Considering the day to day and week to week variability in weather we’ve experienced and the wide range of regional conditions across Nebraska this year, scouting fields for kernel set and overall condition may be more important than ever. Check out these corn reports from across the state.
Timely control of volunteer wheat and other weeds is key to managing yield loss risk in your 2018 crop. Yield-limiting risk factors affected by weed control include wheat streak mosaic and other diseases, insects (wheat stem sawfly and disease vectors), moisture loss, and increased weed seed production.
Field day participants will be able to view field pea varieties and learn about rotational benefits and agronomic practices to profitably grow field peas and integrate them with existing cropping systems.
Most yellow field pea being grown in western Nebraska were at early vegetative stages (4th to 7th node or 1-5 leaf stages) during last week’s cold snap, but extensive damage is not expected due to the pea’s level of frost tolerance.Field pea tolerance to frost during early stages of vegetative growth is partially due to the “hypogeal” germination nature of the crop. For plant species with hypogeal germination (e.g., field pea, lentil, chickpea), shoot germination occurs belowground.
One of the challenges with spring burndown application is timing. Wet and windy conditions can delay spraying and under these conditions weeds can grow significantly in a few days. Waiting until planting to spray troublesome weeds such as marestail may be too late to achieve adequate control. In addition, waiting until soybean planting limits the available herbicide options since there are relatively few labeled effective burndown chemicals for spraying at this time. The following section identifies key treatment aspects to consider for several resistant varieties in Nebraska.
Fall-planted cereal rye is increasingly used as a cover crop in corn and soybean cropping systems in Nebraska. The authors address control of cereal rye through herbicide and mechanical measures and include a USDA NRCS map of recommended termination deadlines.
