 11 and 12 that no record could be made of the yield of the part 

 sprayed in bloom as distinct from the part not sprayed in bloom. 

 So far as could be determined by inspection only, there was no 

 decided difference between them. 



The Baldwins suffered much less loss of fruit during the wind 

 storm referred to than did the Greenings. Since the trees of 

 this variety which were sprayed in bloom were in a separate row 

 from the trees with which they were to be compared, the amount 

 of the drops could be ascertained and the record of their yield 

 was therefore kept. 



The amount of all the windfalls is included in the record of 

 the total yield of fruit as given in the following statement. It 

 appears from this statement that the d'rops amounted to about 

 one-third of the total yield. An inspection of the fruit both 

 before and after it was picked led to the opinion that the color of 

 the fruit was better where the trees were not sprayed in bloom 

 than it was where they were sprayed in bloom, but in size and 

 quality there was no decided difference. 



Table XVIII. — Yield of Baldwin Apple Trees. 



Not sprayed in bloom. Sprayed in bloom. 



Total bushels picked from 14 trees 129 127.5 



Total bushels drops 66 61 . 1 



Total yield 195 188.5 



Average yield per tree 13.9 13.5 



From this it appears that the average yield per tree was two- 

 fifths of a bushel less where the trees were sprayed in bloom than 

 where they were not so treated. The trees sprayed in bloom 

 averaged 6f bushels No. 1 picked fruit while the corresponding 

 trees not sprayed in bloom averaged 6^ bushels. Did thinning 

 of the fruit by spraying in bloom have the same effect as thin- 

 ning by other methods, and cause this larger yield of No. 1 fruit
