South Central ND (07/12/18)

Information from the South Central region of North Dakota.

The region’s NDAWN station data indicate rain during July 1-9 ranged from 0.8 inch (Harvey) to 2.9 inches (Robinson), with the Carrington REC (CREC) receiving 2.3 inches. Soil moisture is adequate to excess (standing water now present in low areas of fields). The abundant moisture is increasing risk of scab and late-season foliar disease in small grain, and white mold and rust in dry bean. However, our crops are using significant moisture. For example, NDAWN data indicates corn emerged on May 10 used 1.7-2 inches of moisture during the week of July 3-9.

Winter cereals are nearing maturity and late-April seeded barley is right behind in development (dough stage to seed color loss).  Late-April seeded spring wheat is in the watery ripe to milk stages. Corn planted during the first week of May is beginning to tassle (VT stage). Based on NDAWN growing degree day units (GDDU) accumulated from May 1 planting date through July 9, the region’s corn has accumulated 1070 GDDUs (Wishek) to 1260 GDDUs (Oakes), which continues to be about 10-14 days ahead of the long-term average for the same period. Mid-May planted soybean fields are at full flower to early pod development (R2-3 stages).

The CREC Field Day is Tuesday, July 17. Two agronomy tours are scheduled at 9:30 a.m. and 1 p.m. that will showcase a wide variety of our crop management research. Tour info can be found at www.ag.ndsu.edu/CarringtonREC/
