الملخص EN

This study were conducted on transplant of two fig cultivars "white adriatic" and "aswad diala", which were planting on plastic pags under lauth house conditional Horticulture and Landscape Design, throw 2012 growing season, to know the effect of foliar spray with two levels of each of liquid fertilizer Starter plus (8% N-32% P - 5% K) (1 and 2 ml.L-1), Zn (5 and 10 ml.L-1) and IAA(50,100 mg.L-1) in addition to control treatment.

The foliar sprays of all factors were done of three times (21/5, 5/6 and 20/6), 15 days intervals.This study were conducted by using C.R.D Design, with three replicates and with four transplants for each experimental unit, The means were compared by using Duncan multiple range test of probability of 5%.

Results indicated that the foliar spray with liquid fertilizer Starter plus of two concentrations (1 and 2 ml.L-1) significantly increased leaves chlorophyll content and increment of main stem height respectively.The foliar spray with zinc with concentration (5mg.L-1) significantly increase the increment of leaves number and with concentration (10 mg.L-1) significantly increase the increment of main stem diameter.

The results clearly showed that "white adriatic" cv.

Significantly dominated over "aswad diala" cv.

in all studied parameters except dry matter percentage.

The interaction effect showed that "white adriatic" transplants which were sprayed with 2 ml.L-1 of Starter plus significantly increased all studied parameters compared with other interaction
