234 REporT OF THE FARM SUPERINTENDENT OF THE 
Numbers 2, 3 and 18 in this table give the results of a trial to | 
test the difference in productiveness of one, two and three-eye 
pieces, respectively, compared with whole tubers of the same — 
weight. The figures given here are the average of the yields 
obtained from each piece and the corresponding whole tuber. 
In No. 7 we have in the single-eye column the average of single 
eyes cut “deep” and “half deep,” as against the same cut 
“shallow ” or “ close.” . 
Numbers 9 and 10 give averages of results tabulated in the 
Report of the Missouri State Board of Agriculture for 1886-87, 
pages 55 and 56. 
Number 11 is the average of the two reports in the bulletins 
named. 
Number 14 gives the average of three plots of each of the two 
methods of seeding. 
2. SimiuAR WEIGHTS oF SEED Per Row In HILLs AND DRILLS. 
After the chief experiment of this series had been planted it 
was thought desirable to compare those different forms of seed 
with the similar ones, but more finely divided and planted thicker 
in the row. Accordingly the seed prepared for plats B 15 and 16 
was reserved for the one-half of each, and for the other half whole 
and half tubers were cut in thirds and planted in rows respect- 
ively adjacent to the whole and half tubers, and three, two and 
one-eye cuttings were prepared, of which three times as many 
were required for the same weight as in the lots with which they 
were compared. As in all these trials the first lots were planted — 
at intervals of two feet in the row, while in this finer series the 
pieces were planted only eight inches apart. 
The results, as shown in the table below, are in every case In — 
favor of drills. This is shown in rate per acre in the right hand 
column. But it must be borne in mind that these rates are for 
small areas, and in order to raise their yields to acre proportions - 
the differences have to be multiplied fifty times. But if on 
repetition on a fairly large scale these differences are maintained, 
there will be reason to recommend planting much nearer in the 
row than has been done in case of most of our experiments 
this year.
