Introduction

The acreage for melon production in North Carolina has not been published, however, it is estimated that 3,000 to 4,000 acres are produced in the state. In 2017 a survey of US growers estimated orange flesh melon production was 58,000 acres (USDA, National Agriculture Statistics Service). Since 2013, the US orange flesh melon crop has seen significant decreases in acreage (2013, 74,000 acres valued at 319 million) to 2017 when US acreage was reported to be 58,000 with a total crop value of 267 million. Further reporting showed domestic orange flesh melon prices have steadily declined from their peak of 0.25/lb in 1980 to a season-average of 0.18/lb in 2013. The majority of melons grown in North Carolina are eastern type with ‘Athena’ being the principle cultivar produced for more than two decades. In addition to the eastern shipper type orange flesh melon, other orange flesh melons are being grown on much smaller acreage include Extended Shelf Life (ESL); Long Shelf Life (LSL) melons, often termed Harper melons; and a third type termed Italian (Tuscan) melons. The ESL or LSL melons, as the name suggests, will hold for a longer period than the eastern type melons. Flesh firmness and sweetness tend to be higher in the ESL or LSL type melons. Greater flesh firmness allows the fruit to hold up better over time. This trait increases the shipability, a term often referred to as giving the fruit ‘better legs’. It can be more difficult to determine readiness on LSL melons and this has delayed willingness from growers in part to move into larger scale production of these melons. More recently, the release of new cultigens with ESL traits have performed well for growers and have received favorable support from consumers. Two such examples would be ‘Accolade’ and ‘Astound’ that were released by Syngenta in 2016. It is reported that these new cultivars comprise as much as 30% of the market, taking some market share from ‘Athena’. The Italian (Tuscan) type melons tend to split easier than the ESL/LSL or Eastern types and more intense management of the crop harvest may be necessary in order to minimize fruit loss due to splitting. In spite of these challenges with ESL/LSL and Italian (Tuscan) type melons, North Carolina growers have had some success in producing and marketing these newer melon types. In 2018 several new cultigens were evaluated in our melon field study and we had a total of 24 advanced lines or cultivar entries (cultigens) from 7 seed companies and 1 University. All entries were evaluated for yields, earliness, and various other qualities.

Materials and Methods

In February and March commercial seed companies were contacted to obtain seed for the orange flesh melon cultigen evaluation study. Seed were sown into 72 cell Poly trays to grow transplants (Hummert Int.; Earth City, MO) on 13 April 2018. The planting medium used was a Fine Germinating Mix, a commercial soilless mix (SunGro, Agawam, MA). In November 2017 the field study area (0.28 acre) was fumigated with Telone 17 and a cover crop was established. On 23 March 2018 the field study area was plowed using a disc harrow and then cultivated on 27 March.

A complete fertilizer (12-6-24 @ 400 lbs/ac) was broadcast applied and black polyethylene plastic mulch (0.70 mil thick high density plastic film, 48 inches wide; B.B. Hobbs, Clinton, NC) was laid in the field on 23 March.
Herbicide products, Prefar (5 qt/ac), Sonolan (4 pt/ac) and Honcho Plus (2 pt/ac) were applied to row middles for pre-emergent weed control on 4 May. Orange flesh melon transplants were approximately 3 weeks old when placed in a “hardening” greenhouse for 7 days prior to being established in the field on 21 May. A starter fertilizer was applied at transplant (0.5 lb of 20-20-20, water soluble fertilizer/50 gal H2O).

Plot size was one row with 10 plants per plot (20 ft) with in-row spacing of 2 feet and between-row spacing of 5 feet. Field arrangement for the orange flesh melon cultigen study was a Randomized Complete Block Design (RCBD) with four replications. Plots that were missing plants were replanted approximately 7 days after transplanting to achieve 100% stand, in most cases. Drip irrigation was utilized (NETAFIM, 12 inch spacing, 0.24 gal/hr; NETAFIM, Tel Aviv, Israel) throughout the growing season. Fertigation with 7-0-7 liquid fertilizer was initiated 9 days after planting and applied weekly, thereafter. The first application of liquid fertilizer (2.5 gal) was applied through the drip tube on 30 May and the last application (3.5 gal) was applied 1 August. Fertilizer was applied either preplant or through fertigation in this study. Total amount of fertilizer applied through fertigation for the season was 39 lbs/ac of N and 39 lbs/ac of K²O. The total amount of fertilizer applied for the entire growing season was 87 lbs/ac of N, 24 lbs/ac of P²O5 and 135 lbs/ac of K²O.

Insecticides were applied as needed throughout the growing season beginning 31 May and followed by subsequent applications on 6, 13, 20 and 27 June; 3, 18 and 25 July 2018. The following insecticide products were alternated throughout the season to avoid potential resistance development in insect species; Asana, Assail, Endosulfan, and FanFare. Similarly, the following fungicide products were applied; Presidio, Pristine, Proline, Procure, Quadris, Ranman, Switch and Zampro; and applied on the following dates; 31 May; 6, 13, 20 and 27 June; 3, 18 and 25 July;
and 7 August 2018.

There were 12 total harvests of the orange flesh melon cultigens. The first harvest was 9 July 2018 and the twelfth harvest was 3 August 2018. Harvests occurred three times per week on Monday, Wednesday and Friday.
Evaluations of each melon entry included; yield, fruit size, production earliness, soluble solids (using a digital refractometer, Atago, Vernon Hills, IL), fruit shape and size and interior flesh firmness. Flesh firmness was measured (recorded in pounds) by using a Penetrometer FT 011 with a 5/16” plunger tip, (QA Supplies LLC, Norfolk, VA). Melon samples were obtained by cutting through the ground spot of the fruit, lengthwise, from the fruit’s stem end to blossom end. Flesh firmness (measured in pressure) measurements were taken between the interior fruit cavity and the rind (near fruit bottom or ground spot and one from the top of the fruit) on one-half of the cut fruit. The reported measures on flesh firmness are an average of the two sample areas from five fruit per plot (10 total fruit firmness measures were obtained per plot). The majority of quality measurements were taken when the melons became ripe between the first and fourth harvests for a given cultigen.

The field and growing conditions throughout the harvest period were normal for this study. Rainfall for the season was above average rainfall throughout the season. Optimal ambient temperatures that allowed for good plant growth and fruit set within all the cultigen plots. This study was established in the field nearly 3 weeks later than in 2017; however, the crop grew off quickly with fruit harvests nearly coinciding to the previous year.
Six entries included in the study were submitted from Texas A&M. Those cultigens were Davinci, F39, HD150, HD252, Infinite Gold and OC164. Fruits from these cultigens were shipped to Texas and Arizona to be evaluated as part of a food safety and soil borne pathogen evaluation study. HD150 and HD252 are honeydew melons, OC164 is an orange casaba melon, while the other 3 entries are orange flesh melons.

Results

In the early harvests (1-4), entries that yielded over 200 cwt per acre were Athena, Master’s Choice, Napoli, and Oui (Table 1). The highest yielding entries based on fruit numbers that exceeded 4,000 fruit per acre for early harvests
(1-4) were Athena, HMX4606, Master’s Choice, Napoli, Oui, SVML2502, USAM 14836 (Table 2). The 3 to 7 lb. size category had the highest percentage of fruit produced from the early yielding entries with the exception of SVML2690 that produced fruits that were ≤ 3 pounds. Fruits ranging from 3 to 7 pounds are the most desirable and marketable size category for orange flesh melons (Tables 3 & 4) in eastern US markets.

The highest yielding entries for fruit weight, in the mid-season harvests (5-8), that yielded over 400 cwt per acre were OC164 and USAM 16141 (Table 5). The entries that yielded the highest (> 6,000 fruit number) in the mid- season (harvests 5-8) were Davinci, Infinite Gold, SVML2690 and USAM 14837 (Table 6). Most fruits produced from these entries were between 3 to 7 lbs., with the exception of SVML2690 which produced fruits ≤ 3 lbs. (Tables 7 & 8). Fruits that weigh ≤ 3 lb. category would ordinarily be culled in eastern US markets other markets, however, other markets in the US sell smaller sized fruits.

Some of the latest yielding (harvests 9-13) melon entries that exceeded 100 cwt per acre were El Gordo, F39, HD150, and HD252 (Table 9). Average fruit size for these entries were 13.7, 4.0, 5.5, and 5.6 lbs, respectively. (Table 9). El Gordo, OC164 and USAM 16155 yielded fruits that weighed mostly above 7.1 lbs. (Table 11).

The highest yielding entries across all harvests, in terms of tonnage (> 450 cwt/acre) were El Gordo, Electra, HD252, Lily, Master’s Choice, OC164, USAM 16141 and USAM 16155 (Table 13). The melon entries that produced the greatest number of fruit per acre (> 9,000) across all harvests were DaVinci, Electra, Infinite Gold, Master’s Choice, Oui, F39, SVML2502, SVML2690, and USAM 14836 (Table 14).
