ISSUE 15    August 17, 2006

Northeast ND

Rainfall this week was general across the region with about 3/4 inch at the minimum to over 4 inches in isolated areas. Barley harvest is nearly complete south of highway two. Acceptable malting quality was achieved with yields generally above expectations. Spring wheat harvest has begun in areas south of highway 17 and just getting started in northern areas. Quality is good with variable yields. Pockets of low rainfall areas reporting much below average yields while the rest of the region yields are at least average. Some sunflower fields have dropped ray petals and the rest are in various stages of bloom. Earliest corn is beginning to dent while earliest soybean has achieved R6 stage with most in R5 stage. Sunflower, corn and later planted soybean will benefit from last weeks rainfall. Dryness has hurt most corn yield potential and fields have high variability for yield within fields. Canola swathing is widespread with some fields harvested. Growers will be concentrating on spring wheat and canola harvests in the next few days. Some dry bean acreage has been cut with many fields ready for dessication or cutting. Pods are dry but a lot of green growth with potential for renewed growth will force many producers to manage regrowth. Flax is maturing with some fields ready for harvest.

South-Central ND

During the first half of August, rainfall recorded at NDAWN sites in the region ranged from 0.2 inches at Harvey to 2.2 inches at Oakes. At Carrington, rainfall from April 1 to August 13 totalled 7.7 inches, which is short 4.3 inches compared to the long-term average. Based on NDAWN estimates, the region’s average daily water use on August 15 ranged from about 0.1 to 0.2 inches for corn, soybean and sunflower. Corn growing degree day units from May 1 to August 15 at Carrington are about 250 units higher this year (total of 1705) compared to the average of the previous 5 years (1455).

The region’s small grain harvest is nearing completion. Spring wheat yield varies from 0 bushels/acre (drought stricken area in southwest) to reports of 70 bushels/acre in other areas. Wheat yield in the ‘Highway 281 corridor’ generally are in the 35 to 50 bushels/acre range with good quality. Canola harvest continues and flax harvest should soon be starting. The region’s corn is in the dough to dent stages. Soybeans are in the seed-development (R5-R6) stages and some early-maturing varieties are at physiological maturity (R7 stage). Dry bean are nearing maturity and some fields are being knifed. Sunflower stages range from flowering (R5) to yellowing back of heads (R8). Sunflowers continue to have potential as our best performing late-season crop.

Row Crop Tour on September 6 at Carrington

You are invited to attend a row crop tour scheduled for Wednesday, Sept. 6, at the NDSU Carrington Research Extension Center. The tour will begin at 4:30 p.m. and conclude at about 7 p.m. with a sponsored supper.

Participants will view field research trials and receive production recommendations on corn, sunflowers and soybeans. Discussion during the corn session will include plant development and management challenges with this season's adverse environment. Also, a preview will be given of future traits available with corn hybrids. The sunflower session will include a review of hybrid performance, plant screening for tolerance to sclerotinia (stalk and head rot), management of downy mildew, and impact of late-season sunflower insects. Soybean topics include review of season’s production issues, variety viewing, plant nutrition and specialized inputs, and aphid/spider mite management.

Additional information about the tour is available from the Carrington REC at (701) 652-2951 or on the Web at
