Agronomy Talk: EARLY SOYBEAN GROWTH AND DEVELOPMENT

Author: Denny Cobb

A soybean seed has two distinct parts: the cotyledons and the embryo. The two cotyledons are the main food storage structure, which supply food during emergence and for the seven to ten days after emergence through the V1 growth stage.

Unusually Warm Weather Causes Concern for Early Season Insects and Disease

Author: Denny Cobb

This unusual, warm and dry winter has many corn producers thinking that early season insects or disease may be of greater concern than normal. Even if that happens, our seed-applied fungicides in Escalate™, are selected to offer broad spectrum control, regardless of the weather conditions that may encourage early season corn diseases.

Large Seed and Central Fill Planter Setting Recommendations

Author: Denny Cobb

Low commodity prices have drastically reduced margins this year and the best way to make a profit will be to utilize all of your tools to their fullest potential. That means making sure your planter is ready for the field before its time to plant.

Facing Late Season Challenges

Author: Denny Cobb

For many farmers in my region, the 2016 harvest is a welcome change compared to 2015. Challenges always exist in any given year, but thankfully they were minimal and less severe this year than in 2015.

Marestail Management in 2017

Author: Denny Cobb

Early fall is mostly pre-harvest time in my area. We can evaluate the past growing season and consider possible changes to our operations. One of the most commonly discussed programs this summer has been
the LibertyLink® system for 2017.

Pivotal Month for Corn and Soybean Development

Author: Denny Cobb

August is a pivotal month for both corn and soybean yield development. The developing plants will need plenty of moisture, moderate temperatures, and adequate nutrient translocation to maximize the number, size, and weight of developing kernels/seeds.

Crop Monitoring is Number One Priority

Author: Denny Cobb

Our area struggled this spring during crop establishment. We experienced soil-borne fungal diseases and cool air temperatures coupled with lots of rain, which has delayed growth and development. We had about three planting windows. Amazingly, the earliest planted crops (both corn and soybeans) look the best at this time. The fields needing replanting (additional soybean populations) were completed about June 1.

Addressing Corn Crop Concerns

Author: Denny Cobb

During this time, two major corn crop concerns should be evaluated. The first is stopping first-generation European corn borer (ECB). More unprotected (non-traited or conventional) corn was planted this season than in recent years, creating more host plant acres.

A Plant's First 30 Days

Author: Denny Cobb

Plants need conducive growing conditions all season long for optimal performance. No other period of life is more important than a plant’s first 30 days. That period from seed to a true functioning plant with an active root system needs to be as stress free as possible. What we do or don’t do prior to planting sets the tone for this early growth period.

Reminders for the Field

Author: Denny Cobb

While April field activities commence, there are several key things to remember when you head out to the field. Make sure to avoid soil compaction and plant your corn and soybeans so rapid germination and even emergence take place. The weather last fall was very conducive to correcting the previous seasons’ compaction pains. Now we’re essentially starting with a clean-slate in regards to our soil’s physical condition. It’s said that 75 percent or more of a total season’s compaction is created by the first spring tillage operation. Be mindful of soil moisture conditions at the depth of tillage/planting and what your tractor and equipment axle loads are. Wait to plant until soil temperatures hold a constant 55°F at the 4 in. depth. Both crops will germinate at lower temperatures, though emergence may be less than desired.

Restoring Soil Health After Harvest

Author: Denny Cobb

As harvest progresses, you will see yield variabilities that are unparalleled. For many farmers, this will be a first time experience! You will see hybrids and varieties respond with wide yield swings. Just about any stress you can think of has shown up in our region this growing season. Rainfall intensity and frequent occurrences, planting delays, nitrogen losses, and compaction are the big four. Any one, or a combination of these, will hinder product performance this year.

Helping Cure Compaction and Stagnant Soils with Cover Crops

Author: Denny Cobb

This early fall period gives farmers the opportunity to implement management practices that will benefit them during the 2016 crop season and beyond. Our agronomic area experienced extraordinary rainfall events this past season. The intensive rain events of 2015 have created surface compaction as well as stagnant soils with limited amounts of oxygen and micro life. Cover crops are an excellent means to help cure these issues.

Monitor And Protect Crop Potential

Author: Denny Cobb

Early corn grain fill will be occurring during this period. Virtually all controllable production practices will have been completed with the exception of monitoring non-GMO corn for second generation European corn borer (ECB) infestations, and treating appropriately. This generation generally occurs mid-July to late-August in our area. Trapping adults proves to be the most accurate method of deciding to treat or not. Second generation ECB can be yield devastating. One borer per plant can reduce yield by 7 Bu./A. or more.

How to Properly Identify SDS in Your Fields

Author: Denny Cobb

In Christy’s final scouting report for the summer, she discusses the Sudden Death Syndrome (SDS) she has been seeing throughout soybean fields in central Indiana. We were pleased to have Christy as our sales intern this summer and hope you have found her scouting reports informative. We wish her the best as she heads back to Purdue University for fall classes.

UAV's, NCLB and Japanese Beetles in Indiana

Author: Denny Cobb

As Indiana corn continues to grow, scouting efforts have become more difficult. With some fields averaging over 8 feet tall, patterns are impossible to see from inside the field, which in turn makes diagnosing a field much more difficult. UAV's have proven to be a useful scouting tool in our research this summer, allowing agronomists to see the field from a broad perspective without getting into an airplane or helicopter.

Continue Scouting to Keep Disease and Pests in Check

Author: Denny Cobb

Soybean cyst nematode sampling is best done six to eight weeks after planting. Target fields where yields have plateaued, areas with pH>7, and areas where weed control is lacking.

Soybean Tissue Sampling and Corn Disease Watch

Author: Denny Cobb

With the next round of treatments for soybeans happening soon, tissue samples are critical to ensure the plant is getting what it needs and confirming that we are applying nutrients that will benefit the crop. This week, sales intern Christy Kettler takes us through some best practices when it comes to tissue testing and some updates on the corn diseases she has been seeing throughout central Indiana.
