SUGAR CANE — TIMOTHY — TOBACCO. 6 



SUGAR CANE. 



LOUISIANA. 1886. 



Experiment by W. C. Stubbs, Director. Bulletin No. 14. 



"An inspection of our results will show that potash has increased 

 the tonnage to a marked extent, in one instance as much as 8^ tons 

 over meal and phosphate. 



"For the present it suffices to know that potassic manures used in 

 large quantities on these black lands did produce an increased tonnage. 



MISSISSIPPI. 1889. 

 By S. M. Tracy, Director. Annual Report. 



"The largest amount of total solids in the juice was from plot 7, 

 which received 100 lbs. of muriate of potash." 



TIMOTHY. 



KENTUCKY. 1889. 



Experiment by M. A. Scovell, Director. Bulletin No. 23. 

 Soil — Blue grass, wet land. 



''The potash fertilizers gave much the better results on timothy." 

 MASSACHUSETTS (Hatch Station,) 1892. 

 Bulletin No. 18, April, 1892. Special Corn Fertilizer vs. Fertilizer 

 Rich in Potash: 



"The results were similar to those obtained with corn. . . . 

 The average (of the special corn fertilizers) costing within four cents 

 of $3 more per acre, gave a crop worth at least (at current prices for 

 common millet) $6.38 less per acre than the fertilizer rich in potash, a 

 net advantage in favor of the latter fertilizer of $9.34. This result 

 affords further evidence, therefore, of the correctness of my conclusion 

 in regard to fertilizers. They are, undoubtedly, as a rule, too poor in 

 potash." 



TOBACCO. 



KENTUCKY, 1889. 



Experiment by M. A. Scovell, Director. Bulletin No. 28. Ex- 

 periments were made to determine the amount of yield from the use 

 of fertilizers. The increase of yield was very marked and seems 

 most favorable from the combination of potash and nitrogen. The 

 clear profit derived from the use of fertilizers amounted to $100.95 

 on the field treated with sulphate of potash and nitrate of soda. 

 The complete mixture yielded a profit of $107.70. 



Conclusions: ''Potash and nitrogen in combination seem to be 



required to produce the best results.
