Suggestions. — This crop thrives best when lmmus is very abund- 

 dant in the soil. Too much nitrogen is to be avoided, as there 

 will be a tendency to excessive growth of vines and the fruit will 

 also be large but of poor quality. However, in growing cucum- 

 bers for pickles, it may be desirable to use nitrogen and to use 

 most of it in the quickly-acting form of nitrate as this will tend 

 to cause a more abundant setting of fruit and a more rapid growth.

Suggestions. — Regular feeding and cultivating adds very much 

 to the yield of this crop. Excess of nitrogen in soils appears to 

 render plants more easily subject to mildew.
