اثرات الکل چرب بر روی جوانه های جانبی دو واریته توتون (Nicotiana tabaccum) بارلی 21 و KY907

In order to study the effects of fatty alcohols on two tobacco (Nicotiana tabaccum) varieties, an experiment was conducted at the Agricultural Research Station, Islamic Azad University of Mahabad in 2012. Experiment was conducted as factorial bases on randomized complete block design with four replications. The first factor consisted of fatty alcohols levels (100, 125 and 150 cc), and the second factor comprised two tobacco varieties (burley 21 and ky 907). Traits including leaf yield, leaf length, leaf width, sugar percent, nicotine percent and monetary value were measured. Results showed that there is no significant difference between treatments in term of total traits. The highest yield of leaf is belonged to burley 21 variety when 150 cc fatty alcohol was used. Also the lowest yield of leaf is belonged to ky 907 with 150 cc toxin. In terms of the monetary value, the greatest and minimum income were belonged to burley 21 variety with 125 cc toxin, ky 907 with 150 cc toxin, respectively. Therefore, according to toxin costs and its effects the ky 907 variety of tobacco by applying 125 cc fatty alcohol is advised.
