The Effect of Mycorrhiza and Foliar Application of Zinc, Boron, Potassium Elements on Agronomic Characteristics and Quality of Tobacco

The effect of mycorrhiza and foliar application of Zinc Boron Potassium elements on agronomic characteristics and quality of tobacco was studied at Marivan- Bilo tobacco field during 2014- 2015. The experiment was split plots based on randomized complete block design with three replications. The main factor with two levels of inoculation by mycorrhiza (Glumus interaradices) including control (no inoclution) and inoclution by mycorrhiza and subplots were foliar application of micro and macro elements in 5 levels including control as distilled water, Zinc, Boron, Potassium, Zinc Boron Potassium. The results showed that in middle leaf of plant some traits such as leaf fresh and dry weight and in upper leaf, leaf cash were decreased significantly. Mean comparison of lower leaf side were obtained that the maximum value of leaf dry weight were achieved by foliar application of zinc. Also in middle leaf, the maximum values of leaf dry weight were obtained by Boron and also the maximum leaf fresh weight by zinc. Finally in upper leaf, the maximum dry weights and leaf cash were affected by Potassium foliar application.
