Trends in flue-cured tobacco breeding, 1954-2018

RAMSEY A.F.; VANN M.C.; LEWIS R.S.; FOOTE W.R.; REJESUS R.

Virginia Tech, Blacksburg, VA USA

Reference only. Abstract submission was on a voluntary basis....

The effect of chloride application rate to the yield, quality, and chemistry of flue-cured tobacco

PACE C.R.; VANN M.C.; FISHER L.R.; SEAGROVES R.; HARDY D.H.

North Carolina State University, Raleigh NC USA

Applications of chloride (Cl-) to tobacco are generally discouraged due to the negative effects the anion can have to yield, quality, and smoke flavor/aroma. Despite the negative effects associated with Cl- application, unintentional applications of...

Organic transplant production: an evaluation of nitrogen fertility programs

VANN M.C.(1); FISHER L.R.(1); SEAGROVES R.(1); McGINNIS M.(2)

(1) North Carolina State University, Raleigh NC USA; (2) North Carolina Department of Agriculture and Consumer Services, Raleigh NC USA

Organic tobacco production in North Carolina has increased in recent years. Despite increasing interest, little is known regarding the appropriate management of organic nitrogen sources in a seedling float system. Research was conducted to evaluate...

Evaluations of float water aeration in organic transplant production

FISHER L.R.(1); VANN M.C.(1); SEAGROVES R.(1); McGINNIS M.(2)

(1) North Carolina State University, Raleigh NC USA; (2) North Carolina Department of Agriculture and Consumer Services, Raleigh NC USA

At present, the effects of float bed aeration in the production of organic tobacco seedlings are not known. Research was conducted to evaluate two organic nitrogen fertilizer programs and their effects to float water nutrient concentration and...

Screening of acidifying chemicals for use in the production of organic tobacco seedlings

VANN M.C.(1); SEAGROVES R.(1); SHORT M.(1); McGINNIS M.(2)

(1) North Carolina State University, Raleigh NC USA; (2) North Carolina Department of Agriculture and Consumer Services, Raleigh NC USA

Float water bicarbonate concentration in excess of 2.0 meq/L (100 ppm) can result in stunted, unusable seedlings unless float water is acidified. In conventional greenhouse systems, sulfuric acid is used for this purpose; however, that chemical is...

Evaluation of S-metolachlor for use in flue-cured tobacco production

CLAPP A.; VANN M.C.; FISHER L.R.; INMAN M.D.

North Carolina State University, Raleigh NC USA

With limited herbicide options and a growing concern to herbicide-resistant weeds, there is a strong need for additional chemical weed control materials in tobacco. S-metolachlor is labeled for use in a variety of agronomic and horticultural crops in...

Simulated sprayer tank contamination with Dicamba

INMAN M.D.; VANN M.C.; FISHER L.R.; GANNON T.W.

North Carolina State University, Raleigh NC USA

The deregulation of dicamba-tolerant cotton and soybean has increased the potential for dicamba exposure to tobacco through drift or tank contamination. Improper cleaning of sprayer equipment and off-target dicamba exposure can have detrimental...

The effect of leaf removal number and subsequent nitrogen application on yield, quality, and value

FINCH C.E.; VANN M.C.; FISHER L.R.; WELLS R.; BROWN A.B.

North Carolina State University, Raleigh NC USA

Research was conducted in North Carolina to quantify the impact of the number of leaves removed at topping and the subsequent application of four rates of liquid nitrogen. At topping, either 0, 4, or 8 leaves were removed from the lower stalk...

Assessment of a stalk applied MH spray system installed on a mechanical harvester

ELLINGTON G.H.; MACIALEK J.A.; VANN M.C.; ROBERSON G.T.

North Carolina State University, Raleigh NC USA

Current maleic hydrazide (MH) applications on flue-cured tobacco require spraying over the top of the plant to insure proper coverage and effectiveness, but depending on a number of factors the cured leaf residues can be elevated and negatively...

Evaluation of NCDA boron sufficiency ranges for flue-cured tobacco

JERNIGAN C.(1); HARDY D.H.(1); HICKS K.A.(1); McGINNIS M.S.(1); FISHER L.R.(2); VANN M.C.(2)

(1) North Carolina Department of Agriculture and Consumer Services, Raleigh NC USA; (2) North Carolina State University, Raleigh NC USA

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...
