AN APPLE ORCHARD SURVEY OF ORLEANS COUNTY, NEW YORK. 467 



Undoubtedly the tilled orchards have fared better in general care. 

 Neglected orchards are likely to be in sod. This table therefore shows 

 too great a difference in favor of tillage. To eliminate other factors, 

 another computation has been made in which all neglected orchards were 

 thrown out. This excluded about half of the orchards that are regularly 

 in sod and excluded some from all classes. 



FlG. 160. York Imperial. Prised in Pennsylvania as a winter apple. 

 Of questionable value in Orleans county. 



Table 5 includes only those orchards that are fairly well cared for. 

 All have received some fertilizer and some spraying. None are badly 

 damaged by lack of fertilization, spraying, or drainage, or badly damaged 

 by disease or other causes. Of these fairly well cared for orchards, those 

 that have been tilled ten or more years gave 45 per cent larger yield than 

 those in sod ten or more years, and those tilled five or more years gave 

 15 per cent larger yield than those in sod the same period. This tabula- 

 tion doubtless gives too favorable a showing for the sod orchards, tor 

 some of the diseased ones thrown out were diseased because of the sod 

 treatment. The real difference due to tillage is probably between the 

 differences shown by tables 4 and 5.
