Bozarth 1 from 85 acres reports a yield of 8.1 tons p rt ,r acre, equal lo 

 16,200 pounds. 



In a field of 04 acres grown by the Department of Agriculture near 

 Washington, in 1SS3, the yield was 740,250 pounds of clean cane, or 

 11,662 pounds per acre, equal to 5.83 tons. 



At Rio Grande, according to the report of Professor Cook already 

 cited, 2 it is shown that the average yield of that plantation for live years 

 (about 1,000 acres per annum) was only 7.7 tons of unstripped and un- 

 topped canes, or of clean cane about 6 tons, equal to 12.000 pounds per 

 acre. 



TONNAGE PER ACRE DETERMINED BY THE EXPERIMENTS OF THE 

 NEW JERSEY AGRICULTURAL STATION. 3 



In 1881 the average yield at the New Jersey experiment station 4 was 

 4.84 tons, equal to 9,741 pounds per acre. 



In 1882, in fall-plowed land, the mean yield in sixteen experimental 

 plots was 8.45 tons, equal to 17,110 pounds 5 per acre. 



For the spring-plowed land the numbers are 9.84 tons per acre, equal 

 to 19,680 pounds. 6 



For 1883 the mean yield of sixteen experimental plots was 14.4 tons, 

 equal to 28,851 pounds per acre. 7 



In 1884 the mean yield of sixteen experiments was 10.30 tons, equal 

 to 20,601 pounds per acre. 8 



In 1885 the mean yield of sixteen plots was 12.48 tons, equal to 

 24,965 pounds per acre. 



In 1886 9 the mean weight of cane on fourteen fertilized plots calcu- 

 lated to 1 acre was of clean cane 10,443 pounds, equal to 5.22 tons. 



I believe a perfectly fair average of the yield per acre of sorghum, 

 taking into consideration all seasons and methods of culture and fertiliz- 

 ing, will be found by the investigation of the foregoing means.
