big Weld was due wholly to the methoo
of preparing the land before Seeolns-
a method which would not De unprdC-
ticable for any farmer in the state.
The cost of preparing this right KIND
of seed-bed was only S4.S5 an acre
which left a profit of $3O.Ss an acre over
the cost of preparation.
The value of early blowing was
shown emphatically. OF two fields pre-

ed from land ON which wheat was ro-
tated with corn and oats. These re-
suits were obtained from WneaI grown
this year in rotation:
Land pIowed September Is, three
inches deep, produced 2519 bushels per
acre. valued at SIS above cost OF pre-
paration.
Land plowed August Is, seven inches
deep. gave Al bushels per acre, from
which there was left $29.31' AFTER pay
ing So. 55 for cost of preparation.
Land plowed July Is, three 1nches
deep, gave a yield of A bushels per
acre, cost $4.35 to prepare, leaving
return of $3O91 after paying for the
preparation.
Land flowed July Is, seven inches
deep. produced A 2-3 bushels per acre,
the highest yield in the experiment,
cost $4S5 per acre for preparation ana
returned S30.SS per acre over cost OF
production.
with the Spalding deep tillage imple-
ment, cost $50 per acre for prepara-
ton and produced A bushels OF wheat
per acre. The crop when sold return

obtained on land cropped continuously
to wheat:
Land disked at seeding time, but not
plowed, produced 9 1-3 bushels of wheat
per acre and returned $5.51 after pay
ing for the cost of preparing the
ground.

farmers) and prepared for seeding at
a cost of $2.40 per acre, produced 16 2-3
bushels per acre, leaving $10.71 after
paying for cost of preparation.
Land plowed seven inches deep In
September, at a cost of $3.50 per acre
to pillow and prepare, made yield or
171a bushels and a return of $1l.l4
over cost of preparation.
Land plowed August Is, seven inches
deep, worked thereafter sufficiently to
kill weeds and preserve moisture,
yielded 32A bushels per acre-cost of
preparation $3.55-leaving S22.71.
Land plowed July Is (the right time)
three inches deep, (too shallow for best
results produced 211A bushels of wheat
per acre, leaving $3.50 above cost of
preparation.
Land plowed July Is, seven inches
deep. produced 35 bushels per acre. the
highest yield of the continuously CROP
ped plots, cost $4.85 to prepare the land
and returned $3211 above cost of pre-
paration.
Land listed July Is. five inches deep,

gave a yield of 291a bushels per acre,
valued at $19.82 above cost of prepara-
ton.
These results obtained this year are
corroborated by similar striking varia-
tions which have occurred in three con-
secutive years. A bulletin, giving the
details of the test, will be available to
farmers next week L. E. Call, profess
