Native Warm-Season Grass Management and Planting Decisions for Alternative Forages

January 9, 2019
One of the most important drivers of productivity and cost effectiveness of annual forages is planting date. Having realistic planting date expectations is one key to proper species selection.

Double Cropping Field Peas with Cover Crops, Forages, and Short-Season Crops

January 9, 2019

Farmers throughout the Corn Belt may want to consider diversifying traditional corn and soybean rotations to increase agronomic sustainability and to spread financial risks associated with low market prices of corn and soybean. An alternative is a more diverse crop rotation using field pea (short-season grain crop) followed by cover crops, forages, or short-season crops (Figure 1).

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.

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.

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.

The Sunflower Pathology Working Group

November 15, 2018
While diseases are one of the three biggest yield-limiting factors of sunflower production, there was little information on how to identify and manage them until university plant pathologists joined in a collaborative effort to conduct research and develop educational resources.
