Six cultivars of burley tobacco were grown in late rainy season to compare yield and quality. The field experiment was conducted at Tambon Pak Khawe, Amphor Muang, Changwat Sukhothai from December 1992 to May 1993. The trials were laid out in Randomized Complete Block Design with four replications. The cultivars were: Burley 21, Burley 21*Ky 9,Ky 14,Ky 14*L 8, R 610 and TN 90. TN 90 gave the highest yield and value of cured leaves at 571 kg per Rai and 20,035 Baht per Rai, respectively, which were significantly different from the others cultivar. Ky 14 gave the lowest yield and value of cured leaves. The chemical analysis of cured leaved was showed that TN 90 gave the highest levels of nicotine and total volatile base at 5.36 and 1.14 percent, respectively. The levels of nicotine and total volatile base at 5.36 and 1.14 percent, respectively. The levels of nicotine and total volatile base of all cultivars were 3.99-5.36 and 0.93-1.14 percent, respectively. The ratios of nicotine ammonia to total volatile base were 0.44-0.57.
