Abstract

Two field experiments were carried out during the two successive summer
seasons of 2002 and 2003 to investigate the effect of 4 levels of nitrogen fertilizer (20,
30, 40, and 50 N unit/fed.) and 4 levels of potassium fertilizer (12, 24, 36 and 48 K
unit/fed.) on vegetative growth characters, foliage yield and its some chemical
composition of Jew's mallow plant.
The important results could be summarized as follows:
1-lncreasing nitrogen fertilizer levels up to 50 N unit/fed. significantly increased
vegetative growth and total foliage yield as well as N, P and K contents of its
leaves tissue.
2-lncreasing the levels of potassium fertilizer addition up to 48 K unit/fed. enhanced
vegetative growth characters and total foliage yield as well as increased N, P and K
contents in leaves tissue.
3- The vigor vegetative plant growth and the heaviest total foliage yield were
associated with the highest nitrogen level (50 N unit/fed.) combined with the highest
potassium level (48 K unit/fed.).
