PUMPKIN VARIETY PERFORMANCE TRIAL, 1996
Richard G Greenland and Leonard Besemann
Pumpkins grow well in North Dakota. Early maturing pumpkins are usually best. This replicated trial had 5 pumpkin varieties.

Table 51. Fruit characteristics.
MATERIALS AND METHODS
| Soil: | Egeland loam and Maddock sandy loam; pH=7.4; 2.3% organic matter; soil-K was very high; soil-P was high; soil-S was very low. |
| Previous crops: | 1995 - carrot; 1994 - sweet corn; 1993 - broccoli. |
| Seedbed preparation: | Disked on May 3. Multiweeded (field cultivated) on May 20 to smooth seedbed. |
| Planting: | Seeds planted 1 ft apart in rows 8 ft apart on May 21. On June 28 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 17, broadcast 14 lbs N/acre and 70 lbs P2O5/acre as 10-50-0, 16 lbs N/acre and 19 lbs S/acre as 21-0-0-24, and 94 lbs K20/acre as 0-0-60. On May 3 broadcast 50 lbs N/acre as 28-0-0. Side dressed 70 lbs N/acre as urea on June 19. |
| Irrigation: | Overhead sprinkler irrigation as needed. |
| Pest control: | Weeds were controlled by a stale seedbed, and by hand weeding. Chemigated Asana (8 oz/acre on July 12 and July 31) to control cucumber beetles. |
| Harvest: | Hand harvested Sept. 30 to Oct. 3. |
RESULTS
We had trouble with germination and emergence for Baby Bear this year so yields were down, but the quality was good. This is the first time we've had a problem with Baby Bear. Rocket and Tom Fox did well again this year. Rouge Vif D'Etampes is a processing type pumpkin.
