BOSTICK, LARRY W. WELLS, and BRIAN E. GAMBLE1 Introduction The number of peanut varieties available to Alabama growers has increased in recent years, thus placing greater need for unbiased performance data regarding varietal selection for production. Production and Discussion The 2011 tests were conducted at the Wiregrass Research and Extension Center in Headland, AL. In the 2011 trial, 12 entries were evaluated under irrigation and dryland conditions. The experimental design for each test was a randomized complete block consisting of two-row plots, 20 feet long, replicated four times. The irrigated tests was planted on May 11 and dryland was planted May16. Both tests were planted with a cone planter at a rate of six seed per foot of row. Recommended agronomic practices were followed regarding fertility, disease, insect, and weed control in all tests. The irrigated test entries considered to be earlier than Georgia Green in maturity were dug on September 12. This entry was AT 215. Entries with maturity near the same as Georgia Green were dug on September 19. These entries were AP-4, FloRun 107, Georgia-06G, Georgia-07W, Georgia-08V, Georgia-09B, Georgia Greener, and Tifguard. Entries moderately later than Georgia Green, Florida 07 and Georgia-02C were dug on September 29. Entries later than Georgia Green were dug October 13. This entry was Georgia-10T. The dryland test entries considered to be earlier than Georgia Green were dug on September 20. This entry was AT 215. Entries with maturity near the same as Georgia Green were dug on September 29. These entries were AP-4, FloRun 107, Georgia-06G, Georgia-07W, Georgia08V, Georgia-09B, Georgia Greener, and Tifguard. Entries moderately later than Georgia Green, Florida 07 and Georgia-02C were dug on October 13. Entries later than Georgia Green were dug October 24. This entry was Georgia-10T. The information presented here represents data from three years at one location. Yield and disease occurrence data have been subjected to an analysis of variance. This statistical evaluation determined the overall averages for all varieties, coefficient of variation (CV) and the least significant differences (LSD). The LSD values represent the difference required for the averages of two varieties to be considered statistically different. The (0.05) following the LSD value indicates that the LSD was calculated at the 95 percent level of confidence. The CV, which is expressed as a percentage, is a relative measure of variation within a set of data. CV values of 8-12 percent are generally considered acceptable for yield data of agronomic crops. CV values in the disease data are considerably higher than this. However, this is expected due to random occurrence of disease in the field. 1 Bostick is an adjunct professor of the Auburn University Department of Agronomy and Soils and Executive Vice President of Alabama Crop Improvement Association; Wells is Director and Gamble is Associate Director of the Wiregrass Research and Extension Center. 3 Size and Grade Data Terms Data was collected and averaged on samples from replicates II, III, and IV for size and grade. The samples were graded following Federal-State Inspection Service procedures for grading farmer-stock peanuts. Terms Used SMKRS count/lb. (number per pound of sound mature kernels riding screen)—Number of sound whole mature kernels from 1 pound of the shelled sample riding a 15/64 x 1-inch slotted screen or a 16/64 x 3/4-inch slotted screen for Virginia or Runner varieties, respectively. Pct. SMKRS (sound mature kernels riding screen)—Portion of shelled sample as described above. Pct. SS (sound splits)—Portion of shelled sample split or broken but not damaged. Pct. TSMK (total sound mature kernels)—Portion of the shelled sample comprised of sound mature kernels plus sound splits. Pct. OK (other kernels)—Kernels that pass through a 15/64 x 1-inch slotted screen or 16/64 x 3/4-inch slotted screen for Virginia or Runner varieties, respectively. Pct. DK (damaged kernels)—Kernels that are moldy, decayed, affected by insects or weather conditions resulting in seed coat or cotyledon discoloration or deterioration. Pct. TK (total kernels)—All shelled sample kernels including TSMK, OK, and DK. Pct. Hulls —All hulls from the shelled sample. +21.0 (Generally considered as the Jumbo commercial grade)—Portion of SMKRS riding a 21/64 x 3/4-inch slotted screen. -21.0 + 18.0 (Generally considered as the Medium commercial grade)—Portion of the SMKRS falling through a 21/64 x 3/4-inch slotted screen and riding a 18/64 x 3/4-inch slotted screen. -18.0 + 16.0 (Generally considered as the No.1 commercial grade)—Portion of the SMKRS falling through a 18/64 x 3/4-inch slotted screen and riding a 16/64 x 3/4-inch slotted screen.

(For twin-rows at 36-inch centers, divide seed per foot for single row by two to determine seed per foot for each twin-row.) To determine pounds per acre at 36-inch row spacing, use the following formula: (A) Seed per foot x linear feet in 1 acre = pounds per acre Seed count per pound (B) To determine linear feet in one acre at 36-inch row spacing: 43,560 square feet per acre = 14,520 linear feet in 1 acre 3 square feet (C) Example: 6 seed per foot x 14,520 linear feet = 109 pounds per acre 800 seed per pound 15 Tests Duration Daily Rainfall Data Recorded at the Wiregrass Research and Extension Center, Headland, Alabama 2011 DATE 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 TOTALS7 APR in 0.06 MAY in JUNE in JULY in AUG in 0.25 0.05 0.98 0.07 0.28 0.08 0.68 0.36 0.13 0.27 0.12 0.10 0.04 2.92 1.27 0.04 0.03 0.07 0.54 0.04 0.02 0.01 0.17 0.20 0.31 0.22 SEPT In 0.99 OCT in 0.03 0.03 0.14 0.02 0.42 0.10 0.59 0.09 0.07 0.07 0.21 0.04 0.42 0.22 0.21 0.01 1.39 1.53 0.01 0.34 0.15 0.28 0.30 2.89 0.21 1.81 7.58 1.59 2.14 0.75 7 Total daily rainfall from April through October, 2011 = 16.97 in; 2010 = 22.65 in; 2009 =49.16 in . 16 Tests Duration Daily Maximum Temperatures Recorded at the Wiregrass Research and Extension Center, Headland, Alabama 2011 DATE 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 APR °F 65 69 78 81 85 63 72 80 89 89 88 88 78 81 81 84 77 75 84 87 88 90 89 89 89 89 87 90 80 81 MAY °F 85 86 87 91 73 76 79 85 87 91 94 94 93 88 78 71 72 73 79 88 93 92 96 96 94 96 94 95 95 97 96 JUNE °F 96 101 99 102 98 98 101 93 95 95 97 98 100 101 100 98 98 82 96 99 97 101 98 90 92 92 95 94 96 91 JULY °F 97 99 95 94 94 93 94 98 96 96 96 85 94 97 95 86 76 87 92 92 92 94 94 94 94 94 88 89 92 93 89 AUG °F 89 89 90 91 98 93 96 93 94 94 94 95 94 96 94 90 91 95 95 97 98 96 95 95 95 95 98 97 97 97 97 SEPT °F 96 93 92 89 76 87 71 72 77 85 88 89 90 88 92 93 87 84 81 88 85 91 80 87 88 93 93 89 75 86 OCT °F 88 75 74 78 83 84 85 85 84 72 68 70 72 83 81 85 87 87 74 65 64 67 70 74 78 81 82 82 83 66 66 17 Tests Duration Daily Minimum Temperatures Recorded at the Wiregrass Research and Extension Center, Headland, Alabama 2011 DATE 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 APR °F 4. 44 50 54 45 41 43 47 66 62 64 62 49 50 53 5 45 48 50 59 66 64 64 64 65 67 68 63 51 54 MAY °F 56 63 63 50 48 51 53 49 60 67 68 66 66 63 50 52 49 48 51 58 62 65 67 64 67 68 71 66 67 73 70 JUNE °F 72 72 74 73 71 72 72 71 69 73 69 70 72 74 73 66 65 58 69 75 73 71 73 72 67 69 73 71 70 71 JULY °F 71 72 70 71 72 71 72 74 71 74 73 74 74 76 74 72 71 71 71 71 73 74 73 73 73 74 71 73 72 69 67 AUG °F 71 67 70 71 71 77 76 75 75 71 71 73 74 74 72 65 66 69 72 73 74 74 72 72 72 73 75 67 67 68 70 SEPT °F 73 69 67 70 72 61 54 55 58 59 60 63 66 65 66 58 59 65 61 62 68 69 68 66 63 67 68 65 65 63 OCT °F 51 46 48 49 51 54 55 61 65 62 64 62 61 56 53 54 57 57 50 41 41 39 39 44 50 49 41 47 50 38 48 18 DESCRIPTIONS OF 2010 PEANUT VARIETY TEST ENTRIES 1.
