445. In Great Britain, the average good crop varies from 15 

 to 40 tons of bulbs &quot; topped, tailed, and well cleaned&quot; per acre, 

 according to soil, and meteorological locality ; while the tops of 

 Swedes reach as high as 1 7 tons on the same area. 



&quot; If planted 28 inches frora row to row, and 10 inches from turnip to 

 turnip, each turnip taking up 280 square inches, there would be 22,402 

 turnips, which at 3 Ibs. each is 30 tons, 6 Ibs. per acre ; at 4 Ibs. each 

 turnip, 40 tons, 8 Ibs. per acre.&quot; 



In New York and Pennsylvania 600 bushels per acre of the 

 common turnip are generally considered a good crop. The 

 farmers 1 Cabinet, in. 17, mentions an instance where 850 

 bushels were raised to the acre. The Swedes yield one-third 

 more than the common variety; of these 1200 to 1600 bushels 

 have been raised to the acre. ( Wiggins.) In Rensselaer Co., 

 N. Y. a premium was given in 1848, for a crop of the last of 

 1,238^ bushels per acre.
