Disclaimer

This publication presents data from the cultigen evaluation study conducted during 2019. Information contained in this report is believed to be reliable but should not be relied upon as a sole source of information. Limited accompanying detail is included but excludes some pertinent information, which may aid interpretation.

General Cultural Practices

The pumpkin and gourd cultigen evaluation study was grown on black plastic mulch and fertigated through drip tape. Pesticides used on all plots were chemicals labeled for that crop, (2019 North Carolina Agricultural Chemicals Manual & Southeastern US Vegetable Crop Handbook).

Introduction

In 2017, North Carolina ranked 4th in pumpkin production in the Eastern United States. The economic value of the pumpkin crop in North Carolina was reported to be more than 15 million dollars in 2016. There was estimated to be 4,500 acres of pumpkins grown in NC, with 3,000 of these acres being located in the mountains of Western North Carolina in 2018 (Travis Birdsell, personal communication). The USDA – National Agricultural Statistics Service reported pumpkin acreage in Tennessee at 1,600 acres in 2017. The crop carries a significant value to producers in both states and it appears as though production of this commodity is increasing in North Carolina. In the western part of North Carolina and in pockets of Tennessee, pumpkin production is extensive due to the favorable climate and soils of the region. Collaborative pumpkin cultigen evaluation studies have been conducted by North Carolina State University and the University of Tennessee for over a decade. Growing conditions in the higher elevations of these states seems to translate to less disease pressure. According to the USDA Economic Research Service, consumer demand for specialty pumpkins has been increasing in recent years. The pumpkin cultigens included in this study were mainly evaluated for yield and size. However, each entry was also rated for shape, color, suturing, vine habit, handle characteristics, fruit size measurements and powdery mildew symptoms. The fruit obtained from each replicated entry are also identified in a photograph. Several other cultigens were also included in the study as observation plots (non-replicated) and most of these cultigens are identified in photographs where available.

Materials and Methods

This study was conducted at the NCDA&CS Upper Mountain Research Station, Laurel Springs, NC, and was a collaboration between North Carolina State University and the University of Tennessee. Seeds were planted on 13 June 2019. A total of 54 entries were evaluated, with 20 being un-replicated and for observational purposes only. The remaining 34 entries were evaluated in a randomized complete block (RCB) study with 4 replications. Three replications were used to make yield comparisons and four replications were used to make quality comparisons. Each plot measured 18 feet long with 6 plants spaced 3 feet apart (in-row) and distance between-row spacing was 10 feet. The exceptions were the mini sized category where plants were spaced 1.5 feet apart and 12 plants were planted in each plot. Plant bed preparation included pre-plant fertilizer (265 lbs/acre of 19-24-10) broadcast applied and incorporated into the beds on 7 June before laying plastic mulch, providing 50 lbs N, 64 lbs P and 27 lbs K per acre. Fertigation with 20-20-20 was applied through drip irrigation on 2, 9, 17, 22, and 30 July 2019; 2, 6, 12, 16, 19, and 26 August 2019. Fertigation with LoKomotive (2-0-25 potassium acetate) was applied through drip irrigation on 22 and 30 July 2019; 6, 12, 19, and 26 August 2019. A total of 119 lbs/acre N, 146 lbs/acre P and 75 lbs/acre Kwas applied tothe study site throughout the entire growing season.

Insecticides were only applied when needed and were applied at labeled rates for pumpkin production in North Carolina. Admire Pro was applied through drip irrigation on 21 June 2019 and applied at the labeled rate that can be referenced in the North Carolina Agricultural Chemical Manual or the North Carolina Vegetable Production Guide, 2019. The fungicide program implemented included protectant products of Initiate 720 (chlorothalonil) or Roper (mancozeb) and the following products which were alternated to reduce potential for development of disease resistance: Microthiol, Presidio, Previcur Flex, Ranman, Sivanto 200 SL, Torino. These products are registered for use in this crop and were applied according to labeled rates that can be referenced in the North Carolina Agriculture Chemical Manual or the North Carolina Vegetable Production Guide, 2019. Fungicides were applied every 7 to 14 days throughout the growing season beginning 19 July 2019 and repeated on the following dates: 3 and 10 August; 1 and 8 September 2019. Herbicides, Command (24oz/ac), Dual Magnum (24oz/ac) and Sandea (0.5oz/ac), were sprayed for weed control on 26 and 27 June 2019. Row middles were sprayed with Roundup Power Max (1qt/ac) 3 May 2019. Pumpkins were harvested on 10 September (96 days after planting). Yield per acre was calculated by extrapolating total yield from the 180 ft² area of each plot. Five representative fruit from each plot were measured to find the average length and width of each cultigen. Pumpkin color, shape, and suturing; and handle length, thickness and attachment were rated subjectively for each plot.

Results

Pumpkin entries are discussed by size class and are organized in tables in alphabetical order. Results mentioned in the paragraphs below only correspond to the replicated entries.

Pie Pumpkin

Four entries were evaluated in the ‘mini’ size class (≤ 5.0 lbs). Average fruit size ranged from 0.5 lb for HMX 53D6821 to 3.4 lb for Warty Gnome (Table 1). HMX 53D6821 produced the least total yield at 5.2 tons/acre and Miniwarts was the highest yielding cultigen in the Pie Pumpkin category at 21.6 tons/acre. HMX 53D6821 produced the greatest fruit number per acre of all of the replicated entries, at 20,651 fruit per acre (Table 1). Fruit of these entries ranged in color. HMX 53D6821 and Miniwarts produced orange fruit, Casperita produced white fruit, and Warty Gnome fruit produced yellow fruit. Shapes were slightly flat to round (Table 2).
