General Cultural Practices

These watermelon studies were grown on black plastic mulch and fertigated with drip tube. Pesticides used on all plots were chemicals labeled for that crop, (2019 North Carolina Agricultural Chemicals Manual).

Watermelon Cultural Practices for 2019 Cultigen Studies, Horticultural Crops Research Station, Clinton, NC

Introduction

Growing conditions for the 2019 watermelon crop were generally very favorable throughout the season. North Carolina showed a modest increase in watermelon production from 2017 to 2018.

In 2017 acreage was reported at 6,300 acres and in 2018 acreage was reported at 6,700. North Carolina ranks 7th among watermelon producing states and represents 6 % of the U.S. acreage which totaled 115,800 acres in 2018. This translates into an economic value of $21 million to North Carolina. The average fruit sizes for the 2019 watermelon crop were not as large as they were in 2018; however, overall fruit sizes were still slightly above average throughout the 2019 growing season (P. Westerbeek, personal communication). Recent reports indicate that standard size watermelon (wholes) still account for 80 % of the US market followed by mini-watermelon (10 %) and cut watermelon (10 %).

Materials and Methods

Once all seeds were received from participating companies, they were planted into 72 cell Poly trays to grow transplants (Hummert Int.; Earth City, MO). Seeds of standard and mini size cultigens were sown on 4 April 2019 and 2 April 2019, respectively. The planting medium used was “fine germinating mix”, a commercial soilless mix (SunGro, Agawam, MA). Approximately 3 weeks after seeding, transplants were placed in a “hardening” greenhouse for approximately one week before being transplanted in the field. Telone II (12 gal/ac) was applied to the entire study area on 25 April 2019. K-Mag fertilizer (0-0-22-22S-11Mg) was applied pre-plant at a broadcast equivalent rate of 160 lbs/ac on 29 March. On 12 April the following pre-plant fertilizers were also applied to the entire study area (1.74 ac) in a broadcast equivalent rate of: (0-0-50) at 250lbs./ac; (15.5-0-0) at 200 lbs./ac and (18-46-0) at 100 lbs./ac. Black polyethylene plastic (1.25 mil thick high density plastic film, 60 inches wide; B.B. Hobbs, Clinton, NC) was laid on 25 April 2019. Standard and mini size triploid plants were established in the field on 13 May and 10 May 2019, respectively. Plot size for standard triploid size watermelons was 1 row, 10 plants per plot, 25 feet long with alleys of 10 feet between plots. In most cases, plots with missing plants were replanted approximately 3 days after planting to achieve 100% plant stand. ‘‘SP-7’’ and ‘‘Wild Card Plus’’ diploid pollinizer plants were used in the 2019 growing season. Alternate plantings of ‘‘SP-7’’ and ‘Wild Card Plus’ (4 plants/plot) were used as the pollinizer plants in each plot within the study. ‘SP-7’ pollenizer plants were planted after triploid plants 1 and 7 while ‘Wild Card Plus’ pollinizer plants were planted after triploid plant 4 and 10 in each plot. Row middles were 10 feet for all watermelon types and in-row spacing was 2.5 feet for the standard size triploid watermelons. Drip tape (NETAFIM, 12 inch spacing, 0.24 gph; NETAFIM, Tel Aviv, Israel) was installed beneath the plastic mulch and was utilized to fertigate the crop throughout the growing season. The following herbicides were applied to row middles on 8 May 2019; Sandea (1 oz/ac) and Strategy (4pt/ac). A subsequent application of Gramoxone (1qt/ac) plus crop oil (1 qt/ac) was spot sprayed on weed escapes on 22 May 2019.

Insecticides Carbaryl (1 qt/ac) and Asana (8 oz/ac) were rotated and applied as a preventive measure on the following dates; 23 and 31 May 2019; 14, 21 and 27 June 2019; 3, 10 and 26 July 2019. Insecticide products were sprayed in rotation to avoid potential development of insect resistance.

Miticides Abba Ultra (8 oz/ac), Bantar (1lb/ac) and Portal (1 qt/ac) were rotated and applied on the following dates; 21 and 27 June 2019; 10 July 2019. These miticide products were rotated to avoid potential development of mite resistance to these products.

A total of 49 lbs/ac N, 46 lbs/ac P and 160 lbs/ac K were all applied broadcast (pre-plant) to the entire study area. Liquid fertilizer with 4-0-8 analysis was initially applied through drip tape fertigation on 21 May 2019 and similarly on the following dates; 22, 28 and 31 May 2019; 3, 4, 6, 12, 14, 17, 18, 19, 20, 24, 25 and 27 June 2019; 1, 8 and 10 July 2019.  A total of 71 lbs/ac N, 0 lbs/ac P and  141 lbs/ac K were applied via fertigation throughout the growing season. Cumulative totals of applied fertilizer for the growing season were: 120 lbs/ac N, 46 lbs/ac P, 301 lbs/ac K, 20 lbs/ac S and 10 lbs/ac Mg.

Fungicides were initially applied on 31 May 2019 and similarly on the following dates: 14, 21 and 27 June 2019; 3, 10 July 2019. The following fungicides were rotated to avoid potential development of resistance from diseases; Bravo (1 qt/ac), Cabrio (16 oz/ac), Copper (1 lb/ac), Inspire (1pt/ac), Manzate (3 lb/ac), Presidio (4 oz/ac), Pristine (1 lb/ac), Quadris (14 oz/ac) and Tanos (8 oz/ac). Insect and disease pressure was minimal throughout the season with the exception of a flare up of spider mites that did moderate damage to watermelon vines in the entire study just prior to first harvest. The labeled rate of Abba Ultra, Portal and Bantar was applied for mite control. Significant crop vine loss occurred due to mites that resulted in significant sun scald on many fruit in the study. Each fruit was harvested when ripe, weighed and categorized statistically by size category.

Standard size triploid watermelon harvests (3) took place on: 17, 25 and 31 July 2019. For the triploid standard size watermelon test, fruits were placed in the following categories: ≤ 9.0 lbs, 9.1 – 13.5 lbs, 13.6 – 17.5 lbs, 17.6 – 21.4 lbs, and ≥ 21.5 lbs. Fruits were considered marketable if they weighed 9.1 lbs or more. Fruit are often commercially marketed by number or count per bin with 9.1-13.5 lbs fruit termed 60-count, 13.6 – 17.5 lbs fruit termed 45 count, 17.6 – 21.4 lbs fruit termed 36-count, and fruit 21.5 lbs or larger termed 30-count. We used these weight designations to categorize the harvested fruits in this study. The most popular standard triploid fruit size has typically ranged from 12-16 lbs and the majority of fruit harvested in this study ranged between 9.1 and 13.5 lbs. The mini triploid watermelon transplants were established in the field on 10 May 2019. Plot size for mini triploid size watermelons was 1 row, 8 plants per plot, 15 feet long with alleys of 10 feet between plots. Alternate plantings of ‘SP-7’ and ‘Wild Card Plus’ (4 plants/plot) were used as the pollenizer plants in this study. ‘SP-7’ pollenizer plants were planted after triploid plants 1 and 5 while ‘Wild Card Plus’ pollenizer plants were planted after triploid plant 3 and 7. Row middles were 10 feet for all watermelon types and in-row spacing was 1.9 feet for the mini size triploid watermelons. 

Mini triploid watermelon harvests (3) occurred on: 17 and 25 July 2019; 5 August 2019. For the mini triploid watermelon test, fruits were placed in the following categories: ≤ 3.0 lbs, 3.1 – 7.0 lbs, 7.1 – 9.0 lbs, and ≥ 9.1 lbs. Evaluations of each watermelon entry included yields, fruit size, production earliness, soluble solids, using a hand held digital refractometer (Atago, Vernon Hills, IL), 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 the USDA standards. Fruits were cut longitudinally in half, and then these halves were cut laterally. The number of hard seeds exposed on the cut surface were counted and recorded.

This is the sixth year we have rated for hard seeds according to the USDA standards. Evaluations of each melon entry included; yield, fruit size, production earliness, soluble solids, fruit shape and size and interior flesh firmness. Flesh firmness was taken by using a Penetrometer FT 011 with a 7/16” plunger tip, (QA Supplies LLC, Norfolk, Va.), and recorded in pounds. Soluble solids were measured by cutting a piece of fruit from the center of the fruit and squeezing out the fruit juice onto the digital refractometer (Atago, Vernon Hills, IL). 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 areas and are an average value taken for five fruit per plot or 20 fruits per cultigen. Most of the quality measurements were taken at the first or second harvests.
