NDSU Crop and Pest Report


ISSUE 13  July 24, 2003

Southwest ND

Rainfall was very limited this past week over southwest North Dakota. The Beach NDAWN site reported the greatest amount of precipitation at 0.27 inches while Dickinson reported the lowest rainfall total for the area none. This past week Dickinson and Mott reported four days of temperatures of 90oF or greater while Beach, Hazen and Hettinger reported 90oF or greater only two days.

Barley and canola are fast approaching maturity. Some of the early seeded barley has been swathed and the first reports of canola being swathed have been received.

Canola producers should remember at this time of the year they should inspect fields every two or three days for seed color change. This change will first be observed in pods attached at the bottom of the main stem. Variations in fields will cause variations in plant maturity so check several areas in the field for color change prior to swathing. The suggested time to begin swathing is when a minimum of 15 to 20 percent of the seed on the plant is showing color change. With hot conditions expected the next several days producers should consider swathing during the evening or at night rather than during the day. This may reduce the chance of setting green seed due to heat but this is no guarantee. Visit with your county extension agent, area extension agronomist or review the on-line version of the Canola Growers Manual or NDSU Extension publication A1171 Swathing and Harvesting Canola for additional information on harvesting canola.

Some early seeded pea crops have been harvested. At the Dickinson Research Extension Center pea yields are averaging about 35 bushels/acre.
