Corn

From Across the Field 7-16-2020

Crops Continue to Progress

It is hard to believe we are already in the middle of July and if you look closely, it shows. Buckeye tree leaves are already showing red leaves which is common this time of the year.

Most of the county was fortunate to get some rain in the last week, which was much needed, as hot and dry continues to be the weather pattern at least through this weekend. During my weekly crop tour across the county, there are tassels and silks appearing in corn fields, which means pollination is among us.

In this week’s C.O.R.N. newsletter Dr. Alex Lindsey describes the impact of heat and moisture has on corn pollination. Continue reading From Across the Field 7-16-2020 →

Revisiting Corn Use for Ethanol

By: Todd Hubbs, Department of Agricultural and Consumer Economics, University of Illinois.  farmdoc daily (10):133

Stronger export numbers and lower acreage boosted corn prices since the end of June.  Concerns about demand weakness in ethanol production emerged recently.  A recovery in economic activity helped ethanol plants ramp up production as gasoline demand increased.  A resurgence in virus incidences threatens ethanol production over the short run and injects uncertainty into long-run prospects.

Gasoline demand recovered to almost 89 percent of pre-coronavirus lockdown levels in early July.  Despite this positive development, the recovery in demand flattened out over the last few weeks.  Gasoline stocks began to recede but still sit substantially above levels seen at this time of the year.  Attempts to reopen the economy hit a snag as the virus spread rapidly around the country after initial hopes saw a rapid opening in many areas.  At 8.648 million barrels per day, demand recovered substantially from the low point of 5.311 million barrels per day seen in early April.  The path back to normal gasoline demand levels appears stalled.  Ethanol production followed this recovery and will feel the implications of flattening gasoline use.

Corn Growth in Hot and Dry Conditions

By: Alex Lindsey and Peter Thomison, OSU Extension

In recent days we have been experiencing 90 degree F days with limited precipitation, and so we are starting to see some leaf rolling in corn. Some of this may be related to reductions in soil moisture, but may be related to restricted root systems as well. Depending on the stage of corn at the time of these conditions, different effects on yield may be expected. Corn ear development occurs throughout the growing season, and extreme temperature or moisture stress at different growth stages will decrease different aspects of grain yield. Below is a quick summary of the yield component most affected by environmental stress at different growth stages: Continue reading Corn Growth in Hot and Dry Conditions →

Corn Consumption Showing Improvement

By: Todd Hubbs, Department of Agricultural and Consumer Economics University of Illinois

Uncertainties regarding the potential trade deal and coronavirus outbreak remain as negative forces for commodity markets.  Corn prices came through the difficulty relatively well over the last couple of weeks.  March corn futures prices continue to bounce around in a range between $3.75 and $3.95 seen since mid-December.  Over this same period, consumption in some key use categories for corn picked up substantially and corn basis remains strong.

Corn exports remain behind last year’s pace.  A recent uptick in export sales offers the promise of increased exports in the second half of the marketing year.  In the previous three weeks, net export sales came in at 39.6, 48.6, and 49.1 million bushels, respectively.  These net sales totals mark the first time all marketing year of three consecutive weeks over one million metric tons.  Total commitments as of January 30 sit at 897 million bushels.

Managing Stored Grain Through Winter

By: Jason Hartschuh, OSU Extension Crawford County

Managing stored grain throughout the winter is an important part of your grain marketing plan for farm profitability. This winter we are already receiving reports of stored grain going out of condition, which can lower the value and be a hazard to those working around the grain facility. At a minimum, stored grain that has gone out of condition can cause health hazards, especially when grain dust contains mold and bacteria. Out of condition grain can also form a crust or stick to the bin walls and if someone enters the bin for any reason an entrapment could occur. For more information on safety when working around grain visit http://go.osu.edu/AFM and listen to episode 41 of the podcast on grain bin safety.

2019 Ohio Corn Performance Test: Regional Overviews

By: Rich Minyo, Allen Geyer, David Lohnes, Peter Thomison OSU Extension. Previously published in CORN Newsletter.

In 2019, 163 corn hybrids representing 20 commercial brands were evaluated in the Ohio Corn Performance Test (OCPT). Four tests were established in the Southwestern/West Central/Central (SW/WC/C) region and three tests were established in the Northwestern (NW) and North Central/Northeastern (NC/NE) regions (for ten test sites statewide).  Hybrid entries in the regional tests were planted in either an early or a full season maturity trial. These test sites provided a range of growing conditions and production environments. Continue reading 2019 Ohio Corn Performance Test: Regional Overviews →

How Reliable will this Year’s Test Plot Data Be?

By: Laura Lindsey and Peter Thomison, OSU Extension

Ohio’s corn and soybean crops experienced exceptional growing conditions in 2019, including record rainfall in May and June followed by drier than normal August and September conditions in many areas. As a result of the early season saturated soils, corn and soybean planting was delayed across most of the state. For soybean, planting date is the most important cultural practice that influences grain yield. Planting date is also a major factor affecting crop performance and profitability in corn. The persistent rains and saturated soils caused localized ponding and flooding. These conditions resulted in root damage and N loss that led to uneven crop growth and development between and within fields. Agronomists often question the value of test plot data when adverse growing conditions severely limit yield potential. Continue reading How Reliable will this Year’s Test Plot Data Be? →

Be on the Lookout for Mycotoxins in Livestock Feed

By: Jennifer Shike, previously published by Farm Journal’s Pork online

Producers need to be diligent about monitoring for mycotoxins in livestock feed this winter on the heels of weather conditions that promoted their growth this fall.

Kansas State toxicologist Steve Ensley says Kansas’ summer drought conditions led to a heightened risk of aflatoxin in the state’s grain crop, while wet conditions during the 2018 harvest also made that grain susceptible to fumonisin.

“This year we have already had some death losses associated with mycotoxins in pigs and horses and so we’ve measured just a very few samples of corn and found very high concentrations of fumonisin and aflatoxin,” Ensley says. “I’m very concerned that it may be a bigger health issue statewide than the localized cases we’ve seen so far.” Continue reading Be on the Lookout for Mycotoxins in Livestock Feed →

Field Drying and Harvest Losses in Corn

By: Peter Thomison, OSU Extension

According to the USDA/NASS (https://www.nass.usda.gov/) as of Sunday, Oct. 27th, 37 percent of Ohio’s corn was harvested for grain, compared to 62 percent for last year and 56 percent for the five-year average. Late corn plantings and sporadic rain in some areas are not helping with field drying. Some growers are delaying harvest until grain moisture drops further. However, these delays increase the likelihood that stalk rots present in many fields will lead to stalk lodging problems. Leaving corn to dry in the field exposes a crop to unfavorable weather conditions, as well as wildlife damage. Continue reading Field Drying and Harvest Losses in Corn →

Are Modern Genetics Worth the Money?

By: Harold Watters, Ohio State University Extension

I have conducted a number of trials and comparisons over the years and generally have concluded that new is better when it comes to choosing a hybrid or variety. One such comparison I have been making over several years now is of a modern hybrid to open pollinated corn varieties. This may be used as a comparison for those who grow open pollinated corn for sale as organic, although I used herbicides here for weed control. For 2019, I compared a modern traited hybrid, an early modern traited hybrid, a modern open pollinated variety and several older open pollinated varieties.
