The study looked at how the height at which tobacco plants are cut, their maturity level, and the type of cultivar affect the quality and price of the tobacco. They found that in years with different weather conditions, the price and quality of tobacco varied. Overripe tobacco had the best ratio of reducing sugars to nicotine in the first two years, but in 2007, delayed maturing led to poor quality. The total nitrogen to nicotine ratio was good in all years, with higher ratios in the best weather year. The N-protein to nitrogen ratio was acceptable in ripe tobacco, but only in overripe tobacco in 2007. Different tobacco cultivars also had a significant impact on quality. Overall, the study showed that weather, maturity, and cultivar all play a role in determining the quality of tobacco.
