SCHMIDT: Elgin-ND available
The Pierce County Crop Improvement Association has an adequate supply of Elgin-ND Hard Red Spring Wheat available for distribution to commodity growers for the 2014 growing season. 2014 is the first year that Eligin-ND will be available for general distribution to commodity growers. The Elgin-ND HRSW variety is priced at $14.30 per bushel.
Elgin-ND has performed well in variety trials across the state showing high yield potential, good quality and disease protection.
In terms of yield Elgin-ND has high yield potential. According to North Dakota variety trial results for 2012, Elgin-ND’s yield beat five of the top six most popular varieties for the year in eastern North Dakota. The average yield in 2012 for Elgin-ND across eastern North Dakota locations was 62.6 bushels per acre, compared with 58.2 bushels for Barlow, the variety with the most acres planted in the state.
In addition to yield, protein levels of Elgin-ND are very good. Glenn is known for its quality and high protein, but Elgin-ND’s protein rivals it.
Elgin-ND’s disease resistance package includes resistance to prevalent leaf and stem rusts and moderate resistance to scab. The North Dakota Hard Red Spring Wheat Variety Trial Results for 2013 and Selection Guide can be accessed on the web at: www.ag.ndsu.edu/publications/landing-pages/crops/nd-hard-red-spring-wheat-variety-trial-results-2013-a574-13 or by picking up a copy at the Pierce County Extension office.
The hard red spring wheat breeding program at NDSU developed Elgin-ND. It is widely adapted to the spring wheat region of North Dakota. Elgin-ND is protected under the Plant Variety Protection Act with Title V. Only certified seed may be sold legally.
Seed of Elgin-ND is available through the Pierce County Ag Improvement Association. To order Elgin-ND seed, contact the Pierce County Extension office at 776-6234 ext. 5.
Winter Grain Storage Management
Grain should be cooled to about 25 degrees for winter storage to limit moisture variation and control insect problems. Insects in stored grain can be killed if this temperature is maintained during winter storage.
Grain in storage needs to be checked to be properly managed. Check for indications of moisture such as grain crusting or condensation on the bin’s roof, and smell for musty, moldy odors. But just this is not adequate. It is essential to use a probe to collect samples from various locations.
Check and record the grain temperature at several locations in the bin. Both the temperature and trend in temperatures are important; both mold growth and insect activity will cause the temperature to increase.
Check the grain moisture content. The reading must always be adjusted based on the grain temperature, but remember that the moisture content reading is inaccurate at temperatures below 40 degrees. It is best to check the moisture content of collected samples after the grain has been warmed to room temperature. Warm the grain in an air-tight container, such as a plastic bag, to prevent the moisture content from changing during warming.
Also check the samples for insects after they have warmed to room temperature. Placing the grain on a white background will make it easier to see the insects. Cooling the grain to about 25 degrees is the best way to control the problem if insects are found.
Make sure all openings in the bins, such as vents and ducts, prevent snow from getting into the bin. These openings need to be there to allow air flow during aeration, but may be closed once aeration has been completed. Fans should be covered when they are not operating.
High-moisture grain can be stored over the winter as long as the grain is kept cold. Corn at 24 percent moisture can be stored for about 130 days if the grain temperature is below 30 degrees, but the allowable storage time decreases drastically at warmer grain temperatures. The estimated allowable storage time for 24 percent moisture corn is 40 days at 40 degrees, but only 15 days at 50 degrees.
Corn below 21 percent moisture can be natural-air dried in the spring using an airflow rate of at least 1 cubic foot of air per minute per bushel by starting the fans when the average temperature is about 40 degrees. Corn at moisture content exceeding 21 percent should be removed for high-temperature drying before temperatures rapidly warm during March. Solar heat gain will warm the top of the bin and the south wall to temperatures exceeding outdoor air temperatures.
Grain will deteriorate even with the fan operating. Airflow keeps the grain cooled to near the air temperature, but the grain still will deteriorate at a rate based on the grain moisture content and temperature.
Grain is more susceptible to deterioration if it is immature or the kernel integrity is damaged. Poor quality grain should be dried to a moisture content about 1 percentage point lower than good quality grain. Poor quality grain should be monitored more closely during the storage period.
There will be a grain moisture content variation among kernels after drying in a high- temperature dryer if there was a moisture content variation before drying. For example, if the kernels vary in moisture between 20 percent and 30 percent before drying, the variation may be between 12 percent and 18 percent after drying. Due to the variations in maturity within fields and even on a single corncob, there is potential for variations in stored grain moisture content. Grain segregates based on size and density as it flows into a bin. If there is a variation in kernel size, pockets and variations should be expected. Some of these pockets may contain grain at higher moisture content. If a grain spreader has not been used to fill a bin, normally the smaller and denser material accumulates in the center of the bin.
Grain germination may be damaged before visible mold is present on the kernels. This may happen when wet grain remains in a bin at moderate temperatures for an extended period before it is dried. Germination should be checked on malting barley and seed that was not dried within three weeks of being placed in the bin.
There is the potential for bin vent screens to become iced over when operating fans near or below freezing temperatures causing damage to bin roofs. If fans must be operated near or below freezing temperatures, it is recommended to leave a bin fill-hole or manhole unlatched as a pressure relief valve if the air is being pushed up through the grain. If humid air is being pulled in through bin vents at temperatures near freezing, provide an unscreened opening, such as the manhole, for airflow.
Check the grain every couple of weeks until it has been cooled to 20 to 25 degrees. Check dry grain at least monthly during the winter and wet grain every couple of weeks. Measure and record the grain temperature. Check the grain moisture content and examine the grain in several locations. Search for small changes that are indicators of potential problems.
High moisture grain is more likely to develop a crust, which may hide a cavity formed when the grain is unloaded. The chance of suffocating is high if you fall into the cavity and are covered by the grain. Grain stuck to the wall of a bin can also trap and suffocate a person attempting to break it loose. It is not healthy to breathe mold spores and suspended mold particles that may be in the air of a bin with deteriorating grain. Always wear at least an N-95 rated mask or respirator if in a bin with spoiled or moldy grain.
