Jun 17, 2024 · Heavy rains in late spring created flooding from Nebraska to Ohio. Finding a cornfield where at least part of it was replanted was easy. Corn was growing in some fields when ponding occurred. What determines whether corn survives after ponding? And if it survives, will there be lasting effects?

Jun 2, 2020 · If corn was up, mud or old crop residue and crud left on the plants may interfere with photosynthesis. Ironically, the best solution would be another rain to wash off plants and leaves. If mud and crud stays caked on plants, the likelihood for fungal and bacterial diseases increases.

Jul 3, 2024 · Portions of Iowa, South Dakota and Nebraska are grappling with the aftermath of flooding, while continuing to fight a swollen river. The Mississippi River is facing flood threats, too. The high...

Heavy rains can flood corn fields or create saturated conditions. Here, we discuss agronomic and disease issues when corn is exposed to prolonged periods of high soil moisture and cool temperatures.

Aug 9, 2024 · Root system damage to pollinating corn plants could potentially increase photosynthetic stress during the pollination period and grain fill, due to reduced root function. Flooding also can cause soil and mud to be deposited on corn leaves and within the whorl.

Apr 29, 2020 · Heavy and persistent spring rains can create saturated or flooded soil conditions that can injure or kill growing corn. Flooding reduces the exchange of air between the atmosphere and the soil, which damages corn plants by depriving plant tissues of …

May 19, 2022 · If a corn crop is able to be established in such field areas, it should be monitored for nitrogen deficiency symptoms. Plants exhibiting nitrogen deficiency often have an overall lighter-green color and yellowing along the mid-rib of …

Flooded and saturated soil conditions can impact the corn development, cause nutrient deficiencies as well as increase the risk of herbicide injury and disease incidence. These flooding repercussions all have the potential to reduce yields.

Jul 6, 2021 · Corn survival increases significantly if water levels do not submerge the growing point of plant and if the growing point was submerged less than 48 hours (Ciampitti et al., 2021). Corn root growth and function can also be significantly harmed following flooding, especially after soil oxygen has been depleted.

Late-season flooding can cause significant development and harvesting problems. Effects on plant development are dependent on crop stage at the time of flooding.
