36 The Bulletin. 



The question of fertilizers is so closely related to that of soils that 

 the two can hardly be separated. Soils are of all degrees of fertility^ 

 from those supporting without aid only a meager growth of vegetation 

 to the richest soils, which contain plant food far beyond the needs 

 of the crop growing upon them. The sweet potato needs a complete 

 fertilizer. Growers should know approximately the deficiencies of their 

 soil and how best to supply these deficiencies at the least cost. Under 

 ordinary conditions and on the average type of soil a fertilizer having 



Available Phosphoric Acid 6 per cent 



Nitrogen 2 per cent 



Actual Potash 7 per cent 



used at the rate of from 600 to 800 pounds an acre should produce good 

 results. 



Varieties. — The Jersey potatoes are grown to a considerable extent 

 for northern markets. They are spindle-shaped, of good size, and pro- 

 ductive. The flesh is dry and mealy. 



Southern Queen, or Blayman : The potatoes of this variety are 

 short and thick, white or light cream in color, heavy croppers and good 

 keepers. The flesh is cream colored, rather moist and sweet. Quality 

 fair. 



Pumpkin Yam: Potatoes short, spindle-shaped, sometimes round. 

 Yellow skin. Plesh is orange or yellow, moist and sweet. Good cropper. 



Georgia Yams: Roots spindle-shaped, yellow, medium size. Plesh 

 is yellow, moist, and very sweet ; rather light bearer. 



Norton Yam : This is one of the yellow varieties similar to Georgia 

 or Pumpkin yam. Potatoes are short, spindle-shaped, and yellow. 

 Flesh is moist and good quality. 



ViNELEss Yam : Plant has very short or no vines, easily cultivated. 

 Roots spindle-shaped, fair size, and white or cream color. Flesh moist 

 and sweet. Not as heavy bearer as some varieties. 



Black Spanish, or "Negro Choker" : Roots are long and crooked, 



dark purple in color. Flesh white, dry and poor quality. Used for 



stock feeding. 



TOMATOES. 



There are three general uses for which tomatoes are grown: for 

 early market; for canning; for home use and local market. Growing 

 early tomatoes for shipping to northern markets is of the greatest con- 

 cern to our coast region truckers, while growing tomatoes for canning 

 purposes is of interest to the growers of the piedmont and mountainous 

 parts of the State. 



Tomatoes can be successfully grown on various types of soils, provided 

 such soils are in proper physical condition. The selection of soils will 

 be controlled largely by the purpose for which the tomatoes are grown. 

 For early market purposes a warm sandy, or sandy loam soil overlying 

 a clay subsoil is most desirable. If this is located on a slope to the
