"Thus it is seen that 75 samples of 7 varieties of corn from seed grown north of 

 thirty-eighth parallel of latitude yielded an average of 25.78 bu. per acre; 49 samples 

 of the same varieties from seed grown between the thirty-eighth and thirty-fifth j)ar- 

 allel of latitude yielded an average of 32.76 bu. per acre, and 3i samples of the same 

 varieties from seed grown south of the thirty-fifth parallel yielded an average of 31.48 

 bu. per acre. The middle section averaged 6.98 bu. per acre more than the north- 

 ern and 1.28 bu. more than the southern section. . . . 



"The results of the two years' experiments indicate that seed corn grown in the 

 same or nearly the same latitude as that in which it is to be planted will give the 

 best results, and that seed grown in the neighborhood where they are to be planted 

 are preferable to those grown farther north or farther south." 



Tables showing the weather conditions from March 1 to September

Fertilizer, culture, and variety experiments on cotton, R. J. 

 Redding {Georgia Sta. Bui. Ifj^pp. 79-110). — Work in continuation 

 of that previously' reported (E. S. R., 11, p. 138). The author states 

 that the season for cotton was the most unfavorable in many years. 



In 1899 25 varieties were tested. Arranged according to rank in 

 value of 3'ield and seed produced, Culpepper Improved stood first, fol- 

 lowed by Texas Bur, Moss Improved, Schley, Russell Big Boll, Prize, 

 Lee Improved No. 2, etc. Jackson Limbless stood twenty-third in 

 the list. Moss Improved produced the largest percentage of lint, 38.8, 

 and the smallest seeds, with the exception of one variety. Shire and 

 King were the earliest varieties grown. The results of 6 years' tests 

 show that early varieties are not, as a rule, the most productive. 



The results obtained in the composite seed test, begun in 1898 (E. 

 S. R., 11, p. 138), lead to the conclusion that if the seeds of two 

 equally productive varieties, one an early and the other a late cotton, 

 be mixed, the resulting yield will be greater than that of either planted 

 alone. 



In the distance experiments it was found that with rows 1 ft. apart 

 the yield of cotton was greater with 1 plant every 18 in. than with 2 

 plants ever}^ 36 in. ; also that single plants every 12 in. in the row gave 

 larger 3delds than at greater distance. In rows of varying width and 

 with plants planted at different distances in the row the yields increased 

 in proportion as the space between plants more nearly approached a 

 square.
