Wheat: Recapping 2011 and Selecting Seed for the 2012 Crop


Noel Mues, Extension Educator

University of Nebraska-Lincoln, Extension, Furnas County

 

A dry late summer and early fall in 2010 resulted in many uneven wheat stands throughout much of western Nebraska and some areas of eastern Nebraska. Many growers went into the winter with low expectations for the 2011 harvest. Ample spring rains, some may say excessive rains, turned the moisture situation around throughout the state. However, with the moisture came problems with residue-borne fungal diseases such as tan spot, Septoria tritici blotch, and Fusarium head blight.

 

Severe drought conditions to our south limited movement of leaf and stripe rust spores into the state, which could have been disastrous had the spores arrived during our wet weather. Hail was the other unwanted scourge that rode in on the coattails of our above average rainfall.

 

Those fields missed by hail and disease issues, performed very well indeed. Average rainfed yields across the state generally were between 50 and 60 bu/ac, but ranged widely from 0 to more than 70 bu/ac. Test weights were generally good, but grain protein levels were generally lower than normal, typically falling between 9% and 12%.

 

The Furnas County wheat variety plot was located northwest of Arapahoe on land farmed by Scott Haussler. The chem-fallow plot was planted into corn stalks and featured 49 varieties/hybrids. The average yield for the plot was 50.3 bushels per acre. Tam 111 had the highest yield at 61.6 bushels per acre. Lower yields in this plot can be attributed to almost 40% hail damage.

 

The Red Willow County plot averaged 76.5 bushels per acre and an experimental variety, NE03490, had the highest yield at 90.2 bushels per acre.

 

Selecting Seed for Disease Resistance – While it is seldom wise to base next year’s production plans solely on this year’s results, wheat growers who saw a lot of disease issues may want to consider selecting wheat varieties with good resistance to the diseases of greatest interest. If plant emergence was a problem because of deep seeding to try and get seed in contact with moist soil, growers may wish to consider wheat varieties with a long coleoptile.

 

Compare Wheat Variety Traits 24/7 on the Virtual Wheat Tour – Whatever the coming season has in store, one of the most critical decisions a wheat grower will make is the choice of wheat varieties. One of the resources to use in making this decision is the Wheat Varieties Virtual Tour. http://cropwatch.unl.edu/web/wheat/virtual

 

Wheat growers can see a list of wheat varieties recommended for their part of the state, read about a variety’s characteristics, and compare those characteristics to other varieties of interest. Growers also can see how different varieties performed in nearby wheat variety trials and locate a certified seed dealer who carries the varieties they are most interested in buying.

 

Wheat variety recommendations are based on three-year average yield data and specialists’ experience with the varieties in their regions of the state. Given the highly variable climate of Nebraska, we do not advise that growers make variety selections based on just one or two years of test results.

 

The Wheat Varieties Virtual Tour site is updated each year in early August with the results from the latest statewide variety testing program. This ensures that growers have access to the most current information on winter wheat varieties when making their seed purchases.

 

Selecting adapted and complimentary varieties is one of the most important decisions a wheat grower will make for this season. Make a more informed decision by visiting the Wheat Varieties Virtual Tour.
