over the entire production period. These orchards require the same 

 care and materials. 



On the other hand, the yields on certain orchards for reasons difficult 

 to determine are much higher than indicated in the standard curve. 

 Even in portions of the same orchard under the same management these 

 differences occur. While the influences of these differences financially 

 are obvious, the importance of getting good yields is made clear by the 

 comparison of low and high yields. For this purpose two additional 

 yield curves were constructed, one a yield 30 per cent below, and one 30 

 per cent above normal. (Fig. 8.)
