Phosphatic 



Nitrogenous manures stimulate leaf and stem growth, 

 and in excess do so at the expense of flower production. 

 Nitrate of soda and sulphate of ammonia are the sub- 

 stances most generally used, and they are applied either 

 dry at the rate of three quarters of an ounce per square

Nitrate of potash .... i pound " " " 



Kainit 3 pounds "

 structure of the plant.
