Two field experiments were carried out at agricultural research center, Giza; Egypt during 2015/2016 and
2016/2017 seasons to study the effect of nitrogen fertilizer levels (20, 30 and 40 kg N/ fed/cut.) on some stevia
varieties (china I, Egy I, spanti and shou2). The highest nitrogen rate of 40 kg. N /fed /cut was significant in all
studied yield andChemical characters and gave the highest values of stevioside%. recorded (6.09 and 6.62%),
,rebaudioside A% ( 7.23 and 8.04%), Stevioside kg /fed ( 238.9 and 286.1 kg) and rebaudioside A kg /fed
(287.2 and 350.5 kg)}, respectively as compared with the other two nitrogen treatments in both seasons.
Stevia Varieties were significantly different in all studied yield characters. china I Varieties gave the highest
values ofstevioside% (6.83 and 7.34 %), rebaudioside A% ( 8.44 and 9.26 %}, rebaudioside A kg /fed(300.8 and
363.2 kg), respectively ofall studied yield and chemical characters except for dry leaves yield kg/fed where EgyI
varieties gave the highest values in the first and second seasons .
. Concerning the effect of the interaction between nitrogen fertilizer levels and stevia varieties on yield and
chemical characters, nitrogen fertilizer level of 40 kg NI fed/cut applied to china I varieties gave the highest values
in all studied yield and chemical composition except for dry leaves yield (kg/fed) where EgyI varieties and
nitrogen fertilizer level of 40 kg N/fed/cut gave the highest values in the first and second seasons.
