Prof. ]. n. Harper, director of tn,
department Of agriculture and agri
cultural experiment station at Clem
son college, has prepared a summar,
of methods by which the farmer car
double his average yield per acre o.
cotton. 1.-The worlds demand for cot
ton," said Prof. Harper, sis increas
ing to such an extent that 1t become:
necessary for the southern farmer tc
make improvements in his methods ir
order to meet this increased demand
without increasing the area devoted
to cotton.
THE increased demand for cotton
should be met by producing more
pounds on a smaller area than Is now
devoted to that crop, thus reducing
the cost Of production by intensive
cultivation. Every acre Of well-drain-
ed land in this state that Is not plant
ed to cotton can be made to yield
twice it's present average production
AS methods for obtaining this in
creased yield, Prof. Harper offers the
following suggestions, which summa-
rize the results Of experiments publish.
ed in Bulletins 145, 14S and 162 OF
the South Carolina experiment station
The increased yields can be obtained:
/ /. BY early and deep plowing.
2. BY conserving the soil moisture
by increasing the humus content OF
the soil, and by frequent and shallow
cultivation.
3. BY turning under winter cover
crops, such as bur clover, crimson
clover, vetch and rye, which are plant
ed I'm the cotton field at the last culti-
vation,
4. BY planting cotton only on soils
we'll drained and adapted to it's culti-
S. BY giving plenty of distance in
the row and between the rows.
6. BY using the weeder frequently
during early growth.
Z. BY using large amounts OF acid
phosphate before or at the time OF
planting.
s. BY applying stable manure eth
/ er broadcast or in the drill before
planting.
8. By using potash salts on coarse
sandy soils.
10. By applying 1000 pounds OF
ground limestone per acre every ten
years.
12. By growing summer legumes to
store nitrogen in the soil.
12. BY using large amounts OF am
monia applied in the form Of blood
cotton seed meal, fish scrap, tankage
nitrate Of soda and sulphate Of ammo:
MIA before or at time Of planting, and
by later applications.
IS. By applying 100 pounds nitrate
of soda per acre when first bloom ap-
pears
IA. By liberal use of acid phosphate
IL the cotton Is making weedy
growth and not fruiting properly. :,
is. BY liberal use Of ammonia II
plants are slow Of growth and yellow
in color.
16. BY taking care never to ploW
the land when 1t is too wet.
II. BY breaking the crust after
each rain, thus saving soil moisture
and incidentally killing grass and
is. BY planting only the best va
rieties Of cotton, such as Columbia,
Hartsville, Cleveland Big Boil, Toole's
Prolific, Triumph, Cook, Brooks I'M
proved, etc.saas -..-.- -----.---...
19. BY avoiding anthracnose, or
boil rot, through proper seed selec-
ton. .,o,,
ing, early maturing, wilt resistant va
rieties.
20. BY planting early and reducing
promptly to stand.
23. BY an economical system OF
crop rotation which prevents SOILS
from washing increases the fertility
of the soil, puts soil in better physi-
cal condition, better chemical condi-
tion. better biological condition; which
prevents production, prevents in
sect depredations and plant diseases
such as cotton root rot, black knot,
bacterial blight of cotton and cotton
root louise.
"a. BY using kainit on blackjack
and calcareous soils on which cotton
Is subject to rot
