June, 1933] PollIxXation and Fruit Setting in the Apple 31 



Conditions of the weather in a given section is an important considera- 

 tion in this respect. Where warm weather prevails at blossom time, the 

 pollenizers need not be so close together as where the temperature is lower. 

 Cool weather at blossoming time interferes with bee flight and under such 

 conditions, which frequently prevail throughout the apple sections of New 

 Hampshire, pollenizers should be used abundantly. One tree out of every 

 nine as a poUenizer is the minimum amount to recommend safely. Under 

 many conditions more pollenizers would be better insurance for a full crop. 



Every tree in the orchard should properly be adjacent in some direction 

 to a pollenizer. In orchards of Mcintosh where pollenizers are present only 

 in a few spots, it may be noticed that trees adjacent to the pollenizers pro- 

 duce good crops, and that the crop becomes to a striking degree progress- 

 ively less on trees farther and farther away. To forestall such results, the 

 following planting plans are suggested : 



If the varieties planted are cross fruitful, such as Mcintosh and Cortland, 

 one row of Cortland to two rows of Mcintosh would be unquestionable 

 from the pollination standpoint, unless Cortland were so desirable that the 

 rows of Cortland could alternate with the Mcintosh rows. 



Plan A 



Row 1 All Mcintosh 



2 All Cortland 



3 All Mcintosh 



4 All Mcintosh 



5 All Cortland 



6 All Mcintosh 



In this plan (A) it is understood that the trees are all to be permanent. 

 Planting all one variety in the same row would facilitate keeping the pick- 

 ers from mixing varieties in harvesting, should the two varieties ripen at 

 the same time.

In this Plan B for permanent trees, the pollenizers are placed so that 

 every tree is in contact with one. This number avoids having at least one 

 tree not adjacent to a pollenizer.
