At left, fishermen buy permits at booth for fishing in API
experimental ponds. Later they have their catch weighed
to determine pond production. Below, an annual average of
4,290 permits to this 26-acre well managed pand was sold
during 8 years. This furnished enjoyment and relaxation to
the fishermen and income to the owner.

COTTON o TIME

J. T. COPE, JR., Associate Agronomist
PLANTING COTTON at the proper time
will be highly important in 1958 be-
cause good seed of recommended va-
rieties will be scarce and expensive.
When is the proper planting time?
Is early planting so important that
farmers run the risk of having to re-
plant? How late can one wait to plant
without risking a great reduction in
yield from planting too late?
Answers to these questions are based
on results of experiments on time of
planting cotton conducted at seven
widely separated locations in Alabama.
The data are presented in the table of
yields.
The best planting time for any area
covers a period of 10 to 20 days. The
best planting time within this period
varies from year to year. Many times
yields may be drastically reduced by
missing the best planting time. It is
not critical that a farmer plant on a
certain day each year, but only that he
plant as near to the best date as soil
and weather conditions will permit. He
should prepare the land and buy seed
and fertilizer well in advance of plant-
ing time so when weather conditions
become favorable he will not be de-
layed.

Extremely early planting is not nec-
essary. It is often better to wait a few
days in the recommended period than
to run an unnecessary risk of having to
replant. Planting cotton over is expen-
sive. It usually costs $5 to $6 per acre
for seed, machinery, and labor. It may
cost more in 1958. Therefore, it would
be better to wait until the soil is warm
enough to favor rapid germination and
weather prospects are for continued
favorable conditions.
Late planting is worse than early
planting in most cases. Late April plant-
ings in southern Alabama and May
plantings in all of the state usually yield
less than earlier plantings. The average
loss in yield between the last two plant-
ing dates (10 days apart) at the seven
locations was 143 lb. of seed cotton.
This was an average loss of about 15
lb. per day near the end of the plant-
ing season.
The best planting dates for the dif-
ferent sections of the State are shown
below:
Southern Alabama---- April 1 to 10
Central Alabama------ April 1 to 20
Northern Alabama---- April 10 to 30
Sand Mountain------- April 15 to 30
