Sažetak
Response of cigar tobacco (Nicotiana tabacum L.) in morphological, agronomic and chemical characteristics to date of planting and planting distance was studied during 1971-73. A cultivar and a breeding line of cigar tobacco were transplanted outdoors on 26 May, 9 (or 12) June and 23 June. The tobacco was spaced 36, 41 and 46 cm in rows that were 97 cm apart. The best results were obtained when cigar tobacco was transplanted not later than 9 June, and the plants were spaced 41 cm in the rows that were 97 cm apart. The highest number of leaves per plant, cured-leaf yield, percentage of nicotine and total alkaloids were obtained from the tobacco transplanted on the first or second date in 3 yr. In 2 yr, the later tobacco had the tallest plants, the largest leaves, the highest percent filler leaf, grade and crop index. Earlier-transplanted tobacco was harvested earlier, although the period to flower decreased with later date of planting. On the average, the tobacco spaced 41 cm was taller and had a shorter period to flower, and higher yield and crop index than that spaced 36 cm or 46 cm. Grade index, percent filler leaf, nicotine and total alkaloids were affected significantly by the distance in 1 yr only.
