Effect of time and values of methanol foliation on growth and yield of Coker 347 type tobacco

To investigating the effect of methanol on growth and yield of Coker 347 type tobacco a factorial design based on RCBD with 4 replications and 18 traits was don during 2008-2009. Factors were considered as the methanol consumption time in as first factor which was consist of three solution spreading surface in the morning (Time 8-10 am) (T1) and noon (Time 12-14) (T2) and sunset (Time 17-19pm) (T3) and the second factor was the amount of methanol consumption as 0، 30، 20، 10، 40، 50 volume percent of methanol. Solution spreading of methanol during the growing season respectively performed at the beginning terms of quick transplants growth، blossom origination and 30 days before illustrating of tobacco plants. Tobacco product harvested in three sorts. Results showed that the LA، chlorophyll and the plant height became significant at the interaction effect of the two factors (p<1%) but the number of leaf in interaction effect became significant at p<5%. Sugar and Nicotine became significant at the factor B (p<5%) but leaf dry weight becomes no significant. Therefore، regarding to these results methanol enhances the quality and quantity of tobacco plant.
