As a young agronomist, one of the first things I learned was that when assessing corn emergence and stand establishment following planting, is that it is always important to have a shovel with you.
Dan Quinn
Once the corn seed is planted, the waiting game for the first corn plants to emerge begins, which also means assessing (or worrying) if any issues had occurred.
As spring approaches and farmers and agronomists begin to get anxious as corn planting approaches, the question that often arrives each year is when is the best time to begin planting?
Sulfur Deficiency
Sulfur (S) deficiency has become more common in
Indiana crops because S emissions from coal-fired power
plants have decreased over the past few decades
(Camberato et al., 2022). Consequently, atmospheric S
deposition to soils has also decreased.
Sulfur deficient corn plants exhibit a general yellow-
green color from top to bottom of the plant, often also
with visible leaf striping (Fig. 1). Other nutrient deficiencies
can cause striping and can sometimes be confused with S
During the heat of planting, one thing that often can be forgotten is thoroughly checking and understanding two items, 1) what seed depth am I planting at? and 2) is my seeding depth consistent, especially across all of my individual row units?
Field research trials are an important part of understanding how specific agronomic practices can improve farm productivity.
On this episode, Shaun and Dan talk about the slow start to the harvest season and some early soybean yield numbers.
Although yield is always at the forefront of many corn farmers and agronomists’ minds during harvest, another important discussion topic each fall is that of grain test weight.
Each year as corn harvest approaches and the anticipation for finally being able to get behind the wheel of the combine heighten, it is not uncommon to find work benches, dinner tables, and agronomist office desks full of corn ears.
On this episode of the Purdue Crop Chat Podcast, Purdue Extension Soybean Specialist Shaun Casteel and Corn Specialist Dan Quinn welcome Indiana State Climatologist Beth Hall to discuss the weather extremes farmers have faced and might continue to face this season.
