PUMPKIN VARIETY PERFORMANCE TRIAL
Richard Greenland, Leonard Besemann and Delores Anderson
Table 31. Early stand and yields of pumpkin
Table 32. Pumpkin fruit characteristics
Pumpkins grow well in North Dakota. Early maturing pumpkins are usually best, but later maturing ones do well in some years.
MATERIALS AND METHODS
Soil: |
Hecla sandy loam, Embden sandy loam and Maddock Sandy Loam; pH=6.6; 2.4% organic matter; soil-K and soil-P were very high; soil-S was very low. |
Previous crops: |
2000 - field corn; 1999 - edible bean; 1998 - tomato and pepper. |
Seedbed preparation: |
Disked on April 20. Multiweeded (field cultivated) twice on May 17 to incorporate fertilizer and smooth seedbed. |
Planting: |
Seeds planted 1 ft apart in rows 9.5 ft apart on May 18. On June 19 thinned to an in-row spacing of one plant every 3 ft. |
Plots: |
Plots were 20 ft long by 8 ft (one row) wide. |
Fertilizer: |
On April 19, broadcast 10 lbs N/acre and 50 lbs P2O5/acre as 10-50-0 and 18 lbs N/acre and 20 lbs S/acre as 21-0-0-24. Sprayed 50 lbs N/acre as 28-0-0 on May 17. Side dressed 35 lbs N/acre as urea on June 20. |
Irrigation: |
Underground drip irrigation as needed. |
Pest control: |
Weeds were controlled by rototilling and by hand weeding. Sprayed Asana (8 oz/acre on July 19, Aug 8 and Aug 15) and Sevin (1 qt/acre on July 30) to control cucumber beetles. Applied Ridomil MZ72 (2.5 lb/acre on July 24 and Aug 15), Topsin (.41 lb/acre on Aug 1 and Aug 27) and Maneb (2 lb/acre on Aug 8) to reps 1 and 2 to control disease. |
Harvest: |
Hand harvested Oct 3 and 4. |
Hybrid Pam had the highest quality, number and percentage of marketable pumpkins. Racer had good quality and the greatest marketable yield. Gold Standard, Racer and Autumn King were also good varieties. Some varieties had trouble maturing before harvest.
