Irrigation Termination Decisions for Corn and Soybean

Author: and  Comments Off on Irrigation Termination Decisions for Corn and Soybean
As we approach the end of July, much of our corn and some of our soybean acres are in the latter portion of their respective reproductive growth stages. As we progress toward physiological maturity, lets revisit irrigation termination decisions for these two crops.

Cotton Specialists’ Corner Podcast: PGR use on dry acres, farms with mixed maturity

Author:  Comments Off on Cotton Specialists’ Corner Podcast: PGR use on dry acres, farms with mixed maturity

We are quickly approaching the period of time in which we typically apply PGRs.  Unfortunately, May was not kind and June has been dry.  Many are struggling with figuring out when to start PGR applications and how aggressive we should be with that first application.  In this blog, I link to our most recent Cotton Specialists’ Corner podcast on this very issue.  This episode highlights several things to keep in mind before we run a stiff rate of PGR to an already stressed plant and potentially hurt yields.

If you haven’t noticed, our UTcrops.com website has gotten a facelift.  You may not recognize it when you first visit us at  https://utcrops.com/.  However, it’s organized similarly to the old version.  I’m sure there are a few bugs that need to be fixed, but take a look!  This site gives you ready access to essentially all UT resources related to row crop production.

Cotton growth stages and water requirements

Author: and  Comments Off on Cotton growth stages and water requirements

While May brought a great deal of rain, June and July have been dry for much of West Tennessee.  We are already beginning to see the impacts on cotton growth and development.  While we still have very good cotton yield potential, we need a good soaking rain in the coming weeks.  This blog highlights impacts of drought on cotton during the growth stage, provides general information on scheduling irrigation and highlights a few scheduling methods.

Ideally, the soil profile needs to provide sufficient plant available water throughout the blooming period. As we begin to move towards the permanent wilting point during the blooming window, fruit retention may begin to decline and maturity may be delayed.  If a rainfall or irrigation event does not ameliorate the stress, yield penalties may develop.  Cotton plants are particularly susceptible to drought during the early boll development stages which immediately follow flowering (Table 1). Keeping soil profile at or near field capacity at early bloom through peak bloom will support earliness and maximize yields.
