INFLUENCE OF ENVIRONMENT ON SWEET CORN. 



The soil was plowed to a depth of about 5 inches, harrowed fine and 

 smooth, marked with a shovel-nosed marker, and planted 4 inches deep. 



The corn was cultivated both ways four times from 3 to 4 inches 

 deep with a one-horse cultivator, and required one hand weeding. It 

 tasseled about August 5, the Crosby corn reaching the edible condi- 

 tion between September 3 and 7, and the Stowell Evergreen between 

 September 9 and 12. 



The first frost occurred October 15, 1907, and a killing frost fol- 

 lowed on October 21. The corn was completely ripened by October 

 22 and was harvested on October 23, 1907. 



The meteorological data obtained at New Haven, Conn., are given 

 in the following table : 



Meteorological data for New Haven, Conn., 1907 . 



At the Connecticut station the rainf all was small during the growing 

 season, being 1.10 inches for July and 1.21 inches for August, while 

 during the harvesting season, September, it was excessive, attaining 

 the high figure of 7.67 inches. The percentage of sunshine, as well as 

 the mean temperature, were favorable to the growth of the plant, but 

 at the time the sugars and starch were forming in the kernels the 

 percentage of sunshine was very low, falling to 39 per cent for Sep- 

 tember. The percentage of sugars was 4.73 per cent higher in the 

 Crosby and 2.01 per cent higher in the Stowell Evergreen than it was 

 for the same varieties in 1906. The detailed analytical data follow:
