CORN SOWN IX' ROWS AT DIFFERENT DISTAXCES. 



Similar experiments to those conducted last year were made with Indian corn to 

 gain information as to the distances apart the rows should be planted to give the lar- 

 gest yield per acre. Champion White Pearl, Longfellow and Selected Learning were 

 the varieties used. 



The land on which this corn was planted was a clay loam in a good state of fertil- 

 ity. The previous crop was clover, the aftermath of which was ploughed under in the 

 fall of 1900. This ground was disc-harrowed in the spring, and stable manure at the 

 rate of 20 one-horse cart loads per acre was spread broadcast and ploughed under. The 

 ground was worked up with the disc, springtooth and smoothing harrows, after which 

 the seed was sown with the seed drill in rows 21, 28, 35 and 42 inches apart. The 

 seed was sown June 8, and the crop harvested October 1. The plots were one-fortieth 

 acre each, and from the crop obtained from these plots the following yields per acre 

 have been calculated.
