Wide-row wheat production (15-inch row width) is a consideration for farmers who may not own or maintain a drill. Additionally, wide-row wheat allows for the opportunity to interseed soybean prior to wheat harvest. With funding from the Ohio Small Grains Marketing Program, we have evaluated wide-row wheat production for two years. Generally, wheat produced in 15-inch row width yields less than wheat produced in 7.5-inch row width. However, the response to row width is variety dependent, so we recommend using the Ohio State Wheat Performance Test for 15-inch row width to help guide variety selection when producing wide-row wheat.
