Modern corn hybrids, shown here, differ significantly from hybrids of 50 years ago.

Corn Growth and Development: Updating an Old Paradigm of Dry Matter and Nutrient Accumulation and Partitioning

From the 1960s to the 2000s corn hybrids have changed dramatically in appearance and yield. Nutrient content, concentrations and partitioning also have changed and are the focus of this article for the Nebraska Crop Management Conference Jan. 28-29.

Corn Growth and Development: What We Have Learned About Corn Development From Studying Ear Issues

In an effort to better understand the causal agents of ear formation issues first seen in corn in 2016-2017, researchers laid out an experiment in 2018 to typify types of ear formation damage as well as possible factors contributing to damage.

Nebraska Plant Pathology: A Culture of New Diseases

Though relatively small, UNL's Department of Plant Pathology has played a significant role in the discovery of many economically important plant diseases, including most recently, a new fungal pathogen causing Fusarium head blight of wheat. This article is from the 2019 Nebraska Crop Management Conference Proceedings.

Weed Management

Pollen-Mediated Gene Flow and Transfer of Herbicide-Resistant Alleles

Pollen-mediated gene flow at a distance could allow the spread of rare herbicide-resistant alleles and favor the evolution of multiple herbicide-resistant biotypes through the accumulation of different resistant genes in an individual weed or weed population.
