June, 1911.] FRUIT BUD FORMATION. 7 



Plot 10. Excess Potassium. 



To be plowed in spring, annually, cultivated every two weeks till July 10; 

 then seeded with a cover crop of crimson clover. Fertilized with 0.3 lbs. 

 nitrogen, 0.5 lbs. phosphorus, and 1.5 lbs. potassium, per tree. 



Plot 11. Limed. 



To receive in addition to the treatments given plots 7, 8, 9 and 10, which 

 it crosses, 20 lbs. agricultural lime (slaked lime) per tree. 



Notes: 



Plowing, except in the case of plot 6, 4 1-2 to 5 inches in depth. 



All plots receive pruning and spraying in accordance with the best orchard 

 practice, and all receive the same treatment in these respects. 



For cover crops use 20 lbs. of seed per plot, except in plot 6, where 30 lbs. 

 are needed. 



Nitrogen is to be supplied in the following form: 1-3 nitrate of soda, 2-3 

 dried blood; phosphorus, as acid phosphate, and potassium, as high grade 

 sulphate of potash. 



REPORT OF PROGRESS IN 1908. 



The first operation performed in the orchard under experimentation con- 

 sisted in a severe pruning of all the trees. This was necessitated partly on 

 account of the fact that the orchard had been neglected in this particular 

 for many years previous, but more especially because of winter injury resulting 

 from a winter of unprecedented severity in 1906-1907. Following the pruning, 

 the various plots were fertilized in accordance with the plan, except plot 11, 

 which, for some reason unknown to the writer, was omitted. 



The author assumed charge of this project in July, 1908, and though the 

 season was then late, the work of cultivation in accordance with the plan of the 

 experiment, was undertaken immediately. All plots from number 3 to number 

 10 were placed in a condition of first-class tillage and, with the exception of 

 plot 4 which was cultivated every two weeks till September 1st, were sown with 

 cover crops of crimson clover. An excellent stand of clover resulted from 

 this seeding, a growth of six inches being secured before winter. 



Besides the work of cultivation, a further pruning was given to remove 

 dead wood and cankered branches which had appeared since the first pruning 

 or which had been overlooked at that time. All trees were also scraped and 

 washed with a preparation of whale oil soap and carbolic acid. 



The records made during the year consisted in a diary of all operations and 

 in an accurate record of the number of apples of all grades for each tree in the 

 orchard. This record appears in table No. 1.
