Skip-Row Corn Provides Improved Drought Tolerance in Dryland Corn March 1, 2017

Research in Nebraska over a number of years has documented how skip-row corn can offer yield benefits in dryland production systems. Because water in the soil between widely spaced rows cannot be reached by the crop until later in the season, the water is available July and August, when plants are in the silking to blister stages and particularly sensitive to drought stress.
