to 1,000 pounds per acre. The formula varies, but either the usual 

 potato fertilizer or that applied for winter forcing is most commonly- 

 employed. 



Peas. — -Garden peas are chiefly grown as a spring crop. Eleven 

 replies to inquiries were received representing 83 acres of this crop. 

 Eight growers prefer either a sandy soil or a sandy loam for peas, 

 while three express a preference for a loam. As in the case of beans, 

 over 70 per cent of the replies call for a warm, well-drained soil. 



Peas are marketed in bushel baskets, and the replies show a range 

 in yield of 30 to 80 baskets per acre, with a normal production of 

 about 50 baskets. 



Peas are also grown as an interplanted crop to a considerable extent 

 and are fertilized with reference to the accompanying crop. The 

 amounts of commercial fertilizer range from 300 to 400 pounds to 

 1,000 pounds per acre. 



Cucumber's. — Cucumbers are grown both as a field crop and under 

 frames. (See PL XII, figs. 1 and 2.) The methods of management 

 differ very markedly in the two cases. The producers growing the 

 crop under frames require a light sandy soil, and all the manuring and 

 fertilizing is on an intensified scale. As much as 50 to 60 tons of 

 stable manure per acre may be used for the forcing crop, together 

 with heavy applications of soluble fertilizers. After the earliest 

 part of the crop is harvested and all danger of frost is over, the frames 

 are removed and the vines are allowed to spread, producing a later 

 crop. The yields from this form of production are heavy and not at 

 all comparable with those of the field crop. 



The 16 replies concerning the cucumber crop were chiefly from 

 those producing the field crop. Thirteen growers, or 80 per cent, 

 prefer either a sandy soil or a sandy loam for the crop. Three are in 

 favor of a loam soil. 



The yields under field conditions range from 50 to 150 barrels per 

 acre, with a mean of about 100 barrels. 



In practically all cases stable manure is used in considerable 

 amounts. In addition commercial fertilizers are used at a rate of 

 500 to 1,500 pounds per acre, with a normal application of about 

 1,000 pounds. 



Sweet potatoes. — Of the 15 replies received from growers of sweet 

 potatoes, 13, or 87 per cent, state a preference for a sand} 7 soil or a 

 sandy loam for this crop. 



While sweet potatoes are rather a subordinate crop in the Norfolk 

 district, a considerable acreage is grown, especially at points where 

 marketing facilities are not quite so favorable as to petmit of the 

 more intensive forms of truck growing. Usually the individual acre- 

 ages within the trucking district are small.
