Abstract EN
A study was conducted in Al-Seba Reserve / Basra Governorate to study the effect of nitrogen and potassium fertilization on growth of stevia plants during 2018-2019 agricultural season, in pots.
A sandy mixture of soil was used and two factors were studied: the first factor was urea fertilizer with five levels of nitrogen (N0 0, N1100, N2150, N3 200, and N4 250 kg / ha) and the second factor was potassium sulfate with three levels of potassium (K0 0, K1 75 and K3150 kg /h (.
The experiment was experimental factor using a complete randomized design (C.
R.
D) with three replications.
The results showed a significant effect of adding nitrogen and potassium fertilizers and there interaction on: plant height, number of branches, leaf area index, and the treatment N3K2 gave the highest yield reached (1.27 tons.
h-1), and N4K2 recorded a highest content of Rebaudioside A (53.26 ppm).
