Effects on Profitability and Nitrogen Loss from Reducing N Rate for Corn
February 5, 2019
This study looks at how various reductions in nitrogen application rates in corn might reduce nitrogen loss to the environment and what the costs of those changes would be in yield and profit.
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.
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.
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.
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.
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.
Nitrogen Inhibitors for Improved Fertilizer Use Efficiency
January 14, 2019
This article looks at how some nitrogen inhibitors temporarily reduce populations of Nitrosomonas and Nitrobacter bacteria, the soil bacteria responsible for converting ammonium to nitrite and nitrite to nitrate as well as what to look for in product claims.
Palmer Amaranth Control in Dry Bean
January 14, 2019
Residual herbicides applied at or before planting are critically important to controlling emerged Palmer amaranth in dry bean. Research at the Panhandle REC assessed the efficacy of PRE and pre-plant incorporated (PPI) residual herbicide programs.
