throughout the entire furrow. If the plants are to be set 

 in checks 4 by 4 feet, it will be sufficient to fertilize the 

 ground for about a foot on each side of the plant. In 

 sandy soils or sandy loams, a portion of the fertilizer may 

 be withheld until the first fruits are about an inch diameter. 

 The earlier application may have more ammonia than the 

 formula calls for. One half of it should be in a quickly 

 available form. The later application should about follow 

 the above formula. In case the plants show a lack of vigor, 

 much good can be done by making a separate application 

 of nitrate of soda or nitrate of potash at the rate of about 

 a hundred pounds to the acre. 



The following table of fertilizers will give the desired 

 amounts of each element for an acre : 



Ammonia 



1000 to 1600 cottonseed meal ; or 

 600 to 1000 dried blood; or 

 400 to 650 nitrate of soda ; or 

 325 to 525 sulfate of ammonia. 



Phosphoric acid . 750 to 1200 acid phosphate. 



Potash 



1600 to 2000 kainit; or 

 275 to 450 muriate of potash ; or 

 275 to 450 high-grade sulfate of potash ; or 

 600 to 800 low-grade sulfate of potash. 



Cultivation of eggplants. 



The field cultivation of eggplants is very simple. The 

 soil should be well stirred. The cultivation should not 

 be carried to the extent of tearing the roots, however. 

 Those who are not acquainted with the root system of 

 this plant will find it profitable to dig into the soil fre- 

 quently and find out how near the top and how far the
