Seeding Rates for Broadcasting Cover Crops Into Late-season Corn and Soybean
August 31, 2022
The middle to end of September is a good time to establish cover crops by broadcasting seeds into corn or soybean before harvest, which allows the crop to capture more sunshine, growing degree days and rainfall.
2020 Corn Yield Forecasts: End-of-season Forecasts Suggest Near-average Yields for the Region
September 17, 2020
Our forecasts suggest a near-average year for irrigated corn at most sites. For rainfed corn, the scenario is diverse across regions.
2020 Corn Yield Forecasts as of August 25
August 27, 2020
Compared with our previous forecasts, there is still a high probability of near-average yields for the majority of the irrigated sites. For rainfed corn, the scenario is diverse across regions.
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.
