GARDEN PEA HYBRID PERFORMANCE TRIAL, 2000
Richard Greenland, Leonard Besemann, and Heidi Eslinger
Table 30. Yield, plant height, and pod characteristics of peas
Green peas grow well in cool climates, therefore they should grow well in North Dakota. We planted 6 hybrids to evaluate how green peas grow here.
MATERIALS AND METHODS
| Soil: | Maddock sandy loam; pH=7.1; 2.5% organic matter; soil-P and soil-K were very high; soil-S was meduim. |
| Previous Crops: | 1999 - carrot and edibile bean; 1998 - potato and field corn; 1997 - sweet corn and cabbage. |
| Seedbed Preparation: | Disked on 29 October 1999. Multiweeded (field cultivated) four times; once to incorporate fertilizer on April 5, once to smooth the seed bed on April 17 and twice on April 18 to incorporate herbicide. |
| Fertilizer: | On April 4, broadcast 18 lbs N/acre and 20 lbs S/acre as 21-0-0-24. |
| Planting: | Drilled peas on April 19 with a grain drill. Spacing was about 6 seeds per foot in 12-inch rows. Seeds were placed 1½ to 2 inches deep into a flat, fine seedbed. |
| Plots: | Each plot was 6 ft wide by 17 ft long. |
| Irrigation: | Overhead sprinkler irrigation as needed. |
| Pest Control: | Weeds were controlled using Treflan (1 pt/acre applied preplant incorporated on April 18) and by hand weeding. No insect control needed. |
| Harvest: | The plots were harvested nine times from June 19 to July 10. Each hybrid was harvested 3 times. We did not have a tenderometer (used to determine when peas were ready to harvest) so we harvested every two to four days, starting when peas were probably too young, and recorded the yields, etc. and graded the peas as marketable or not marketable. Harvest area was 6 ft wide by 2 ft long. |
All of the peas seemed to be good quality. There was a wide difference in maturity in each variety - some pods were too mature, some were just right, while others where just beginning to fill. Stampede had the highest yields, especially of shelled peas. Mr. Big had high yields of unshelled peas, but it was mostly pod, so yield of shelled peas was low. Peas of the hybrid MP 7003 split even when very young.
How does the yield in these trials compare to commercial production in other areas? Knott's Handbook for Vegetable Growers, 4th edition, listed the average yield of unshelled, fresh-market green peas as 2 tons/acre and a good yield as 3 tons/acre. The yield we measured was pretty good compared to that standard.
We did not have any insect problems. We had some mold problems at the end of the season. More problems may develop if large acreages are planted. It appears from this trial that green peas have good production potential in North Dakota.
