First report of cigar tobacco production in western North Carolina

Abstract

Over the last two decades, burley tobacco (Nicotiana tabacum L.) production has declined by 5,300 acres in western North Carolina (North Carolina Department of Agriculture and Consumer Services, 2005; USDA-NASS, 2019). The loss of burley tobacco has left a void in the agricultural economy. Cigar wrapper tobacco types, such as Pennsylvania seedleaf (PA41) and Connecticut broadleaf, may be suitable replacements for burley because of their overlapping production practices. Cigar tobacco has not been produced in western North Carolina; therefore, knowledge gaps exist regarding its growth habits in the region. The objective of this study was to quantify the days to flower removal, yield, and grade distribution of six cigar tobacco varieties. 2 METHODS AND MATERIALS In 2019, experiments were initiated at the Mountain Research Station in Waynesville, NC (35.48N,-82.96W) and the Upper Mountain Research Station in Laurel Springs, NC (36.39N,-81.30W).

Locating Defects and Image Preprocessing: Deep Learning in Automated Tobacco Production

“…The principle of deep mining distributed machine learning is to extract some underlying data features by using multiple data hidden layers; each hidden layer is equivalent to only one data perceptron, which can obviously and effectively alleviate the minimum problem of underlying data locally. The depth of the extracted underlying data features can be obtained by using a data perceptron to extract some low-level features and then by recombining all these underlying features to form some more complex and abstract representations of the high-level data, which is a representation of distributed deep learning features [13].…”

Research and Application of Improving the Whole Cut Tobacco Rate in the Mixing Cabinet

“…The whole cut tobacco rate is an important index to evaluate the physical characteristics of cut tobacco, reflecting the quality of silk processing [1] , directly affecting the filling ability of cigarettes, and also affecting the quality indicators of cigarette weight, suction resistance, short head rate and other quality indicators [2][3][4][5] , There are many factors affecting the whole cut tobacco rate [6][7][8] .In addition to the physical properties of the cut tobacco itself ( moisture, temperature, etc. ), the effect of the whole cut tobacco rate of the mixing cabinet after flavoring is the most significant.…”
