Adult Alfalfa Weevil Emergence Delayed (05/09/13)

Alfalfa weevil was very damaging in North Dakota last year due to its early emergence and the drought stressed alfalfa. The early emergence may have been due to eggs, which successfully overwintered during the mild winter of 2011/12, and as a result they hatched into larvae which started feeding on foliage earlier than normal.

Planting Date Trumps Preplant Fertilizer Application (05/09/13)

The planting season, especially in the northern half of North Dakota, will be extremely compressed. Less than normal fall fertilizer application will mean that many fertilizer dealers will have long waiting lists for fertilizer application this spring. Since the dates are already ticking away, and planting dates optimal for highest yield potential will be reached in the next week or two depending on where the field is located, waiting several days for a fertilizer applicator to show up before planting is not a reasonable decision.

Projections for 2013 Sugarbeet Crop plus Soil Temperature and Sugarbeet Seed Emergence (05/09/13)

The projected total sugar use for 2013 is expected to be 11 million short tons raw value. About nine million tons of this sugar will be produced in the US with just over 5 million tons coming from sugarbeet. Total US sugarbeet acreage is expected to be about 1.2 million acres.

Late-Planting Small Grains and Corn in 2013 (05/09/13)

The long winter and slow melt of the snow this spring has substantially delayed planting this year. Small grains are cool season crops that require relatively cool temperatures in order to achieve high yield potential. Therefore, when planted late, small grains develop during warmer temperatures that are detrimental to yield.

Army Cutworms In Alfalfa (05/09/13)

Large numbers of army cutworms have been reported in alfalfa fields in southwest North Dakota, near Rhame. Larvae (or caterpillars) overwinter as partially mature larvae and are ready to start feeding on alfalfa, winter wheat, canola and other early planted crops as soon as the temperatures warm up.

Cool Stored Grain (9/13/12)

Warm temperatures may have helped this year’s grain harvest, but those temperatures also may have created conditions that can cause stored grain to deteriorate. Harvested grain temperatures of about 100 degrees are being reported. The optimum temperature for insect infestations and mold growth is about 80 degrees.

Grain Yield Not Related to Test Weight (9/13/12)

Grain yield is quantity in bushels; test weight is an indication of quality. Don’t confuse grain yield with test weight. Grain yield is expressed as bushels per acre, and the number of bushels is determined by dividing the pounds of grain by a standard bushel weight. For example, a bushel of wheat has been determined to be 60 pounds per bushel.
