Tobacco topping and sucker control provides an opportunity for plant to use its maximum potential for leaf development and higher quality and yield production. This study was conducted to determine the best suckercides and optimal amount of them for suckers control. This experiment was performed as a randomized complete block design with seven treatments and four replications in Tirtash Research and Education Center, Mazandaran, Iran. Treatments were prim plus levels (12.5, 15 and 17.5 ml per plant), fatty alcohol 15 ml per plant, fatty alcohol 15 ml with prime plus 17.5 ml per plant, topping and a control (no suckercide, no topped and no suckercide). Cured leaf yield, number of suckers, dry and green weight of suckers per plant, price of one kilogram tobacco and income per hectare, sugar and nicotine percent, burning time and fill capacity were recorded for all treatments. Results of analysis of variance showed significant differences of treatments for the studied traits except for qualitative characteristics. Fatty alcohol 15 ml with prime plus 17.5 ml per plant, prime plus 15 and prime plus 17.5 ml per plant were better treatments with 2925, 2890 and 2745 kg/ha cured leaf yield and 10654, 10418 and 10214 rails price for one kilogram tobacco, respectively.
