Horticulture Series # 210

Principle Investigators: Jonathan R. Schultheis, Professor and Vegetable Extension Specialist and W. Bradfred Thompson, Research Specialist, Department of Horticultural Science, NC State University, Raleigh, NC

General Cultural Practices

The watermelon trials were grown on black plastic mulch and fertigated with drip tube. Pesticides used on all plots were chemicals labeled for that crop, (2014 North Carolina Agricultural Chemicals Manual)

Introduction

Watermelon continues to be an important crop grown in North Carolina as the state was ranked seventh in production among U.S. states nationally in 2012 representing 6.4% of the nation’s watermelon production. Approximately 8,300 acres valued at nearly $34.9 million were produced and harvested in North Carolina in 2012. Growers in NC need to remain competitive in the market place and must grow and sell the best cultivars. More recently, in addition to yields, seed companies and markets have focused on specific traits such as lycopene and citrulline content, hollow heart incidence, seed trace size, and flesh firmness. We have committed more of our resources to the evaluation of many of these traits. In the tables that follow, the adaptability of the various red-flesh watermelons is evaluated, both for yields and quality. This should help the watermelon industry make informed decisions regarding newly released red-flesh cultivars or those that are being considered for release.

Materials and Methods

We have evaluated red-flesh standard size watermelon types annually since 1989. We initiated the evaluation of mini triploid watermelon types in 2003. Before the growing season, companies which sell watermelon seeds were contacted to obtain seed for the watermelon cultivar trials.

Once all seed were obtained, they were planted into Poly growing transplant trays (Hummert Int.; Earth City, MO). Seeds of standard size and mini triploid cultigens were sown on 15 April, 2014. The planting medium used was Fine Germinating Mix, a commercial soilless mix (CarolinaGreenhouse and Soil Company; Kinston, NC). Approximately 3 weeks after seeding, the plants were placed in a “hardening” greenhouse and hardened before being established in the field. Standard size triploids and mini triploids were established in the field on 19 May 2014. Fertilizer, 30lb/acre N and 80lb/acre K2O, was incorporated into the beds on 29 April prior to the laying of black polyethylene plastic (0.70mil thick high density plastic film, 48 inches wide; B.B. Hobbs, Clinton, NC). Fumigant (TeloneC-17) was broadcast and incorporated into the soil on 7 November 2013 at 9.0 gallons/acre prior to the start of the growing season. Herbicides, Curbit at 4 pints/acre, Gramaxone at 3 pints/acre, and Prefar at 5 quarts/acre, were applied between the plastic beds for weed control on 29 May. Spacing between row middles was 10 feet for all watermelon types and in-row spacing was 2.5 feet for standard size triploid watermelons and 1 foot for mini triploid watermelons. Plot size for standard triploid size watermelons was one row, 10 plants per plot, 25 feet long with 10 feet alleys between plots. Plot size for the mini triploid watermelons was one row, 10 plants per plot, 10 feet long with 10 feet alleys between plots. At time of transplant, a starter solution was applied using 20-20-20 (0.5 lb/50 gallons water) and 5 oz. Coragen per 50 gallons water for insect control. Plots with missing plants were replanted approximately 7 days after planting to achieve 100% stand in most cases. For the 2014 growing season, ‘SP-6’ was the sole pollinizer source. Pollinizers were interplanted between plants 1 and 2; 5 and 6; and 9 and 10. Trickle irrigation was utilized (NETAFIM, 12 inch spacing, 0.24 gph; NETAFIM, Tel Aviv, Israel) over the growing season. Fertigation was initiated two weeks after planting and applied weekly during the planting season. A total of 61.2lb/acre N and 122.3 lb/acre K2O was drip applied through the season using a 4-0-8 liquid fertilizer. Cumulative amount of fertilizer applied for the season was 91.2 ,0, and 202.3 lb/acre of N, P2O5, and K2O, respectively. Insecticides were applied every week as a preventative measure beginning 4 June and on the following dates (11, 18, and 25 June; 2, 9,16, and 28 July; and 6 and 14 August).The following products were alternated during consecutive spray applications to avoid insect resistance: Asana, Fan Fare, Perm Up, and Sevin. Fungicides were similarly applied throughout the growing season at weekly intervals. The fungicide program that was implemented consisted of the following fungicide products which were alternated during consecutive spray applications to avoid disease resistance: Bravo, Kocide, Pristine, Previcur Flex, Penncozeb, and Ranman; and applied on the following dates; 11, 18, and 25 June; 2, 9, 16, and 28 July; and 6 and 14 August.

There were four harvests for the standard size triploid watermelon study and 5 harvests for the mini triploid watermelon study.The first harvest for the standard size triploid test was 24 July. Subsequent harvests were 30 July; 13 and 20 August.The first harvest for the mini triploid trial was 15 July, and subsequent harvests were 22 and 29 July; and 5 and 13 August. Each fruit was harvested when ripe, weighed and categorized statistically by size category. For the triploid watermelon test, fruits were placed in the following categories; < 8.9 lb, 9.0-13.5lb, 13.6-17.5lb, 17.6-21.4lb, and 21.5+ lb. Fruits were considered marketable if they weighed at least 9 pounds. Fruit are often commercially marketed by number or count per bin with 9-13.5 lb. fruit termed 60-count, 13.6-17.5 lb. fruit termed 45-count, 17.6-21.4 lb. fruit termed 36-count, and fruit 21.5 lb. or larger termed 30-count. We use these weight designations to categorize the fruits harvested in this study. The most popular standard triploid fruit size has typically ranged from 12-16 lb. For the mini triploid trial, fruits were placed into the following categories; < 3lb, 3.0-3.9 lb, 4-7 lb, 7.1 –8.0 lb, 8.1 –9.0 lb, 9.1 –10 lb, and > 10 lb. Fruits were considered marketable if they were within the 3 –7 lb category. Evaluations of each watermelon entry included yield, fruit size, production earliness, soluble solids using a hand held digital refractometer, fruit shape and size, exterior and interior descriptions (rind pattern, length/width ratio, seed trace size, occurrence of hard seeds, hollow heart incidence and severity, and flesh color), and interior flesh firmness. Hard seed in triploid fruit was determined according to USDA standards. Fruits were cut longitudinally in half, then these halves were cut laterally. The number of hard seeds exposed on the cut surface were counted and recorded. This is the second year we have rated for hard seeds according to USDA standards. Flesh firmness was taken by using a Penetrometer FT 011 witha 7/16” plunger tip, (QA Supplies LLC, Norfolk, Va.), and recorded in pounds. Samples were obtained by cutting the center of the fruit from the stem to blossom end. Pressure was then taken in five areas of the fruit; stem end, top side, ground spot side, blossom end, and center. Pressure was not taken on fruit with hollow heart. The reported measures on flesh firmness are an average of the five sample areasand are an average value taken for five fruit per plotor 20 fruit per cultigen. Most of the quality measurements were taken at the first or second harvests.

2014 Trial Note: The 2014 growing season was optimal for watermelon production. Vine growth and fruit set were excellent as wasfruit quality among a majority of the cultivars evaluated. Unlike 2013, there was no crow damage observed within the trial which we attribute to vigorous vine growth that allowed the fruit to size and mature under the cover of the foliage. Overall, we would rate the 2014 trial as one of the best watermelon trials resulting in high yields and fruit quality.

1 Most measurements were obtained from fruits in harvest 1.
2 Rind Thickness=Rinds were measured in 2 regions of the fruit (on one side and directly opposite on the other side) and an average was taken for 5 fruits per replication (20 total).
3 SS = Soluble solids indicates sweetness, average of 5 melons per replication (20 total).
4 Flesh Color Rating: 3=red, 3.5=bright red, 4=dark red, 5=blood red.
5 Fruit pressure was taken by a penetrometer, Fruit Pressure Tester – FT011 from QA Supplies LLC, Norfolk Va. Five melons per replicate, per cultivar, were probed 1/2 the distance between the rind and the center of the melon on the top and bottom sides of each fruit.
