Abstract
Abstract Time periods during the burley growing season were identified when increases or decreases in available moisture had significant influences on burley crop yield and crop quality. This was accomplished with the use of 42 years of daily precipitation and evapotranspiration data (1959–2000) along with the yearly crop yield data for the Kentucky locations of Louisville, Lexington, and Paducah. Crop quality was defined with the use of 3 leaf color groups—tan, red, and green—and a yearly grade index, and these were determined from Kentucky statewide sales percentages for the period of record. Available moisture was defined as the difference in daily precipitation and evapotranspiration, and this difference was used to define a growing-season available moisture index (AMI) for each year in the period of record. Correlation procedures were used to search the growing season for time periods when increases or decreases in the AMI resulted in significant increases or decreases in the various color groups and...
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.
