Wheat Injury Unlikely Despite Unusually Cold Temperatures

Carrie Knott, Extension Agronomist-Princeton, University of Kentucky

Most of the wheat crop in Kentucky is either still tillering (Feekes 4-5) or just beginning to joint (Feekes 6). Although this has presented management challenges this year, it also may have protected the crop against freeze injury from the unusually cold temperatures the past two nights.

On-Farm Grain Storage Fumigation Workshop

Doug Johnson, Extension Entomologist
The University of Kentucky Grain Science Working group will be offering a Grain Storage Fumigation Workshop on Tuesday May 13, 2014 from 1:00 PM to 4:30 PM CDT, at the UK-REC in Princeton, KY. This workshop follows the Annual Wheat Field Day that will be held at the center from 8:00 AM to noon the same day. These two programs are complementary, developed by the same working group, but are separate events. Additionally, the Fumigation Workshop will cover all grain crops. Each event will have its own registration and have requested separate pesticide continuing education units (CEU’s).

Wheat Development Delayed about 2 Weeks this Year

Carrie Knott, Extension Agronomist-Princeton, University of Kentucky

We all know that this year has been an unusually cold year.  I am sure many if not all of you have visited your wheat fields to determine the effect this year has had on wheat growth and development.  At the University of Kentucky Research and Education Center at Princeton, KY, visually the wheat crop is about 2 or 3 weeks delayed.

Significant Nitrogen losses suspected in Kentucky Wheat Crop

Unseasonably cold temperatures and frequent precipitation events this winter have presented very unique wheat management problems for Kentucky producers. The soil throughout much of Kentucky remained frozen until the end of February, which resulted in delayed wheat development. As of today, much of the state has only reached Feekes 2 or 3. This is the recommended growth stage to make the first application of nitrogen (N) for producers that utilize a split N application program for winter wheat production. Compared to most years, this represents about a 2-3 week delay in growth. Some producers began applying N on frozen ground in late January to reduce potential soil compaction issues later in the season and to provide flexibility for later management operations. Unfortunately, several rain events occurred after N application while the soil was still frozen and which increased the potential for N loss with surface runoff water.

University of Kentucky Student Learns about US Ag in China

Please see this excellent article written by Katie Pratt. John is a graduate student working on high yield soybeans funded by the United Soybean Board. He had a great opportunity to see how our ag products are marketed and used in China. Click here for the article.

Soybean High Yield Checklist

Chad Lee, Extension Agronomist, University of Kentucky
These soybeans went 90 bu/A
and hit every point on the checklist.
Based on the responses to the Corn High Yield Checklist we decided to define the key parameters to getting high soybean yields. You will see a lot of similar points between this checklist and the one for corn. Both of these checklists are intended to be a framework for where high yields start.

Checking for Soil Compaction

Soil compaction stunted this corn.
Crop yields may be limited by soil compaction. Subsoiling is the most common method used to alleviate soil compaction, but is a time consuming and costly operation. If soil compaction is suspected, it is best to identify the areas in the field where it exists, what depth the compaction begins, and what depth the compaction ceases. The best method to document this information is with a soil penetrometer. Most county Extension offices have penetrometers that may be borrowed to make these measurements.
