Nebraska soybean producers are being asked to answer a survey about their soybean fields and contribute to a benchmark study of current soybean production in Nebraska. Researchers from 10 north central states, including Nebraska, are collecting the data to identify factors that may be impeding growers from reaching full yield. See what they've learned in the first two years of the study and how they hope to use the information.
July is when growers start to see a variety of defoliators in Nebraska soybean fields. It's easy to overestimate the amount of defoliation and soybean plants can compensate for some leaf area loss. This article describes how to assess defoliation and provides basic treatment thresholds.
With cool wet conditions favorable for corn seedling disease development, growers are urged to scout for inconsistent stands and disease pressure. This week seedling diseases were documented in 10% of surveyed fields in Dodge County in eastern Nebraska, mostly in corn-after-corn fields in river valleys. Be sure to monitor seedling emergence and stand establishment across the state during the coming weeks so that if problems occur they can be detected as early as possible.
When deciding whether to replant a less than optimum corn stand, consider current stand, potential yield, and potential yield of replanted crop at this point in the season. The authors guide you through the process of assessing the stand, and next steps, if necessary.
Similar to last year’s heavy rains in early May, rain on May 9 and May 10-11 in portions of Nebraska have caused ponding and flooding across some fields. As of Sunday, May 8, USDA-NASS reported that 57% of Nebraska's corn was planted that is behind the 71% planting progress in 2015 but close to the
