Interpretive Summary:

Technical Abstract: Corn grown for grain is becoming increasing important in North Dakota even though corn productivity is constrained by sub-optimal temperatures and a short growing season. Corn production is increasing throughout the state including regions where corn growth is routinely limited by inadequate moisture. There is little information available on the best strategies for growing corn in the drought prone regions of North Dakota. Experiments were established in 2004 at Williston, Minot and Mandan to determine the effect of plant density and hybrid maturity length on grain yield and grain moisture content at harvest. Treatments consisted of a factorial combination of plant density (29,500 and 59,000 plants/ha) and hybrids with differing maturity lengths (82-90 RM). Corn development at all locations was delayed by cool spring temperatures and frost prior to the 5 leaf stage. Corn growth was not constrained by moisture early in the season. Grain yield and grain moisture will be measured at harvest. These data will be used to develop recommendations on the best combinations of hybrid maturity and plant density to optimize corn production in drought prone regions of North Dakota.
