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

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.

Routes of nitrogen loss in the soil

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.

Trial studying efficacy of products on Palmer amaranth

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.

Fertilizer P for Corn: Update of Research Findings and Revised Recommendations

January 9, 2019
Results of research conducted since 2000 to address fertilizer phosphorus (P) for corn will be reviewed. The current fertilizer P recommendations for corn will be discussed and revised recommendations presented at the 2019 Crop Production Clinics.

Soybean damage from application of micro-rates of dicamba pesticide.

Effects of Dicamba Micro-Rates on Yields of Non-Dicamba Soybeans

January 9, 2019
This study looks at the sensitivity of non-DT soybean types (Conventional, Liberty Link, and Roundup Ready) to micro-rate applications of Clarity, Engenia, and XtendiMax at several growth stages.

Dry bean weed management trial

The Importance of Early Season Weed Control

January 9, 2019
Do early season weeds have the same impact as later season flushes? Researchers here report on a 2018 study conducted in dry bean to compare how soon after planting crop yield was impacted by weed presence.
