Peacock!/ We have grown a cotton variety trial at AREC, Jay for the last 13 years to determine those varieties best adapted to this area and to provide a basis for variety recommendations by the Extension Service. Variety trial results for 1992 and averages over several years are included in this report. Also included are results from variety trials grown in Santa Rosa and Escambia counties; AREC, Marianna; NFREC, Quincy; and AREC, Jay; as well as variety trials grown in Tifton, Plains, and Midville, Georgia; and Fairhope, Brewton, Headland, and Monroeville, Alabama. From comparison of these reports, one should be able to determine the cotton variety best adapted to a general area. EXPLANATION OF DATA Harvest of Seed Cotton: Tests at AREC, Jay, Santa Rosa, Fairhope, Brewton, Headland, Monroeville, Tifton, Plains, and Midville were harvested by a mechanical spindle picker. Tests at AREC, Marianna; NFREC, Quincy; and Escambia County were harvested by hand. Average yield of seed cotton was determined for each variety at each location. Lint Percentage: Seed cotton samples from each variety were ginned on a 10-saw gin. Lint percentage was calculated by dividing weight of lint by weight of unginned seed cotton and multiplying by 100. Lint Yield: Lint yield was determined by multiplying seed cotton yield by lint percentage for that variety. Lint yield from Florida tests was determined by multiplying seed cotton yield by 0.39, an average lint percentage figure. Fiber Properties; Length. For Alabama tests, this is the fiber length measured with the HVI instrument and approximates classes' staple. For Georgia tests, this is the fiber length measured with the Digital Fibrograph. The 2.5% S.L. is the length in inches and approximates classer's staple.; 50% S.L. is length in inches of the test fiber specimen spanned by 50% of the fiber scanned. S.L. is span length. Strength. A measure of the fiber strength of a bundle of fiber measured with two jaws holding the fiber bundle separated by 1/8 inch, expressed in grams force per tex. Tex is a size measurement of the fiber bundle expressed as the mass, in millimeters, of 1 meter of the fiber filaments. The data are given as the force, in grams, needed to break this bundle; also noted in Georgia data as T1. The higher the number the stronger the fiber. Elongation (Ei). A measure of the percentage stretch before the fibers break. 1/Professor and Center Director, University of Florida, Institute of Food and and Agricultural Sciences, AREC, Jay. Micronaire. This measures the fineness of the cotton fibers taken from the ginned lint. The smaller the micronaire reading, the finer and/or more immature the fibers. The desirable range of micronaire is 3.5 to 4.9. Uniformity or Uniformity Ratio (UR). Ratio' of 50% S.L. to 2.5% S.L. Earliness: Where more than one harvest was made, earliness is reported as the percentage of the total yield harvested at the first picking. Fusarium Wilt: Reaction of varieties to Fusatium oxysporium f. vasinfectum was evaluated under field conditions at the E. V. Smith Research Center at Shorter, Alabama. These data are courtesy Dr. W. C. Johnson, Professor of Agronomy and Soils, Auburn University, retired; Dr. A. J. Kappelman, Jr., USDA, ARS, Auburn Univer- sity, retired; and Kathy M. Glass, Research Assistant in Agronomy and Soils, Auburn University. RESULTS AREC, Jay: The AREC, Jay cotton variety test is a continuing evaluation of available cotton varieties from private companies and state agricultural experiment sta- tions. Breeding lines that are likely to be released are also tested. We try to test only those varieties and strains that will be adapted to the North Florida- South Alabama area. Cultural practices are those generally recommended by University of Florida to farmers. Every effort is made to test the varieties and present the results in an unbiased manner. Appropriate analyses of the yield data were made. The variability in the test was measured and expressed as a percentage of the test mean, that is,..the coefficient of variation (CV). An indication of the magnitude of difference between variety averages necessary to be considered a real difference is given for each location and is designated as the Least Significance Difference (LSD05 and LSD01). Thirty-three cotton varieties were tested in a single trial replicated four times in 1992 on a Red Bay sandy loam to determine yield. All varieties were planted April 27 at the. rate of 20. bs/acre acid delinted seed. A preplant application of 250 lbs/acre 8-24-24 was disked into the soil along with Treflan and Vernam. The stand was thinned to 3-4 plants/foot of row. Ammonium nitrate was applied as a top-dressing at 200 lbs/acre plus 7 lbs/acre nitrogen from urea two times. The plots were harvested November 18. No supplemental water or potash was applied. Yields were good for most varieties. The overall mean for the test was 965 lbs lint/acre, about 300 lbs lint/acre less than in 1991. The data on yield at AREC, Jay in 1992 along with 2-, 3-, 4-, 5-, and 6-year average yields are shown in Table 1. The highest yielding variety of the varieties grown 3 years was Deltapine DES119; the highest yielding variety of varieties grown 6 years was Stoneville. KC-311. Highest yield in 1992 was: from a variety released from the Mississippi breeding program, MD51 ne. Statewide Tests: Data on yield of several cotton varieties grown at 5 locations in North Florida are presented in Table 2. A test scheduled for Okaloosa County was never planted because of unfavorable planting conditions. The highest yielding variety from the 5-location average was MD51 ne followed closely by Chembred 1135. The highest yielding variety from the two Santa Rosa location average was MD51 ne followed by Stoneville KC-311, Suregrow 1001, and Chembred 333 (Table 3). -2- New Strains Test: Data on yield of several new strains grown in a test at AREC, Jay on Red Bay sandy loam are presented in Table 4. Of the new cotton strains, PD-5246 was high- est in yield followed by GA88-15-19, PD-5529, and Seed Source 9207. Yields were fair with an overall mean of 892 lbs lint/acre. Climatological Data: A summary of the climatological data for the Agricultural Research and Education Center, Jay for 1992 is shown in Table 5. The AREC, Jay climatological gathering location is an official weather station. Georgia Tests: Data on yield and other characteristics of cotton varieties grown at Tifton (Tables 6, 7, 8, 9), Plains (Tables 10, 11, 12), and Midville (Tables 13, 14) are presented for your perusual. Of special interest might be Table 9 which presents data on high quality (long and strong fibers with desirable micronaire) varieties that might be grown in this area. Length, strength, and fineness values for each variety in this test should be the values that could be expected from those same varieties grown in North Florida. Yields would differ. Yields in the variety trial at Tifton were excellent (Table 6) with the overall mean of the test 1427 lbs/A lint. Highest yielding variety was Stoneville KC-311 followed by Deltapine 51. There was no significance difference in yield among the first 13 entries. The new strains tests at Tifton (Tables 7, 8) show yield and other charac- teristic differences among the elite strains from breeders. Overall average yield of Test I was 1441 lbs/A lint and of Test II was 1286 lbs/A lint. The data presented in Table 9 are from high quality varieties grown at Tifton. Acala 1517-88 should have the highest strength and longest fibers and may be used as a check for length and strength of the other entries tested. Alabama Tests: Data on yield and other characteristics of cotton varieties grown at Fairhope in 1992 are presented in Table 15. The highest yielding variety in 1992 was Stone- ville X84-828. The highest yielding variety of varieties grown 3 years was Deltapine 51 followed closely by Deltapine 20.. Data on yield and other characteristics of cotton varieties grown at Brewton in 1992 are presented in Table 16. The highest yielding variety in 1992 was Stone- ville 132 followed closely by Deltapine 51. The highest yielding variety of varieties grown 3 years was Deltapine 5690 followed closely by Stoneville KC-311 and Deltapine 51. Data on yield and other characteristics of cotton varieties grown at Monroe- ville in 1992 are presented in Table 17. The highest yielding variety in 1992 was Stoneville 132 followed by Stoneville LA887. The highest yielding variety of var- ieties grown 3 years was Stoneville KC-311 followed by Deltapine 5690 and Deltapine 5415. Data on yield and other characteristics of cotton varieties grown at Headland in 1992 are presented in Table 18. The highest yielding variety in 1992 was Delta- pine 90 followed by Stoneville LA887. The highest yielding variety of varieties grown 3 years was Deltapine 90 followed by Deltapine 5690 and Stoneville KC-311. -3- Fusarium Wilt: Data from the fusarium wilt test at the E. V. Smith Research Center, Shorter, Alabama showing performance of commonly grown varieties are shown in Table 19. These entries were grown on an Independence loamy fine sand highly infested with both the fusarium wilt fungus (Fusarium oxysporium Schlect. f. vasinfectum [Atk.] Snydand Hans.) and rootknot nematodes (Meloidogyne spp.). Plots were 40-inch-wide bedded rows, 30 feet long, separated by 6-foot alleys. Four replications of the test entries and checks, arranged in a block design, were evaluated. Both suscep- tible (Rowden) and resistant (Auburn 56) cultivars were included as checks. Rowden was planted in row 5 and every tenth row thereafter and Auburn 56 was planted in row 10 and every tenth row thereafter throughout the test. Plots were planted May 14, 1992. Initial plant counts were made on June 18. Wilted plants were counted and removed July 15, August 3, August 17, and August 24. The remaining live plants were also counted and recorded August 24. Percent wilted plants was then determined and mean wilting for a given entry calculated. The data in Table 20 is a summary of the data in Table 19. The wilt percen- tage of any variety in Table 20 should be interpreted in relationship to the readings for the nearest susceptible and resistant checks. Production Costs: The estimated costs of producing an acre of cotton in North Florida and break-even prices are presented in Table 21. Recommended Varieties: Varieties recommended by the University of Florida, IFAS, Florida Extension Service that should yield well under normal conditions are as follows: Stoneville Coker 310 Deltapine 41 Stoneville Coker 315 Deltapine 50 Stoneville KC-311 Deltapine 51 Stoneville 506 Deltapine 902/ Stoneville 8251/ Deltapine 5415 Tifcot 56 Deltapine 5690 Chembred 1135 Deltapine DES119 I/Stoneville 825 is more susceptible to Fusarium wilt than any other variety on the recommended list and should not be planted on land with a history of Fusarium wilt. 2/To get the best performance from Deltapine 90, care must be taken to prevent excessive growth. A common error is to over fertilize. On the heavier soils of Florida, N fertilization should not exceed 50 lbs/A unless you have a history of Deltapine 90 performance on the soil. If too much N is applied, excessive plant growth and poor boll retention will result. In addition, lower bolls will be more susceptible to boll-rotting organisms.
