Absinth Wormwood Control

Absinth Wormwood Control - W838

Absinth wormwood (Artemisia absinthium L.) is a perennial forb which is easily recognized by its strong sage odor. The plant also is known as American or common wormwood, mugwort or madderwort, and wormwood sage. It is grown in herb gardens for the sage flavor of the leaves. The young flower heads are the source of aromatic oil used to prepare vermouth and absinth.

ND and SD Hybrid Sunflower Performance Testing 2011

North Dakota and South Dakota Hybrid Sunflower Performance Testing 2011 - A652

In North Dakota, an estimated 561,000 acres of sunflowers were harvested in 2011. This was a decrease of 301,000 acres compared with 2010. Table 1 contains acreage data for the past 16 years as reported by the North Dakota Agricultural Statistics Service, U.S. Department of Agriculture. The yield estimate on Dec 20, 2011, for all sunflowers produced in North Dakota during the 2011 season was 1,342 pounds per acre (lb/a).

North Dakota Soybean Peformance Testing 2011 A-843

North Dakota Soybean Performance Testing 2011 - A843

Soybean variety selection should be based on maturity, yield, seed quality, lodging, iron-deficiency chlorosis tolerance and disease reaction. Later-maturing varieties tend to yield more than early maturing varieties when evaluated at the same location. After determining a suitable maturity for the farm, comparing yields of varieties that are of similar maturity is important. Although late maturity increases yield potential, later-maturing cultivars are more risky to grow than earlier-maturing varieties because an early fall frost may kill a late-maturing variety before the beans have completely filled in the pods, which will reduce yield greatly. The best way to select a high-yielding variety is to use data averaged across several locations and years. Because weather conditions are unknown in advance, averaging across several years’ data will identify a variety that likely will yield well across different weather conditions. Selecting a variety that has performed well in dry and moist conditions is the best way to pinpoint a variety that does relatively well, regardless of weather fluctuations.

North Dakota Dry Pea Performance Testing 2011 A-1469

North Dakota Dry Pea Performance Testing 2011 - A1469

In North Dakota, field pea takes about 60 days from seeding until flowering and 90 to 100 days to maturity. The moisture requirement for field pea is similar to that for cereal grains. Field peas can be grown on a wide range of soil types, but drainage must be good because field peas do not tolerate saturated or soggy conditions. Field pea can be grown in a no-tillage or conventional-tillage cropping system. Field pea grows best when seeded into a weed-free seedbed and fertile soils. Land preparation for seeding is similar to that of wheat.
