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.
ELLISVILLE, Miss. -- Mississippi State University representatives met with agricultural clients in Ellisville recently to discuss research and education needs for 2018. More than 115 individuals attended this year's event.
STARKVILLE, Miss. -- Two highly anticipated online training modules are now available for those who plan to purchase or apply dicamba and similar herbicides.
The Mississippi State University Extension Service, in cooperation with the Mississippi Department of Agriculture and Commerce Bureau of Plant Industry, developed these new online training courses related to herbicides labeled for use with dicamba-tolerant cotton and soybeans in response to label changes from the Environmental Protection Agency.
STARKVILLE, Miss. -- In response to new Environmental Protection Agency regulations on the use of the herbicide dicamba, the Mississippi State University Extension Service is developing two online training courses to help cotton and soybean farmers follow the new rules.
STARKVILLE, Miss. -- The 2017 production value of Mississippi’s four largest row crops is forecasted to outperform the previous year by more than 7 percent.
Brian Williams, agricultural economist with the Mississippi State University Extension Service, predicted the combined value of soybeans, cotton, corn and rice will be nearly $2.1 billion this year. The total projected value for all agronomic crops is $2.5 billion, which would be a 6.4 percent increase over the $2.4 billion value reached in 2016.
STARKVILLE, Miss. -- Cover crop usage is gaining momentum on Midsouth farms and will be a major focus of the 2017 Mississippi State University Row Crop Short Course.
The MSU Extension Service will host the course at the Mill Conference Center in Starkville Dec. 4-6.
