BULLETIN 814, U. S. DEPARTMENT OE AGRICULTUEE. 



The average performance of the 2-row planter in drilling corn, 

 as reported by 136 farmers, is given in Table XI. Most of these men 

 reported that they also used a check rower. As with the check rower 

 there seems to be practically no difference between a day's work in 

 drilling in rows 40 and 42 inches apart. However, on the average 

 about 2 acres less per day are covered when checking than when 

 drilling, this reduction in acreage being due probably to the time 

 necessary to move and set the check-wire stakes, and the attention 

 that must be given to the check-rower attachment. 



Both in using a check rower and in drilling corn more men 

 reported 20 acres per day than any other amount. However, the 

 men using a check rower frequently reported from 15 to 18 acres as

 per cent of the reports on drilling gave more than 20 acres.

CULTIVATING CORN. 



Practically every farmer in the area uses the 1-row, 2-horse riding 

 cultivator. (See fig. 3.) About 40 per cent of the men stated that 

 they also use 2-row cultivators (fig. 4) , though only two men reported 

 the use of the 2-row machine exclusively. (See Table XII.)
