Özet
The aim of the present study was to provide reference to the planting time of Burley type tobacco, introduced to Samsun tobacco growing areas in Turkey after the legislative change. For this purpose, yield, quality, income, reducing sugar, nicotine and ammonia properties were examined in plants grown at four different planting times. TN90 variety, which is widely used in the region, was used as plant material. Planting was performed at a density of 40 ×100 cm, on April 15th (DT-1), April 25th (DT-2), May 5th (DT-3) and May 15th (DT-4) in the randomized complete blocks. The average values for yield, quality, income, reducing sugar, nicotine and ammonia were 4,160 kg ha-1, 58.6%, 11,023 $ ha-1, 1.09%, 3.30% and 0.256%, respectively. For all of the parameters examined, decreases were observed in late plantings. For all parameters except ammonia, the ranking was as DT-4
