- High Irrigated Corn-to-Soybean Ratio in Northeast Nebraska Calls for Research Targeted at Increasing On-Farm Irrigated Soybean Yields. A look at 2001-2013 irrigated soybean yields in northeast Nebraska showed they were consistently below the state average. What are the implications and how can researchers use the corn/soybean ratio to help identify trends and potential problems?
- Stink Bugs Reported in Corn and Soybeans. Entomologists urge you to continue scouting crops for insects. Cool temperatures have slowed plant growth this summer, which means plants may be vulnerable to insects longer than usual.
- Southern Rust Update in Nebraska. This week southern rust was confirmed in Nemaha, Pawnee, and Richardson counties in southeast Nebraska and in Clay County in south central Nebraska; last week it was confirmed in Otoe County.
- Dig Corn Roots to Evaluate Rootworm Management. Larval feeding should just be ending, making this a good time to assess your management program. Waiting too long may allow regrowth and require closer scrutiny of roots.
- Heavy Infestation of Wheat Stem Sawfly in the Nebraska Panhandle. Dryland wheat is most seriously affected but some level of infestation also occurs in irrigated wheat.
- Extension Crop Report, Clay County: Rust, drought stress
- USDA NASS Crop Conditions. Corn progress near average; soybean growth ahead of average.
