COTTON. 53 



growing side by side with rows of cotton, thin % and 

 unhealthy looking. 



A few years ago Prof. Atkinson, who was biologist at 

 the Station, began a series of experiments with fertilizers 

 for cotton. 



Twenty experimental plots were arranged. The plots 

 were treated differently; some of them received no manure 

 while most of the plots had applications of the various 

 fertilizer ingredients, such as acid phosphate, cottonseed 

 meal and kainit. The most striking results were obtained 

 from the use of kainit. Prof. Atkinson says: "The yield 

 on the kainit plots is increased from 70 to 100 per cent, 

 above that where no fertilizer was used, and an average of 

 40 per cent, increase over that of any other single fertilizer 

 or combination, without the kainit, used.* 9 



COTTON BLIGHT. 

 (Rust.) 



The next illustration is taken from the same bulletin. 



This shows the difference between a strong, vigorous 

 cotton plant and one that is suffering from blight or red 

 rust. No cotton planter needs to be told of the great loss 

 occasioned by this mysterious and much-dreaded disease. 

 It is more destructive in some places than in others, but 

 the damage done all through the South amounts to thou- 

 sands of dollars every season.
