Witli parsnips, as witli carrots, potiush seems to be esperially <lesira}>le, tlie yields 

 l)einfj increased from 1 to 1.] tons i)er acre when this fertilizer Avas used over i)lats 

 similarly fertilized hut without jxitash. 



In the case of early potatoes the heaviest yields have been obtained l)y the use of 

 25 tons of manure per acre. With the late crop better yields have been obtained by 

 using lialf this amount of manure, supplemented with commercial fertilizers. In 

 the experiments with potatoes the use of potash has regularly resulted in increased 

 yields. The increase, however, has l)een nnich less with early potatoes tlian with 

 late jiotatoes. 



Potash has proved especially desirable for summer spinach, aud i)articularly so on 

 l)lats which were not maniired. 



The use of 200 lbs. of nitrate of soda per acre with phosphates and potash for 

 alfalfa resulted in increasing the yields on the average nearly 4 tons per acre. 

 Nitrate of soda was also found especially desirable in the growth <.f dwarf beans, 

 improving the quality and increasing the weight 80 per cent. 



Rhubarb dressed with commercial fertilizers when raw was far more crisp and 

 tender and required less time to cook than rhubarb grown by the aid of manure alone. 



The flavor and keeping qualities of strawl)erries were also decidedly l)etter on 

 moderately manured plats treated with commercial fertilizers, including a moderate 

 dressing of nitrate of soda, than on either heavily manured or heavily nitrated plats. 

 Moderate manuring, supplemented by phosphates and 200 Ihs. of nitrate of soda \wr 

 acre, is recommended for this crop. The nitrate of soda sliould l^e applied early in 

 the year. In the liglit of the experimental results obtained with this crop it is 

 recommended that potash be omitted from the fertilizers ajiplied. When this 

 fertilizer has been used the crop has been distinctly smaller and appre(!ial)ly later. 



For gooseberries a moderate application of manure, supplemented with a light 

 dressing of commercial fertilizers, is recommended.
