2017 North Carolina and Tennessee Pumpkin Cultivar Evaluations

Horticulture Series # 219

Principle Investigators:

General Cultural Practices

The pumpkin cultivar evaluation trial was grown on black plastic mulch and were fertigated with drip irrigation. Pesticides used on all plots were chemicals labeled for that crop, (North Carolina Agricultural Chemicals Manual, 2017).

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.

Introduction

In 2017, North Carolina ranked 4th in pumpkin production in the US behind Illinois, Texas and California. This makes North Carolina the largest pumpkin producing state on the eastern seaboard. The economic value of the pumpkin crop in North Carolina was reported to be more than 15 million dollars in 2016. The USDA- National Agricultural Statistics Service reported pumpkin acreage in North Carolina and Tennessee at 3,800 and 1,900 acres, respectively. 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 climate and soils of the region. Collaborative pumpkin cultivar evaluation trials 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 in less disease pressure. According to the USDA Economic research service, consumer demand for specialty varieties has been increasing in recent years. The pumpkin cultivars included in this trial were mainly evaluated for yield. However, each cultivar was also rated for shape, color, suturing, vine habit, handle characteristics, fruit size measurements and powdery mildew symptoms. The fruit obtained from each replicated cultivar are also identified in a photograph. Several other cultivars were also included in the trial as observation plots (non-replicated) and most of these cultivars are identified in a photograph where available.

Materials and Methods

This trial was conducted at the NCSU Mountain Research Station, Waynesville, NC, and was a  collaboration between North Carolina State University and the University of Tennessee. Seeds were planted on 21 June 2017. A total of 72 cultivars were evaluated, with 41 cultivars being un-replicated and for observational purposes only. The remaining 31 cultivars were evaluated in a randomized complete block (RCB) trial with 4 replications. Each plot measured 20 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 (260 lbs/acre of 34-0-0 and 65 lbs/acre of (18-46-0) broadcast applied and incorporated into the beds on 14 June before laying plastic mulch, providing 100 lbs N, 30 lbs P and 0 lbs K per acre. Fertigation with either KNO3 (13-0-44) or CaNO3 (15.5-0-0) was applied through drip irrigation on 2, 9, 16, 23 and 30 August 2017; 6 and 15 September 2017. A total of 150 lbs/acre N, 30 lbs/acre P and 66 lbs/acre K was applied to the trial site throughout the entire growing season.

Insecticides were only applied when needed and were applied at labeled rates for pumpkin production in North Carolina. Coragen was applied through drip irrigation on 5 July 2017 and applied at the labeled rate that can be referenced in the North Carolina Agricultural Chemical Manual or the North Carolina Vegetable Production Guide. The fungicide program implemented included the following products which were alternated to reduce potential for development ofdisease resistance: Fontelis, Previcur Flex, Presidio, Pristine, Procure, Rally, Ranman, Quadris, Quintec and Zampro. 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, 2017. Fungicides were applied every 7 to 14 days throughout the growing season beginning 12 July 2017 and repeated on the following dates: 24 July; 1, 14, 21 and 31 August; 7, 14 and 22 September 2017. Herbicides, Command (1pt/ac) and Dual Magnum (1pt/ac), were sprayed for weed control on 22 June 2017. Pumpkins were harvested on 5 October (106 days after planting). Yield per acre was calculated by extrapolating total yield from the 200 ft2 area of each plot. Five representative fruit from each plot were measured to find the average length and width of each cultivar. Pumpkin color, shape, and suturing; and handle length, thickness and attachment were rated subjectively for each plot.

Results

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

Mini

Six cultivars were evaluated in the mini size class (≤5.0 lbs). Crunchkin, Jack Sprat, Munchkin, Orangita and Prankster were all orange pumpkins, while Casperita was white. Average fruit size ranged from 0.5 lbs for Munchkin to 3.6 lbs for Prankster (Table 1). The smallest fruit were produced by Munchkin and Crunkin while the largest fruit in the mini category were produced by Prankster. Munchkin produced the most number of total fruit while Prankster produced the least number of total fruit per acre (Table 1). Jack Sprat produced the highest yield (15.0 tons/acre) while Crunchkin had the lowest yield (3.7 tons/acre) in the mini size category (Table 1).

Small

Four cultivars were evaluated in the small size class (5.1 – 10.0 lbs). Darling, Enza EX#16, Field Trip were all orange pumpkins while Tandy produced a buff colored pumpkin. Average fruit size was 5.9 lbs with Enza EX#16 and Tandy producing the smallest fruit (5.4 lbs) while Darling produced the largest fruit (6.8 lbs). Tandy produced the highest fruit per acre while Enza EX#16 produced the least fruit per acre (Table 1). Darling produced the highest yield (tons/per acre) and Enza #16 had the lowest yields in the small size category.

Medium

Fifteen cultivars were evaluated in the medium size class (10.1 – 20.0 lbs). ACX 7606, Cracker  Jack, Enza EX#3, Enza EX#5, Eagle City Gold, Gladiator, Magic Lantern, Orange Sunrise, Renegade,  SPU 6016, Skidoo Gold and Solid Gold were all orange pumpkins, while Blue Doll was blue/green,  Blush was pink/buff and Porcelain Doll was pink (Table 2). ACX 7606 had the smallest average fruit  size (10.1 lbs) while Magic Lantern had the largest average fruit size (19.9 lbs). ACX 7606 produced the greatest number of fruit per acre while SPU 6016 produced the least total number of fruit per acre.

Large

Six cultivars were evaluated in the large size class (≥20.1 lbs). Bayhorse Gold, Bellatrix, Early King, Hulk, Kratos and Rhea were all orange pumpkins. Bayhorse Gold produced the smallest average fruit (20.6 lbs) while Hulk produced the largest average fruit (25.6 lbs). Kratos had the highest total yield (tons/acre) and Hulk produced the lowest total yield in the large size class (Table 1.) Bayhorse Gold produced the highest total number of fruit per acre and Hulk produced the lowest number of fruit per acre.
