SYNOPSIS The Red Prairies of Northwest Texas are favorable to the production of cotton, and the yields of a number of the best varieties in these experiments for the past eight years have averaged slightly more than one-half bale to the acre. Cotton is a crop that has the ability to take advantage of short periods of favorable growth conditions, and it is this - characteristic that makes cotton well adapted in this section, where the limiting factor in production is the distribution of summer rainfall. The shortness of the growing season is a determining factor in varietal adaptation. Varieties that have the greatest possibility in this section are fairly early in maturing, have bolls of medium size, have a high percentage of lint, and produce lint not longer than an inch and a sixteenth. Varieties in which short lint, earli- ness, and high gin-turn-out are associated produce more lint cotton to the acre than other varieties. However, this section is one that can consistently produce cotton of one-inch staple, and a number of varieties that produce lint of that length are well adapted to the prevailing conditions.

RoY QUINBY. Substation No. 12 of the Texas Agricultural Experiment Station is located in the eastern part of Hardeman County southwest of Chilli- cothe about midway between the Red and Pease Rivers, and in the sec- tion generally known as Northwest Texas. The soil composing the Station farm was derived from the weather- ing of the Permian Red Beds and belongs, in the main, to two soil types technically known as Vernon fine sandy loam and Kirkland loam, but is hardly red enough to be typical. The soil is a brown to reddish- brown loam or sandy loam to the depth of about ten inches, and is underlaid by a reddish-brown clay. This type of soil is generally re- ferred to as “mixed land” and is quite representative of a large part of this section of Texas. This Bulletin contains the results of the experiments with varieties of cotton during the years from 1919 to 1926, inclusive. The results are applicable to the Red Prairies of Northwest Texas and South- western Oklahoma. CLIMATIC CONDITIONS AND COTTON PRODUCTION The climate is classified as semi-arid. The precipitation is relatively low and unevenly distributed, and about '70 per cent of the annual pre- cipitation falls during the months from April to September.

The high evaporation reduces the effectiveness of the rainfall, especially during the summer months. Summer night temperatures as well as day temperatures are high. The average length of the frost-free period is 223 days. PRECIPITATION The monthly, summer, and annual rainfall for the years during which the experiments were conducted and the yield* of lint cotton to the acre for each year are given in Table 1. The average yield for the eight-year period was 300 pounds of lint cotton to the acre, and in six years out of the eight the yield was above this average. The yields during the period Were not in proportion to the total annual rainfall, as shown by Figure 2, or to the total summer rainfall of June, July, and August. The low yield of 1923 was due largely to damage by cotton boll worm to a crop which was replanted in June after a destructive hail. With the exception of that year, the yields refiect the distribution of summer rainfall. The distribution of summer rain- fall is the limiting ‘factor in the production of cotton in this section. The month of August is the critical period. LENGTH OF GROWING SEASON The length of the frost-free period and the prevalence of hot days and warm nights influence the production of cotton and have a decided bearing upon varietal adaptation. After September 1 the growth of cotton plants is retarded by the occurrence of cool nights, which become progressively colder as the season advances. The average date of the » first killing frost in the fall is November 6 and the season is usually of sufficient length to assure the maturity of a cotton crop; but in case the crop is planted late, or is retarded by drouth during the summer, or is planted to an unadapted variety, the shortness of the growing season may be a limiting factor in production. The length of the growing season is relatively of less importance in this section than the a distribution of summer rainfall. THE REACTION OF THE COTTON PLANT TO CLIMATIC CONDITIONS Temperature conditions usually prohibit the successful planting of cotton until May 1, and planting is done as soon after that date as E5 ‘i. 5.. ’ Test with the exception of 1923. possible. _However, it is not unusual for a good crop to be made if ééjplantingus delayed until June 15. Blooming ordinarily begins about July 10, and bolls set before Sep- tember 1 may, barring insect damage, reasonably be expected to mature. ‘The yields as given are those of Mebane cotton grown in the Cotton Spacing The yield of that year is that of Mebane cotton grown in the Cotton Variety Test.

Cotton is a plant of indeterminate growth habit, and has the ability to take advantage of short periods of favorable growth conditions. Dur- ing periods of drouth, cotton plants practically cease growth, and in case of severe and prolonged drouth may shed leaves, squares, and bolls. When drouth is broken by an effective rain, growth is immediately resumed and squares and bolls are set at the new joints on the fruiting branches. It is this characteristic of the cotton plant that makes cot- ton well adapted to this section of Texas, where summer drouths are prevalent, and where a limiting factor in production is the poor dis- tribution of summer rainfall. VARIETAL EXPERIMENTS The object of the variety experiments Was to determine the adapta- tion and the value of the various cotton varieties under the growing conditions of this section of Texas; and to discover,'if possible, the characteristics that determined the value of each variety. In the fol- lowing tables data are presented on those features of the experiment pertinent to this object. EXPERIMENTAL METHODS The methods followed in these experiments are briefly outlined belowq, The Width of row in every instance was 40 inches. The plats were thinned to single plants 18 inches apart in the row as nearly as the ' original stand would permit. There has been some change in the size and arrangement of the plats since the experiments were begun, and the changes have been to in- crease the number of replications and to decrease the size of plat. Of 10 BULLETIN NO. 366, TEXAS AGRICULTURAL EXPERIMENT STATION late years the plats have been 1/84 of an acre in area, exclusive of guard rows, and each variety has been replicated three times (making four plats in all). The outside rows of each plat were designated as guard rows and were not harvested with the remainder of the plat. Planting was done with a lister planter 0r with a two-row planter in a lister furrow. Uniform and clean cultivation was practiced and none given other than that demanded by good farm practice. All of the tests were conducted under dry-land conditions. No fertilizer was used. The land on which the experiments were conducted was in a crop rotation, with cotton following sorghum. THE RESULTS Results in 1919 The results for the year 1919 are recorded in Table 2. Conditions for plant growth during the season were not the best, but the average yield of lint cotton was almost one-half bale to the acre. There was a difference of 10'?’ pounds of lint cotton to the acre between the highest yielding variety, Half and Half, and the lowest yielding variety, Ben- nett’s Lone Star. Half and Half was the only variety that produced lint shorter than one inch in length. TablelNo. 2.-—Cotton Variety Test—419l9.

Growing conditions were fairly favorable throughout the season, and yields were slightly better than in 1919. Acala was the outstanding variety in point of yield and produced 105 pounds more lint cotton to the acre than the next highest yielding variety. The high yield made by Acala - in this year is largely responsible for the high average for the period made by this variety. Foster and Snowflake, the two longest staple varieties, produced the lowest yields of any of the ten varieties. y Kasch had lint of seve11-eighths inch in length, and was the only variety that produced lint shorter than one inch.

The growing season was very unfavorable as there was no effective rain from July 8 to Sept-ember 9. The average yield of lint was less than 100 pounds to the acre. There was no great difference in yield between the ten highest varieties. The effect of the adverse seasonal conditions upon the length of lint was noticeable, and the only varieties that produced lint longer than one inch were Acala, Lightning Express, Durango, and Snowflake. These four varieties were also the lowest in yield. 12 BULLETIN NO. 366, TEXAS AGRICULTURAL EXPERIMENT STATION Table No. 5.—Cott0n Variety Test—1922. Acre Yield, Pounds T.

The yields were lower than in any other year reported on in this Bulletin, due to adverse seasonal conditions and to insect damage. A hail on May 30 destroyed the entire crop and the test Was replanted on June 15. From the date of the last planting until August there Was no effective rainfall. During the last half of August a heavy crop of bolls was set but the greater part of it was destroyed by an infestation of cotton boll worm. The late-maturing varieties suffered most, and produced the lowest yield of lint cotton to the acre. None of the thirteen varieties pro- duced lint of less than one inch in length.

An infes- tation of cotton leaf worm destroyed the leaves of the cotton plants about October 1. This destruction of the leaves retarded the growth and development of the bolls, and yields Were lowered somewhat. The late-maturing varieties suffered most.

It Was noticeable that all the Mebane strains were above the average yield. Results in 1926 The results for the year 1926 are recorded in Table 9. Greater yields were made in this year than in any other covered in this Bul- letin. The season was one of abundant and Well distributed rainfall. A good stand did not result from the first planting and the test was replanted on May 29, which is about two Weeks later than the best planting date. Freezing temperatures Were not recorded until Novem- ber 9 but the leaves of cotton plants died about" October 1 during a period of cold, damp Weather. Late-maturing varieties Were at a dis- advantage due to late planting and to the shortened growing season. The five varieties that produced the highest yield of lint to the acre had the shortest lint and the highest percentage of lint. Lightning -Express, a variety that normally produces lint of 1%; to 13,- inches, but which matures early, yielded more lint cotton to the acre than many varieties with shorter lint but which mature late. There was a wide range in lint percentage among the varieties, and the low lint per- centages, especially those of Burnett and Mebane, T. S. No. 804, are not typical of the varieties. Unusual Weather conditions immediately preceding the maturity of the crop probably account for these low per- centages. Table No. 9.—-Cotton Variety Test-—1926. Per Cent Acre Yield, Lbs. of Crop T.

The lint length is given in sixteenths of an inch. The size of boll is indicated by the figure in the column headed “Number of Bolls to Pound.” A small number shows the boll to be large and a large number shows the boll to be small. The comparative earliness is shown under the heading “Per Cent of Crop Harvested at First Picking.” The gin turn-out or lintper cent is given under the heading “Per Gent Lint.” The per- centage of lint of all of these varieties included in this three-year period is uniformly low and particularly so in 1926. The average per cent of lint, therefore, should not be considered as the ginning percentage of the variety, but the relative diiferences between varietiesis undoubt- edly correct. The varieties are ranked according to yield of lint cotton. Varieties that have the greatest possibility in this section are fairly early, have bolls of medium size, have a high percentage of lint, and produce lint not longer than 1 1/16 inches. Varieties in which short lint, earliness, and high gin turn-out are associated produce more lint to the acre than other varieties. However, this section is one that can consistently produce cotton of one-inch staple, and a number of vari- eties that produce lint of that length are well adapted to the prevailing conditions.

VARIETIES OF COTTON IN THE RED PRAIRIES OF NORTHWEST TEXAS 17 boll and lack of storm resistance, but might be used to advantage if replanting had to be done late in the season. (3) Mebane, T. S. 4120 and Mebane, T. S. 804 are not sold com- mercially but are types of Mebane selected and grown by the Texas Station and from which a number of strains have been and are being developed. Both types are early, produce good quality lint of 15/16 to 1 inch in length, and yield consistently. (4) Kasch is one of the best AMebane-type varieties. It produces consistently, has a high gin turn-out, and has lint of one inch in length. (5) New Boykin has been tested for only fouryears, but it is ap- parently one of the best Mebane strains. It produces well, has a high gin turn-out, and has lint of 1 1/16 inches in length. (6) Mebane and Cliett’s Superior, two Mebane-type varieties; Sun- shine, a Rowden strain; and Lone Star and Lankart, two Lone Star strains, will produce well in any but a short season. All of these vari- eties produce lint of 1 to 1 1/16 inches in length and of good quality. ('7) Acala is a variety that produces lint of good quality, having 1 1/16 to lgk-inch staple, but has not produced as well as a number of shorter staple varieties grown during the past three yea-rs. (8) Rowden is not well adapted. Bennett’s Lone Star, Belton, and Truitt were not given a trial long enough to justify conclusions. (9) Lightning Express is the most valuable of the varieties that normally produce lint longer than 1%- inches. The variety is early, but does not produce as well as a number of shorter-staple varieties. (10) Durango, Snowflake, and Foster are not recommended on ac- count of their low productiveness, low gin turn-out, and the difiiculty with which they are harvested. .
