FROM AROUND THE STATE
ISSUE 2 May 9, 2002
As of May 8th, heavy snow has blanketed the north central and north western regions of the state. The North Central Research Extension Center, at Minot, North Dakota, has recorded 14 inches of snow from April 27 to May 7 with another 4 inches expected today (May 8). The 14 inches of snow from April 27 to May 7 equals the amount of that fell from November, 2001 to February, 2002.
Continued snowy weather and cold soil temperatures have resulted in planting progress to fall behind the long term average. The moisture is welcome for the sub-soil moisture level is short to very short across most of the region. There is no doubt that spring planting will now be delayed to where all cool-season crops will be planted later than the optimum planting date. There is only 20% of the canola planted across the north central region and only a small percentage of small grains has planted as well. Pastures, alfalfa, and winter wheat have been slow to grow due to the cold temperatures. There has been very little weed or volunteer growth of any kind. Top-soil temperatures the last two weeks have barley reached 40 degrees F with 37 degrees F being more the average. There are reports of canola and spring wheat that have been in the ground for 21 days now and the seed has barley sprouted. Hopefully once the snow has ended, the sun will appear and normal temperatures will return, so growers in the region can catch-up with their planned planting intentions.

During May 1 to 7, area rainfall amounts were 0.65 inches or less as recorded at NDAWN sites. Black soil temperatures at the 4-inch depth ranged from the mid 30's to low 40's F on May 7. Fieldwork generally was taking place throughout the region during the week ending May 4. Recent moisture (rain and snow) plus the continuous cool temperatures have stopped fieldwork and hindered development of planted seeds. For example at Carrington, HRS wheat planted on April 24 had coleoptile length of less than 0.5 inches when checked on May 7.
Reports across the region indicate winter survival of alfalfa and winter cereals is satisfactory. There is a wide spread of seeding progress between counties north of I-94 compared to counties near the South Dakota border. In Dickey, LaMoure, McIntosh, Ransom and Sargent counties, small grain seeding is 75 to 95% complete. Early-planted small grain fields have started to emerge. In Eddy, Foster, Sheridan and Wells counties, 5% or less of small grain, canola, and flax seeding is complete. Corn planting is about 50% complete in Dickey, LaMoure, Ransom and Sargent counties and a small percentage of soybean acres have been planted. Corn planting date deadlines are fast approaching and general concern exists with timely seeding of cool-season crops. Pasture growth is slow.

Producers made the most of field conditions (April 29 – May 5). Much of the canola and pea acreage in southwest North Dakota was seeded by May 5. Some producers have reported that they have completed planting of spring wheat while others reported that they were just getting started. Some corn planting occurred late in the week. Barley sown at the Dickinson Research Extension Center and at the Hettinger Research Extension Center on April 12 and April 16 and canola seeded in the fall (November 16 and 29) as well as spring seeded (April 12 and 15) is beginning to emerge. Some producers have begun to report the emergence of canola and small grains seeded in mid April. However, no reports of flea beetle feeding activity have been reported on canola. The weather has been too cold for flea beetles. Oats at Hettinger have emerged. Peas have not emerged at either Research Center.
Producers in Golden Valley, Slope, Hettinger Counties found army cutworms this past week. This pest had not caused any extensive damage to date since it has been relatively cold but as the weather warms and crops begin to emerge producers should scout fields for areas where plant stands appear to be thin or where plants are "disappearing." Phil Glogoza, NDSU Extension Entomologist, discusses life cycle, economic treatment thresholds, and control in this Crop and Pest Report. Producers should refer to this section of the newsletter or contact your county agent for further information.
Snow and rain have fallen at the Dickinson Research Extension Center beginning late on May 5 and has continued through to the morning (7:30 AM) of May 8. Total precipitation received during that time at Dickinson was 0.79 inches. Hettinger has received 0.45 inches over the same period of time.
Some producers reported that a few early-seeded canola fields may have experienced freeze injury. Producers should wait a week or so after the snow melts off the field before assessing freeze injury. Some of the cotyledons may be a bit yellowed but as long as the growing point is still alive, canola should grow out of the injury once the weather warms. The highest yielding production field that I have ever seen was where the canola emerged, exposed to cold temperatures, and then covered by two feet of snow for a couple weeks. That field yielded 3,000 pounds per acre.
