In order to investigate the effects of different irrigation regimes on yield quantity and quality of flue-cured tobacco cv. K326, an experiment was carried out based on a randomized complete blocks design (RCBD) with three replications, at Tirtash Tobacco Research Center, in 2011. Treatments were combination of W1= 40%, W2=60%, W3=80%, and W4=100 percent crop water requirement with D1=5, D2=10, D3=15 days irrigation interval with two control treatments (without irrigation (R) and furrow irrigation (I)). The results showed that treatment W4D1, W4D2, W4D3, W3D1, W3D2, W3D3, W2D1, and W1D1 had statistically significant difference with the other treatments and had more dry leaf yield. Also, the minimum leaf chlorine content was observedin W4D2, W3D1, W2D1, W2D2, W1D3, and Rtreatments. Under W4D2, W3D1, W3D3, W2D1, W1D1, W1D2, and W1D3 treatments, tobacco had statistically significant difference with other treatments and had higherprice. Also, the minimum gross income was obtained under W2D2, W2D3, W1D3, I, and R Treatments.
