South Central ND (05/12/16)

Information from the South Central region of North Dakota.

The region’s NDAWN greg endresstations indicate rainfall of 0.2 inches or less during the past week (May 4-10). Additional rain would be welcome, especially for recently planted crop. Corn planted on April 30 has accumulated 95 to 125 growing degree day (GDD) units through May 10, and plants are emerging (120 GDD units required from planting to plant emergence).

Alfalfa has doubled in plant height during the last week, nearing 12 inches. Winter cereals are in the jointing to flag leaf stages. Barley and spring wheat has emerged with first-half April seeded crop at the 3-leaf stage (tillering). Small grain stands generally look very good with the exception of salt-affected areas. Essentially all corn is planted and planted soybean acres are near 50% for this region.

Pre-emergence herbicide application for planted row crops is challenging due to windy conditions, and low prospects for rain to move herbicide into the soil and activate before emergence of weeds. Foxtail and pigweeds are recently-emerged cropland weeds. Post-emergence herbicide application in small grain will also begin when environmental conditions are appropriate.

Weekly agronomy notes from the Carrington REC can be obtained by ‘liking’ or viewing the Facebook page: NDSU Extension Service – CREC Agronomy.
