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 (chinal, Egyl, spanti and shou2) growth characters in both seasons. The highest nitrogen rate of 40 kg.
N /fed /cut was significant in all studied growth and yield characters and gave the highest values as compared
with the other two nitrogen treatments in both seasons.
stevia varieties were significantly different in all studied growth and yield characters. Egyl varieties gave the
highest values of all studied growth and yield,characters except for Plant height and number of branches per plant
where spanti cultivar gave the highest values in the first and second seasons.
Concerning the effect of the interaction between nitrogen fertilizer levels and stevia varieties on growth
character values, nitrogen fertilizer level of 40 kg N/ fed/cut applied to Egyl varietie gave the highest values in
all the three cuts studied except those of plant height and number of branches in both seasons.
