عنوان انگلیسی Studing the Effect of time and values of methanol foliation on quality and quantity yield flue-cured tobacco of cocker 347 type in Ahmadgurab region of Rasht
چکیده انگلیسی مقاله In order to study the effect of methanol on growth and yield of Virginia tobacco varieties Cocker 347, an experiment was carried out through a factorial experiment in Randomized complete block design with 4 replications and 18 treatments. First Treatment was spraying time which includes 3 levels, sprayed in the morning (8-10 hours) and noon (12-14 hours) and evening (17-19 hours) and the second treatment was methanol consumption values that include 6 levels of consumption values 0, 10, 20, 30, 40 and 50 percent. Methanol sprayed at 3 times during the growing season, respectively, in the rapid growth of transplant, budding and 30 days after budding of tobacco plants. Tobacco was harvested in 3 fold. The obtained results of the data analysis showed that interaction of two factors had significantly effect on the phosphorus, potassium and nitrogen values as well as RWC at 1 percent level. Leaf width was significant in different values of sprayed methanol at 5 percent level but leaf length was significant in values of sprayed methanol at 1 percent and fresh weight and stem diameter were not significant. According to the result can be concluded that methanol improved qualitative yield of tobacco but not affected Quantitative yield of tobacco.
