Watermelon Cultural Practices for 2018 Cultigen Studies at the Horticultural Crops Research Station in Clinton, NC

Introduction

Growing conditions for the 2018 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 # 8 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. On average, watermelon fruit were significantly larger in the 2018 crop leading to greater supply of 30 and 36 count size categories and lesser availability of smaller (60 count) watermelon throughout the 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 20 April 2018. 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 about one week before being established in the field. Standard and mini size triploid plants were established in the field on 23 May 2018. On 12 March 2018 a pre-plant fertilizer was applied in the study area at the following rates: 34-0-0 (150 lbs/ac), 0-0-50 (300 lbs/ac) and 0-0-22 (150 lbs/ac). Based on the soil test the study location was low in sulfur, thus, the 0-0-22 that contained sulfur was applied at a rate that would increase sulfur by 12 lbs/ac. The study area was fumigated with Pic-Clor 60 at a rate of 260 lbs/acre at the same time as black polyethylene plastic (1.25 mil thick high density plastic film, 60 inches wide;B.B. Hobbs, Clinton, NC) was laid in field on 23 April 2018. Plot size for standard triploid size watermelons was 1 row, 10 plants per plot, plot length was 25 feet and 10 foot alleys between plots. In most cases, plots with missing plants were replanted approximately 8 days after planting to achieve 100% plant stand. In-row diploid pollinizer plants were ‘SP-7’ (4 plants/plot) in the 2018 growing season. Row middles were 10 feet for all watermelon types and in-row spacing was2.5 feet for the standard size triploid watermelons. Drip tape (NETAFIM, 12 inch spacing, 0.24 gph; NETAFIM, Tel Aviv, Israel) was installed underneath the plastic mulch and was utilized to fertigate the crop throughout the growing season. The following herbicides were applied to row middles on 22 May 2018; Gramoxone (1 qt/ac), Sandea (0.75 oz/ac) and Strategy (4.25 pts/ac).

Insecticides used during the growing season were Asana (8.0 oz/ac), Portal (1 qt/ac), Sevin (1qt/ac) and Venom (8 oz/ac). Asana was applied on 22 June 2018; 6 July and 29 August 2018. Portal was applied on 11 and 13 July 2018; Sevin was applied on 31 May, 13 July and 3 August 2018. Venom was applied on 6 July and 3 August 2018. Insecticide products were applied in 2 rotations to avoid potential development of insect resistance.

A total of 51 lbs/ac N, 0 lbs/ac P and 183 lbs/ac K were applied pre-plant. Liquid fertilizer with 4-0-8 analysis was initially applied through drip tape fertigation on 21 May 2018 and similarly on the following dates; 25 and 30 May 2018; 1, 4, 6, 8, 11, 13, 15, 18, 20, 22, 25, 27 and 29 June 2018;2, 5, 9, 11, 13, 18, 20, 25, and 27 July 2018; 1, 8, 10, and 13 August 2018. A total of 162 lbs/ac N, 0 lbs/ac P and  323 lbs/ac K were applied via fertigation throughout the growing season.Cumulative totals of applied fertilizer for the growing season were: 213 N lbs/ac, 0 P lbs/ac, 506 K lbs/ac, respectively. Soil tests indicated that soil phosphorus levels were sufficient and therefore no fertilizer that contained phosphorus was applied. Although there were 5 harvests in this study, we anticipate reducing total N and  K fertilizer by at least 33% in 2019.

Fungicides were initially applied on 22 June 2018 and similarly on the following dates: 6 and 13 July 2018; 3 and 29 August 2018. 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), Forum (6 oz/ac), Inspire (6 oz/ac), Manzate (3 lb/ac), Presidio (4 oz/ac), Previcur (1.2 pt/ac), Procure (8 oz/ac), Ranman (2.75 oz/ac), Revus (8 oz/ac) and Tanos (16 oz/ac). Insect and disease pressure was minimal throughout the season with the exception of a flare up of spider mites that were scattered within a few plots just prior to first harvest. Two applications of Portal were applied for mite control on 11 and 13 July 2018. Overall, superior plant health supported excellent crop yields. Each fruit was harvested when ripe, weighed and categorized statistically by size category.

Standard size triploid watermelon harvests (5) took place on: 24 and 31 July 2018; 6-7, 14, and 24 August 2018. 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 were established in the field on 23 May 2018. Plot size for mini triploid size watermelons was 1 row, 8 plants per plot, 15 feet long with alleys of 8 feet between plots. Diploid ‘SP-7’ (4 plants/plot) was used as the pollinizer for the 2018 growing season. Row middles were 10 feet for all watermelon cultigens and in-row spacing was 1.88 feet for the mini size triploid watermelons. Mini triploid watermelon harvests (5) occurred on: 24 and 31 July 2018; 6, 14 and 24 August 2018. For the mini triploid watermelon study, 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 w re 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 a7/16” 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.
