| Abstract | ||||
| Pot experiment was conducted in greenhouse on stevia plant to study the effect of both ammonium and potassium nitrate under the treatments of BA., Kin, and TDZ on both growth and chemical constituents. Leaf chemical composition of P, N, K and protein as well as chlorophyll% were determined during 2016 and 2017 seasons. Ammonium nitrate excelled potassium nitrate fertilization on all growth characters except plant height. B.A. treatment tended to increase total fresh weight/ plant as compared to those of Kin and TDZ in some cases. K con. was higher centration under potassium nitrate fertilization when compared to ammonium nitrate fertilization. Potassium nitrate addition resulted in slight increase in chlorophyll a & b and carotenoids over ammonium nitrate addition.
