Palmer amaranth has not been confirmed in conservation plantings in Nebraska; however, the identification and occurrence of Palmer amaranth in CRP fields in Iowa has raised concerns among weed scientists and growers about its spread into conservation plantings in Nebraska and offer some suggestions for growers.
Wheat fields are still looking green (Figure 1). However, development of several diseases is increasing. On April 26, stripe rust was confirmed in Nuckolls County in south central Nebraska and on April 27, it was found at low to moderate levels in research plots at the University of Nebraska-Lincoln’s Havelock Research Farm near Lincoln in Lancaster County (Figure 2).
With nighttime lows predicted to drop several nights this week, growers are advised to cautiously assess the potential for germination problems due to imbibitional chilling before planting. Agronomists advise checking soil temperatures in each field the day of planting as well as forecast temperatures for 24 hours (soybeans) or 48 hours (corn) after planting.
Farmers are increasing their soybean plantings for 2017, which likely means some are shifting to soybeans-after-soybeans. This article looks at what you should be considering at planting time as you consider changing your cropping sequence.
A review of 10 years of soybean research shows that reducing your seeding rate from 150,000 to 120,000 seeds/acre can result in a $10.69/acre savings without affecting yield (assuming a $60/unit seed cost at 140,000 seeds/unit).
Jerry Mulliken discusses what he's learned from conducting more than 30 research studies on his farm near Nickerson, Nebraska. On-farm research provides meaningful information specific to a farm's soils, farming practices, and local conditions, allowing growers to make management decisions with confidence.
