Burley tobacco (Nicotiana tabacum L.) production in Kentucky is typically tillage-intensive and sometimes mono-cropped. Intensive tillage has been reported to degrade soil structure and deplete soil organic carbon (SOC) and total nitrogen (TSN) stocks. ...

Approximately 75% of tobacco production in Virginia is grown in fields classified as highly erodible. Strip-tillage, which has been demonstrated to be suitable for tobacco in southern Virginia, utilizes specialized equipment to cultivate narrow strips ...

Boron (B) is an essential micronutrient for optimum plant growth of flue-cured tobacco and is required in trace amounts (<1.0 lb B/acre). Since use of premium tobacco fertilizer grades that contain trace amounts of B are not typical in today’s ...

Boron deficiency has been documented on several farms in the dark tobacco production area of Kentucky and Tennessee, most commonly in the Purchase Area of Kentucky (Murray/Mayfield KY area). Typical symptoms of boron deficiency include leaf breakage ...

Field experiments were conducted in 2012, 2013, and 2014 to evaluate dark tobacco response to potassium at a site near Murray KY that showed low to medium potassium levels in soil samples taken in the spring prior to tobacco transplanting. Soil test K at ...

Owing to particular properties such as surface effect, volume effect and quantum size effect, nanomaterials can enhance chemical fertilizer efficiency and promote plant growth. Carbon nanosol, which is produced by graphite electrolysis, also showed ...

Current recommendations for nitrogen application to flue-cured tobacco are two separate application timings; one-half rate applied after transplanting and one-half rate applied at layby. A result of this practice is the likelihood of too much nitrogen ...

Nicotine is one of the most studied and scrutinized plant secondary metabolites. Its concentration in tobacco products now falls under the jurisdiction of the Food and Drug Administration and it has been speculated that increased regulation might occur. ...

Organic tobacco production presents a small but apparently growing niche market for tobacco growers. Among the challenges for organic tobacco growers is the production of healthy viable transplants. Most organic tobacco growers would prefer to use float ...

Greenhouse float tobacco transplant production has long been the standard of the tobacco industry both in the U.S. and in other areas of the world. The expanded polystyrene (EPS) tray is the foundation of the float production system. However, effective ...
