Seven cultivars of flue-cured tobacco were grown in early and late rainy season to compare the yield and quality at Mae Jo Tobacco Experiment Station, Chiang Mai, from October 1992 to February 1993 and May 1993 to September 1993. The trials were laid out in Randomized Complete Block Design with four replications. The cultivars were: Coker 206, Coker 347, K 326, K 399,NC 27 NF, NC 37 NF , and Va 182. In late rainy season K 326 and Coker 206 gave the highest yield of fresh and cured leaves, respectively. NC 27 NF gave the highest value of cured leaves in the late rainy season. Coker 347 gave the highest yield of fresh and cured leaves and the highest value of cured leaves in early rainy season. NC 37 NF and Va 182 gave the lowest yield of fresh and cured leaves in late and early rainy season, respectively Va 182 gave the lowest value of cured leaves in both planting periods. The chemical analysis of cured leaves was showed that NC 37 NF and Coker 347 gave the highest levels of nicotine when grown in late and early rainy season, respectively NC 27 NF gave the lowest levels of nicotine content in both planting periods. The levels of nicotine were 1.31-3.79 percent and the levels of redcucing sugars were 8.51-27.39 percent in both planting periods.
