 in various combinations, besides Odorless (iron; Phosphate, bone and potash, and 

 Homestead superphosphate. 



The manure was applied at the rate of 20 loads (10 cords) per acre, the ashes at 

 the rate of 40 bushels, sulphate of ammonia at the rate of 160 pounds, nitrate of 

 soda 240 pounds, muriate and sulphate of potash 240 pounds, and ground bone and 

 dissolved bonel»lack 400 pounds. The highest application to any jilat consisted of 

 a mixture of 240 jiounds of muriate of potash, 240 pounds of nitrate of soda, and 4(X) 

 pounds of ground bone, at an expense of $16 to $18 per acre. The least expensive 

 fertilizer was 240 pounds of sulphate of potash, at a cost of $3..t0. 



Four varieties were used in the test in each plat, but by an error in selecting the 

 seed only 2 of these were the same throughout, and exact comparisons can not be 

 made except of the yields of these varieties. 



The results as tabulated iiulicate that the higlie.st yield was attained 

 when .stable manure was used as a mulch betwcfii the rows. ^lanurc 

 over the seed iucivased the yield more tlian inannre undtT the serd, 

 but this result was reversed in the ease of the other fertilizers. Tlic 

 chemical fertilizers were profitably use<l. Xitroj^en perhaps had the 

 least effect, but potash and fjround bone alone or in ccunbination 

 mat<Mially increased the yield. '-Of the commercial mixtures the Odor- 

 less Phosphate made the best showinu". • • ♦ Till' Ildinesicatl super- 

 phosphate was also a profitable one to apjily."
