TABLE No. 3. 



Showing Total and Average Yearly Yields per Tree. (Tew- year Period.) 

 Trees Five to Fourteen Years of Age, Inclusive. 



NOTE: No records were received on Delicious trees thirteen and fourteen 

 years of age; consequently this variety is not included in Table No. 3. 



In examining the foregoing tables (Tables Nos. 1, 2 and 3), it is important 

 to note the change in relative standing of several of the varieties. Some varieties, 

 it will be observed, are consistently high yielders, others low yielders. Other 

 varieties, again, which show comparatively low yields when five to eight years 

 of age, show comparatively high yields when a greater number of years is 

 reckoned in obtaining the average. Still other varieties, which appear to be 

 relatively heavy producers while the trees are young-, do not continue to hold their 

 place as they grow older, but are forced towards the bottom of the list. 



It will also be observed that there is a wide variation in yield among some 

 of the varieties. Generally speaking, varieties which are consistently low pro- 

 ducers year after year may be considered unsuited to the Okanagan Valley. A 

 possible exception to this rule would be the case of those small-growing varieties, 

 which are especially useful in orchards as temporary, early-bearing, filler trees; 

 the low yield per tree in these instances is due to the fact that the trees by nature 

 do not develop large frameworks with extensive bearing surfaces. 



GRADE PERCENTAGES. 



It is well known that the market value of the lower grades of fruit is con- 

 siderably below that of the best grades. The advantage, therefore, of having, in 

 a given tonnage of any one variety, a large percentage of the top grade fruit is 

 obvious. That not all apple varieties average the same percentage of fruit in the 

 three higher commercial grades is clearly shown in Table No. 4. The grade 

 percentages here shown are average for the four-year period which includes the 

 years 1917, 1918, 1919 and 1920.
