Economic factors influencing lower-leaf removal decisions

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

North Carolina State University, Raleigh, NC USA

With a current global over-supply of flue-cured tobacco, tobacco producers in North Carolina have been encouraged to remove the lowermost leaves prior to harvest due to their low value in manufactured products. In field trials, the removal of 4 or 8...

Lower-leaf removal programs for flue-cured tobacco production in North Carolina

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

North Carolina Cooperative Extension Service - Davidson County, Lexington, NC USA

Sluggish demand for lower-stalk positions has prompted consideration for de-lugging programs in North Carolina. The agronomic impact of these leaf removal systems has not been fully reported. The objective of this research was to compare lower-leaf...

Comparisons of nitrogen based fertilizer programs in tobacco

SHORT M.M.; VANN M.C.; CHEEK J.A.; WHITELY D.S.

North Carolina State University, Raleigh, NC USA

Previous fertilizer research in flue-cured tobacco has compared a wide range of nitrogen (N) based programs, ultimately demonstrating the usability and function of numerous sources. However, those research efforts have not fully investigated the...

Effects of chloride application to nutrient assimilation and post-harvest measurements of flue-cured tobacco

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

North Carolina State University, Raleigh, NC USA

Chloride (Cl-) application in excess of 34 kg/ha has generally been discouraged in the production of US flue-cured tobacco, due to the negative effects the nutrient can have on cured leaf yield, quality, and smoke sensory. However, fertilizer...

Efficacy of S-metolachlor based herbicide programs in flue-cured tobacco

BRADLEY A.; VANN M.C.; CAHOON C.W.; JORDAN D.L.; INMAN M.D.; CLAPP A.M.

North Carolina Cooperative Extension Service - Edgecombe County, Tarboro, NC USA

Maximized weed control is critical to the growth and development of flue-cured tobacco. Currently, the PPO-inhibiting herbicide sulfentrazone is the primary control option for Amaranthus, Cyperus, and Ipomea weed species. With the current risk of...

Pelargonic acid - the nuclear option for sucker control??

VANN M.C.; WHITELY D.S.; CHEEK J.A.; MACHACEK J.L.

North Carolina State University, Raleigh, NC USA

Chemical alternatives to fatty alcohol for tobacco sucker control have recently been evaluated in North Carolina. Pelargonic acid is a fatty acid used for weed control in conventional and organic crops that has been proposed as a suitable candidate...

Evaluation of S-metolachlor application timing and rate in flue-cured tobacco

VANN M.C.; WHITELY D.S.; JORDAN D.L.; CAHOON C.W.; INMAN M.D.; CLAPP A.M.

North Carolina State University, Raleigh, NC USA

The current risk of PPO herbicide-resistant Amaranthus palmeri creates a need for additional herbicides in tobacco production. Field experiments were conducted to evaluate flue-cured tobacco tolerance to S-metolachlor applied Pre-Transplant...

A modern approach to fieldnotes, barcoding, and electronic data capturing

MACHACEK J.; VANN M.C.; LEWIS R.S.; BRINTON C.; HUMMELL N.; RATHBONE K.

North Carolina State University, Raleigh, NC USA

Physical means of data collection and note taking can be laborious and costly. A modern approach to fieldnotes utilizes electronic data capturing technology. With a few simple tools and software, pre and post-harvest measurements can be automaticly...
