On most Nebraska rainfed farms, soybean and corn are usually rotated. On irrigated fields, however, the rotation sequence tends to shift to more years of corn between soybean, and in some cases, corn is grown continuously, year-after-year.
A review of 2016 growing conditions across Nebraska sheds light on a number of factors that may have contributed to reduced yield in individual fields. An understanding of these factors may be helpful when selecting seed for 2017.
UNL agronomists and educators responding to grower questions surveyed a number of corn fields this week and found a range of corn ear issues: short husks, dumbbell-shaped ears, and multiple ears per node. The article describes and discusses the situation, potential stress agents, and the development of corn. It also encourages growers to check their fields pre-harvest to better assess causes of potential yield loss.
