Cotton, experiments with varieties and with fertilizers, 

 J. M. McBryde, Ph. D. — The experiments with cotton carried on at 

 the experimental farms of the station during' 1888 and 1889 at Spartan- 

 burg and Darlington were continued in 1890 with very little change. 

 The results for 1888 and 1889 were reported in the Annual Eeports of 

 the station for those years (see Experiment Station Bulletin Xo. 2, 

 part II, p. 152, and Experiment Station Record, vol. iii, p. 322). This 

 bulletin records the results for 1890 and the average results for the 

 3 years. 



Every test was duplicated, its two plats being as widely separated from each 

 other as the limits of the field would permit. The same experiments were carried 

 on at both farms. These farms were situated in different sections of the State and 

 were very iinlike in their climatic surroundings and the character of their soils. 

 They agreed however in one respect, the poverty of their soils. Their fertility had 

 been greatly reduced by long years of wasteful tillage. * * * The same experi- 

 ments were continued from year to year. * * * 



The combined averages of the two farms for the 3 years cover three favorable 

 and three unfavorable seasons and are entitled to great weight as representing a 

 fair average of seasons. 



Varieties of cotton (pp. 8-29). — In 1890, 14 varieties were tested at 

 Spartanburg and 18 at Darlington. During the 3 years " the varie- 

 ties tested amounted to 50." 



Eight varietLes were tested at both farms for 3 years. Texas Wood gave the 

 best average at Spartanburg (322 pounds lint per acre), the second best average at 

 Darlington (346 pounds), aud the best combined average for the two farms(334 pounds). 

 Peterkin gave the second best average at Spartanburg (399 pounds), the best 

 average at Darlington (353 pounds), and the second best combined average (326 

 pounds). Truitt gave the fourth best average at Spartanburg (280 pounds), 

 the third best at Darlington (327 pounds), and the third best combined average 

 (303 pounds). * * * It appears that there is a close connection between the 

 yield and the percentage of lint, and that the long staple varieties do not make up 

 by any superior productiveness for their low percentages of lint. * * » 



When chissilied according to their percentages of lint, it is probable that the 



majority of the so-called varieties of cotton cultivated in this State can be divided 



into three groups, two of which appear to correspond somewhat closely with two 



clearly defined old types, the short stajde cotton and the long staple — by some regarded
