IMG_1778Observing canopy characteristics during the growing season is a good way to understand the plant’s response to its environment.  Occasionally, portions of the canopy may develop reddish-purple or red tones.  The synthesis of anthocyanin, the pigment which typically causes the reddening, is commonly increased after leaves are exposed to light following multiple abiotic and biotic stresses.  Continue reading

ARTICLE OVERVIEW 

  • Sulfur deficiencies are starting to show up this year in TN cotton.
  • Deficiencies appear as uniform chlorosis of new growth, slight stunting
  • Soil applied applications of ammonium sulfate can still remedy the deficiency 
  • Late season deficiencies can be addressed with (2) applications of magnesium sulfate (Epsom salt)
  • UT currently recommends 10 lb S per ac for cotton
Ames Plantation, TN S plots
LEFT: New growth of sulfur deficient cotton will appear uniformly chlorotic (yellow) and may be stunted. This row received no S at planting. RIGHT: Applications of 10-20 lb S per acre have been shown to prevent the deficiency. This plot received 20 lb S at planting.

Sulfur (S) deficiencies are beginning to appear in some West TN cotton fields.  The image above was taken last week at Ames Plantation in a trial conducted by Dr. Frank Yin.  Although the soils at that location (Collins fine sandy loam) are coarser than our typical silt loam, I was surprised to see such a strong response to the nutrient by Continue reading

Managing cotton plant growth in 2016

Many fields in West TN reached first flower well-before the 4th.  I wouldn’t be surprised if over half of our acres will be blooming by the end of the week.  With rain and warm temperatures in the forecast, expect very rapid plant growth in areas which have adequate moisture as we move into flowering.  For those who have not applied an early shot of a plant growth regulator (PGR), you should consider doing so very soon.  Several points should be considered when attempting to regulate growth in 2016.

Cotton Planting Forecast

Author: Tyson Raper, Cotton & Small Grains Specialist Comments Off on Cotton Planting Forecast

I’ve spoken with several who planted a few fields last week.  Soils have been a little cooler than we would prefer but it was hard to keep the planter at the shop with 60+ degree soil temperatures at 3” at 8 AM with warm temperatures in the forecast.  Moisture is currently not hard to find in most areas given you caught some of the showers Continue reading
