KILLOUGH* OTTON is the principal cash crop in the El Paso Valley. It Was grown 0n appro-ximately 70 percent of the cultivated land 1 during the 5-year period, 1944-48. An abundance of irrigation T Water, rich alluvial soils, low rainfall and the relatively low in- , cidence of insects and diseases are conducive to the production of high yields of superior quality cotton. The average yield in gEl Paso county during these 5 years was approximately 1% gbales of lint per acre. Nearly 82 percent of the crop was of 1-3/32-inch staple or longer, and 52 percent graded Strict Mid- dling Extra White or better. Although irrigated cotto-n was penalized on the market for many years, cotton grown in the El Paso Valley is now well ‘ known for its high spinning performance and usually receives a '> E a E F l a effort of local growers to use better cultural and ginning prac- tices, and through the use of varieties with special fiber prop- erties. Except for limited acreage of American Egyptian cotton, , the area is planted exclusively to Acala 1517 and related varie- ' ties. These varieties have fibers with great tensile strength and ‘very strong yarns are obtained from the manufactured product. Approximately 100 strains of cotton have been tested for yield, staple, lint percent and other characteristics at the El Paso Val- Eley Experiment Station at Ysleta since it was established in 1942. gSome of the less promising of these varieties and strains were eliminated from the tests after 1 or 2 years, and others have been tested for longer periods. Spinning tests have been made on some of the higher-yielding varieties since 1943, and fiber strength test-s have been made on all varieties grown since 1945. l *Respectively superintendent, formerly assistant cotton breeder and assistant cotton breeder, El Paso Valley Experiment Station, Ysleta, Texas; and associate professor, Department of Agronomy, College Station, Texas. price premium. This has been brought about by the concerted A 4 BULLETIN 719, TEXAS AGRICULTURAL EXPERIMENT STATION Procedure Various agronomic data were obtained by replicated small plo procedures. The size of plots, number of replications, and plan ing and harvesting dates. varied from year to year. These ar shown in Table 6 of the Appendix. Boll size, lint percent, stapl and fiber strength were determined from replicated 15 or 50-b samples picked just prior to the first picking date and ginned asmall laboratory gin. a Seed were obtained directly from the breeders in some w; stances, and at other times through regular trade channels. Th original source of seed for all varieties and strains tested i shown in Table 5 of the Appendix. Staple. determinations forthe tests conducted 1943-47 werel made at the El Paso Classing Oflice of the Production and Mar-f keting Administration, U. S. Department of Agriculture. Sta-f. pling for the 1948 season was done by J. M. Ward, a licensed. classer at College Station. The Pressley Strength Tester was used for fiber strength de-f. terminations. These measurements were made in the fiber lab-‘ oratory at the Ysleta station except for the 1948 season, wheni they Were made by the Texas Cotton Research Committee at, Lubbock. Samples of approximately 30 pounds of seed cotton were sub; mitted to the Fiber Testing Laboratory, U. S. Department of‘ Agriculture for routine small sample spinning tests. i; Approximately 3 pounds of seed from each variety tested durl ing the 1946-48 seasons were sent to the Cottonseed Products? Research Laboratory at College Station for chemical analysis; Yield data Were- corrected for all skips over 3 feet according‘ to the formula 1 actual yield x pilot length corrected yield I plot length--(b—-3a) where (b) represents the total length of all skips. 4 feet or wider and (a) represents the number of such skips. In summarizing data from various years, adjustments Wer made to eliminate the yearly differences. Yearly correction fac; tors are shown in Table 6 of the Appendix. For example, th correction factor of 18.6 for the lint yield for 1943 indicates tha‘ the average yield of standard varieties was 18.6 pounds less tha their average for the entire 6-year period. Consequently, 18.‘, was added to the» yield of each variety grown during 1943 in‘ arriving at an adjusted yield for summary purposes. “ COTTON VARIETY TEST IN THE EL PASO VALLEY, 1943-48 5 Results Thirty-two varieties have been tested for 3 or more years. The average agronomic data recorded on these varieties are shown in Table 1. Data for the varieties tested each year are shown in Tables 7 to 12 of the Appendix. Results of fiber tests, staple and grade classifications, and carded yarn processing tests for 10 varieties which have been tested for 3 or more years are shown in Table 2. The classers and equivalent staple length of these varieties are shown in Figure 1. The equivalent staple length is. the staple length gen- erally required of average cotton to produce yarn strengths obtained for that particular sample. Data from combed yarn spinning tests for five varieties grown during 1948 are shown in Table 3. The average seed analysis of 27 varieties grown 1946-48 are shown in Table 4. Grade calculations were made in accordance with the procedure outlined by the National Cottonseed Prod- ucts Association, taking into consideration both the quantity of oil and ammonia, and the quality of the oil. Varieties included in these tests differed widely in yield. Ex- perience has shown, however, that considerable weight must be given to fiber strength and spinning performance in addition to yield, since cotton in the El Paso area. is sold principally on the basis of spinning performance. Acala 1517 WR and Acala 1517 produced yarn strength equivalents of more than 2.5-32nds inch above their classer’s staple lengths. These two, and related varieties are outstanding in this characteristic. The growing and mixing of varieties with shorter and weaker fiber would seri- Eously disrupt marketing of cotton grown in this area.
