*Yield per acre based on center row of three-row plats in 1914 and on 
single-row plats in 1912. 
of grain harvested in this manner can readily be shipped to 
the central station for threshing and estimation of yield. In 
order to secure information relative to the reliability of such 
a method the following test was made in 1917 : 
Duplicate thirtieth-acre field plats of each of seven differ- 
ent varieties or selections of winter wheat were chosen from 
among a large number of plats for this study. These plats 
measured 16 rods by 66 inches and contained eight rows. 
Twenty systematicallj^ distributed fractional areas or 
quadrates were harvested from each plat. These were 32 
inches square, contained four rows of wheat, and were 
.0001632 acre in area. Quadrates were located 10 feet from 
each end and at inter\als of 14 feet on alternate sides of the 
plat, as indicated in the following diagram.
