Abstract
Abstract A computerized analysis has been conducted to determine the comparative annual costs of various harvesting/market preparation systems for burley tobacco. The CATCH223 model developed at the University of Kentucky computes the annual costs of alternative systems that facilitate harvesting and/or market preparation at a time rate(s) prescribed by a producer or analyst. Harvesting systems that utilized the most manual labor had the lowest annual costs for crop sizes analyzed between 4 and 40 ha, although the advantage of manual vs mechanized systems diminished as crop size increased. On the other hand, the analysis shows that mechanized market preparation systems have consistently lower annual costs than conventional methods that require manual removal and grading of cured leaves. Finally, the analysis shows that a fully automated harvesting system (having the highest projected annual cost of all of the alternatives) can be combined with an automated market preparation system resulting in a total an...
期刊介绍：
Chinese Tobacco Science is an academic scientific journal (bimonthly) under the supervision of the Ministry of Agriculture and Rural Affairs of the People's Republic of China, and sponsored by the Tobacco Research Institute of the Chinese Academy of Agricultural Sciences and the Qingzhou Tobacco Research Institute of China National Tobacco Corporation. It was founded in 1979 and is publicly distributed nationwide. The journal mainly publishes academic papers on scientific research results, new production technologies, and modern management in my country's tobacco science research and tobacco production technology. In addition, it also publishes forward-looking review articles in the field of tobacco research. There are columns such as tobacco genetics and breeding, cultivation technology, modulation and processing, physiology and biochemistry, plant protection, review or monograph, quality chemistry, etc.
