Culture of Raspberries 



i6q; 



about four ounces of dried fruit, which means that the grower will get 

 about seven or eight pounds of dried fruit per bushel. Moreover, the red 

 raspberry, when dried, takes on a dull red color that is not attractive. 



Yields and incomes 



The yield of the red raspberry is generally not so large as that of the 

 other bush -fruits. Card* reports an average, derived from the replies of 

 fifty-six growers, of about sixty-nine bushels, or 2,208 quarts, per acre. 

 At the Central Experimental Farm, Canada, f the Herbert produced at 

 the rate of 205 bushels, or 6,560 quarts, and the Brighton at the rate of 

 175 bushels, or 5,600 quarts, per acre. In this case the rate per acre 

 was computed from the yield of a small area, and, although such large 

 returns will not be obtained from a commercial patch, they indicate the 

 possibility of increased yields with good care. 



The average yields and incomes for western New York for the years 

 19 10 and 1909 are shown in the following table:

The average price per quart, as shown by this table, is about ten cents. 

 This is higher than the price received per quart for the other bush-fruits. 

 Considering, however, the smaller yield of the red raspberry and the fact 

 that the picking season is distributed over a longer period of time, this 

 higher price would be expected. 



Insect pests and diseases 

 The insect pests and diseases to which this fruit is subject are much 

 the same as those that attack the black raspberry and the purple-cane 

 varieties. A brief description of the most important of these pests and 

 diseases, together with the methods of control, is contained in the closing 

 pages of this lesson. 



THE BLACK RASPBERRY 



In most sections of New York the black raspberry is grown to a less 

 extent than is the red. It is of considerable importance, however, and 

 seems everywhere to be gaining in favor. The objections to it have 

 been that the fruit is seedier and smaller than the fruit of the red varieties,
