WINTER SQUASH VARIETY PERFORMANCE TRIAL
Richard Greenland, Leonard Besemann and Delores Anderson
Table 35. Fruit characteristics of squash
Table 36. Numbers and yields of squash
Winter squash grow well in North Dakota. A small, but steady, market is available within the state. There are also markets outside the state, especially if squash is stored, then shipped during the winter.
MATERIALS AND METHODS
Soil: |
Embden sandy loam; pH=6.8; 2.9% organic matter; soil-P and soil-K were very high; soil-S was low. |
Previous crop: |
2001 - field corn and soybean; 2000 - edible bean and potato; 1999 - carrot. |
Seedbed preparation: |
Coulter chiseled 15 inches deep on April 18. Multiweeded (field cultivated) on May 16 to smooth seed bed. |
Planting: |
Seeds planted 1 ft apart in rows 7.5 ft apart on May 16. On June 12 thinned to an in-row spacing of one plant every 3 ft. |
Plots: |
Plots were 20 ft long by 6 ft (one row) wide. |
Fertilizer: |
On April 18, broadcast 18 lbs N/acre and 20 lbs S/acre as 21-0-0-24. Side dressed 50 lbs N/acre as urea on June 13. |
Irrigation: |
Surface drip irrigation as needed. |
Pest control: |
Weeds were controlled by rototilling and by hand weeding. Sprayed Asana (8 oz/acre on June 10, 18, 25, and July 2) and Ambush (8 oz/acre on July 11 and 30) to control cucumber beetles. |
Harvest: |
Hand harvested Sept 26 and 27. |
Burgess buttercup had the largest and the fewest number of fruit. Cream of the Crop had the highest yield. The study had much variability.
