ABSTRACT
In order to investigate the effect of nitrogen and potassium fertilizers on yield of flue-cured tobacco cv.Coker347, 2 years experiment was carried out in Tobacco Research Institute of Rasht city located in Guilan province on factorial based using a factorial experiment with 8 treatments and 3 replications. The applied fertilizer levels included 35(N1), 45(N2), 55(N3) and 65(N4) Kg N/ha as urea source and potassium in two levels of 150(K1) and 200(K2) Kg K/ha potassium as potassium sulphate source. The measured parameters in this experiment included dry leaf yield, stem height, stem diameter, leaves number, leaf length, leaf width, stem dry weight, biomass, flowering, nicotine and sugar content. levels of 65 Kg N/ha and 200 Kg K/ha had the highest amount of dry leaf yield. The greatest number of leaves and leaf length were associated with using 55 Kg N/ha and 200 Kg K/ha as well as using 65 Kg N/ha and 200 Kg K/ha. Applying 65 Kg N/ha and 200 Kg K/ha, 55 Kg N/ha and 150 Kg K/ha indicated the highest amount of biomass.
