On-Farm Corn and Soybean Population Demonstration Trials

Authors: , , , , ,


Corn and soybean planting is one of the most critical operations of the season. As corn and soybean seed prices continue to rise, and grain prices fall, it is important for farmers to find a population that maximizes both yield and profit. Planting too high of a corn population can result in increased barrenness and thus lower yields, but too low of a population also can result in lower yields. Past studies have indicated soybean yields are similar across a wide range of populations, but too low of a population can result in reduced yields and too high of a population can reduce profits. The objective of these trials was to investigate the effect of various plant populations on corn and soybean yield.
