Fruit Bud Formation — {Adams Fund) 



Work on the fruit bud formation pi'ojeet lias been divided into 

 three main lines: 1, the usual records of yieki and growth in the Wood- 

 man Orchard; 2, a more detailed study of the effect of the fertilizers 

 on the method of bearing in three of the plots of the Woodman 

 Orchard which show the widest differences; 3, the study of the rela- 

 tion *of chemical composition to jierformance in fruit bud formation. 



In the Woodman Orchard the usual records covering total yield in 

 pounds per tree, the average annual twig growth as determined by 

 20 random measurements and the increase in trunk diameter were 

 taken by G. F. Potter and S. W. Wentworth. In addition, counts were 

 made this season on the size of apples as determined by weighing two 

 or three boxes from each tree and counting the number of fruits in 

 each. The results, excepting for the data on trunk diameter, are given 

 in Table VII. 



The yield for one season is, of course, of relatively little significance 

 owing to the tendency to alternate in yield. However, it may be 

 noted that the heaviest crop this year was in Plot 9 wliich is highly 

 fertilized with nitrogen, which has the highest average 3'ield for the
