PUMPKIN VARIETY PERFORMANCE TRIAL

Richard Greenland, Leonard Besemann and Heidi Eslinger


Results summary

           Pumpkins grow well in North Dakota. Early maturing pumpkins are usually best, but later maturing ones do well in some years. Most pumpkins are used for Halloween decoration, but a new market is now available for edible pumpkin seeds. In this study we evaluated 20 pumpkins, including 6 for edible pumpkin seeds.

MATERIALS AND METHODS


Soil:

Maddock sandy loam, Hecla sandy loam and Embden sandy loam; pH=6.2; 2.6% organic matter; soil-P was very high, soil-K was high; soil-S was low.

Previous crops:

2003 - field corn; 2002 - cabbage and onion; 2001 - sweetcorn.

Seedbed

preparation:

Disked on April 13 and May 26. Multiweeded (field cultivated) three times: twice on May 26 to smooth seedbed and once on May 27 to incorporate fertilizer.

Planting:

Seeds planted 1 ft apart in rows 9.5 ft apart on May 28. On July 5 thinned to an in-row spacing of one plant every 3 ft.

Plots:

Plots were 17 ft long by 8 ft (one row) wide.

Fertilizer:

On April 15, broadcast 20 lbs N/acre and 24 lbs S/acre as 20-0-0-24. Applied 50 lbs N/acre as 28-0-0 on May 27. Applied 50 lbs N/acre on July 16 as urea.

Irrigation:

Underground drip irrigation as needed.

Pest

control:

Weeds were controlled by rototilling and by hand weeding. No control of cucumber beetles was required.

Harvest:

Hand harvested September 27 to October 1.

RESULTS


Miniature pumpkins: New Gold Dust looked nicer but Jack-B-Quik had greater numbers.

Pie pumpkins: Trickster looked the best and had the highest percentage of marketable pumpkins and greatest yield.

Medium pumpkins: New Rocket was the nicest looking pumpkin, had the highest total yield and the highest percentage of marketable pumpkins.

Large pumpkins: Gold Medal F1 had the highest percentage of marketable pumpkins and the greatest yield. Hybrid 510 F1 had the most marketable pumpkins. Howden Biggie had the largest pumpkins. Appalachian was the nicest looking.

Seed pumpkins: Seed yields were 475 to 1026 lbs/acre. Yields probably would have been higher had there been a good stand of pumpkins for the seed type pumpkins. Johnny’s HL had the best stand. Seminis Hyb had the highest percentage of marketable pumpkins and percent seed yield per pumpkin weight, and the smallest seed. Victor’s C5 and CS-Lee 19 had the largest seeds.
