WEATHER AND CRANBERRY PRODUCTION 



* Mostly from Table 2. page 19. Mass. Agr. Expt. Sta. Bui. 433. 1946. 



Sunshine and the Size of Massachusetts Cranberry Crops 



Franklin^ has shown that the sunshine^" of the year before the crop year is 

 an important factor in the production of the crop. He also showed that the 

 sunshine of April through September of the year before the crop year gives the 

 same degree of correlation to the size of the crop as the sunshine of the whole 

 year. No relation was found between the sunshine of any part of the crop year 

 and the size of the crop. The relation of the sunshine of each of the twenty-one 

 months preceding the crop to the size of the crop has been determined and is 

 given in Table 3.
