Experiment No. 11 (1S09-1900). 

 One acre. Soil fruiii (inivcUij to <jarden loam. Season very dry. 



Plat 1. Manure, two thousand pounds ashes; yield, three thousand six 

 hundred and sixty quarts. 



Plat 2. Five thousand pounds ashes; yield, one thousand seven hundred 

 and seventy quarts. 



Plat 3. Check; yield, one thousand six hundred and ten quarts. 



Plat 4. One thousand pounds sulfate potash; yield, one thousand three 

 hundred and ninety quarts. 



Plat 5. One thousand pounds muriate potash; yield, one thousand four 

 hundred and twenty quarts. 



Plat 6. One thousand pounds muriate potash, one thousand pounds dis- 

 solved rock; yield, one thousand seven hundred and eighty quarts. 



Plat 7. Manure, one thousand pounds dissolved rock; yield, three thous- 

 and one hundred and seventy quarts. 



Plat 8. Check; yield, one thousand five hundred and forty quarts. 



Plat 9. Two thousand pounds dissolved rock; yield, two thousand four 

 hundred and ten quarts. 



Plat 10. Two thousand pounds gypsum; yield, one thousand five hundred 

 and forty quarts. 



REM AUKS ox THE FOREGOl.XG RESULTS. t 



These tables of yields show, as would be expected, a few conflicting 

 results, but through the three years' tests the benefit of using both potash 

 and phosphoric acid may readily be seen, as also the fact that, in most 

 cases, when commercial nitrogen was used, the returns in fruit failed to 

 pay for the outlay. 



The benefits derived from the use of potash or phosphoric acid are not 

 only the increase in yields, but these materials had a tendency to harden 

 the fruit, and to give them a richer color. In every case where these have 

 been used, the -grower reports firmer and better colored berries, which 

 means better shippers and better sellers. 



It will be seen by a study of experiment 1 that when an increase from 

 two hundred to four hundred pounds of wood ashes was made, at a cost 

 of not exceeding one dollar, the yield was greater by six hundred and 

 forty quarts than when only two hundred poimds had been used. This 

 yield, figured at five cents per quart, would mean a gain of $32.20. In the 

 same table, the increase from three hundred to nine hundred pounds of 

 muriate of potash was money well invested. The first increase from three 

 hundred to six hundred pounds, at a cost of $6.20, shows a gain in yield 

 of seven hundred and ninety-two quarts with a money gain at five cents 

 a quart of $36.90. Again, increasing the amount of potash three hundred 

 pounds, making nine hundred pounds per acre at an increase in cost of 

 but $12.50, the gain in fruit is shown to be one thousand seven hundred 

 and eighty-two quarts, and the money gain $89.10. 



In experiment 2 the result of increasing from five hundred to one thous- 

 and pounds of dissolved rock, at a cost of not over ten dollars, was a 

 cash gain of $54.65. Nitrate of soda used alone gave a yield of eight
