Boron Deficiency
Boron deficiency is perhaps wrongly accused of more problems than any other nutrient. Boron is very water soluble and deficiency is related to soil type, soil resource regions, organic matter content and timing of lime materials (pH). Symptoms are generally distinct, and descriptions of this disorder are quite similar across a larger range of environments. Petioles of younger leaves will be short and thick, with dark concentric bands along their length. It appears that the gossypol glands line up and arrange themselves in a "coon tail" arrangement. Flowers may also be distorted in shape. With severe boron deficiency, the terminal may be aborted or become deformed. The pith inside petioles of leaves or bolls may turn brown. Boron is required for normal flower development. Flower and boll shedding may increase as the level of deficiency increases.
Local University and Extension recommendations for boron applications should be followed closely. Some states recommend larger quantities of boron than others. In Misssissippi boron is recommended on hill area soils, recently limed soils and low organic matter sandy soils of the Delta. Generally the Delta region does not respond to boron. Sometimes irrigation water will contain sufficient levels of boron. Not all square, flower or boll shedding is due to boron deficiency problems. Follow your local recommendations with this micronutrient.

This summer has not just felt hot and dry; close to half the state is in moderate to severe drought, and temperatures have been mostly in the 90s through all of August.
Mike Brown is the state climatologist and Mississippi State University professor of meteorology. He said much of the northern two-thirds of the state has been fluctuating between drought and being OK.
STARKVILLE, Miss. -- Producers got a behind-the-scenes look at the wide scope of agricultural research taking place at Mississippi State University in an Aug. 6 event.
Cotton planting has all but drawn to a close in Mississippi for the year, with the state seeing an increase to an expected 500,000 acres in 2024. The U.S. Department of Agriculture made that acreage estimate and said the crop was 94% planted by June 9, 2024. Of that acreage, 80% was either in good or excellent condition, with 19% in fair and just 1% in poor condition.
