lu addition to plant breeding, some of the most important 

 lines of experiments in progress during the year 11)09 in the 

 agricultural department are the following: 



Cotton, local fertilizer experiments. 



Cotton, relative fertilizing values of ground phosphate 

 rock and acid phosphate. 



C(i)tton, continuation of the study of varieties. 



Cotton and corn, relative fertilizer requirements. 



Corn, variety, culture, and fertilizer experiments. 



Oats, variety and culture experiments. 



Crimson clover, variety and culture tests, an.l fertilizing 

 value. 



Cow];eas. variety tests. 



Sorghum, variety tests. 



Relative amounts of food produced by wrious crops suit- 

 able for hogs. 



A study of numerous forage plants, including alfalfa, 

 vetches, clovers, soybeans, kudzu, and grasses. 



Experiments in the manufacture on the farm of drain 

 tile. 



Rotation of crops. 



Effects of lime on acid soils, using a number of crops. 



The season of 1900 was a most unfavorable one for cot- 

 ton. Excessive rains during the first half of the year, a 

 period of acute drought in the late summer, and the most 

 severe injury from anthracnose. commonly called boll rot, 

 ever known during the fourteen years of the writer's con- 

 nection with this Station, all combined to cut short the 

 yield of cotton. Yet, in spite of these obstacles, the Sta- 

 tion farm averaged more than one and one-fourth bales of 

 cotton per acre. This result is believed to be chiefly due 

 to the use of crimson clover as a soil-improving crop pre- 

 ceding cotton and to the improvement of cotton by careful 

 plant breeding.

Director and Agriculturist.
