When serious trouble from diseases is to be apprehended, the plan- 

 tation may be brought into early fruiting and then destroyed before the 

 disease makes great headway. This is particularly applicable to black- 

 berries, raspberries, and strawberries. 



Yield- Tables 



Average full yields per acre of various horticultural crops 



The yields of those crops in which the salable products are equal in 

 number to the number of plants per acre, and in which the product is 

 sold by the piece, are to be calculated from the planting-tables in 

 Chap. VI — such as cabbage, celery, and the like. Usually the profits 

 are secured from yields above the average. The statements here 

 given are growers' estimates rather than census figures. 



Apples — A tree 20 to 30 years old may be expected to yield from 

 25 to 40 bushels every alternate year.
