-: Okay, my name is Jim Specht,
professor in agronomy, now retired,
at the University of Nebraska,
and my specialty was soybean physiology and production
in addition to genetics genomics,
but today we're gonna focus on physiology
in production of soybean.
Okay, again, we're back to soybean management practices
and two key issues are what sort of seeding depth
should you use to optimize your seedling emergence
and what kind of seeding rate are you gonna use
to obtain what you desire as our final plant,
density at maturity.
So we're gonna talk about that, seeding rate and depth.
Here's a survey of soybean producers in Nebraska
under irrigated and rain fed.
As you can see here,
most of the soybean producers in this survey
plant soybeans at around 135,000 seeds per acre,
which is higher than the recommended rate of about 120,000.
You can see irrigate...
