INFLUENCE OF ENVIRONMENT ON SWEET CORN. 



the second day of harvest 2.97 inches of rain fell, on the third day 

 1.4 inches, on the sixth day 0.84 inch, and on the seventh day 1.12 

 inches. Such heavy precipitation would probably tend to produce 

 a corn with low total sugar content. 



Florida stood last in percentage of sugars as compared with the 

 other stations for the Stowell Evergreen and next to last for the 

 Crosby. Both varieties of corn were attacked by the worms and 

 weevils. 



SOUTH CAROLINA. 



The. field used for growing the sweet corn at the South Carolina 

 station was a plat of sandy loam about one- tenth of an acre. A 

 complete fertilizer was used, 400 pounds to the acre. The corn did 

 not make a very vigorous growth, and the ears themselves were small 

 and inferior, although the analytical data show a high percentage 

 of sugar. The Crosby corn reached the edible state July 17 and the 

 Stowell on July 24. 



Meteorological data for Clemson College, S. C., 1906. 



The number of clear days for April to July, inclusive, at Clemson 

 College was 67, which was less than in 1905, when 80 clear days 

 were recorded. The total number of inches of rainfall was less than 

 for 1905, and was very unevenly distributed; most of it fell during 

 a period when it seemed to affect the corn more. During the five 

 days previous to harvesting the corn three rains fell, on the following 

 dates: July 14, 0.9 inch; July 15, 3.06 inches; and July 16, 0.3 inch. 

 On July 17, the day on which harvest began, 1.35 inches fell; July 

 18, 0.1 inch; July 19, 1.26 inches; July 21, 1.23 inches; July 23, 1.25 

 inches; and on July 25, the last day upon which any samples were 

 pulled, 2.1 inches. This heavy rainfall undoubtedly would cause a 

 decrease in the usual amount of sugars stored. Both varieties of corn 

 were inferior in yield and quality to the crops of 1905. 



As the corn was very late in ripening, and the crop at the Maryland 

 station was ready for harvesting, only a few analyses of the Crosby 

 variety were made at Clemson College. The data obtained for both 

 varieties are as follows:
