Extracts from a press release issued February 10, 1938 by the U. S.
Department of Agriculture on the regional cotton studies.
"Contrary to popular opinion none of the 16 varieties varied more
than 1/8, and in many instances as little as 1/16 of an inch in staple
length whether it was grown in the Mississippi Delta under the most
satisfactory moisture and soil conditions or on the western fringe of
the Cotton Belt where farmers long have planted short staple cotton for
the simple reason that they believed they could not grow longer staple
varieties."

Preliminaryj results of the Regional variety study are discussed.
In the case of staple length, the author states that variety is the
most important factor. "Contrary to popular opinion, there is seldom
more than 1/8 of an inch difference in the staple length of any
particular variety when grown in the southeast under optimum moisture
conditions, in the Mississippi Delta, or when grown under extremely
dry condition of 1935 in Oklahoma and West Texas."

"Weather conditions were favorable for cotton in 1916, the year
the parent plant was grown. The hot dry summer of 1917, however,
was unfavorable to the growth of the progeny plants. This may ac-
count in part for the fact that the average length of lint of the
progeny was slightly shorter than that of the parent plant, since a
lack of moisture is known to affect the length of lint."

"The experiments were designed as a preliminary investigation to
determine, by means of artificial shades, the effect of continual
clouds on American cotton... Shading with cotton. cloth reduced the
production ocf buds, flowers, and bolls... Plant-height was increased
and also the height of the first synpodiun, and the lint produced
was longer."

"There is very little difference in the length of staple of the
sane variety grown in the different regions o0. -aplands which grow
the principal part of the Texas cotton crop. Also it appears that
the use rf fertilizers on the sandy sils of to.stern Texas had no
appreciable effect on length of lint, but at Anjloton, on the black
prairie soils rhich are deficient in phosphcric acid, the application
of fertilizers contaling phosphoric acid increased the length of the
staple on the average 1/16 inch.tt

"In previous work to determine the effect of fertilizer on length
of fiber, the application of phosphoric acid to cotton on a soil
that responds readily to phosphoric acid apparently increased the
length of fiber. An experiment using 10 different fertilizers was
conducted in 1933 on Lake Charles clay soil, which is low in phosphoric
acid, to study the matter further. Some significant differences in
length of fiber were obtained from variously treated plats, but the
differences apparently were not caused by differences in the amounts
of nitrogen, phosphoric acid or potash, or to different rates of ap-
plication of fertilizer." Summary.

"All of the fertilizers used increased yield, size of boll, number
of bolls per plant, percentage of 5-lock bolls, size of plant, number
of fruiting branches, and earliness. Fertilizers, however, did not
increase the length of lint, nor the percentage of lint, nor did they
reduce the amount of shedding." Summary, p. 3.

"There is very little difference in the staple length of no-fertilizer
plots and those receiving commercial fertilizer, none of the staple
length values being significantly longer or shorter than those of no-
fc-rtilizcr plots. It will be noted, however, that the staple length
of the cotton grown in the plots that received manure averaged almost
1/32 inch longer than that of the cotton raised in the plots which
received no fertilizer. The difference is fairly consistent and is
significant." n. 11.

excessive water, the individual hairs became long and thin walled,
while with deficient water the hairs were greatly shortened and

bearing immature hairs."

The author by studying the reports on length of lint from various
sections of the South and by correlating length of lint with soil
type concludes that longer lint was associated with the more fertile
soils. In the case of the poor soils of the Piedmont, however, longer
lint than on the more fertile soils of the Coastal Plains was produced.
