The field experiments were conducted during the two successive summer
Seasons of 2002 and 2003 at Kafer EL-wekala , Sherbin, Oakahlia, Egypt, to study the
effect of foliar nutrition of potassium citrate and Fe-chelate on growth and yield of
eggplant, c.v. Black beauty. The experiment contained 9 treatments, which were the
simple combination between 3 levels of potassium citrate (0, 1.5 and 3 gIL) and iron
chelate (0, 1 and 2 gIL). The main findings obtained from this investigation showed
that dry weight, leaf area, total chlorophyll, average fruit weight and number of fruits
per plant as well as total yield per feddan were significantly increased by foliar
application of 3 gIL of potassium citrate and 2 gIL of Fe-chelates.
