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.
Information regarding cotton management following an off-target auxin event has been requested by several producers in our area. This blog briefly covers factors which can impact the yield penalties associated with auxin injury and best management practices after the injury occurs. 
Reports of blanks in wheat heads began trickling in last week and by this week became common. The impacted areas appear to run northeast from Hardeman/Fayette Counties through Madison county and into Henry County. The injury I’ve observed has ranged from light to severe, with the worst injury appearing on acres that were planted in early October. From the windshield, the injury will likely not be noticeable; at a distance, the wheat may simply appear to be maturing rapidly (see image above). Estimated yield loss from the picture above equaled 40%. 
Last week was beautiful. As we were all in the midst of figuring out life during unprecedented times, nature appeared to thumb her nose at the COVID-19 pandemic; dogwoods in full bloom, crappie moving into shallow water, tree shaking gobbles echoing through t-shirt temperature mornings. But after almost a week of beautiful weather in West Tennessee, Easter brought a cold and unfortunately hazardous front through the area that will likely stay with us through the week. As I write this on Monday, the forecast for nighttime temperatures sits in the mid to lower 30s for the next several days. These temperatures likely summon difficult memories of the Easter Freeze of 2007. With that in mind, I wanted to pass along a little information that will hopefully put you at ease.
