Effect of macro elements on some traits of flue-cured tobacco cv.Coker347
Journal Title: International Research Journal of Applied and Basic Sciences - Year 2012, Vol 3, Issue 9
Abstract
In order to investigate the effect of macro elements on yield and some quantitative traits of flue-cured tobacco cv.Coker347 an experiment was carried out in tobacco research institute of Rasht located in Guilan province on factorial based with 3 replications and 8 treatments. The applied fertilizer levels included 35 (N1), 45 (N2), 55 (N3) and 65 (N4) Kg/ha of pure nitrogen and potassium in two levels of 150 (K1) and 200 (K2) Kg/ha potassium. The measured parameters in this experiment included dry leaf yield (leaf dry weight), green leaf yield (leaf wet weight), leaf tissue hydration, plant height, stem diameter, biological yield (biomass) and harvest index. According to obtained results, effect of nitrogen on dry leaf yield, green leaf yield, and biomass was significant (P<0.01). Nitrogen had also significant effect on plant height and stem diameter (P<0.05). Potassium had significant effect on dry leaf yield and biomass (P<0.01). Potassium had also significant effect on green leaf yield and plant height (P<0.05). Interaction between nitrogen and potassium was significant on dry leaf yield (P<0.01).
