BILE
Ehe black root or wilt disease of
cotton is caused by a specific fun
gus which infests the soil and finds
its way into the roots of the cotton
plant. 1t grows UP through the
water ducts and cholles the plant
to death. Nematode worms AFRAID
the roots of cotton and thereby this
fungus is enabled to gain easy ac-
cess to the roots of the plant. You
should, therefore. not plant cotton
after cowpeas and particularly after
those strains of cowpeas that are
most readily attacked by the nema-
tode worm. There are certain
strains that are resistant to damage
by this insect. sucn as the Iron ana
the Brabham. Some of the soy
beans, like the Laredo, are also re-
Slstant to this pest. The Mung
bean on the other hand appears to
be readily attacked by the nema-
tode worm. Under the circum-
stances, we would grow cotton on
land which has not been devoted to
the cultivation of peas for several
years. We also suggest that you OBJ
tain a resistant strain of cotton.
some of the Toole varieties are the
west for this purpose. We think
you can SECURE good seed within
/ the state. We believe if you will
follow the procedure outlined that
your losses from the wilt disease
will be greatly minimized this year.
Merits of Certain Strains of Soy
Beans
M. n. ", Lafayette, Ga,
writes: Can you give me any
information about the Laredo,
Biloxi and O-too-tan soy beans
AS a hay crop? Are they plant
ed in rows with a planter or can
they be drilled with grain drill?
How much seed will be required
per acre?
We have grown all the varieties
of soy beans mentioned in your let
ter here at Athens for some years
past. The O-too-tan has made the
largest yield of hay, or an average
of 1.6 tons per acre. The Laredo is
a close second, with an average
yield of 1.51 tons of hay per acre.
The Mammoth Yellow made lao
tons per acre. We have only grown
the Biloxi for two years. The aver
age yield of hay obtained is two
tons You will say, therefore, that
it is the best of the lot for hay

for a period of six years, you will
probably find that the yield will
fall below two tons. For grain
production, the Southern Prolific
stands first. The Laredo stands
second in this respect; Mammoth
Yellow. third; Biloxi, fourth while
the O-too-tan is further down the
list in this respect than a number
Of other varieties.
These beans may be interplanted
with cora or sorghum. Soy beans
do not stand shaded as well as
some other legumes. 1t is often
good practice to plant between corn
rows that are say five to six feet
apart. They may also be planted
in drills three feet apart. The seed
ing may be done with any average
planter A plate suitable for SOW
ing sorghum may be reamed out
just the least bit and used to plant
the smaller seeded varieties of soy
beans. 1t will take from four to
six pounds per acre of the smaller
seeded strains, such as the O-too-tan
and the Laredo. From ten to six
teen pounds of the larger strains
will be required. We regard the soy
bean as a crop of great promise,

seeded varieties, 1t has the advan-
tage of producing number of fine
stems; of being relatively upright
in its character of growth. and easy
to cut and cure for hay. The quail
