There was no rust. The staud was uuifonn. In spite- 

 of the severe drought every combiuation of fertilizers ef- 

 fected a high]}' profitable increase in |the crop. However, 

 when used separately, no fertilizer material exerted its full 

 efifect. 



The largest increase, 592 pounds of seed cotton per acre, 

 resulted from the use of a complete fertilizer, but in the 

 complete fertilizer 100 ])ounds of kainit was nearly as 

 effective as a larger amount. Plot 10 afforded a'net profit 

 of $10.34 per acre after paying for fertilizer and for pick- 

 ing and ginning the increase.

To unfertilized plot 80 Ibr 



To acid phosphate plot 320 lbs. 



To kainit plot 504 lbs. 



To acid phosphate and kainit plot 144 lbs.
