ABSTRACT

In order to study the effects of seedling age on yield and yield components of tobacco (Nicotiana tabacum L.), a field experiment was carried out in the field of Bilatie tobacco farm in the period of 2014–2015. Experimental design was arranged in Randomized Completely Block design with three replications. Results showed that the effect of seedling age on plant height, leaf length, width, stem diameter per plant and green leaves yield per plot was significant at 0.05 probability levels. Early seedling age 6- 11 weeks or 45-77days were produced larger leaves, greater number of leaves, more stem diameter per plant, higher green leaf yield per plot , grew taller and less exposed to virus diseases than the seedlings transplanted at (12 - 14 weeks ) or (84- 94 days). It is recommended that tobacco should not be left beyond 12 weeks or 84 days in nursery before transplanting for optimum performance.

Key words: tobacco, green leaf yield, seedling age, yield component
