Weather Impacts to Pollination and Kernel Fill in 2020
August 13, 2020
For this year having what seemed to be good pollination weather, some are surprised regarding how much tip back we’re seeing. It’s important to count kernels long as there may be more kernels than one realizes in spite of tip back occurring.
2020 Corn Yield Forecasts as of August 4
August 6, 2020
Similarly to our previous forecast, there is a high probability of near-average yields for the majority of the irrigated sites. For rainfed corn, the scenario is diverse across regions.
Wind-Damage to Corn
July 16, 2020
Prior to storms July 8-9, plants were nearing tassel, a critical time for photosynthesis and pollination. These storms resulted in “flattened” corn from lodging/leaning in addition to bent and snapped plants. "Recovery" depends on a variety of factors.
2020 Corn Yield Forecasts as of July 14
July 16, 2020
Although it is still too early to make strong inferences about end-of-season yields for irrigated corn, there is a relatively high probability for near-average yields for a majority of sites.
Silk and Tassel Development in Corn
July 15, 2020
Silks and tassels are emerging and the smell of pollen is in the air in fields throughout the State! Two recent articles from Dr. Bob Nielsen, Purdue University, may be helpful for a refresher and also to learn something new regarding silk and tassel development and pollination.
2020 Corn Yield Forecasts: Approach and Interpretation of Results
July 9, 2020
The Yield Forecasting Center (YFC) will provide real-time information on corn phenology and forecasts of corn yield potential every three weeks, starting in mid-July, to aid growers and ag industry in making management, logistics, and marketing decisions through the 2020 season.
Q & A: What is Causing Problems with Soybean Emergence?
June 4, 2020
The past two weeks, we’ve received a number of calls regarding injured soybean plants during emergence. Additional questions include “What caused this?” and “Do I need to replant?” The following is what we’ve seen thus far.
Corn Ear Development Impacts from Post-emergence Pesticide Applications
June 4, 2020
Corn ear abnormalities have been noted the past few years. Tracing back the information on various field calls often pointed to a misunderstanding of proper growth stages when making post-emergence herbicide applications in addition to pre-tassel fungicide and insecticide applications.
