FEBRUARY, 1921. COTTON VARIETY EXPERIMENTS SUBSTATION No. 3, ANGLETON, TEXAS. BY E. B. REYNOLDS, AGRONOMIST.* Substation No. 3, of the Texas Agricultural Experiment Station, is located in the Texas Gulf Coastal Plains about forty-four miles south of Houston and thirty-eight miles southwest of Galveston. The nearest point on the Gulf of Mexico is about eighteen miles distant. The ex- periment fields of the substation farm are approximately 22.5 feet above sea level. _ The topography is prevailingly fiat with poor drainage. The soil is a black clay with a gray clay subsoil classed by the Bureau of Soils as Victoria clay. Chemical analyses show it to be low in phosphorus, and fairly Well stocked with potash and lime. The rainfall is quite frequently too heavy for maximum crop produc- tion, but in 1917 and 1918 the rainfall was low. The rainfall by months from 1914 to 1920, inclusive, is given in an appendix at the back of this bulletin. This bulletin gives briefly the results of experiments with different varieties of cotton conducted at Substation N0. 3, from 1917-1920, in- clusive. No attempt is made to go into details of these experiments. The bulletin makes available certain data on the varieties of cotton which have not heretofore been available to the general public. Variety tests of cotton have been conducted since 1913, but yields have not been secured every year, for one or more reasons. For in- stance, in 1915 the test was destroyed by a tropical storm in August; while in 1914 it was a failure on account of drouth in May followed by heavy rains. Previous to 1917 the cotton-variety tests were largely preliminary in nature, in which many of the undesirable varieties were discontinued, and other varieties added from time to time as the results warranted. All of the varieties that have been tested at Substation No. 3 are not included in this bulletin. It does include, however, several of the best-yielding varieties which have appeared each of the four years 1917- 1920, inclusive, and others which have made a creditable showing. METHOD OF CONDUCTING TESTS As a rule, the cotton in the variety tests was planted in rows three feet apart. The plants were thinned out so as to leave only one plant ‘Slviperintendent of Substation No. 3, from August. 1918, to November, 1920. Credit is due Mr. . E. Winters, Superintendent, from 1913 to 1918; also to the Division of Plant Breed- ing for participating in the work in 1919 and 1920. 6 TEXAS AGRICULTURAL EXPERIMENT STATION. every foot, but in 1918 the plants Were left 18 inches apart in the row. Ordinary clean cultivation was practiced. Fertilizers were not used in these tests except in 1917 when acid phosphate was applied. The following bulletins of the Texas Agricultural Experiment Station report part of the work conducted at Substation No. 3: Bulletin No. 172—-Sudan Grass. Bulletin No. 195-—Japanese Sugar Cane as a Forage Crop. Bulletin No. 197——-Progress Report at Substation No. 3, Angleton, Texas, 1909-1914. Bulletin No. 229—-Experiments at Substation No. 3, 1909-1916. Bulletin No. 230—Spacing of Bows in Corn and Its Effect Upon Grain Yield. (Exhausted) Bulletin No. 266—The Staple of Texas Cotton. EXPERIMENT" DATA The results of the cotton variety test for each of the four years, 1917, 1918, 1919, and 1920, are given in separate tables to afford a better idea of the comparative value of each of the more profitable varieties. For 1917 the varieties are arranged in order of lint yield, as the lint was not stapled and graded. In 1918, 1919, and 1920 the varieties are listed according to their relative values to the acre. In the making of the tabl.es for 191.8, 1919, and 1920 the length and grade of staple was considered along with the yield of lint and seed. The cotton in the test was graded and stapled by specialists from the II. S. Bureau of illarkets and Texas Agricultural and Mechanical Col- lege Extension Service (cooperating). Table 1 gives ten of the better varieties in the variety test of cotton in 1917, with yields of lint and seed. Fifty-two varieties were in the test. Kasch, Lone Star, Improved Champion, Heavy Fruiter, and Me- bane were the five highest-yielding varieties. Acala was not among the ten best varieties, but it is included because its performance in 1919 and 1920 places it among the varieties best adapted to our conditions.

Mortgage Lifter, which made the highest yield of lint, has medium large bolls and a short staple. These COTTON VARIETY EXPERIMENTS. 7 relatively low yields of lint, as compared to the yields of 1917 and 1919 and the fact that the longer-staple varieties do not appear among the highest-yielding varieties, perhaps may be due to the dry season.

No. 804), however, was perhaps the most profitable variety as sold on the ordinary market. Arranged in order of lint yield, the five best varieties are Mebane (T. S. No. 804), Union Big Boll, Acala No- 5, Mebane (T. S. No. 3635), and Kasch. Table 3.—Ten most profitable varieties in 1919.

The decimals are omitted here. - a Mebane has made the highest average yield to the acre. Further- more, it has been the most profitable variety. Kasch, Lone Star, and Acala, named in order of yield, are the other three varieties Well adapted to the conditions in this part of Texas. Lone Star on account of its staple has been slightly more profitable than Kasch. Snowflake has been the best-yielding and most profitable variety of long-staple cotton grown at Substation No. 3. The varieties in Table 5 may be placed into different groups with respect to size of boll. Mebane, Lone Star, and Kasch have large bolls, while Acala and Snowflake have smaller bolls. As an average of the four years, the following number of well-opened bolls were required to make a pound of seed cotton of the different varieties: Mebane, 62; Kasch, 60; Lone Star, 59 ; Acala, 70, and Snowflake, '78 bolls.
