In North Dakota, an estimated 862,000 acres of sunflowers were harvested in 2010. This was a decrease of 6,000 acres compared with 2009.
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.
North Dakota Hard Red Spring Wheat and Variety Trial Results for 2010 and Selection Guide - A574-2010
Hard red spring (HRS) wheat was harvested from 6.3 million acres in 2010, equalling the area harvested in 2009. Temperature and rainfall were favorable for high yield development throughout the wheat-growing regions of the state, resulting in an estimated yield of 45.5 bushels per acre (bu/acre), which was only 0.5 bu/acre below last year’s record yield. Protein content was lower than normal but generally higher than last year.
