Two field trials were conducted at Kaha Farm of Horticultural Research, Kaluebia
Governorate during the two successive summer seasons of 2001 and 2002 to study
the effect of cutting frequency; i.e. without cutting, one cut and two cuts and active dry
yeast i.e. 0, 0.1, 0.2 and 0.3%, as well as their interaction on growth parameters, seed
yield and its components, in addition to seed quality of Jew's mallow cv. 8alady.
Obtained results could be summarized as follows:         1-     Cutting frequency caused significant increase in number of branches per plant
and significant reduction in plant height. The cutting once was the most effective
treatment in increasing seed yield components traits expressed as number and
weight of pods, number of seed per pod, seed yield per plant and seed yield per
fed.; as well as seed index (weight of 1000 seed). On the other hand, these
treatments had no significant effect on germination percentage and rate.         2-     Spraying Jew's mallow plants with the solution of yeast enhanced number of
leaves, leaf area, fresh or dry weight per plant as well as plant height, number of
branches, seed yield and its components and seed index (weight of 1000 seed)
while, the germination percentage and germination rate were not affected by the
these treatments. The most favorable treatment in this respect was yeast at
0.3%.         3-     The interaction between cutting frequency and foliar spray with yeast exhibited
significant effect on all studied characters, except seed quality expressed as
seed index, germination percentage and rate, where this trait was insignificantly
affected by this interaction in both seasons. Generally, it may be concluded that the interaction between cutting plants once with
spraying 0.3% yeast was found to be the best treatment for the production of highest
dry seed yield, such treatment could be recommended.
