Corn Growth and Development: Updating an Old Paradigm of Dry Matter and Nutrient Accumulation and Partitioning
January 23, 2019
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
January 23, 2019
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.
Variable Seeding Rate for Soybean
January 23, 2019
Discussion of findings from on-farm soybean research to identify uniform field management zones and the optimum seeding rate within each zone. This is from one of the presentations to be made at the Nebraska Crop Management Conference Jan. 28-29 in Kearney.
Cover Crop Grazing: Impacts on Soils and Crop Yields
January 22, 2019
Results from a three-year study in rainfed and irrigated no-till cropping systems in Nebraska suggest that moderate cattle grazing of cover crops may not negatively impact soil properties and crop production.
Pollen-Mediated Gene Flow and Transfer of Herbicide-Resistant Alleles
January 22, 2019
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. From the Nebraska Crop Management Conference Proceedings.
Critical Time for Weed Removal in Corn and Soybean is Delayed by PRE-Herbicides
January 9, 2019
Understanding the critical time for weed removal in corn and soybean would not only ensure effective weed removal and minimize unnecessary weed control inputs, but could potentially help minimize the development of herbicide resistance in weeds.
Profit and Nitrogen Use Efficiency Gain Using Sensor-Guided Fertigation
January 9, 2019
A UNL study of sensor-based and model-informed fertigation treatments confirms that sensor fertigation treatments are consistently the most profitable and efficient methods of applying N compared to current best management practices (BMPs).
