IRust was worst on plot 5. but there was little of it on 

 ttlie kainit plots. Dry weather from June to August, fol- 

 lowed by a violent storm, greatlv reduced the vield. The 

 i«itand was good. 



In 1901. The largest increase, 448 pounds of seed cotton 

 •per acre, was from a complete fertilizer. However, in a 

 'Complete fertilizer, 100 pounds of kainit was sufficient; 

 plot 9 afforded a net profit of .fS.13 per acre. 



In 1902. In spite of the drought from April till August, 



•ootton seed meal and acid phosphate profitably increased 



the yield. Plot 5 afforded an increase of 247 pounds, or a 



net profit of iif2.54, or a few cents less than plot 10 and a 



ffew cents less than plot 9.
