INTRODUCTION Auburn University Commercial Vegetable Variety Trials: Committed to Support the Industry Eric Simonne The vegetable industry is expanding in Alabama. To support this developing sector of Alabama agribusiness, the Department of Horticulture at Auburn University, supported by the Alabama Agricultural Experiment Station, is actively working to develop the information necessary to meet the industry's needs. The choice of a variety is critical in a commercial operation since a poorly adapted variety may affect yield, quality, postharvest behavior, and subsequently, income. In the spring of 1994, replicated variety trials were conducted on crops traditionally grown in Alabama, such as bell pepper, sweet corn (including sugar-enhanced and supersweet types), cantaloupe, cucumber, southernpea, yellow squash, tomato, and watermelon. Trials also included vegetables with potential as commercial crops, including zucchini squash, colored pepper, and eggplant. Production systems ranged from traditional plantings on bare ground to plastic-mulched beds combined with drip irrigation. Soils were fertilized according to recommendations by the Auburn University Soil Testing Laboratory. The actual fertilizers and chemicals used are described only to provide detailed information about the production practices employed. Mention of fertilizers or chemical names does not represent a recommendation or endorsement. A list of chemicals recommended for pest and weed control in vegetable production in Alabama may be found in IPM Commercial Vegetables: Insect, Disease, Nematode and Weed Control Recommendations (Publication 94PM-2 from the Alabama Cooperative Extension Service). Total yield and standard characteristics used to evaluate varieties were recorded for each crop. However, emphasis was also placed on evaluating varieties for marketing potential. This included grade distribution, earliness, and shelf life. Each commodity was graded according to current standards. The complete reference to these guides is included in each of the reports that follow. Earliness was evaluated by adding the harvests corresponding approximately to the first third of total production period. One-year data on shelf-life evaluation did not show sufficiently clear trends. These preliminary results will be combined with additional results and will be reported at a later date. Performance of a vegetable variety is affected by soil type, growing environment, weather conditions, and other factors. Therefore, information in this report should be used as a primary source of information to preselect varieties that showed potential for good yields and quality under Alabama's growing conditions in 1994. On-farm evaluation will test the performance of a variety under more specific conditions. The final choice of a variety may have to be adjusted after this second evaluation. The variety trial program is supported by seven outlying units of the Alabama Agricultural Experiment Station: Gulf Coast Substation in Fairhope - Superintendent Emmett Carden; Wiregrass Substation in Superintendent Henry Ivey; The Horticulture Unit of the E.V. Smith Research Center in Shorter Headland Director Jim Bannon and Unit Superintendent Jimmy Witt; Piedmont Substation in Camp HillSuperintendent Jim Pitts; Superintendent John Owen; Chilton Area Horticulture Substation in Clanton Superintendent Marlin Hollingsworth; and Sand North Alabama Horticulture Substation in Cullman Mountain Substation in Crossville Superintendent John Eason. All outlying unit personnel help make these variety trials possible. Appreciation also is extended to the agencies and seed companies that provided an abundant and diverse supply of seeds in 1994 (see Appendix). -Center - 2 ALABAMA AGRICULTURAL EXPERIMENT STATION BELL PEPPER VARIETY TRIAL Eric Simonne, Jim Bannon, John Eason, Marlin Hollingsworth, Joe Kemble, Jim Pitts, Marvin Ruf, Kenneth Short, and Jimmy Witt Bell pepper variety trials were conducted at the Horticulture Unit of the E.V. Smith Research Center (EVSRC) in Shorter, the Sand Mountain Substation (SMS) in Crossville and the North Alabama Horticulture Substation (NAHS) in Cullman. Five-week-old peppers were transplanted on May 11 at NAHS, on May 6 at SMS, and on May 4 at EVSRC in single rows on four-feet-wide, drip-irrigated beds covered with plastic. Plastic-mulch colors were white at NAHS and black at EVSRC and SMS. Within-row spacing was one foot, which created a stand of approximately 7,300 plants per acre. At EVSRC, beds were fumigated with methyl bromide at a rate of 400 pounds per acre eight weeks before transplanting. A combination of 16-0-0, 0-460, and 0-0-60 was broadcast-applied preplant to provide 75 pounds of nitrogen (N), 60 pounds of phosphorus (P), and 120 pounds of potassium (K) per acre. Starting one week after transplanting, five pounds of N were injected weekly through the trickle-irrigation system, alternatively from 20-20-20 and potassium nitrate (KNO 3 ). Weed control consisted of an application of Roundup (2% solution) on May 12. Insect control was provided by applications of Thiodan 3EC (at a rate of two pints per acre) on May 25 and July 9, Asana XL (at a rate of seven ounces per TABLE 1.

Fungicide applications consisted of Benlate 50 WP (at a rate of one-half pound per acre) on May 25; Bravo 720 (at a rate of two quarts per acre) on June 10 and 16 and July 28; Ridomil (at a rate of two pounds per acre) on June 16 and July 9; and Dithane (at a rate of two pounds per acre) on July 18. At NAHS, beds were fumigated with methyl bromide at a rate of 400 pounds per acre on April 28. Preplant application of fertilizer provided (per acre) 30 pounds of N, 50 pounds of P, and 35 pounds of K. Between May 30 and the final harvest, injections of combinations of ammonium nitrate (NH 4 NO3 ), calcium nitrate [Ca(NO 3 )2 ], and KNO 3 were made weekly through the drip tubes. Application rates (per acre) ranged between 10-20 pounds for NH 4 NO 3 , 1050 pounds for Ca(NO 3 )2 , and 10-90 pounds for KNO 3 . Pest control consisted of an application of Penncap M (one pint in 50 gallons' per acre), Manzate (three pounds in 50 gallons per acre), and Dimethoate (one-half pint in 50 gallons per acre) on May 16 and July 6. Plants were also sprayed with Bravo (fungicide, at a rate of 1.5 pint in 50 gallons per acre); Asana (insecticide, at a rate of 9.2 ounces in 50 gallons per acre) on June 27 and July 5, 11, 19, and 25; and Ridomil (fungicide, at a rate of one pound in 50 gallons per acre) on July 5, 11, 19, and 25. At SMS, plots were fumigated with methyl bromide at a rate of 300 pounds per acre two weeks before transplanting. Preplant fertilizer provided (per acre) 30 pounds of N, 60 pounds of P, and 60 pounds of K. Starting one week after transplanting, liquid fertilizer was injected weekly through the drip tubes at a rate of five pounds of N per acre alternately from 20-20-20 and potassium nitrate (13-0-44). Weeds were controlled with applications of Poast (1%) on June 1 and July 1. An application of Sevin (insecticide) was made on June 29, at a rate of 1.25 pound per acre. '50 gallons is the total volume. SPRING 1994 COMMERCIAL VEGETABLE VARIETY TRIALS 3 Plots were harvested six times between July 19 and August 8 at NAHS, five times between July 7 and August 2 at EVSRC, and five times between July 6 and August 14 at SMS. At all locations, fruits were harvested at the 3/4 color development stage of maturity (Table 1), weighed, and graded using the standards of the Sweet Pepper Grader'sGuide (Tables 2 and 3) (Circular ANR-783 of the Alabama Cooperative Extension Service). Yields may have been 10-20% higher had the fruits been harvested at the mature-green stage. At EVSRC, early and total production were similar, because heavy rainfalls in June resulted in water logging, early production decline, and plant death. TABLE Variety 2.

SPRING 1994 COMMERCIAL VEGETABLE VARIETY TRIALS 5 CANTALOUPE VARIETY TRIAL Eric Simonne, Joe Kemble, Jim Pitts, and Kenneth Short On May 6, 13 varieties of orange-fleshed cantaloupes were direct seeded on plastic-mulched beds at the Chilton Area Horticulture Substation in Clanton. Single-row plots were 40 feet long, four feet wide, and contained approximately 10 hills per plot. Banded preplant fertilizer provided 50 pounds of nitrogen (N) per acre, plus 100% of required phosphorus (P) and 75% of required potassium (K) as based on soil test results. Soluble fertilizer was injected weekly through the drip-irrigation system at a rate of six pounds of N per acre alternately from 20-20-20 and potassium nitrate (KNO 3 ) between emergence and last harvest. Throughout the growing season, plants were sprayed approximately every 10 days with Bravo (fungicide) and Lannate (insecticide) each at a rate of two pints in 100 gallons per acre. Cantaloupes were harvested on July 5, 8, 12, and 15 (see table). Soluble solid content, which evaluates sweetness, was determined on two representative cantaloupes of each plot. 1 SEED SOURCE, YIELD AND SOLUBLE SOLIDS FOR CANTALOUPES Variety Seed source Ferry Morse Asgrow Asgrow Asgrow Asgrow Rogers NK Harris Seed Petoseed Asgrow Harris Seed Auburn U.

However, several blockytype bell pepper varieties with unusual colors at maturity are now available. Colored pepper variety trials were conducted at the Piedmont Substation (PS) in Camp Hill, the Sand Mountain Substation (SMS) in Crossville, and the Chilton Area Horticulture Substation (CAHS) in Clanton. Five-week-old peppers were transplanted on June 13 at PS, May 6 at SMS, and May 5 at CAHS. Plots consisted of a single 4x20-foot row. Within-row spacing was one foot, which created a stand of approximately 7,300 plants per acre. At CAHS, black plastic mulch and drip irrigation were used, while at PS and SMS peppers were grown on bare ground. At PS, a 13-13-13 fertilizer was applied preplant at a rate of 600 pounds per acre. Calcium nitrate was sidedressed [20 pounds of nitrogen (N) per acre] on July 5 and 19. Irrigation water was provided through drip tapes as needed. No sprays were necessary. At SMS, preplant fertilizer provided 30 pounds of nitrogen (N) per acre, plus 100% of required phosphorus (P) and 75% of required potassium (K) as based on soil test results. Potassium nitrate (KNO 3 ) TABLE 1. SEED SUPPLIER, FRUIT TYPE, AND COLOR was sidedressed (13 pounds of N per acre) on June 10, July 11, and August 4. Plots were overhead irrigated as needed. At CAHS, preplant fertilizer provided 30 pounds of N per acre, plus 100% of required P and 75% of required K as based on soil test results. Soluble fertilizer was injected weekly at a rate of six pounds of N per acre alternately from 20-20-20 and KNO 3 between emergence and last harvest. Plants were sprayed approximately every 10 days with Bravo (fungicide) and Lannate (insecticide), each at a rate of two pints in 100 gallons per acre. At all locations, fruits were harvested at the 3/4 color development stage of maturity (Table 1), weighed, and graded using the standards of the Sweet Pepper Grader's Guide (Circular ANR-783 of the Alabama Cooperative Extension Service). Plots were harvested six times between June 23 and August 11 at CAHS, three times between August 17 and September 2 at PS, and four times between July 20 and August 2 at SMS. Early production (Table 2) included the first three harvests. Production at SMS and PS was expected to continue until frost, thus total production did not include all harvests at these units (Table 3).

SPRING 1994 COMMERCIAL VEGETABLE VARIETY TRIALS 9 EGGPLANT VARIETY TRIAL Eric Simonne, Jim Bannon, Marlin Hollingsworth, Joe Kemble, and Jimmy Witt Because the demand for eggplant in specialty markets is increasing, the performance of selected eggplant varieties was evaluated at the Horticulture Unit of the E.V. Smith Research Center (EVSRC) in Shorter and the North Alabama Horticulture Substation (NAHS) in Cullman. Five-week-old eggplants were transplanted on three-feet-wide, drip-irrigated beds covered with plastic - on May 10 at EVSRC and on May 11 at NAHS. Within-row spacing was 24 inches, which provided a stand of 3,600 plants per acre. Plastic mulch color was white at NAHS and black at EVSRC. At EVSRC, beds were fumigated with methyl bromide at a rate of 400 pounds per acre eight weeks before transplanting. A combination of 16-0-0, 0-460, and 0-0-60 was preplant broadcast to provide 60 pounds of nitrogen (N), 60 pounds of phosphorus (P), and 60 pounds of potassium (K), per acre. Starting one week after transplanting, five pounds of N were injected weekly through the irrigation system, alternatively from 20-20-20 and potassium nitrate (KNO 3 ). Insect control consisted of applications of Thiodan 3EC (two pints per acre) on May 25, July 9, and August 5; Asana XL (eight ounces per acre) on June 10, July 18 and 28, and September 9; Carbaryl (two quarts per acre) on June 28 and August 22; Ambush (eight ounces per acre) on August 18 and 22 and September 2, 13, and 21; and Lannate LV (three pints per acre) on August 26 and 29 and September 9, 16, and 19. TABLE 1. PLANT Variety AND FRUIT Source Fungicide applications consisted of Benlate 50 WP (one-half pound per acre) on May 25; Bravo 720 (1.5-3 quarts per acre) on June 10, July 9 and 28, and September 9 and 16; Ridomil (two pounds per acre) on July 9, August 5, and September 2 and 13; Dithane (two pounds per acre) on July 18 and August 18; and Manzate (two pounds per acre) on August 11. At NAHS, beds were fumigated with methyl bromide at a rate of 400 pounds per acre on April 28. Preplant application of fertilizer provided 30 pounds of N, 50 pounds of P, and 35 pounds of K. Between May 30 and final harvest, injections of combinations of ammonium nitrate (NH 4 NO 3 ), calcium nitrate [Ca(N0 3) 2 ], and KNO 3 were made weekly through the drip tubes. Per-acre application rates ranged between 10-20 pounds for NH 4 NO 3 , 10 -50 pounds for Ca (NO 3 ) 2 , and 10-90 pounds for KNO 3 . Pest control consisted of applications of Penncap M (insecticide, at a rate of one pint in 50 gallons per acre), Manzate (fungicide, at a rate of three pounds in 50 gallons per acre), and Dimethoate (insecticide, at a rate of one-half pint in 50 gallons per acre) on May 16 and July 6. Plants were also sprayed with Bravo (fungicide, at a rate of 1.5 pint in 50 gallons per acre); Asana (insecticide, at a rate of 9.2 ounces in 50 gallons per acre) on June 27 and July 5, 11, 19, and 25; and Ridomil (fungicide, at a rate of one pound in 50 gallons per acre) on July 5, 11, 19, and 25. Eggplants were harvested nine times between July 5 and August 19 at NAHS and 10 times between June 22 and August 23 at EVSRC.

Plots consisted of a single 42-inch x 20-foot row and within-row spacing was eight inches, which provided a stand of 19,000 plants per acre approximately. Preplant herbicide was Curbit applied on May 23 at a rate of three quarts in 50 gallons per acre. Plants were sprayed with Bravo (fungicide, at a rate of 1.5 pints in 50 gallons per acre); Asana (insecticide, at a rate of 9.2 ounces in 50 gallons per acre) on June 20 and 27 and July 5, 11, and 19; and Ridomil (fungicide, at a rate of one pound in 50 gallons per acre) on July 5, 11, 19, and 25. Fertilization consisted of a preplant application four days before planting of 13-13-13 at a 1,000-pound per acre rate and a sidedress application of 240 pounds per acre of 34-0-0 (NH4 NO 3 ) 30 days after planting. Plots were overhead irrigated immediately after planting. Cucumbers were harvested 10 times between July 5 and July 27. After each harvest, fruits were counted and graded as described in the Cucumber Grader's Guide (Circular ANR-771 from the Alabama Cooperative Extension Service).

Smith Research Center (EVSRC) in Shorter, and the North Alabama Horticulture Substation (NAHS) in Cullman. Plots consisted of 15-feet-long rows spaced 30 inches apart. Within-row spacing was approximately four inches. At WS, a 6-20-20 fertilizer was preplant applied at rate of 500 pounds per acre on May 2. Treflan (herbicide) was preplant applied on May 3 at a rate of one pint per acre. Planting date was May 5. Plants were sprayed with Thiodan (insecticide) at a rate of 1.5 pints per acre on June 21 and 28. Plots were cultivated on July 2 and 22. Abundant rainfall and overhead irrigation supplied at least one inch of water per week. At EVSRC, following soil testing recommendation, 30 pounds of N per acre were preplant applied. Planting date was May 13. Plots were overhead irrigated as needed. Treflan (herbicide) was applied on May 12 at a rate of one pint per acre. Insect control consisted of applications of Thiodan 3EC (at a rate of 2.5 pints per acre) on July 9 and August 5, Asana XL (at a rate of eight ounces per acre) on July 18, and of Carbaryl (at a rate of two quarts per acre) on June 28 and July 28. Fungicide applications consisted of Bravo 81W (at a rate of two pounds per acre) on June 28 and Ridomil (at a rate of two pounds per acre) on June 28 and July 9. At NAHS, following soil testing recommendation, a 5-10-15 fertilizer was preplant applied at a rate of 250 pounds per acre. Planting date was July 7. Pest control consisted of a preplant application on July 7 of Di-syston 15G (insecticide) at a rate of 10 pounds per acre. Dual (herbicide) was applied on July 7 at a rate of 1.5 pints per acre. Due to abundant rainfall, no overhead irrigation was needed. To simulate once-over harvesting used by commercial processors, plots were individually harvested when 80% of the pods became dry. Actual harvest dates were between July 13 and Aug. 2 at WS, July 27 and August 23 at EVSRC, and Sept. 13 and 27 at NAHS. Total weight and shelled weight were determined. However, due to differences in dryness, imbibed weights were reported (see table). Imbibed weights were determined by weighing all the shelled peas after they were soaked in water to allow the dry seeds to absorb water (imbibe) and reach similar water content as the green seeds.

IM... n lP I.fII I SUMMER SQUASH VARIETY TRIAL Eric Simonne, Brian Gamble, Marlin Hollingsworth, Henry Ivey, Joe Kemble, Jim Pitts, Kenneth Short, and Larry Wells Squash variety trials were conducted at the Chilton Area Horticulture Substation (CAHS) in Clanton, the North Alabama Horticulture Substation (NAHS) in Cullman, and the Wiregrass Substation (WS) in Headland. Yellow summer squash (straightneck or crookneck) have traditionally been grown in Alabama. However, since the demand for zucchini squash has been increasing, varieties of zucchini squash also were evaluated. At the three locations, squash were direct seeded at a one-inch depth in single-row 5x20-foot plots. In-row spacing was 18 inches, which provided a stand of 6,000 plants per acre, approximately. At CAHS, the field was drip irrigated, and the beds were covered with black-plastic mulch. Trials at NAHS and WS were conducted on bare ground. At CAHS, planting date was early May. Preplant fertilizer was banded and provided 30 pounds of nitrogen (N) per acre, plus 100% of required phosphorus (P) and 75% of required potassium (K) as based on soil test results. Soluble fertilizer was injected weekly at a rate of six pounds of N per acre alternately from 20-20-20 and potassium nitrate (KNO 3 ) between emergence and last harvest. Plants were sprayed approximately every 10 days with Bravo (fungicide) and Lannate (insecticide), each at a rate of two pints in 100 gallons per acre. At NAHS, planting date was May 23, and the field was overhead irrigated the next day. Fertilization consisted of a preplant application four days before planting of 13-13-13 at a rate of 1,000 pounds per acre. Thirty days after planting, ammonium nitrate (NH 4 NO 3 ) was sidedressed at a rate of 250 pounds per acre. Preplant herbicide was Curbit applied on May 23 at a rate of three quarts in 50 gallons per acre. On June 27 and July 5, 11, 19, and 25, plants were sprayed with Bravo (fungicide, at a rate of 1.5 pint in 50 gallons per acre) and Asana (insecticide, at a rate of 9.2 ounces in 50 gallons per acre). Ridomil (fungicide, at a rate one pound in 50 gallons per acre) was applied on July 5, 11, 19, and 25. At WS, squash were planted on April 21. Preplant fertilizer consisted of (per acre) 30 pounds of N, 100 pounds of P, and 100 pounds of K and was applied broadcast on April 20. Squash were sidedressed with KNO 3 at a rate (per acre) of 50 pounds of N 28 days after planting and 40 pounds of N 43 days after planting. Due to abundant rainfall, overhead irrigation was applied only on May 25. Sonalan, a pre-emergence herbicide, was applied at a one-quart per acre rate. Plants were sprayed with Bravo (fungicide, at a one-quart per acre rate) on May 20 and 27. Frequent harvests are needed for the squash to remain "fairly young and fairly tender," which are necessary characteristics for squash to be graded as US #1. Hence, fruits were harvested 14 times at CAHS between June 10 and July 14, 10 times at NAHS between June 30 and July 29, and eight times at WS between May 30 and June 24. Excessive rainfall occurred in the Wiregrass area during the month of June, resulting in excessive moisture, possible nutrient leach, water logging, and reduced yields. At harvest, fruits were graded as US #1, US #2, or cull according to the United States Standards for Grades of Summer Squash (U.S. Department of Agriculture G.P.O. 1987-180-916:40730 AMS). Marketable yield was calculated by adding the US #1 and US #2 yields. Earliness (Table 1) was evaluated by combining the yields of the first four harvests. Total production (Table 2) was also determined. SPRING 1994 COMMERCIAL VEGETABLE VARIETY TRIALS 15 TABLE 1.

Five-week-old tomatoes were transplanted on May 11 at NAHS and on May 6 at SMS onto threefeet-wide, trickle-irrigated beds covered with plastic. The plastic color was white at NAHS and black at SMS. At both locations, plots were 4x 12 feet. Withinrow spacing was 18 inches, which created an approximate stand of 5,800 plants per acre. At NAHS, beds were fumigated with methyl bromide at a rate of 400 pounds per acre on April 28. A preplant application of 600 pounds per acre of a 1313-13 fertilizer provided 80 pounds of nitrogen (N), 35 pounds of phosphorus (P), and 65 pounds of potassium (K). Between May 30 and final harvest, injections of combinations of ammonium nitrate (NH 4 NO 3 ), calcium nitrate [Ca(NO 3 )2 ], and potassium nitrate (KNO 3 ) were made weekly through the drip tubes. Application rates ranged between 10-20 pounds per acre for NH 4 NO 3 , 10-50 pounds per acre for Ca(NO 3 ) 2 , and 10-90 pounds per acre for KNO 3 . Preplant herbicide was Lexone DF applied on May 20 at a rate of 1.5 pounds per acre. Insect control consisted of an application of Pencarp M (at a rate of one quart in 50 gallons per acre), Manzate 200 (at a rate of two pounds per 50 gallons per acre), and Dimethoate (at a rate of one-half pint in 50 gallons per acre) on May 30 and June 6. Plants were also sprayed with Bravo (fungicide, at a rate of 1.5 pint in 50 gallons per acre) and Asana (insecticide, at a rate of 9.2 ounces in 50 gallons per acre) on June 20 and 27 and July 1,5, and 11; and Ridomil (fungicide, at a rate of one pound in 50 gallons per acre) on July 1, 5, and 11. At SMS, plots were fumigated with methyl bromide at a rate of 300 pounds per acre two weeks before transplanting. Preplant fertilizer incorporated on April 27 provided (per acre) 75 pounds of N, 60 pounds of P, and 60 pounds of K. Between June 14 and August 20, weekly fertilizer application consisted of alternate injections of 20-20-20 and KNO 3 at a rate of 10 pounds of N per acre. Weeds were controlled with an application of Poast (1%) on June 1. Other sprays included applications of Sevin at a rate of 1.25 pounds per acre and Bravo at a rate of two pints per acre on June 29, and of applications of Ridomil at a one-pound per acre rate and Sevin at a rate of 1.25 pounds per acre on July 15. Plots were harvested six times between July 19 and August 8 at NAHS, while at SMS seven harvests were done between July 8 and August 19. At both locations, fruits were harvested at the breaking stage, weighed, and graded. Grades and corresponding fruit diameters (D) were adapted from the Tomato Grader's Guide (Circular ANR 643 from the Alabama Cooperative Extension Service). These grades were Jumbo (D> 3.5 inches), Extra-Large (D> 2.9 inches), Large (D> 2.5 inches), Medium (D> 2.3 inches) and Small (others). Early production was determined by adding the yields of the first three harvests (Table 1). Marketable yield was calculated by combining the Jumbo, Extra-Large, and Large grades (Table 2). 21) ALARAMA Ar..Rlr.111 TIIPAI FYPFRIKAFNT -QTATIr)MI TABLE1 TOMATO EARLY PRODUCTION AND GRADEDISTRIBUTION Variety Source Market. wt.'

Watermelons were direct-seeded on bare ground in 5x60-foot plots with a hill spacing of approximately 10 feet. Planting dates were March 31 at GCS, May 23 at NAHS, and May 20 at SMS. At GCS, fertilization consisted of a preplant broadcast application of a 4-12-12 fertilizer at a rate of 500 pounds per acre on March 18, followed by two sidedress applications on April 25 and May 5 of 15-014 at a rate of 200 pounds per acre. Plants were irrigated as needed. Weed control consisted of broadcast application of a pre-emergence herbicides (Alanap) on April 4 at a rate of six quarts per acre and Poast (with two pints of Oil Concentrate per acre) on April 26 at a rate of 1.5 pints per acre. An application of Manzate (fungicide) was made on May 11, and Bravo 720 (fungicide) was used on May 25, June 8, and 21 at a rate of three pints per acre. At NAHS, a 13-13-13 fertilizer was preplant incorporated at a rate of 500 pounds per acre on May 19. Plants were sidedressed 40 days after planting with 220 pounds of ammonium nitrate (NH 4 NO 3 ). Preplant herbicide was Curbit applied on May 19 at a rate of three quarts in 50 gallons per acre. Pest control consisted of applications of Bravo (fungicide, at a rate of 1.5 pint in 50 gallons per acre) and Asana (insecticide, at a rate of 10 ounces in 50 gallons per acre) on June 20 and 27. On July 1, herbicides (Post at a rate of one pint in 50 gallons per acre and Crop Oil at a rate of one quart in 50 gallons per acre) were applied. At SMS, preplant fertilizer provided (per acre) 60 pounds of nitrogen (N), 60 pounds of phosphorus (P), and 100 pounds of potassium (K). The plants received a sidedress application of potassium nitrate (KNO 3 ) at a rate of 220 per acre 38 days after planting. An application of Post (1.5% solution) was made on July 12. Repeated rainfall interfered with the normal spray schedule. Watermelons were harvested on June 29 and July 5 and 11 at GCS, August 23 at NAHS, and August 22 at SMS. Important characteristics for watermelons are marketable yield, sweetness, and rind thickness. Fruits were graded as described in the Watermelon Grader'sGuide (Circular ANR 681 from the Alabama Cooperative Extension Service) and marketable yield was determined. Two representative melons were selected from each plot for the measure of soluble solids, which is used to evaluate sweetness (Table 1). Watermelons with soluble solid levels of less than 100 Brix do not taste very sweet. Rind thickness is used as an indicator of shipping ability and resistance to bruising and splitting during handling. In the selected varieties, rind thickness ranged between 0.5-1 inch.
