Abstract

In order to effect of furrow irrigation with one and two rows and nitrogen fertilizer on yield quality and quantity of Virginia tobacco variety cocker 347, an experiment was carried out through split plot based on randomized complete block design with three replication and nine treatments at the Research Station Tobacco Center Rasht, Iran in 2010. Treatments were nitrogen fertilizer (45, 55 and 65 kg/ha as the main plot) and furrow irrigation (elimination of irrigation from one of two rows, irrigation of all rows, and no irrigation as sub plot). The highest leaf yield, respectively, in one row irrigation and 55 kg of nitrogen fertilizer, two rows irrigation and 55 kg nitrogen fertilizer and two rows and 65 kg of nitrogen fertilizer were respectively, with values of 3864 and 3676 and 3220 kg ha are the highest yield. Results from analysis of data showed that the relative nitrogen, phosphorus uptake, leaf yield and SLA were significant at 1 percent levels in irrigation, but potassium uptake and Leaf nicotine was significant at 5 percent levels in irrigation treatments comparison between furrow irrigation with one and two rows shows that irrigation with two rows has a higher yield. Comparison between nitrogen fertilizers also shows that the amount of 55 kg of nitrogen fertilizer more affected quantitative of tobacco and 65 kg of nitrogen fertilizer more affected qualitative of tobacco. We can be concluded that optimum utilization of water resources cans improvement qualitative and quantitative of tobacco plants.
