Do I Need to Replant My Corn?
May 5, 2017
Considering whether your corn should be replanted? The authors look at types of plant damage at early growth stages and the effect on potential yield. It includes a table of relative yield potential of corn by planting date and population.
Risk of Freeze Damage in Early-Planted, Emerged Corn
April 28, 2017
Early-season freeze damage results in a range of potential yield impacts. Severe damage is often limited to low-lying areas within a field because cool air is heavier than warm air. Early season survival of corn plants is attributed to growing-point protection below the soil surface; however, a hard frost can penetrate the ground and kill plants. Regrowth of corn following freeze damage is often impeded by dead leaf tissue that can entrap new leaves.
Considering Non-Bt Traited Corn in 2017? Plan for More Scouting
February 8, 2017
If you're considering planting non-Bt corn this year, entomologists urge you to plan for the additional pest management practices (and associated costs) you may need to adopt, given this decision.
Harvest 2016 — When Corn Yields are Below Expectations
October 14, 2016
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.
Corn Ear Formation Issues Likely Correlated With the Loss of the Primary Ear Node
August 19, 2016
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.
