This study was carried out to investigate application of phosphorous from different chemical, biological and, nano-fertilizers along with spraying of Farselon growth promoting substance on some growth indices, soluble sugars, and nicotine of tobacco in Marivan during 2015- 2016. The experiment was carried out using a split plots and a randomized complete block design with three replications. The main factor consisted of five kinds of fertilizer including control (no fertilization), triple superphosphate, phosphate biological fertilizer (Barvar-2), Nano-phosphate, and combined fertilization (50% Triple superphosphate+ phosphate biological fertilizer + Nanophosphate). The subplot included spraying Farselon growth promotion substance at two levels including: control (distilled water) and Farselon growth promotion substance. Results showed that lower leaves side length, upper leaves side width, middle leaves side dry weight, middle leaves side soluble sugars and nicotine percent were affected significantly by fertilization. The highest lower leaves side lengths were achieved by phosphate biological fertilizer and the highest upper leaves side widths were recorded under phosphate biological fertilizer and nano-phosphate treatment. In addition, the highest middle leaf side dry weight increased in comparison with control as: 11.53, 10.04, 9.58, and 3.99 percent in biological fertilizer, Triple superphosphate, nano-phosphate, and combined fertilization as compared with the control. The lowest nicotine and highest soluble sugars percent were observed in the middle leaves side by combined fertilization. In this study, leaf number, leaf length in lower and middle leaf side, leaf width in upper leaf side, leaf dry weight, cash and nicotine percent in lower and upper leaf side and leaf soluble sugars percent in lower leaf side increased significantly under Farselon treatment.
