EXPERIMENTS WITH INDIAN CORN. 



239 



The corn was planted on a sandy loam. The land was previously in clover, and 

 was manured on top of the second growth in the fall, with 25 one-horse cart loads of 

 stable manure per acre. This was ploughed under in the spring after a good growth 

 was made. The soil was worked up by going over it once each with the spade, spring- 

 tooth and smoothing harrows. No fertilizer was used. 



The corn was planted iMay ."30 in rows and hills. jVlarks were made 3 ft. apart and 

 the seed dropped, and covered with a hoe, and duplicate plots of each variety were 

 planted in hills 3 ft. apart each way. The plants in the rows were thinned from 4 to 6 

 inches apart and 3 to 5 stalks were left to a hill. Thirty -seven varieties were planted. 

 The variety named Early August came up, made weak growth of 3 or 4 inches, and died. 

 The crop was harvested October 3. The yield per acre is estimated from that obtained 

 from 2 rows each 66 feet long.
