When Weather Delays Planting – Now What?
May 26, 2017
Agronomists consider several options for those pushed into late planting due to heavy rains. Changing corn hybrids or soybean varieties is not recommended, nor is shifting to alternate crops.
Evaluating Early-Season Hail Damage in Corn
May 25, 2017
Factors to consider when assessing early-season hail damage in corn. Growers urged to wait 7-10 days after hail to make full assessment.
Watch for Palmer Amaranth in Conservation Reserve Program (CRP) Fields
May 12, 2017
Palmer amaranth has not been confirmed in conservation plantings in Nebraska; however, the identification and occurrence of Palmer amaranth in CRP fields in Iowa has raised concerns among weed scientists and growers about its spread into conservation plantings in Nebraska and offer some suggestions for growers.
‘Cross-Banding’ on Corn Leaves Due to Pre-Emergent, Cold Soil Temperatures
May 12, 2017
Early-planted corn at the university's South Central Ag Lab was not emerged during the late-April cold snap, but upon emergence displayed symptoms of “cross-banding”: yellow to pale green, horizontal bands ― perpendicular to the leaf midribs. These often appear in a similar position on other seedlings and at about the same height above ground on different leaves.
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.
